(1) Digging machine and operation The digging machines used in the city include 3W1-80 type and IW-0.7 type. The following describes the 3W1-80 type as an example. The digging machine is mainly composed of four major parts. Vertical lifting mechanism: mainly used to ensure the vertical lifting of the excavation head and in any working position, the excavation head axis and the locomotive distance remain unchanged. It consists of a curved plate and a swivel arm. Universal joint drive shaft assembly: used to drive torque, equipped with a claw-type safety clutch in the middle of the joint, when the work suddenly encountered obstacles, the load exceeds the allowable value, the spring is compressed, the teeth embedded The gears skid, which cuts the power and prevents the parts from being damaged due to overload. Transmission assembly: It consists of a pair of bevel gears. This gearbox is mainly used to change the direction of power transmission and reduce speed, increase torque. Excavation head: It is the working part of the digging machine. A square shaft sleeve is connected to the square shaft on the vertical axis of the gear box above the drill shaft, and the two are positioned with a pin. The excavation head is forced into the soil by means of a tractor hydraulic lifting mechanism during work. The 3W1-80 model is compatible with the Tie-55 tractor and can dig holes with a diameter of 800 mm and a depth of 1,000 mm. The IW-0.7 fruit tree digging machine is used with the Shenniu-25 tractor. If the suspension device is improved, it can be matched with Tie Niu-55 and Shanghai-50 tractors. The machine is equipped with 300, 500, 700 mm three kinds of excavation heads. The digging hole can reach a diameter of 300-700 mm, a depth of 300-700 mm, and 400-500 digging holes per shift. Digging is best done in the first half of the planting period. Excavated topsoil and subsoil are stacked on both sides of the pit, so that they can be exchanged up and down when backfilling. The general depth should not be less than 1 meter. In areas with poor soil quality, digging large holes plays an extremely important role in soil improvement. The orchard's overall layout should be taken into account when orchards are deployed. In particular, the arrangement of strains and row spacing should be adapted to future mechanical operations. In general, the row spacing should be at least wider than the own tractor to ensure that the tractor can be parked in the future. When planting, put the roots of the seedlings into the holes. The seedlings and the roots are placed in the original direction. Fill the topsoil and gently lift the tree upwards to fill the space between the roots and cover the soil. Practical. After planting, a shallow disk hole is opened around the trees for watering. (b) Ditching machine and orchard top dressing 1. Ditching machine In the management of fruit trees, fertilization is an operation with a large amount of work and high labor intensity. In particular, when applying organic fertilizer, it is necessary to dig a continuous or intermittent groove with a width and depth of about 400 mm at both sides of each fruit tree and deeper and deeper in the root distribution layer. Manual work is very difficult and application of trencher operation. 1KGA-300 Orchard Ditching Machine: This machine mainly meets the requirements of ditching for medium spacing and dwarf dense planting orchards. The working part is a horizontal cone screw type and adopts a tractor hydraulic suspension method. Power is transmitted from the tractor's power output shaft to rotate the working part to complete the trenching operation. The machine is composed of a frame, a soil throwing baffle bracket, a bearing seat assembly, a screw, an adjusting tail wheel assembly, a throwing earth baffle assembly and the like. Spiral rotation completes the trenching operation. The spiral is biased and the tail wheel assembly can be adjusted to adjust the depth of the trench. The soil throwing baffle assembly allows the thrown soil to fall back in the vicinity of the fertilizer ditch for easy burial. 2. Several kinds of orchard fertilization method (1) The general garden general method: The fertilizer is applied to the surface of the orchard first, and then the fertilizer is turned into the deep layer in combination with an orchard ploughing, autumn hoeing or winter deep cultivating (about 25 cm). This method is mainly used for the large-scale fertilization of mature orchards or densely planted orchards in the roots of Manyuanyuan, and the fertilizer is mainly based on coarse fat. (2) Scorpion Scorpion Casting: This method is similar to the whole garden general method, except that the fertilizer is concentrated in the crown. After fertilization, deep cultivators are also used to turn the fertilizer into the soil. This method is suitable for fertilizing young orchards, and has the advantage of using less fertilizer than the whole garden general method. Generally used in combination with coarse and fine, slow-effect and quick-effect compound fertilizer. (3) Ring fertilization method: According to the breadth of outward extension of the roots of the fruit tree, dig a trench 40 cm deep and 40 cm wide at the outer edge of the tree crown (to prevent the cutting of coarse roots). Then put the well-equipped fertilizer into the ditch and cover it with soil. This method is suitable for adding organic fertilizer to barley orchards, orchard gardens and young orchards with small canopies in winter or early spring. This method can use trencher operations. (4) Radial fertilization method: Take tree shrews as the center and dig out 5 to 10 30 cm wide and 60 cm long ditch. The width and depth of the ditch can be increased with the extension of the ditch, covering the soil after fertilization. This method is suitable for adding basal fertilizer to mature orchards. (5) Acupuncture or injecting fertilization method: Acupuncture is used to dig a few points of a soil depth of 30 to 60 cm around the canopy and dig a hole to apply the fertilizer into the hole. The method of injecting fertilization is to use a digging machine to dig a hole around the crown and it is about 50 cm deep. The well-prepared fertilizer solution is injected into the hole to slowly infiltrate the fertilizer and utilize the root of the fruit tree. The above two methods are applicable to orchards and densely planted orchards in arid regions, and are mainly based on liquid fertilizers. Point cast can replace ring fertilization. (in the absence of a trencher) but the number of digging holes is sufficient. (6) Groove fertilization method: In the orchard, follow the direction of the fruit trees. Open one deep groove with a width of 40-50 cm in each row, and apply the fertilizer into the ditch and cover the soil. This method is suitable for more orchard orchards and uses mechanized operations. Open the ditch azimuth can press "#" line, according to the vertical and horizontal direction to select one direction every year. The above methods of fertilization have their own characteristics, and they must be selected due to location, time, reason, and fat. The basal fertilizer is applied deeply, superficial dressing is applied lightly, and water is applied immediately after application. (3) Orchard cultivator 3ZG-20 Orchard cultivator with telescopic amplitude modulation. Supports 18-kW wheeled tractors for suspension operations. It is suitable for loose soil and weeding operations in soil tillage areas with low tiller and fruit branch distribution and large canopy trees. 1. Structural Features The machine is composed of two parts, the rack fixing frame and the movable frame. The hydraulic system controls the retractable movable frames on both sides of the implement. When cultivating under the tree with the larger tree crown, the movable frame extends to both sides to maximize the work under the fruit trees. The shelf may not extend when working between rows. In the back of the cultivator spade shovel is equipped with hoe rakes, which can rake the weeds on the soil surface after cultivating till the ground and smooth the surface. The main technical parameters Dimensions (length, breadth and height) 11002000 (3000) 2010 mm Structural quality 366 kg Frame adjustment width 2000 to 3000 mm Soil working parts Chisel loosening spade, spade shovel 10 pieces of soil Workpieces 2 Working depth 50 to 130 mm minimum transport clearance >400 mm working speed 5 to 6 km/h Productivity 0.5 hectares/hour The production use shows that this machine can cut off except for the sturdy grass, and the average weeding rate reaches 96%. Slurry is generally around 90%. 2.19 kilograms of hectares of fuel. Orchard cutting can also use 9C-2 mower. This machine is suitable for cutting grass between rows. The use of a pre-rotation knife, supporting an 18-kW tractor, with a cutting width of 2 meters, can cut 0.66 hectares per hour.
