Description

Technical Field

[0001] The invention relates to the technical field of orchard soil improvement devices, and in particular to a local soil improvement device for an orchard. Background Art

[0002] Soil improvement mainly refers to the action of improving soil through physical, chemical or microbial means.

[0003] There are two traditional ways to improve soil with organic fertilizers. One is to spread organic fertilizers on the ground of the orchard first, and then use a rotary tiller to mix the organic fertilizers with the soil for improvement. In this way, the depth of organic fertilizer application is often very shallow. In fact, it mainly plays the role of shallow fertilization of the orchard soil. It is difficult to have a significant improvement effect on the orchard, and a large amount of organic fertilizers need to be applied. This method is more suitable for soil improvement in the field. The second is trenching fertilization improvement. There are two types of trenching fertilization improvement. One is trenching, then spreading organic fertilizers in the trench, and finally filling it; the other is trenching, then spreading organic fertilizers in the trench, and then mixing organic fertilizers with the soil through the rotary cutter head of the trenching machine, and finally filling it. The first trenching fertilization improvement method requires too much organic fertilizer for the orchard. If the amount of organic fertilizer is small, it is impossible to concentrate on regional soil improvement. It does not have the function of mixing organic fertilizers and soil. In addition, the mechanical device currently used for trenching fertilization improvement will shear the roots of fruit trees between rows on a large scale during the trenching process, which is quite damaging to the roots of fruit trees. The second type of fertilization improvement mechanical device can make up for the function of mixing organic fertilizer and soil that the first type of machinery does not have, but the mixing of organic fertilizer and soil is uneven, and it is not easy to control the reasonable ratio of soil and organic fertilizer. At the same time, this type of fertilization improvement mechanical device will also shear a large area of ​​the roots of fruit trees between rows, causing relatively serious damage to the roots of fruit trees.

[0091] Method of use of the present invention:

[0092] S1, pouring the easily flowing organic fertilizer (such as relatively dry earthworm castings) for soil improvement into the improvement material hopper 30;

[0093] S2, the present invention is opened between the fruit tree rows until the soil drill 20 is basically located directly above the position where the soil is to be improved;

[0094] S3, the staff holds the controller 90 and stands at the side of the present invention. After ensuring that there is no abnormality in the device, first press the main switch 91, and then press the control buttons 92 on the controller 90 in ascending order. Specifically, first press the number 1 key in the control button 92 area, and then press the number 2 key after the component corresponding to the number 1 key completes the action, and then press the number 3 key after the component corresponding to the number 2 key completes the action. In this way, press all the numbers in the control button 92 area to complete the soil improvement operation at one position. In the above manner, the soil improvement task at the rest of the orchard can be completed.

[0095] Press the control buttons 92 on the controller 90 in order from small to large numbers and the corresponding execution actions are as follows:

[0096] After pressing the number key 1, the reduction motor 41 rotates the set angle (according to the selected parameters of the star discharger 40 and the amount of pre-placed organic fertilizer) to place a certain amount of earthworm manure 8 and other organic fertilizers into the drum. Obviously, the number key 1 is the switch of the reduction motor 41, which realizes the start and stop operation of the reduction motor 41.

[0097] After pressing the number key 2, the electric winch 3 rotates clockwise at a set angle to release the wire rope 2, and the worm output head motor 26 rotates clockwise at a set angle to drive the drill rod to drill (the release amount of the wire rope 2 is based on the connection disk 21 approaching or touching the ground, and the worm output head motor 26 rotates clockwise at an angle, and the worm output head motor 26 stops when the connection disk 21 approaches or touches the ground). Obviously, the number key 2 can be replaced by a switch for controlling the forward, reverse and stop of the electric winch 3 (forward and reverse stop switch) and a switch for controlling the forward, reverse and stop of the worm output head motor 26, that is, when operating this step, first turn on the forward gear of the two forward and reverse stop switches controlling the electric winch 3 and the worm output head motor 26, and switch to the stop gear when the connection disk 21 approaches or touches the ground. According to this function, ordinary technicians in the electrical related fields can realize that one control key controls two motors to rotate clockwise at the same time according to the above principle.

[0098] After pressing the number key 3, the electric winch 3 rotates counterclockwise at a set angle to pull up the steel wire rope 2 until the lower end of the earth-drilling device 20 is higher than the drum 50 as a reference height, preferably close to the drum 50 but not in contact with it. Obviously, when the number key 2 is replaced by two independent forward and reverse stop switches for controlling the electric winch 3 and the worm output head motor 26, the function of the number key 3 can be achieved by switching the forward and reverse stop switch for controlling the electric winch 3 to the reverse gear, and when the lower end of the earth-drilling device 20 is higher than the drum 50, switching the forward and reverse stop switch for controlling the electric winch 3 to the stop gear.

[0099] After pressing the number key 4, the second telescopic motor 71 extends to push the roller 50 to the right below the drilling and earth-collecting device 20. Obviously, the number key 4 is the forward stop switch of the second telescopic motor 71.

[0100] After pressing the number key 5, the worm output head motor 26 rotates counterclockwise to unload the soil on the drilling pit soil extractor 20 into the drum 50. The forward and reverse stop switch of the control worm output head motor 26 described in the number key 2 is switched to the reverse gear position to achieve.

[0101] After pressing the number key 6, the first telescopic motor 62 extends to push the cylinder cover 52 until the sliding cover is on the feeding and unloading port 514 of the cylinder 51 and then retracts.
