Description

[0002] Fertilizing fruit trees is an important measure to ensure their healthy growth and high yield. In order to promote the effective absorption of fertilizers by the roots of fruit trees, trenching equipment is usually used to dig trenches next to the fruit trees, and then fertilizers are applied to the trenches and covered with soil. The traditional trenching method is to open a linear trench between two adjacent rows of fruit trees. This trenching method is suitable for conventional crops such as corn and potatoes. Since the planting spacing of fruit trees is larger than the planting spacing of conventional crops, if only trenches are opened between two adjacent rows of fruit trees, the distance between the roots of the fruit trees and the trenches is far, which is not conducive to rapid and full absorption of fertilizers. The utility model patent with application number CN202323563450.5 discloses a fertilization device that can fertilize around fruit trees, but the fertilizer can only be concentrated at a few points, which is not conducive to the uniform absorption of fertilizers by the roots of fruit trees, and continuous trenching and continuous fertilization cannot be achieved.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] The orchard trenching and covering machine of the present invention is as follows Figures 1 to 5 As shown, it includes a mobile body 1, and the mobile body 1 can be any of the existing various planting operation vehicles. A rotating platform 2 is provided at the front end of the mobile body 1, and the rotating platform 2 is rotatably mounted on the mobile body 1, and the rotating platform 2 is connected to a rotating drive mechanism 3 that drives the rotating platform 2 to rotate, and the rotating drive mechanism 3 can be a reduction motor, and the reduction motor is connected to the rotating platform 2 through a gear set. A horizontal connecting frame 4 is fixedly provided on the outer wall of the rotating platform 2. When the rotating platform 2 rotates, the connecting frame 4 and the components on the connecting frame 4 can be driven to rotate synchronously, thereby adjusting the angle of the connecting frame 4 and the position of the components on the connecting frame 4. An arc-shaped guide rail 6 is provided at the end of the connecting frame 4, and a moving seat 7 is provided on the guide rail 6. The moving seat 7 is connected to a trenching drive mechanism 8 that drives the moving seat 7 to move along the guide rail 6, and a trenching mechanism and a soil covering mechanism are provided on the lower surface of the moving seat 7. The guide rail 6 is arranged horizontally to play a guiding role. When the moving seat 7 moves along the guide rail 6, the moving track of the moving seat 7 is arc-shaped. Similarly, the moving tracks of the trenching mechanism and the soil covering mechanism are also arc-shaped. Therefore, the trenching assembly can open an arc-shaped trench on the ground.

[0024] When the present invention is used, the mobile body 1 moves between two adjacent rows of fruit trees, the moving track is a straight line, and the mobile body 1 is located in the middle position between two adjacent rows of fruit trees. When the front end of the mobile body 1 approaches the fruit tree, the rotating driving mechanism 3 is used to drive the rotating platform 2 to rotate at an appropriate angle, and the rotating platform 2 drives the connecting frame 4 and the guide rail 6, the moving seat 7 and other components on the connecting frame 4 to rotate synchronously, so that the guide rail 6 moves to the vicinity of the fruit tree, and the fruit tree is as close to the center of the arc track 6 as possible, and then the ditching driving mechanism 8 is used to drive the moving seat 7 to move along the guide rail 6, and the ditching mechanism is used to ditch. After fertilization, the soil covering mechanism is used to cover the soil.

[0025] The grooves provided by the present invention are arc-shaped grooves, which are arranged around the fruit trees, and the distances between each part of the arc-shaped groove and the fruit trees are kept consistent, so that more roots can absorb the fertilizer in the arc-shaped grooves. When fertilizing, the fertilizer is evenly put into the grooves, the fertilizer is more dispersed and distributed more evenly, and the roots of the fruit trees can absorb the fertilizer in the grooves more evenly, thereby ensuring the fertilization effect.

[0026] In addition, the present invention sets a rotating platform 2 and a connecting frame 4, and installs trenching facilities such as a guide rail 6 on the connecting frame 4. When adjusting the position of the guide rail 6, the rotating platform 2 is used for adjustment, and there is no need to move the mobile body 1 as a whole. The position of the main body of the mobile body 1 can be kept fixed, and the operation is more flexible and convenient.

[0027] Each time when digging trenches and applying fertilizer, fertilizer can be applied on one side of the fruit tree. If fertilizer is to be applied on both sides of the fruit tree, the mobile vehicle body 1 can be moved to the distance between adjacent fruit trees, and then fertilizer can be applied on the other side of the fruit tree.

[0028] In order to improve the stability of the connecting frame 4, vertical reinforcement piles can be set on the connecting frame 4, and the upper end of the reinforcement pile is connected to a power device such as a hydraulic cylinder that drives the reinforcement pile into and out of the ground. When digging trenches, the reinforcement piles can be driven into the ground to keep the connecting frame 4 stable; after fertilization is completed, the reinforcement piles can be pulled out.

[0029] The guide rail 6 includes an arc-shaped inner rail 61 and an arc-shaped outer rail 62. Both the inner rail 61 and the outer rail 62 are in the shape of circular arcs. The inner rail 61 is located inside the outer rail 62, and there is an appropriate distance between the inner rail 61 and the outer rail 62. A first slide groove is provided on the side wall of the inner rail 61 facing the outer rail 62, and a second slide groove is provided on the side wall of the outer rail 62 facing the inner rail 61. The two side edges of the movable seat 7 are respectively located in the first slide groove and the second slide groove, and the movable seat 7 can slide along the first slide groove and the second slide groove. The ditching drive mechanism 8 includes a first motor, which is vertically arranged on the movable seat 7, and a gear 9 is arranged on the main shaft of the first motor. A rack 10 is provided on the side wall of the inner rail 61 or the outer rail 62, and the rack 10 is also in the shape of circular arcs, and the gear 9 meshes with the rack 10. When the first motor is running, it drives the gear 9 to rotate. Since the gear 9 is meshed with the rack 10, under the action of the rack 10, the gear 9 will move along the rack 10, thereby driving the entire moving seat 7 to move in an arc along the inner rail 61 and the outer rail 62.

[0030] In the present invention, the trenching mechanism includes a positioning cylinder 5 arranged on the lower surface of the moving seat 7, a lifting arm 11 is arranged in the positioning cylinder 5 and is slidably matched with the positioning cylinder 5, the upper end of the lifting arm 11 is connected to the first lifting mechanism 12, and the lower end of the lifting arm 11 is connected to the trenching assembly. The first lifting mechanism 12 is used to adjust the height of the trenching assembly. When the mobile body 1 is moving, the trenching assembly is located above the ground, and trenching operation is not performed at this time. When the trenching position is reached, the first lifting mechanism 12 pushes the lifting arm 11 to move downward and provides downward pressure so that the trenching assembly contacts the ground and extends into the soil. The depth of the trenching assembly entering the soil can be adjusted by the first lifting mechanism 12. The first lifting mechanism 12 can adopt equipment such as a hydraulic cylinder.

[0031] At present, there are many trenching components with various functions, and the present invention can adopt any existing trenching components. In orchard management, it is necessary not only to prune the branches of fruit trees, but also to prune the root systems of fruit trees. Pruning the root systems of fruit trees can promote the sprouting of new roots of fruit trees. The new roots have a stronger ability to absorb water and nutrients, which is conducive to the growth of fruit trees. In addition, after the diseased roots and rotten roots are pruned, the risk of disease transmission can be reduced. The existing trenching, fertilization, and soil covering do not have the function of pruning the root systems of fruit trees. When the trenching components encounter the root systems of fruit trees, they cannot quickly cut off the root systems, which affects the trenching efficiency. At the same time, the trenching components are easy to pull the root systems of fruit trees, causing large-area damage to the root systems.

[0032] In order to facilitate cutting off the root system while trenching and prevent the root system from being pulled and damaged in a large area, the trenching assembly of the present invention includes a second motor 13, the second motor 13 is connected to a rotating shaft 14, the rotating shaft 14 is rotatably mounted on the lifting arm 11, and the outer wall of the rotating shaft 14 is provided with a plurality of trenching knives 16 through a mounting ring frame 15. The trenching knives 16 are rectangular, and the plurality of trenching knives 16 are evenly distributed around the rotating shaft 14. The length direction of the trenching knives 16 is consistent with the axial direction of the rotating shaft 14, and the width direction of the trenching knives deviates from the radial direction of the rotating shaft 14. When the rotating shaft 14 drives each trenching knife 16 to rotate, the trenching knife 16 can quickly penetrate into the soil, and when the trenching knife 16 contacts the roots of the fruit tree, the roots can be cut off. The distance between the trenching knife 16 and the rotating shaft 14 gradually decreases from top to bottom, and each trenching knife 16 forms a knife group with a small lower end and a large upper end, which can reduce the resistance to entering the soil. The lower end of the trenching knife 16 and the side away from the rotating shaft 14 are provided with blades to reduce trenching resistance and facilitate cutting roots. The lower end of the trenching knife 16 extends to below the lower end of the rotating shaft 14. The upper end of the positioning cylinder 5 is hinged to the movable seat 7, and an inclined telescopic mechanism 17 is provided between the positioning cylinder 5 and the movable seat 7. The telescopic mechanism 17 is located in front of the positioning cylinder 5, and the front and rear directions are referenced to the moving direction of the movable seat 7 during trenching. When trenching, the movable seat 7 moves forward. The telescopic mechanism 17 can adjust the angles of the positioning cylinder 5, the lifting arm 11, the rotating shaft 14 and other components. When trenching, the lifting arm 11, the rotating shaft 14 and the like can be in an inclined state, thereby reducing trenching resistance.

[0033] When trenching, the trenching assembly as a whole moves in an arc around the fruit tree, and the root system of the fruit tree usually grows radially outward from the fruit tree. When the trenching knife 16 rotates under the drive of the rotating shaft 14, the movement trajectory of the outer blade of the trenching knife 16 is difficult to be perpendicular to the length direction of the root system. In particular, when the root system of the fruit tree is thick, the trenching knife 16 is also difficult to quickly cut off the root system. In order to facilitate the control of the underground root distribution, timely discover the thicker root system and quickly cut off the thick root system, the present invention is provided with an ultrasonic detector 30 for detecting the root system of the fruit tree on the lower surface of the mobile seat 7. The ultrasonic detector 30 is located in front of the positioning tube 5. The ultrasonic detector 30 emits high-frequency sound waves (the sound wave frequency is usually more than 20kHz) to the ground. These high-frequency sound waves propagate in the soil. When the sound waves encounter the root system, part of the sound waves are reflected to the ultrasonic detector 30. The ultrasonic detector 30 receives the reflected sound waves and calculates the root system depth and thickness according to the intensity and frequency of the reflected waves. The ultrasonic detector 30 is connected to the controller 31 to transmit the detection results to the controller 31. The left and right side walls of the lifting arm 11 are provided with a second lifting mechanism 32, and a root cutter 33 is provided at the lower end of the second lifting mechanism 32. The length direction of the root cutter 33 is perpendicular to the radial direction of the guide rail 6, and the second lifting mechanism 32 is connected to the controller 31. When the ultrasonic detector 30 detects that there is a thicker root system in front, the second lifting mechanism 32 is controlled to operate, and the second lifting mechanism 32 pushes the root cutter 33 downward into the soil pond and cuts off the root system, so as to prevent the thicker root system from hindering the operation of the trenching assembly, and at the same time ensure that the thicker root system is quickly cut off, the incision is kept flat, and excessive damage to the root system of the fruit tree is avoided.

[0034] In the prior art, fertilization is usually carried out separately, that is, a trenching mechanism is first used to dig trenches, and then a fertilizer mechanism is used to spread fertilizer into the trenches, and finally soil is covered. When this method is used, the trenches opened must be relatively regular so that fertilizer can be smoothly spread into the trench bottom to ensure the depth of fertilization. However, since the excavated soil is easy to fall into the trenches when digging trenches, it is difficult to form regular trenches, especially when fertilizing orchards, the trenching depth is greater, and it is more difficult to obtain regular trenches. In order to reduce the difficulty of trenching, in the present invention, a rotating shaft 14 is used to spread fertilizer into the soil. Specifically, the cross-section of the lifting arm 11 is concave, and the cross-section of the positioning cylinder 5 is rectangular. Two mounting sleeves 18 are fixedly provided at the lower part of the lifting arm 11. The mounting sleeves 18 are circular sleeves. The rotating shaft 14 is rotatably mounted on the mounting sleeves 18. The second motor 13 is arranged on the outer wall of the lifting arm 11 and is connected to the rotating shaft 14 through a belt. The upper end of the mounting sleeve 18 located above is connected to the fertilizer supply mechanism 22 through the delivery hose 21. The fertilizer supply mechanism 22 is used to store fertilizer and can transfer the fertilizer to the delivery hose 21 at a uniform speed. The existing technology can be used. The rotating shaft 14 is provided with a through hole that axially penetrates the rotating shaft 14. The upper end of the rotating shaft 14 is connected to the mounting sleeve 18. A plug 20 is provided in the lower end of the rotating shaft 14. When trenching, soil easily enters the inner hole of the rotating shaft 14, so the plug 20 is used to close the lower end of the rotating shaft 14. The plug 20 is slidably matched with the rotating shaft 14, and the plug 20 is connected to a driving rod 23. The driving rod 23 penetrates the rotating shaft 14 and the mounting sleeve 18 and is connected to a push-pull mechanism 24. There is a gap between the driving rod 23 and the inner wall of the rotating shaft 14 for fertilizer to pass through. The push-pull mechanism 24 can be a cylinder or other equipment. When trenching, the plug 20 closes the lower end of the rotating shaft 14 to prevent soil from entering the rotating shaft 14. When applying fertilizer, the push-pull mechanism 24 pushes the plug 20 downward for a distance, and the plug 20 moves to the bottom of the rotating shaft 14, so that the lower end of the rotating shaft 14 is opened, and the fertilizer can slide down along the inner hole of the rotating shaft 14 into the opened groove.

[0035] When ditching, the rotating shaft 14 and the lifting arm 11 are in an inclined position, and the lower end of the rotating shaft 14 is located in the front and the upper end is located in the rear. Due to soil resistance during ditching, if fertilization is carried out while ditching, the fertilizer is not easy to enter the soil, but the soil will enter the inner hole of the rotating shaft 14. Therefore, the plug 20 is used to close the lower end of the rotating shaft 14, and fertilization is not carried out. After the movable seat 7 moves from one end of the guide rail 6 to the other end, the movable seat 7 is controlled to move in the reverse direction. When the movable seat 7 moves in the reverse direction, the rotating shaft 14 is driven to move in the reverse direction. At this time, the lower end of the rotating shaft 14 is basically not subject to soil resistance. Therefore, the push-pull mechanism 24 can be used to push the plug 20 downward to the bottom of the rotating shaft 14, so that the lower end of the rotating shaft 14 is opened, and then the fertilizer in the fertilizer supply mechanism 22 is transported to the installation sleeve 18 through the conveying hose 21, and then enters the rotating shaft 14 and slides down along the rotating shaft 14 to the bottom of the ditch.

[0036] In the present invention, the soil covering mechanism includes a third lifting mechanism 25, the third lifting mechanism 25 is connected to a soil covering arm 26, and a V-shaped soil covering plate 27 is provided at the lower end of the soil covering arm 26. When trenching, the soil covering plate 27 is located above the ground. When fertilizing, that is, when the movable seat 7 moves in the reverse direction, the third lifting mechanism 25 pushes the soil covering arm 26 to move downward, so that the lower end of the soil covering plate 27 contacts the ground. When the soil covering plate 27 moves, the soil on both sides of the trench can be scraped into the trench to complete the soil covering.

[0037] In order to facilitate the timely discovery and cleaning of rotten and diseased roots of fruit trees, the present invention is provided with an image detection element 28 for detecting rotten and diseased roots of fruit trees on the outer wall of the lower end of the lifting arm 11. The image detection element 28 can be a camera. A display screen 29 is provided on the mobile body 1. The image detection element 28 is connected to the display screen 29. The display screen 29 can display the image collected by the image detection element 28 to facilitate observation of the health status of the root system of the fruit tree.

[0038] The trenching knife 16 is easy to wear. In order to facilitate the replacement of the trenching knife 16, the mounting ring frame 15 includes a positioning sleeve 151. The positioning sleeve 151 is sleeved on the rotating shaft 14 and connected to the rotating shaft 14 by screws. Mounting ring plates 152 are provided at both ends of the positioning sleeve 151. The edge of the mounting ring plate 152 is provided with multiple mounting bevel grooves. The trenching knife 16 is inserted into the mounting bevel groove and connected to the mounting ring plate 152 by screws.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
