Description

Technical Field

[0001] The invention relates to the technical field of fruit tree planting, in particular to a device for returning organic fertilizer to fields by covering orchards with grass and green manure. Background Art

[0002] Soybeans and rapeseed are the best leguminous green manure crops for orchards to improve soil fertility. They have the characteristics of fast growth, high yield, complete nutrients, easy to rot, timely fertilizer supply, etc., and have good effects on improving soil fertility. Soybeans are excellent "summer green manure". After the Grain Rain, they should be planted in dense rows appropriately, and two 40cm driving paths should be left according to the wheel spacing of the sprayer. In order to obtain the economic benefits of intercropping, the straw can be returned to the field after the soybean is harvested, or it can be crushed and returned to the field during the pod-setting period.

[0003] With the development of agricultural machinery marketization, green manure crushing and returning machine has become an important field of agricultural machinery development in my country, so it is necessary to strengthen the research and technological innovation of green manure crushing and returning machine technology.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. In the present application, by arranging a rolling plate, a rolling wheel, a toothed cutter and a stripping wheel, when the device moves forward, green manure forage that exceeds the length will be pushed to both sides by the grass dividing plate and enter into the gap between the rolling plate and the rolling wheel. On the one hand, the scissor-like structure formed by the toothed cutter and the cutter will shear the forage from the bottom, thus avoiding the problem of grass entanglement caused by the flexible stems of leguminous green manure. On the other hand, during the rotation of the rolling wheel, the forage is squeezed between the rolling plate and the rolling wheel, which can crush the seeds on the forage to prevent them from sprouting and robbing the fertility during the process of being used as green manure. At the same time, the loose forage is also pressed into dense grass pieces, and is cut into individual grass pieces by the dividing knife during the rotation of the rolling wheel, and then stripped under the action of the stripping wheel.

[0020] 2. In the present application, a main conveyor belt, an auxiliary conveyor belt, a rotating telescopic rod and a grass shredder are arranged, and the speed of the auxiliary conveyor belt is made faster than that of the main conveyor belt, so that a speed difference can be generated between the two. When the grass pieces come into contact with the auxiliary conveyor belt, the grass pieces will be twisted into cylindrical long strips due to the speed difference, and eventually enter the gap of the feed port, fall to the bottom and be chopped by the grass shredder, and then the grass shredder will break up the cut objects and evenly fall on the soil surface below. This process can keep the fiber direction of the green manure grass consistent during the chopping process, and can be cut more finely. After being broken up, it is easier to decompose by spreading it on the soil surface. At the same time, rolling it into strips also avoids the problem of grass entanglement during chopping.

[0021] 3. In the present application, by setting up the soil dividing plate, propulsion teeth and soil discharge port, the soil layer will be divided into two parts during the movement of the device. One part passes from front to back on the upper surface of the soil dividing plate, and the other part passes from front to back along the lower end surface of the bottom of the propulsion teeth, and finally reunites at the rear side of the soil discharge port. On the one hand, the movement of the propulsion teeth just cuts off the main root of the forage, and ensures that the soil where the lateral roots are located will be disturbed as little as possible, ensuring the survival of the forage, and effectively solving the problem of forage and fruit trees competing for fertilizer. On the other hand, the fertilizer in the fertilizer box, the cut green manure debris and the decomposed material in the decomposition box can be laid in the soil from top to bottom, which is beneficial to the growth of fruit trees.

[0022] In summary, through the setting of the above-mentioned structure, the present application can effectively harvest green manure without grass entanglement and improve fertilizer utilization rate. While ensuring the survival of green manure and continuing to fix nitrogen, a part of the branches and leaves are returned to the field and the possibility of green manure robbing nutrients needed by fruit trees is reduced, thereby increasing the amount of nutrients that can be absorbed by fruit trees.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] Reference Figures 1 to 15 A device for returning organic fertilizer to the field by covering the orchard with grass and green manure includes an exoskeleton 1. Driven wheels 13 are rotatably installed on both sides of the lower front end of the exoskeleton 1. A fixed plate 12 is fixedly installed below the rear end of the exoskeleton 1. An engine 3 is fixedly installed on the upper surface of the fixed plate 12. A travel module 35 is fixedly installed below the middle position of the exoskeleton 1. The travel module 35 is a prior art, and driving wheels 11 are installed on its left and right ends. When the travel module 35 is running, the driving wheels 11 at both ends can be driven to rotate, thereby driving the device as a whole to move. In order to control the moving direction of the device as a whole, a control handle 5 is also installed at the upper end of the travel module 35. The control handle 5 is a prior art, and its specific structural design is not repeated here.

[0041] An upper partition 2 and a lower partition 20 are fixedly installed in sequence from top to bottom on the upper inner part of the front side of the exoskeleton 1. A first rotating shaft 32 that runs through the upper partition 2 and the lower partition 20 is rotatably installed on one side of the upper partition 2 and the lower partition 20 close to the engine 3. A third rotating shaft 34 is arranged directly below the first rotating shaft 32. The lower end of the third rotating shaft 34 is connected to the internal structure of the traveling module 35. A second rotating shaft 33 is arranged directly in front of the output end of the engine 3. The output end of the engine 3, the first rotating shaft 32, the second rotating shaft 33 and the third rotating shaft 34 are transmitted through the third bevel gear group 31. The third bevel gear group 31 consists of four bevel gears, and the four bevel gears are respectively fixedly installed on the output end of the engine 3, the first rotating shaft 32, the second rotating shaft 33 and the third rotating shaft 34, so that one engine 3 can simultaneously drive multiple rotating shafts to rotate simultaneously.

[0042] The first rotating shaft 32 is driven by a first synchronous belt 24 on the outer side of the top end, and the first synchronous belt 24 is driven by a first transmission shaft 233 on the end away from the first rotating shaft 32. After the first transmission shaft 233 rotates and passes through the upper partition 2 and the lower partition 20, a group of rolling wheels 23 are fixedly installed on it. Another group of rolling wheels 23 is arranged on one side of the rolling wheels 23, and a driven shaft is fixedly installed on the top of the other group of rolling wheels 23. The driven shaft rotates and passes through the lower partition 20. The first transmission shaft 233 and the driven shaft are fixedly sleeved with a first gear 201 on the outer sides of the upper ends, and the two first gears 201 are meshingly connected. The two first gears 201 are meshedly connected with a transmission gear 202 on one side close to the engine 3, a first connecting shaft is rotatably installed inside the transmission gear 202, the top of the first connecting shaft is fixedly connected to the lower end of the upper partition 2, a second gear 203 is meshedly connected to one side of the transmission gear 202, a stripping wheel 26 is arranged directly below the second gear 203, a second connecting shaft is fixedly installed inside the stripping wheel 26, the upper end of the second connecting shaft is rotatably connected to the lower end of the upper partition 2 after passing through the second gear 203, the stripping wheel 26 is a rubber roller, and vertically arranged rubber strips are evenly distributed on its outer wall, and the rubber strips are in contact with the surface of the rolling wheel 23.

[0043] Through the setting of the above structure, the first rotating shaft 32 can drive the first synchronous belt 24 to drive the first transmission shaft 233 to rotate. While the first transmission shaft 233 rotates, it drives a group of rolling wheels 23 and the first gear 201 connected thereto to rotate. Through the meshing connection between the two first gears 201, it can drive another group of rolling wheels 23 to rotate in the opposite direction. While the two first gears 201 rotate, they can drive the peeling wheel 26 to rotate through the transmission gear 202 and the second gear 203.

[0044] There are multiple vertically arranged dividing knives 231 evenly distributed on the surface of the rolling wheel 23, and a circle of tooth cutting knives 232 are fixedly installed at the lower end of the rolling wheel 23. Two groups of rolling plates 22 that are symmetrically arranged are fixedly installed on the inner side of the front end of the exoskeleton 1, and the rolling wheel 23 is located between the two groups of rolling plates 22. A cutting knife 221 is fixedly installed below the side of the rolling plate 22 close to the rolling wheel 23. The cutting knife 221 is close to the tooth cutting knife 232, and the gap between the rolling wheel 23 and the rolling plate 22 gradually decreases from front to back. In order to allow green manure forage to smoothly enter the gap between the rolling wheel 23 and the rolling plate 22 during the movement of the device, a grass dividing plate 21 fixedly installed on the lower surface of the lower partition 20 is provided at the middle position of the front end of the two groups of rolling wheels 23. The grass dividing plate 21 is set in a cone.

[0045] The outer side of the upper end of the first transmission shaft 233 is driven by a second synchronous belt 25, and the end of the second synchronous belt 25 away from the first transmission shaft 233 is driven by a second transmission shaft 250, the lower end of the second transmission shaft 250 rotates and penetrates the upper partition 2, and a transverse transmission shaft 252 is rotatably installed on the upper end surface of the lower partition 20, and fourth gears 205 are arranged below the left and right sides of the transverse transmission shaft 252. The end of the transverse transmission shaft 252 close to the second transmission shaft 250 is connected to the second transmission shaft 250 and the fourth gear 205 through the first bevel gear set 251, and the end of the transverse transmission shaft 252 away from the second transmission shaft 250 is connected to the second transmission shaft 250 through the second bevel gear set 253. The fourth gear 205 on this side is connected for transmission, and one side of the fourth gear 205 is meshedly connected with the third gear 204. The lower end of the fourth gear 205 is driven by the main conveyor belt 27 after rotating and passing through the lower compartment 20, and the lower end of the third gear 204 is driven by the auxiliary conveyor belt 28 after rotating and passing through the lower compartment 20. Both the main conveyor belt 27 and the auxiliary conveyor belt 28 extend to one side of the stripping wheel 26, so that the grass pieces pressed by the rolling wheel 23 and the rolling plate 22 are driven between the main conveyor belt 27 and the auxiliary conveyor belt 28 under the action of the stripping wheel 26 after being stripped by the stripping wheel 26, and are transported backward under the action of the main conveyor belt 27 and the auxiliary conveyor belt 28.

[0046] Electric push rods 4 are fixedly installed on both sides of the left and right sides of the middle section of the exoskeleton 1. The output end of the electric push rod 4 faces downward and is fixedly installed with a side plate 43. A soil dividing plate 44 is fixedly installed between the two sets of side plates 43. The soil dividing plate 44 is arranged in an arc shape, and a propulsion tooth 441 is fixedly installed at its front end, and a soil discharge port 444 is fixedly installed at the rear end. During the forward movement of the device, the soil layer will be divided into two parts under the action of the propulsion tooth 441 and the soil dividing plate 44. One part passes from the upper surface of the soil dividing plate 44 from front to back, and the other part passes from front to back along the bottom end surface of the propulsion tooth 441, and finally reunites at the rear side of the soil discharge port 444.

[0047] Two symmetrically arranged feed ports 442 are fixedly installed on the left and right sides of the upper end of the dividing plate 44. The feed ports 442 are connected to the bottom of the dividing plate 44. Each feed port 442 is located behind the adjacent main conveyor belt 27 and auxiliary conveyor belt 28, so that the grass pieces transported by the main conveyor belt 27 and the auxiliary conveyor belt 28 can enter the corresponding feed port 442 and fall under the dividing plate 44 through the feed port 442. In order to chop the grass pieces during the falling process, a gearbox 331 is connected to the front end of the second rotating shaft 33. The output end of the gearbox 331 faces downward and is equipped with a rotating telescopic rod 332. After the lower end of the rotating telescopic rod 332 rotates and passes through the soil dividing plate 44, multiple groups of grass breaking knives 333 and multiple groups of breaking rods 334 are fixedly installed in sequence. When the grass pieces pass through the grass breaking knives 333 and the breaking rods 334, they can be fully crushed and scattered by the two. At the same time, in order to prevent the telescopic rod from disturbing the soil layer on the upper end surface of the soil dividing plate 44 during the rotation process, a protective cover 443 is fixedly installed on the upper end surface of the soil dividing plate 44, and the protective cover 443 is rotatably sleeved on the outer side of the rotating telescopic rod 332.

[0048] A fertilizer box 41 is fixedly installed on one side of the middle section of the exoskeleton 1, and a decomposition box 42 is fixedly installed on the other side. Feeding ports are arranged at the upper ends of the fertilizer box 41 and the decomposition box 42. The lower end of the fertilizer box 41 is connected with a fertilizer pipe 411, and the lower end of the decomposition box 42 is connected with a decomposition pipe 421. The lower end of the fertilizer pipe 411 is connected with a fertilizer spraying pipe 412 fixedly installed in front of the lower end of the dividing plate 44 and arranged horizontally after passing through the dividing plate 44. The lower end of the decomposition pipe 421 is connected with a material spraying pipe 422 fixedly installed behind the lower end of the dividing plate 44 and arranged horizontally after passing through the dividing plate 44. A plurality of discharge ports are evenly spaced at the lower ends of the fertilizer spraying pipe 412 and the material spraying pipe 422.

[0049] The specific working principle of the present invention is as follows: when the device moves forward, the green manure grass that exceeds the length will be pushed to both sides by the grass dividing plate 21 and enter the gap between the rolling plate 22 and the rolling wheel 23. In the process of the device moving forward, the gap between the rolling plate 22 and the rolling wheel 23 gradually narrows from front to back, and the grass will be clamped by the rolling plate 22 and the rolling wheel 23. At this time, the scissor-like structure formed by the toothed cutter 232 and the cutter 221 will shear the grass from the bottom, thus avoiding the problem of grass entanglement caused by the flexible stems of leguminous green manure. During the rotation of the rolling wheel 23, the grass is squeezed between the rolling plate 22 and the rolling wheel 23, which can crush the seeds on the grass to prevent them from germinating and robbing the fertility during the process of being used as green manure. As the gap gradually narrows, the loose grass is also pressed into dense grass pieces, and is cut into individual grass pieces by the dividing knife 231 as the rolling wheel 23 rotates. The stripping wheel 26 is a rubber roller with uniform rubber strips on the side walls. These rubber strips are tightly attached to the rolling wheel 23, and will strip the grass pieces pressed by the rolling wheel 23 and the rolling plate 22, and drive them to the surface of the main conveyor belt 27. The main conveyor belt 27 will drive the grass pieces backward, and the other side of the grass pieces will contact the auxiliary conveyor belt 28 during the process. Since the diameter of the third gear 204 is smaller than the diameter of the fourth gear 205, the angular velocity of the third gear 204 after meshing will be greater than that of the fourth gear 205, and The main conveyor belt 27 is driven by the fourth gear 205, and the auxiliary conveyor belt 28 is driven by the third gear 204. Therefore, the speed of the auxiliary conveyor belt 28 will be faster than that of the main conveyor belt 27, and there will be a speed difference between the two. As a result, after the grass pieces come into contact with the auxiliary conveyor belt 28, the grass pieces will be twisted into cylindrical strips due to the speed difference, and eventually enter the gap of the feed port 442, fall to the bottom and be chopped by the grass shredder 333, and then the grass shredder 333 will break up the cut objects and evenly fall on the soil surface below. This process can keep the fiber direction of the green manure grass consistent during the chopping process, and can be cut more finely. After being broken up, it is easier to decompose by spreading it on the soil surface. At the same time, rolling it into strips also avoids the problem of grass entanglement during chopping.

[0050] During the movement of the device after starting, the electric push rod 4 will start, pushing the side plate 43 to gradually descend, and the propulsion teeth 441 and the soil dividing plate 44 are fixed to the side end surface of the side plate 43. The two movement directions of descent and advance will cause the propulsion teeth 441 to obliquely cut into the soil layer until the electric push rod 4 stops advancing after reaching the specified depth. The propulsion teeth 441 and the soil dividing plate 44 will change to horizontal movement along the travel direction. At this time, the device can be driven to the area where weeding and fertilization are required for fertilization operations. When the soil layer moves forward, it will be divided into two parts during the movement. One part passes from the upper surface of the soil dividing plate 44 from front to back, and the other part passes from front to back along the bottom end surface of the pushing tooth 441, and finally reunites at the back of the soil discharge port 444. The space between the lower end surface of the soil dividing plate 44 and the lower end surface of the pushing tooth 441 will form a soil-free area. During the movement, a small amount of soil that enters from the bottom and is higher than the lower end surface of the pushing tooth 441 will be discharged from the soil discharge port 444, ensuring that the soil-free area will not be flooded due to the continuous inflow of soil. The soil layers are separated because in the process of returning green manure to the field in the orchard, the roots of the green manure forage need to perform nitrogen fixation and other operations, so it is necessary to ensure the survival of the forage while not competing with the fruit trees for too much nutrients. The main root of the grass is usually more than one meter deep, and the lateral roots are usually distributed in a 20-centimeter thick soil layer. Therefore, as long as the main root is cut off and fertilization is carried out below the 20-centimeter soil layer, the problem of grass and fruit trees competing for fertilizer can be effectively solved. At the same time, after the main root is cut off, the apical dominance will promote the growth of the lateral roots of the grass, making the grass root coverage denser, thereby further improving the nitrogen fixation ability of the root system. The advancing process of the thruster 441 just cuts off the main root of the grass, and ensures that the soil where the lateral roots are located will be disturbed as little as possible, ensuring the survival of the grass. The soilless space formed under the soil dividing plate 44 is fertilized by the device, and fertilization is carried out just below the grass root system after cutting. There are two partitions below the soil dividing plate 44 to divide the soilless space into three sections. During the movement, the fertilizer in the fertilizer box 41 will enter the fertilizer spraying pipe 412 from the fertilizer pipe 411 and be evenly sprayed on the surface in front of the bottom of the soil dividing plate 44. The middle section will be covered with cut green manure debris, and the decomposed material in the decomposition box 42 will enter the spraying pipe 422 from the decomposition pipe 421 and be evenly sprayed on the surface of the paved green manure debris layer, completing the fertilization operation of the green manure and the preparation for natural decomposition. The shield 443 is sleeved on the surface of the rotating telescopic rod 332 to prevent the rotating telescopic rod 332 from rotating and disturbing the soil layer on the upper end surface of the soil dividing plate 44. When the main root of the grass is cut off, it cannot absorb the nutrients below, and the green manure below is gradually decomposed under the action of the decomposed material and becomes nutrients that can be absorbed by the orchard. During daily watering, it penetrates downward with water into the root layer of the fruit trees, effectively reducing the situation where the green manure competes with the fruit trees for fertilizer.
