[0013] As a further improvement of the present invention, a sealing gasket capable of being in interference connection with the crushing rod is provided at the avoidance hole of the opening door.

[0014] A land preparation method for land preparation using an ecological garden engineering land preparation device mainly includes the following steps:

[0015] 1) Adjust the height of the rotary tiller, add fertilizer to the hopper, turn on the suction fan, move the device forward. The tooth rake grabs the grass stems on the ground, and the suction fan sucks the grass stems into the crushing cylinder through the inclined conveying cylinder and the horizontal conveying cylinder. While the grass stems are being conveyed through the inclined and horizontal conveying cylinders, they are preliminarily crushed. Then, turn on the crushing knife, which crushes and mixes the fertilizer and the grass stems.

[0016] 2) Insert the rotary tiller into the ground, move forward while rotating, so as to turn over the soil.

[0017] 3) The lifting rod moves up and down continuously. When the lifting rod moves downward, it drives the crushing knife to crush the larger soil clods turned out, and at the same time, the lifting rod drives the turning door to close. When the lifting rod moves upward, the crushing knife leaves the ground, and at the same time, the lifting rod drives the turning door to open. At this time, the crushed and mixed grass stem fertilizer in the crushing cylinder is scattered downward onto the soil through the sieve. And during the process of scattering the fertilizer and grass stems onto the soil, the nozzle sprays water on the fertilizer and grass stems to make them wet.

[0018] 4) The leveling plate levels the soil after fertilizing and turning over at the rear side.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. By setting a crushing cylinder on the frame, a horizontal conveying pipe and an inclined conveying pipe are arranged in front of the crushing cylinder, a tooth rake is arranged at the bottom of the rear side of the inclined conveying cylinder, a crushing knife and a suction fan are arranged in the crushing cylinder, a feeding hopper is arranged above the crushing cylinder, a tipping door is hinged on one side below the crushing cylinder, the lower part of the tipping door is hinged to a crushing rod, a transition cylinder is fixed below the bottom of the crushing cylinder under the tipping door, a door is arranged at the bottom of the transition cylinder, a knife tip is arranged on the crushing rod, crushing sharp knives are arranged on the inner walls of the horizontal conveying cylinder and the inclined conveying cylinder, and the horizontal conveying cylinder is connected to a rotary tiller through a lifting rod and a fixing plate. A flow channel and a nozzle are arranged inside the crushing rod. During land preparation, the frame moves forward. First, the tooth rake at the front side will grab the grass stems from the ground, and then the suction fan will adsorb the grass stems along the inclined conveying cylinder and the horizontal conveying cylinder into the crushing cylinder. Fertilizer can be added from above the feeding hopper. Then the grass stems and fertilizer are crushed and mixed by the crushing knife in the crushing cylinder. During this process, the lifting rod drives the rotary tiller to insert into the ground, and the rotary tiller rotates in the ground to loosen and turn over the hard ground. Since the grass stems have been collected in the crushing cylinder during the forward movement of the frame, the grass stems can be prevented from winding around the rotary tiller, ensuring the rotary tilling effect of the rotary tiller. After tilling, the crushing rod moves up and down continuously. When the crushing rod moves downward, the crushing rod drives the crushing knife to insert into the ground, so as to break the large soil clods after tilling and ensure that the soil quality is uniform and soft. When the crushing rod moves downward, it can drive the tipping door to close the crushing cylinder to prevent the leakage of fertilizer and crushed grass stem material. When the crushing rod moves upward and the crushing knife leaves the ground, the crushing rod can push the tipping door upward. Then the smaller crushed grass stem powder and fertilizer pass through the sieve and sprinkle downward onto the ground, while the larger grass stems and fertilizer remain in the crushing cylinder for further crushing. Thus, during the continuous crushing of the soil clods, the application of fertilizer and crushed grass stem powder can be completed. In addition, during the continuous lifting and lowering of the crushing rod, it can push the tipping door to open and close continuously. During the continuous pushing of the tipping door to rotate, it can also vibrate the crushing cylinder to a certain small extent. This not only makes the feeding of fertilizer and crushed grass stem powder smoother to reduce blockage to a certain extent, but also can change the state of fertilizer and grass stems to a certain extent during the rotation of the tipping door. Moreover, after the tipping door is pushed upward, it is closer to the crushing knife, which is conducive to more uniform and thorough crushing to a certain extent. In addition, during the rotation of the crushing knife, it can also drive the fertilizer and crushed grass stem powder on the tipping door to the side of the sieve, which is conducive to the discharge of fertilizer.In addition to driving the crushing knives to crush the mud blocks and the crushing knives can cooperate with the flipping door to flip, the tips on the crushing rod can also crush and disperse the fertilizer and straw materials that fall into the transition cylinder again. In addition, the flow channels and nozzles on the crushing rod can also spray water onto the fertilizer and straw materials in the transition cylinder, so as to humidify the fertilizer and straw materials, which is conducive to promoting the later fermentation and aging of the fertilizer and straw materials. During the continuous advancement of the vehicle frame, the rear leveling plate levels the ground to a certain extent and can evenly spread the fertilizer and straw materials in the soil.

[0021] In addition, while the horizontal conveying cylinder and the inclined conveying cylinder convey the straw, they can also cut and crush the straw to a certain extent, improving the overall efficiency of the straw. In addition, when it is not necessary to return the straw to the field, the opening door can be closed, so that the transition cylinder is equivalent to a storage barrel and can store the crushed straw, making the use scenario more flexible and convenient.

[0022] In short, during the land preparation process of this device, the straw is collected before plowing, which can not only prevent the straw from winding around the rotary tiller and causing the rotary tiller to fail to play its due role, but also, after collecting the straw, the straw and fertilizer can be centrally crushed at the same time. After the rotary tiller tills the land, while the crushing knives crush the mud blocks, they can continuously spread the crushed fertilizer and straw into the soil. It has strong functionality, a compact structure, and high efficiency. While the straw is utilized for field return, during the crushing process, the fertilizer and straw materials are mixed and then fertilized into the soil, improving the fertilization effect on the soil. That is, through the integration and improvement of the structure, a new land preparation process and flow can be obtained, improving the land preparation effect and simplifying the land preparation process.

[0023] 2. By providing a middle rod in the middle of both the horizontal conveying cylinder and the inclined conveying cylinder, and blades are provided on the middle rod, so that while the horizontal conveying cylinder and the inclined conveying cylinder convey the straw, the straw is further cut and crushed in the middle.

[0024] 3. By providing a leveling plate, the soil can be pushed, making the land flat as a whole. The leveling plate is set as a horizontal plate and a spiral arc plate. When leveling, the horizontal plate is used to push the soil, and the spiral arc plate can push up the raised soil and scatter the soil from the rear.

[0025] 4. By connecting the transition cylinder to the storage tank through a transmission pipe, when it is not necessary to return the straw to the field, the opening door can be closed, and the transition cylinder can temporarily store the straw and transmit the straw into the storage tank for storage.

[0026] 5. By providing a knife wheel that can rotate in the left and right directions at a position connected to the horizontal conveying cylinder in the crushing cylinder, after the grass stems enter the crushing cylinder, the knife wheel first cuts the grass stems in the horizontal direction to a certain extent, thereby improving the subsequent crushing effect of the grass stems.

[0027] 6. By arranging a second cutter head at the rear end of the fixed plate, the land can be loosened again at the rear side of the rotary plow in all directions.

[0028] 7. A sealing gasket that can be interference-connected with the breaker bar is provided at the avoidance hole of the door opening. After the door opening is closed, when the breaker bar moves up and down, the sealing gasket can seal the door opening to a certain extent.

[0029] 8. A land preparation method using an ecological garden engineering land preparation device can collect grass stems, turn the soil with a rotary plow, break up mud blocks and level the soil. At the same time, the grass stems and fertilizers are crushed and mixed before fertilizing the soil. The soil can be fertilized and the grass stems can be used in the field, which is more efficient and improves the overall land preparation effect. In addition, the grass stems can be collected first to avoid entanglement with the rotary plow and ensure the effect of the rotary plow. Then, the grass stems and fertilizers are crushed and mixed and sprinkled with water before being applied to the soil, thereby improving the effect of fertilizer and grass stem use in the field.

The frame 1 is welded by steel plates or steel sections. The front side of the frame 1 is connected to the front wheel 3 through the front support leg 2, and the rear side of the frame 1 is connected to the rear wheel 5 through the rear support leg 4. The front support leg 2 and the rear support leg are both fixed on the frame 1. The front support leg 2 and the rear support leg 4 can be telescopic mechanisms, and the telescopic mechanism is an electric push rod, a hydraulic cylinder, or other simple telescopic adjustable manual adjustment mechanisms commonly used in the prior art. A driving mechanism capable of driving its movement can be provided on the frame 1, such as a driving mechanism of the traveling motor type commonly used in the prior art, or directly hang this device behind a tractor or other agricultural motor vehicles to be driven to move. A crushing cylinder 6 is fixed at a position near the rear side on the frame 1. The crushing cylinder 6 extends horizontally from left to right, and both the left and right sides of the crushing cylinder 6 are fixedly connected to the frame 1. A feeding hopper 7 is provided above the crushing cylinder 6, as Figure 4As shown, on one side below the crushing cylinder 6, there is an opening 43. At the opening 43, a flip door 8 that can be flipped open is hinged. Between the side of the flip door 8 far from the hinge point and the opening 43 of the crushing cylinder 6, there is a deformable screen 42 connected. Below the flip door 8, it is hinged to a liftable crushing rod 13. The crushing rod 13 can be made of steel plate. At the bottom of the crushing rod 13, a crushing knife 9 is fixed, and the crushing knife 9 extends horizontally left and right. When the crushing rod 13 moves up and down, the crushing rod 13 can drive the flip door 8 to open upward or close downward. After the flip door 8 is flipped upward, during the rotation of the crushing knife 37, the end of the crushing knife 37 contacts the flip door 8, so as to better grind and crush the grass stems.

[0043] As Figure 1 and Figure 2 shown, on the frame 1, in front of the crushing cylinder 6, a horizontal conveying cylinder 10 is fixed. In front of the horizontal conveying cylinder 10, an inclined conveying cylinder 11 is fixed. One end of the horizontal conveying cylinder 10 is connected to the crushing cylinder 6, and one end is connected to the inclined conveying cylinder 11. At the bottom rear of the inclined conveying cylinder 11, a rake 12 facing the front is fixed. At the bottom rear of the rake 12, a first cutter head 35 can be provided, and the first cutter head 35 can pull up the grass stems fixed on the ground. In the crushing cylinder 6, a crushing knife 37 is rotatably connected. Specifically, in the crushing cylinder 6, a rotating shaft 40 is rotatably connected. One end of the rotating shaft 40 is connected to a second rotating motor 41 that drives its rotation. The crushing knife 37 is fixed on the rotating shaft 40. In the crushing cylinder 6, a suction fan 14 is also provided. The suction fan 14 can be arranged at the connection port of the crushing cylinder 6 close to the horizontal conveying cylinder 10, and is used to suck the grass stems into the crushing cylinder 6 from the outside.

[0044] As Figure 1 shown, the crushing rod 13 is connected to the bottom of the horizontal conveying cylinder 10 in a liftable manner through a connecting member. For the connecting member, specifically, as Figure 1 , Figure 6 and Figure 8 shown, the connecting member includes at least two sliding rods 32. The upper ends of the sliding rods 32 are fixed to the bottom of the horizontal conveying cylinder 10. On the crushing rod 13, two sliders 33 that are respectively slidably matched with the sliding rods 32 are fixedly connected. And on the sliders 33, a traveling motor 34 that can drive it to slide up and down is provided. Then, the forward and reverse rotation of the traveling motor 34 can drive the sliders 33 to slide up and down, thereby driving the crushing rod 13 to reciprocate up and down.

[0045] In the crushing cylinder 6, at the position connected to the horizontal conveying cylinder 10, a cutter wheel 31 that can rotate in the left - right direction is provided. Then, after the grass stems enter the crushing cylinder 6, the cutter wheel 31 first cuts the grass stems in the horizontal direction to improve the subsequent crushing effect of the grass stems.

[0046] A transition cylinder 15 is fixed to the bottom of the crushing cylinder 6 below the turning door 8. An openable door 16 is provided at the bottom of the transition cylinder 15. For example, the door 16 can be set to two leaves, which are respectively hinged to the transition cylinder 15 and can be locked with a bolt commonly used in the prior art. An avoidance hole for avoiding the crushing rod 13 is provided on the door 16. As Figure 5 shown, a sealing gasket 36 capable of interference connection with the crushing rod 13 is provided at the avoidance hole of the door 16. Then, after the door 16 is closed, during the up and down movement of the crushing rod 13, the sealing gasket 36 can seal the door 16 to a certain extent.

[0047] In addition, as Figure 2 and Figure 4 shown, a plurality of inclined upward cutting tips 17 are fixed on the crushing rod 13 inside the transition cylinder 15. In addition, as Figure 5 shown, a flow channel 23 is provided inside the crushing rod 13, a nozzle 38 communicating with the flow channel 23 is provided on the crushing rod 13, and the flow channel 23 of the crushing rod 13 is connected to a water tank 25 through a hose 24. As Figure 1 shown, a plurality of crushing cutting knives 18 are provided on the inner walls of the horizontal conveying cylinder 10 and the inclined conveying cylinder 11. When conveying the grass stems, the grass stems are crushed simultaneously. In addition, as Figure 1 shown, a middle rod 26 is provided in the middle of both the horizontal conveying cylinder 10 and the inclined conveying cylinder 11, and a blade 27 is provided on the middle rod 26. Thus, while the horizontal conveying cylinder 10 and the inclined conveying cylinder 11 are conveying the grass stems, the grass stems are further cut and crushed in the middle.

[0048] As Figure 1 and Figure 2 shown, the bottom of the crushing cylinder 6 is connected to a fixing plate 20 through two lifting rods 19. A rotary tiller 21 is rotatably provided on the fixing plate 20. A plurality of rotary tillers 21 are provided. As Figure 3 shown, each rotary tiller 21 includes a rotating plate 211, the rotating plate 211 is rotatably connected to the fixing plate 20, a plurality of plowshares 212 are provided at the bottom of the rotating plate 211, a rotating rod 213 is fixed to the upper end of the rotating plate 211, and the upper end of the rotating rod 213 extends out of the fixing plate 20 and is connected to a first rotating motor 214. In addition, a second cutter head 39 inserted into the ground is fixed to the rear end of the fixing plate 20, and the second cutter head 39 can loosen the land again all around the rear side of the rotary tiller 21.

[0049] As Figure 1 and Figure 2 shown, a leveling plate 22 is provided at the rear wheel 5 at the rear side of the vehicle frame 1. As Figure 2As shown, a plurality of the rear wheels 5 are provided. The plurality of rear wheels 5 are rotatably connected to the rear wheel shaft 28, and the rear wheel shaft 28 is fixedly connected to the vehicle frame 1. The rear wheels 5 are made of steel plates and are relatively thin as a whole. During operation, the rear wheels 5 can be inserted into the soft ground. In order to balance the height difference between the front wheels 3 and the rear wheels 5 on the ground, during setting, the bottom height of the front wheels 3 can be made higher than the bottom height of the rear wheels 5. A leveling plate 22 is provided between adjacent rear wheels 5, and the leveling plate 22 includes a horizontal plate 221 and a spiral arc plate 222 fixedly connected together. The horizontal plate 221 is fixed to the bottom of the rear wheel shaft 28, and a ground-inserting leveling harrow 223 is provided at the lower end of the front side of the horizontal plate 221. The structure of the ground-inserting leveling harrow 223 is as Figure 7 shown. By providing the leveling plate 22, the soil can be pushed, so that the land is leveled as a whole. The leveling plate 22 is set as the horizontal plate 221 and the spiral arc plate 222. During leveling, the horizontal plate 221 is used to push the soil, and the spiral arc plate 222 can push up the raised soil and scatter the soil from the rear side.

[0050] In addition, as Figure 1 shown, one side bottom of the transition cylinder 15 is communicated with the storage tank 30 through a transfer pipe 29. The storage tank 30 is fixed on the vehicle frame 1 or the rear support leg 4. Then, when the grass stems do not need to be returned to the field, the opening door 16 can be closed, and the transition cylinder 15 can temporarily store the grass stems and transfer the grass stems into the storage tank 30 for storage.

[0051] The present invention is provided with a crushing cylinder 6 on the vehicle frame 1. A horizontal conveying pipe and an inclined conveying pipe are arranged on the front side of the crushing cylinder 6. A toothed harrow 12 is arranged at the bottom of the rear side of the inclined conveying cylinder 11. A crushing knife 37 and a suction fan 14 are arranged inside the crushing cylinder 6. A feeding hopper 7 is arranged above the crushing cylinder 6. A turning door 8 is hinged on one side below the crushing cylinder 6. The lower part of the turning door 8 is hinged to a crushing rod 13. A transition cylinder 15 is fixed below the bottom of the crushing cylinder 6 under the turning door 8. An opening door 16 is arranged at the bottom of the transition cylinder 15. A knife tip 17 is arranged on the crushing rod 13. Crushing sharp knives 18 are arranged on the inner walls of the horizontal conveying cylinder 10 and the inclined conveying cylinder 11. And the horizontal conveying cylinder 10 is connected to a rotary tiller 21 through a lifting rod 19 and a fixing plate 20. And a flow channel 23 and a nozzle 38 are arranged inside the crushing rod 13. Then during land preparation, the vehicle frame 1 moves forward. First, the toothed harrow 12 at the front side will grab the grass stems from the ground first, and then the suction fan 14 adsorbs the grass stems along the inclined conveying cylinder 11 and the horizontal conveying cylinder 10 into the crushing cylinder 6. Fertilizer can be added from above the feeding hopper 7. Then the grass stems and the fertilizer are crushed and mixed by the crushing knife 37 in the crushing cylinder 6. During this process, the lifting rod 19 drives the rotary tiller 21 to insert into the ground, and the rotary tiller 21 rotates in the ground to loosen and turn over the hard ground. Because during the forward movement of the vehicle frame 1, the grass stems have been collected into the crushing cylinder 6, it is possible to avoid the grass stems being wound around the rotary tiller 21 and ensure the rotary tilling and land turning effect of the rotary tiller 21. After land turning, the crushing rod 13 moves up and down reciprocally continuously. When the crushing rod 13 moves downward, the crushing rod 13 drives the crushing knife 9 to insert into the ground, so as to break the large mud blocks after land turning and ensure the soil quality is uniformly soft. And when the crushing rod 13 moves downward, it can drive the turning door 8 to close the crushing cylinder 6 to prevent the fertilizer and the crushed grass stem material from leaking out. When the crushing rod 13 moves upward to make the crushing knife 9 leave the ground, the crushing rod 13 can push the turning door 8 upward. Then the smaller crushed grass stem powder and fertilizer pass through the sieve 42 and sprinkle downward onto the ground, and the larger grass stems and fertilizer still remain in the crushing cylinder 6 for further crushing. Thus, during the continuous crushing of the mud blocks, the fertilization of the fertilizer and the crushed grass stem powder can be completed. In addition, during the continuous lifting and lowering of the crushing rod, it can push the turning door 8 to open and close continuously. And during the continuous pushing of the turning door 8 to rotate, it can also continuously vibrate the crushing cylinder 6 to a certain small extent. This not only makes the feeding of the fertilizer and the crushed grass stem powder smoother to a certain extent and reduces blockage, but also can change the state of the fertilizer and the grass stems to a certain extent during the turning of the turning door 8. And after the turning door 8 is pushed upward, the turning door 8 is closer to the crushing knife 37, which is all beneficial to the relatively more uniform and thorough crushing to a certain extent. In addition, during the rotation of the crushing knife 37, it can also drive the fertilizer and the crushed grass stem powder on the turning door 8 to one side of the sieve 42, which is beneficial to the pushing out of the fertilizer.In addition, in addition to driving the crushing knife 9 to crush the mud blocks, and the crushing knife 9 can cooperate with the flip door 8 to flip, the tip 17 on the crushing rod 13 can also re-crush and disperse the fertilizer and straw materials that fall into the transition cylinder 15. In addition, the flow channels 23 and the nozzles 38 on the crushing rod 13 can also spray water onto the fertilizer and straw materials in the transition cylinder 15, so as to humidify the fertilizer and straw materials, which is beneficial to promoting the later fermentation and aging of the fertilizer and straw materials. During the continuous forward movement of the vehicle frame 1, the rear leveling plate 22 levels the ground to a certain extent while evenly spreading the fertilizer and straw materials in the soil.

[0052] In addition, while the horizontal conveying cylinder 10 and the inclined conveying cylinder 11 convey the straws, they can simultaneously cut and crush the straws to a certain extent, improving the overall efficiency of the straws. In addition, when it is not necessary to return the straws to the field, the opening door 16 can be closed, so that the transition cylinder 15 is equivalent to a storage barrel, which can store the crushed straws, and the use scenario is more flexible and convenient.

[0053] In short, during the land preparation process of this device, the straws are collected before plowing. This can not only prevent the straws from winding around the rotary tiller 21 and causing the rotary tiller 21 to fail to play its due role, but also after collecting the straws, the straws and fertilizers can be centrally crushed at the same time. And after the rotary tiller 21 tills the land, while the crushing knife 9 crushes the mud blocks, it can continuously spread the crushed fertilizers and straws into the soil. It has strong functionality, a compact structure and high efficiency, enabling the straws to be utilized for field return. At the same time, during the crushing process, the fertilizers and straw materials are mixed and then fertilized into the soil, improving the fertilization effect on the soil. That is, through the integration and improvement of the structure, a new land preparation process and flow can be obtained, improving the land preparation effect and simplifying the land preparation process.

[0054] A land preparation method using an ecological garden engineering land preparation device mainly includes the following steps:

[0055] 1) Adjust the height of the rotary tiller 21, add fertilizer to the feeding hopper 7, turn on the suction fan 14, move this device forward, the tooth rake 12 grabs the straws on the ground, and the suction fan 14 sucks the straws from the inclined conveying cylinder 11 and the horizontal conveying cylinder 10 into the crushing cylinder 6. While the inclined conveying cylinder 11 and the horizontal conveying cylinder 10 convey the straws, the straws are preliminarily crushed, turn on the crushing knife 37, and the crushing knife 37 crushes and mixes the fertilizer and straws;

[0056] 2) The rotary tiller 21 is inserted into the ground, rotates while moving forward, so as to turn over the soil;

[0057] 3) The crushing rod 13 continuously moves up and down. When the crushing rod 13 moves downward, the crushing rod 13 drives the crushing knife 9 to crush the larger turned-out mud blocks. At the same time, the crushing rod 13 drives the turning door 8 to close. When the crushing rod 13 moves upward, the crushing knife 9 leaves the ground, and at the same time, the crushing rod 13 drives the turning door 8 to open. At this time, the crushed and mixed grass stem fertilizer in the crushing cylinder 6 is scattered downward onto the soil through the sieve 42. And during the process of scattering the fertilizer grass stems onto the soil, the nozzle 38 sprays water on the fertilizer grass stems to make the fertilizer and grass stems wet;

[0058] 4) The leveling plate 22 levels the soil after fertilizing and turning the soil over at the rear side.

[0059] By using a land preparation method with an ecological garden engineering land preparation device, while collecting grass stems, tilling the soil with a rotary tiller, crushing mud blocks and leveling, the grass stems and fertilizer are crushed and mixed and then fertilized on the soil, which can fertilize the soil and make the grass stems return to the field for utilization, more efficient, improve the overall land preparation effect. In addition, the grass stems can be collected first to avoid entanglement of the rotary tiller and ensure the effect of the rotary tiller. Then, the grass stems and fertilizer are crushed, mixed and sprinkled with water and then fertilized onto the soil to improve the effect of the fertilizer and grass stems returning to the field for utilization.
