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

[0014] A land preparation method using an ecological garden engineering land preparation device for land preparation mainly includes the following steps: 1) Adjust the height of the rotary tillage plow, add fertilizer to the hopper, turn on the suction fan, move the device forward, the tooth rake grabs the grass stems on the ground, the suction fan sucks the grass stems from the inclined conveying cylinder and the horizontal conveying cylinder into the crushing cylinder, and the grass stems are initially crushed while the inclined conveying cylinder and the horizontal conveying cylinder are conveying the grass stems. Turn on the crushing knife, and the crushing knife crushes and mixes the fertilizer and grass stems; 2) The rotary tiller is inserted into the ground, moving forward and rotating to turn the soil; 3) The lifting rod moves up and down continuously. When the lifting rod moves downward, the lifting rod drives the crushing knife to crush the larger mud blocks that are turned out, and at the same time, the lifting rod drives the flip 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 flip door to open. At this time, the crushed and mixed grass stem fertilizer in the crushing cylinder is sprinkled down into the soil through the screen. In the process of the fertilizer grass stems being sprinkled into the soil, the nozzle sprinkles water on the fertilizer grass stems to make the fertilizer and grass stems wet; 4) The leveling plate is used to level the soil after fertilization and tillage at the rear side.

[0015] Compared with the prior art, the present invention has the following advantages: 1. A crushing cylinder is arranged on the frame, a horizontal conveying pipe and an inclined conveying pipe are arranged on the front side of the crushing cylinder, a toothed rake is arranged on 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 flip door is hinged on one side of the lower side of the crushing cylinder, the lower side of the flip door is hinged with a breaking rod, a transition cylinder is fixed below the flip door at the bottom of the crushing cylinder, an opening door is arranged at the bottom of the transition cylinder, a knife tip is arranged on the breaking rod, crushing 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 the rotary plow through a lifting rod and a fixing plate, and a flow channel and a flow nozzle are arranged inside the breaking rod. When leveling the land, the frame moves forward, and the toothed rake at the front side is first The grass stems will be grabbed from the ground first, and then the suction fan will absorb the grass stems into the crushing cylinder along the inclined conveying cylinder and the horizontal conveying cylinder, and fertilizer can be added from the top of the feeding hopper, and the grass stems and fertilizer will be crushed and mixed by the crushing knife in the crushing cylinder. In this process, the lifting rod drives the rotary plow to be inserted into the ground, and the rotary plow rotates in the ground to loosen and turn the hard ground. Because the grass stems have been collected in the crushing cylinder during the forward movement of the frame, it can avoid the grass stems from being entangled in the rotary plow, ensuring the rotary tillage and turning effect of the rotary plow; and after turning the ground, the breaking rod keeps moving up and down, and when the breaking rod moves downward , the breaker bar drives the breaker knife to insert into the ground, so that the large mud blocks after turning the soil can be broken, ensuring that the soil is uniform and soft, and when the breaker bar moves downward, it can drive the flip door to close the crushing barrel to prevent the fertilizer and grass stem crushed materials from leaking out; when the breaker bar moves upward to make the breaker knife leave the ground, the breaker bar can push the flip door upward, and the broken smaller grass stem powder and fertilizer will be sprinkled down to the ground through the screen, and the larger grass stems and fertilizers will remain in the crushing barrel for crushing, so that the fertilizer and grass stem powder can be applied in the process of continuously breaking the mud blocks; in addition, in the process of continuous lifting of the breaker bar, In order to push the flip door to open and close continuously, and in the process of continuously pushing the flip door to rotate, the crushing barrel can also be continuously vibrated to a certain extent, which not only makes the feeding of fertilizer and grass stem powder more comfortable to a certain extent and reduces blockage, but also in the process of flipping the flip door, it can also make certain changes to the state of fertilizer and grass stem. After the flip door is pushed upward, the flip door is closer to the crushing knife, which is conducive to relatively more uniform and thorough crushing to a certain extent. In addition, during the rotation of the crushing knife, the fertilizer and grass stem powder on the flip door can also be driven to one side of the screen, which is conducive to the push out of the fertilizer.In addition, in addition to driving the crushing knife to crush the mud blocks and the crushing knife can be turned over in conjunction with the turning door, the tip of the knife on the crushing rod can also crush and scatter the fertilizer and grass stem material that falls into the transition tube again. In addition, the flow channel and flow nozzle on the crushing rod can also spray water onto the fertilizer and grass stem material in the transition tube, so as to humidify the fertilizer and grass stem material, which is beneficial to promote the fermentation and fermentation of the fertilizer and grass stem material in the later stage. While the frame continues to move forward, the screed plate on the rear side can level the ground to a certain extent and spread the fertilizer and grass stem material evenly in the soil.

[0016] In addition, when the horizontal conveyor cylinder and the inclined conveyor cylinder are conveying grass stems, the grass stems can be cut and crushed to a certain extent at the same time, thereby improving the overall efficiency of the grass stems. In addition, when the grass stems do not need to be turned over, the door can be closed, so that the transition cylinder is equivalent to a storage barrel, which can store the crushed grass stems, and the use scenario is more flexible and convenient.

[0017] In short, during the land preparation process, the device collects grass stems before turning the soil, which not only prevents the grass stems from being entangled in the rotary plow and causing the rotary plow to be unable to play its role, but also after the grass stems are collected, the grass stems and fertilizers can be centrally crushed at the same time. After the rotary plow is plowed, the crushing knife can continuously spread the crushed fertilizers and grass stems into the soil while crushing the mud blocks. It has strong functionality, compact structure, and improved efficiency, so that the grass stems can be used in the field. In the process of crushing, the fertilizer and grass stem materials are mixed and then applied to the soil, which improves the fertilization effect on the soil. That is, through structural integration and improvement, a new land preparation technology and process can be obtained, the land preparation effect is improved, and the land preparation process is simplified.

[0018] 2. A middle rod is provided in the middle of the horizontal conveying cylinder and the inclined conveying cylinder, and a blade is provided on the middle rod, so that the grass stems can be further cut and crushed in the middle while the horizontal conveying cylinder and the inclined conveying cylinder are conveying the grass stems.

[0019] 3. By setting up a leveling plate, the soil can be pushed to make the land flat as a whole. The leveling plate is set to 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 back side.

[0020] 4. By connecting the transition tube to the storage box through the transmission pipe, when the grass stems are not needed to be returned to the field, the door can be closed, the transition tube can temporarily store the grass stems, and the grass stems can be transmitted to the storage box for storage.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0036] In addition, if Figure 1 As shown, the bottom of one side of the transition tube 15 is connected to the storage box 30 through the transmission pipe 29. The storage box 30 is fixed on the frame 1 or the rear leg 4. When the grass stems are not needed to be turned over to the field, the door 16 can be closed, and the transition tube 15 can temporarily store the grass stems and transmit the grass stems to the storage box 30 for storage.

[0037] The present invention comprises the following steps: a crushing cylinder 6 is arranged on a frame 1, a horizontal conveying pipe and an inclined conveying pipe are arranged on the front side of the crushing cylinder 6, a toothed rake 12 is arranged on the bottom of the rear side of the inclined conveying cylinder 11, a crushing knife 37 and a suction fan 14 are arranged in the crushing cylinder 6, a feeding hopper 7 is arranged above the crushing cylinder 6, a flip door 8 is hingedly connected to one side of the lower side of the crushing cylinder 6, and a crushing rod 13 is hingedly connected to the lower side of the flip door 8, a transition cylinder 15 is fixed to the lower side of the crushing cylinder 6 below the flip door 8, an opening door 16 is arranged at the lower side of the transition cylinder 15, a knife tip 17 is arranged on the crushing rod 13, a crushing knife 18 is arranged on the inner wall of the horizontal conveying cylinder 10 and the inclined conveying cylinder 11, and the horizontal conveying cylinder 10 is connected to a rotary plow 21 through a lifting rod 19 and a fixing plate 20, and a flow channel 23 and a flow nozzle 3 are arranged inside the crushing rod 13. 8, when tilling the land, the frame 1 moves forward, and the tooth rake 12 at the front side will first grab the grass stems from the ground, and then the suction fan 14 will absorb the grass stems along the inclined conveying cylinder 11 and the horizontal conveying cylinder 10 into the crushing cylinder 6, and fertilizer can be added from above the feeding hopper 7, and the grass stems and fertilizer are crushed and mixed by the crushing knife 37 in the crushing cylinder 6. In this process, the lifting rod 19 drives the rotary plow 21 to be inserted into the ground, and the rotary plow 21 rotates in the ground to loosen and turn the hard ground. Because the grass stems have been collected in the crushing cylinder 6 during the forward movement of the frame 1, it can prevent the grass stems from being entangled in the rotary plow 21, thereby ensuring the rotary tillage and turning effect of the rotary plow 21; and before turning the soil After that, the crushing rod 13 continuously moves up and down reciprocatingly. When the crushing rod 13 moves downward, the crushing rod 13 drives the crushing knife 9 to insert into the ground, so that the large mud blocks after turning over the soil can be crushed to ensure that the soil is uniform and soft, and when the crushing rod 13 moves downward, it can drive the flip door 8 to close the crushing barrel 6 to prevent the fertilizer and grass stem crushed materials from leaking out; and when the crushing rod 13 moves upward to make the crushing knife 9 leave the ground, the crushing rod 13 can push the flip door 8 upward to open, so that the crushed smaller grass stem powder and fertilizer are sprinkled downward to the ground through the screen 42, and the larger grass stems and fertilizers are still left in the crushing barrel 6 for crushing, so that the fertilizer and grass stem powder can be applied in the process of continuously crushing the mud blocks; In the process of continuous lifting of the external crushing rod, the flip door 8 can be pushed to open and close continuously, and in the process of continuously pushing the flip door 8 to rotate, the crushing barrel 6 can also be continuously vibrated to a certain extent, which not only makes the feeding of fertilizer and grass stem powder more comfortable to a certain extent and reduces blockage, but also in the process of flipping the flip door 8, the state of the fertilizer and grass stem can be changed to a certain extent. After the flip door 8 is pushed upward, the flip door 8 is closer to the crushing knife 37, which is conducive to relatively more uniform and thorough crushing to a certain extent. In addition, during the rotation of the crushing knife 37, the fertilizer and grass stem powder on the flip door 8 can also be driven to one side of the screen 42, which is conducive to the push-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 knife tip 17 on the crushing rod 13 can also crush and scatter the fertilizer and grass stem materials that fall into the transition tube 15 again. In addition, the flow channel 23 and the flow nozzle 38 on the crushing rod 13 can also spray water onto the fertilizer and grass stem materials in the transition tube 15, so that the fertilizer and grass stem materials can be humidified, which is beneficial to promote the fermentation and fermentation of the fertilizer and grass stem materials in the later stage. In the process of the frame 1 continuing to move forward, the rear side of the screed plate 22 can evenly spread the fertilizer and grass stem materials in the soil while leveling the ground to a certain extent.

[0038] In addition, when the horizontal conveying cylinder 10 and the inclined conveying cylinder 11 are conveying grass stems, the grass stems can be cut and crushed to a certain extent, thereby improving the overall efficiency of the grass stems. In addition, when the grass stems do not need to be turned over, the door 16 can be closed, so that the transition cylinder 15 is equivalent to a storage barrel, which can store the crushed grass stems, and the use scene is more flexible and convenient.

[0039] In short, during the land preparation process, the device collects the grass stems before turning the soil, which not only prevents the grass stems from being entangled in the rotary plow 21 and causing the rotary plow 21 to be unable to play its role, but also after the grass stems are collected, the grass stems and fertilizers can be crushed together at the same time. After the rotary plow 21 is plowed, the crushing knife 9 can continuously spread the crushed fertilizers and grass stems into the soil while crushing the mud blocks. It has strong functionality, compact structure, and improved efficiency, so that the grass stems can be used in the field. In the process of crushing, the fertilizer and grass stem materials are mixed and then applied to the soil, thereby improving the fertilization effect on the soil. That is, through structural integration and improvement, a new land preparation technology and process can be obtained, the land preparation effect is improved, and the land preparation process is simplified.

[0040] A land preparation method using an ecological garden engineering land preparation device for land preparation mainly includes the following steps: 1) Adjust the height of the rotary tillage plough 21, add fertilizer to the hopper 7, turn on the suction fan 14, move the device forward, the tooth rake 12 grabs the grass stems on the ground, the suction fan 14 sucks the grass stems from the inclined conveying cylinder 11 and the horizontal conveying cylinder 10 into the crushing cylinder 6, and while the inclined conveying cylinder 11 and the horizontal conveying cylinder 10 are transmitting the grass stems, the grass stems are preliminarily crushed, and the crushing knife 37 is turned on, and the crushing knife 37 crushes and mixes the fertilizer and the grass stems; 2) The rotary tillage plow 21 is inserted into the ground, and moves forward while rotating, thereby turning the soil; 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 mud blocks that are turned out, and at the same time, the crushing rod 13 drives the flip 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 flip door 8 to open. At this time, the crushed and mixed grass stems and fertilizers in the crushing cylinder 6 are scattered downward into the soil through the screen 42. In the process of the fertilizer grass stems being scattered into the soil, the nozzle 38 sprinkles water on the fertilizer grass stems to make the fertilizer and grass stems wet; 4) The screed plate 22 levels the soil after fertilization and tillage at the rear side.

[0041] The land preparation method uses an ecological garden engineering land preparation device to prepare the land, so that grass stems are collected, the soil is turned by a rotary plow, and mud blocks are broken and leveled. 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.
