Description

Technical Field

[0001] The present invention relates to the technical field of soil improvement, and in particular to a farmland soil improvement device. Background Art

[0002] Farmland soil improvement devices refer to a series of equipment and technical means used to improve the texture, structure and fertility of farmland soil. The application of these devices and technologies is aimed at optimizing the soil environment, enhancing the biological vitality of the soil, and creating better growth conditions for crops.

[0003] After searching, the Chinese patent with the announcement number CN112772022B discloses a soil compaction improvement and repair device, in which the soil conditioner is alternately applied to the first mixing barrel and the second mixing barrel through an alternate feeding device, and the mixture of water and soil conditioner in the first mixing barrel and the second mixing barrel alternately flows into the soil improvement device through a pipeline, and the mixture of water and soil conditioner flows into the topsoil layer through the discharge hole in the soil improvement device, thereby changing the soil aggregate structure, increasing the soil capillary pores, reducing the soil bulk density, and effectively improving the utilization efficiency of precipitation, thereby improving soil properties and soil fertility; effectively solving the existing problem of low efficiency of manual spraying of conditioners, and the conditioners cannot act on the inside of the soil, and the soil improvement effect is not satisfactory, but the above scheme still has the following shortcomings when actually used: The above scheme utilizes a loosening blade to turn the soil. The soil may contain lumps of soil. Since the lumps of soil often have a certain hardness, when the loosening blade contacts them and turns the soil, the blade will be subjected to continuous friction and impact, causing it to gradually wear out. This wear will shorten its service life, thereby increasing the cost and maintenance workload of farmland soil improvement.

[0016] The present invention has the following beneficial effects: 1. This design drives the rotating block through the motor, which in turn drives the moving block and the push rod under the action of the second spring to move back and forth. The push rod periodically squeezes the fixed block to make the lifting frame move back and forth in the vertical direction. When the lifting frame moves downward, the soil-breaking columns on it can accurately hit the soil blocks on the ground and effectively break the soil blocks. Subsequently, the soil turning equipment can turn the soil and bury the broken soil blocks in the ground. This design not only significantly improves the turning effect of the device on the land, but also effectively avoids excessive wear of the turning blades caused by large pieces of soil, thereby playing a good protective role on the turning equipment and extending its service life; 2. During operation, the motor not only drives the reciprocating movement of the rotating block and the lifting frame to break the soil blocks, but also drives the rotation of the rotating shaft and the water absorbing part through the transmission parts. The axial flow blades built into the water absorbing part effectively perform the pumping action when rotating, extracting water from the water tank and pumping the water into the water spray pipe through the pumping pipe. Since the adjacent water spray pipes are connected through the connecting pipe, the water can smoothly enter all the water spray pipes and be sprayed out in the form of water mist through the atomizing nozzle. These water mists play a dual role in the soil turning process: on the one hand, they effectively suppress the dust generated by the soil turning operation and improve the working environment; on the other hand, the water mist moisturizes the surface soil and reduces the hardness of the soil, which is conducive to the subsequent soil turning equipment to turn the soil more smoothly and efficiently. 3. The lifting frame drives the connecting rod and the sliding plate to move up and down in the fixed cover, driving the alternating operation of the two suction parts. Each suction part is composed of an air bag and two air pipes with one-way valves in opposite limiting directions, ensuring that when the sliding plate squeezes the air bag, the gas in the air bag is pressed into the dust collecting box; and when the sliding plate stretches the air bag, the gas is extracted from the main pipe. This design enables the dust suction ports on several dust suction pipes to continuously and effectively extract the dust generated during the soil turning process, and discharge it into the dust collecting box through the air bag, effectively avoiding the scattering of dust. In addition, the two suction parts arranged inside the fixed cover can perform the suction action alternately, avoiding the window period of the dust suction action, thereby ensuring the continuous and efficient dust absorption effect of the device.

When the soil blocks are broken, the soil turning device 1 will dig the soil and bury the broken soil blocks in the ground. This design can prevent large pieces of soil from causing excessive wear on the soil turning blades on the soil turning device 1, which can not only improve the digging effect of the device on the land, but also protect the soil turning device 1 and extend the service life of the soil turning device 1. The farmland soil improvement device also includes a driving structure, which is arranged on the installation frame 4 and is used to drive the crushing structure to operate.

During the rotation of the rotating block 64, the moving block 65 can reciprocate under the elastic force of the second spring 67, which makes the top rod 66 also reciprocate. During the movement, the top rod 66 can periodically squeeze the inclined surface of the fixed block 610. When the top rod 66 squeezes the inclined surface of the fixed block 610, the fixed block 610 can move upward, and the lifting frame 51 will also move upward. When the top rod 66 and the fixed block 610 are separated from each other, the lifting frame 51 will move downward under the elastic force of the two first springs 57; The lifting frame 51 is provided with a water spraying structure and a water supplying structure, the water spraying structure comprises: a plurality of water spraying pipes 71, all fixed on the inner ring of the lifting frame 51; a plurality of atomizing nozzles 72, respectively mounted on the plurality of water spraying pipes 71; a plurality of connecting pipes 73, two adjacent water spraying pipes 71 are connected through the connecting pipes 73, the water supplying structure comprises: a water pumping seat 81, fixed on the side of the mounting frame 4, the water pumping seat 81 is connected with one of the water spraying pipes 71; a rotating shaft 82, passing through the water pumping seat 81, and being rotatably connected with the water pumping seat 81; a water absorbing member 83, fixed on the rotating shaft 82, the water absorbing member 83 is located inside the water pumping seat 81, the water absorbing member 83 comprises a sleeve and a plurality of axial flow blades, the sleeve is fixedly sleeved on the rotating shaft 82, the plurality of axial flow blades are fixed on the outer peripheral surface of the sleeve, and the plurality of axial flow blades are distributed in a circumferential array; a transmission member 84, The rotating shaft 82 is connected to the output shaft of the motor 62 through a transmission member 84; a water pumping pipe 85 is connected to the water pump seat 81 at one end and to the water tank 2 at the other end. When the rotating shaft 82 rotates, it can drive the water absorbing member 83 to rotate. The water absorbing member 83 includes a plurality of axial flow blades. When the plurality of axial flow blades rotate, the water absorbing member 83 can extract the water flow in the water tank 2 through the water pumping pipe 85 and pump the water flow into the corresponding water spraying pipe 71. Two adjacent water spraying pipes 71 are connected through a connecting pipe 73. Therefore, the water flow will enter the plurality of water spraying pipes 71 and be sprayed out through the plurality of atomizing nozzles 72. The water mist sprayed by the plurality of atomizing nozzles 72 can not only suppress the dust generated during the soil turning process, but also moisten the surface soil and reduce the hardness of the soil. The installation frame 4 is provided with a dust suction structure and an exhaust structure, and the dust suction structure includes: the dust suction structure includes: a main pipe 91, fixed to the side of the installation frame 4; a plurality of dust suction pipes 92, all fixed to the inner circle of the installation frame 4, each dust suction pipe 92 is connected to the main pipe 91; a plurality of dust suction ports 93, respectively opened on the plurality of dust suction pipes 92, and the dust suction structure includes: a fixed cover 101, fixed to the top surface of the installation frame 4; a sliding plate 102, slidably arranged on the inner surface of the fixed cover 101; a sliding plate 102, slidably arranged on the inner surface of the fixed cover 101; a sliding plate 103, slidably arranged on the inner surface of the fixed cover 101; a sliding plate 104, slidably arranged on the inner surface of the fixed cover 101; a sliding plate 105, slidably arranged on the inner surface of the fixed cover 101; a sliding plate 106, slidably arranged on the inner surface of the fixed cover 101; a sliding plate 107, slidably arranged on the inner surface of the fixed cover 101; a sliding plate 108, slidably arranged on the inner surface of the fixed cover 101; a sliding plate 109 ... The slideway 103 is provided on the side of the fixed cover 101; the connecting rod 104 is fixedly connected to the sliding plate 102 at one end and fixedly connected to the lifting frame 51 at the other end, and the connecting rod 104 slides in the slideway 103; two air suction members are arranged inside the fixed cover 101, and the two air suction members are respectively located at the upper and lower ends of the sliding plate 102, and the air suction members include: an air bag 111, one end of which is connected to the inner surface of the fixed cover 101 and the other end is connected to the sliding plate 102; two air suction members are arranged inside the fixed cover 101, and the two air suction members are respectively located at the upper and lower ends of the sliding plate 102. One end of each tube 112 is connected to the air bag 111, the other end of one of the air pipes 112 is connected to the main pipe 91, and the other end of the other air pipe 112 is connected to the dust collecting box 94; two one-way valves 113 are respectively installed on the two air pipes 112; the dust collecting box 94 is arranged on the side of the mounting frame 4, and with the rise and fall of the sliding plate 102, the several dust suction ports 93 on the several dust suction tubes 92 can extract the dust generated in the process of turning the soil, and the air bag 111 discharges the dust-containing airflow into the interior of the dust collecting box 94, thereby collecting the dust generated in the process of turning the soil and preventing the dust from flying around. It is worth mentioning that two suction parts are arranged inside the fixed cover 101. When one of the air bags 111 is squeezed, the other air bag 111 will be stretched, which enables the two suction parts to perform the suction action alternately. By setting two suction parts, it is possible to avoid the existence of a window period in the dust suction action, thereby ensuring the dust absorption effect of the device.

[0021] The specific working principle of the present invention is as follows: When the farmland soil improvement device proposed by the present invention is in use, the tillage device 1 drives the installation frame 4 to move, and the staff starts the motor 62. When the motor 62 is running, it can drive the rotating block 64 to rotate. Since the rotating block 64 and the moving block 65 together form a cylindrical structure, the rotating block 64 and the moving block 65 are of the same size, and the rotating block 64 and the moving block 65 are opposite to each other. The ends are both provided with inclined surfaces, so during the rotation of the rotating block 64, its inclined surface portion can squeeze the inclined surface portion of the moving block 65. Under the limiting action of the limiting rod 68 and the limiting block 69, the moving block 65 cannot rotate with the rotating block 64, so the moving block 65 will move under the squeezing action of the rotating block 64. Therefore, during the rotation of the rotating block 64, the moving block 65 can reciprocate under the elastic force of the second spring 67, which makes the push rod 66 also reciprocate. During the movement, the push rod 66 can periodically squeeze the inclined surface of the fixed block 610. When the push rod 66 squeezes the inclined surface of the fixed block 610, the fixed block 610 can move upward, and the lifting frame 51 will also move upward. When the push rod 66 and the fixed block 610 are separated from each other, the lifting frame 51 will move downward under the elastic force of the two first springs 57. Based on the above process, during the operation of the motor 62, the lifting frame 51 will reciprocate in the vertical direction. When the lifting frame 51 moves downward, a plurality of soil crushing columns 53 can hit the soil blocks on the ground downward. The soil blocks will be broken when impacted by the soil crushing columns 53, that is, the plurality of soil crushing columns 53 can crush the soil blocks on the ground. When the soil blocks are broken, the soil turning device 1 will dig the soil and bury the broken soil blocks in the ground. This design can prevent large pieces of soil from causing excessive wear on the soil turning blades on the soil turning device 1, which can not only improve the digging effect of the device on the land, but also protect the soil turning device 1 and extend the service life of the soil turning device 1. When the motor 62 is running, it can also drive the rotating shaft 82 to rotate through the transmission member 84. When the rotating shaft 82 rotates, it can drive the water absorbing member 83 to rotate. The water absorbing member 83 includes a plurality of axial flow blades. The plurality of axial flow blades can perform a pumping action when rotating. Therefore, with the operation of the motor 62, the water absorbing member 83 can extract the water flow in the water tank 2 through the pumping pipe 85, and pump the water flow into the corresponding water spray pipe 71. The two adjacent water spray pipes 71 are connected by the connecting pipe 73, so the water flow will enter the plurality of water spray pipes 71 and be sprayed out through the plurality of atomizing nozzles 72. The water mist sprayed by the plurality of atomizing nozzles 72 can not only suppress the dust generated during the soil turning process, but also moisten the surface soil and reduce the hardness of the soil, which is beneficial to the subsequent soil turning device 1 to turn over the soil. It is worth noting that the transmission member 84 accelerates the rotation speed of the motor 62, which enables the rotating shaft 82 and the water absorbing member 83 to rotate at a high speed. The high-speed rotation of the water absorbing member 83 is the key to ensuring the pumping effect. When the lifting frame 51 moves up and down, the lifting frame 51 can drive the connecting rod 104 to move up and down. When the connecting rod 104 moves up and down, it can drive the sliding plate 102 to move up and down inside the fixed cover 101. In this process, the sliding plate 102 will drive the two suction parts to operate. For the suction parts, two air pipes 112 are connected to the air bag 111. Both air pipes 112 are equipped with one-way valves 113, and the flow limiting directions of the two one-way valves 113 are opposite. Specifically, one of the one-way valves 113 limits the airflow to only enter the interior of the air bag 111, and the other one-way valve 113 limits the airflow to only flow out of the interior of the air bag 111. Therefore, when the sliding plate 102 squeezes the air bag 111, the gas inside the air bag 111 will be pressed out and enter the collecting Inside the dust box 94, when the sliding plate 102 stretches the airbag 111, the airbag 111 can extract the gas in the main pipe 91 through the corresponding air pipe 112. Based on the above process, along with the rising and falling of the sliding plate 102, the several dust suction ports 93 on the several dust suction pipes 92 can extract the dust generated in the soil turning process, and the airbag 111 discharges the dust-laden airflow into the dust collecting box 94, thereby collecting the dust generated in the soil turning process and preventing the dust from flying everywhere. It is worth mentioning that two suction parts are arranged inside the fixed cover 101. When one of the airbags 111 is squeezed, the other airbag 111 will be stretched, which enables the two suction parts to perform the suction action alternately. By setting up two suction parts, it is possible to avoid the existence of a window period in the dust suction action, thereby ensuring the dust absorption effect of the device.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
