Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, specifically to an agricultural planting soil loosening device. Background Technology

[0002] Agricultural soil loosening equipment is used to loosen agricultural soil. Before planting agricultural crops, the soil needs to be loosened sufficiently before seeds can be applied to the loosened soil to cultivate agricultural products.

[0003] For example, an agricultural soil loosening device with announcement number CN112970356B includes a control box, rollers, a push handle, a feed trough, and a working box. The rear end of the control box is embedded and fixedly connected to the front end of the working box. The inner side of the rollers is movably engaged with the outer side of the working box. The left end of the push handle is welded and connected to the right end of the working box. The lower end of the feed trough is riveted and connected to the upper end of the working box. Seeds are placed into the feed trough and enter the storage box. The device is pushed to the position where soil loosening is needed by the rollers. Power is turned on, and the control box is operated to make the rotating shaft drive the soil loosening device to rotate, so that the scraper squeezes the soil. Through the device in the drive wheel, the slide rail and slider are driven to rotate, so that the slider drives the spring rod in the telescopic frame to extend and retract in the slide rail. The slider hits the support plate to generate vibration, which prevents soil from sticking to the scraper and causing the scraper to be covered with soil, resulting in poor soil loosening effect.

[0004] However, during the soil loosening process, some soil and weeds will stick to the scraper, which increases the scraper's resistance and affects the loosening depth and uniformity, resulting in poor soil breaking effect. In addition, debris stuck on the scraper can also cause deformation of the scraper, reducing the quality of the loosening operation. At the same time, due to the influence of soil, when the device moves, the height on both sides is different, and the depth of the scraper in the soil on both sides is also different, which will lead to deviations in the uniformity of soil loosening, which will also reduce the quality of soil loosening.

[0005] Therefore, an agricultural soil loosening device was proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an agricultural soil loosening device to solve the problem that soil and weeds adhering to the scraper affect the soil loosening depth and uniformity, resulting in poor soil breaking effect and inconsistent scraper penetration depth, which leads to deviations in soil loosening uniformity.

[0014] Preferably, a push rod is fixedly connected to the back of the outer casing, and a control device is also fixedly installed inside the outer casing.

The horizontal shaft is rotatably connected to the bending plate on the other side, and the loosening wheel is evenly fixedly installed on the outside of the horizontal shaft.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up a soil loosening assembly, and utilizing the cooperation of components such as the air guide pipe and sliding seat in the jet unit, the air guide pipe moves laterally and longitudinally when the soil loosening wheel rotates to loosen the soil. This allows the air guide pipe to move and jet air onto the top of multiple soil loosening wheels, maintaining the overall cleaning of the top surface of the soil loosening wheels. This achieves automatic multi-directional overall cleaning, reduces cleaning dead corners, and thus reduces the amount of soil and other debris adhering to the soil loosening wheel, maintaining the soil breaking effect and improving the quality of soil loosening. Utilizing the cooperation of components such as the contact plate and clamping rod in the side pressure unit, the contact plate presses firmly against the soil on both sides of the device. While cleaning the soil loosening wheel, it also drives multiple clamping rods to continuously assist in pressing down and clamping the contact plate, thereby keeping the device in a horizontal state, reducing height deviation on both sides of the device, and ensuring that the soil loosening wheels on both sides penetrate the soil to the same depth, thereby improving the uniformity of soil loosening and improving the quality of soil loosening. The specific details are as follows: 1. By setting up the soil loosening component, the operator moves the outer casing by pushing the rod, and the contact plate presses against the soil on both sides of the outer casing. By starting the auxiliary motor, the auxiliary motor drives the horizontal shaft and the soil loosening wheel to rotate, facilitating soil loosening. The hydraulic rod extends and retracts to adjust the loosening depth of the soil loosening wheel. At the same time, the servo motor drives the main gear and the first reciprocating screw to rotate. The rotation of the first reciprocating screw causes the moving rod to move back and forth. The moving rod drives the top block and the sliding seat to move. The sliding seat slides longitudinally inside the bottom groove. The sliding seat drives the inclined plate and the air guide pipe to move longitudinally. The inclined plate is squeezed by the fixed rod. The inclined plate also drives the longitudinal bar and the sliding rod to move. The longitudinal bar compresses the spring. The inclined plate also drives the air guide pipe to move laterally, so that the air guide pipe moves and sprays air onto the top of multiple soil loosening wheels to maintain soil loosening. The top surface of the wheel is cleaned as a whole, achieving automatic multi-directional overall cleaning, reducing cleaning dead corners, thereby reducing the amount of soil and other debris adhering to the loosening wheel, maintaining the soil breaking effect, and improving the quality of loosening. Spring three is initially in a compressed state, and the main gear will also drive the driven gear to rotate. The rotation of the driven gear will drive the extrusion plate to move back and forth. The extrusion plate extrudes the inclined surface of the trapezoidal block, causing the trapezoidal block to descend. The trapezoidal block compresses spring two and drives the clamping rod to descend. The clamping rod slides into the fixed cylinder and further compresses spring three, so that spring three will always provide downward pressure on the fixed cylinder and the contact plate, thereby keeping the device in a horizontal state, reducing the height deviation on both sides of the device, and keeping the soil loosening wheel on both sides at the same depth, thereby improving the uniformity of loosening and improving the quality of loosening. 2. By setting up the sowing component, the seeds are placed in the feeding trough. By starting the drive motor, the drive motor drives the rotating rod and the stirring plate to rotate. The seeds enter the lower box through the strip trough, fall into the cylinder from the upper trough, are separated by the stirring plate, and then fall into the loosened soil from the lower trough. This realizes the automatic integration of loosening the soil and sowing, which facilitates the even distribution and sowing of seeds. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 - Figure 3 The present invention provides a technical solution: an agricultural planting soil loosening device, including an outer shell 1 and walking wheels 2 rotatably installed around the bottom of the outer shell 1, and an air compressor 6 fixedly installed on one side of the top of the outer shell 1.

[0021] A soil loosening component 4 is provided on one side of the inner shell 1. An air guide pipe 416 is fixedly connected to the outlet end of the air compressor 6. A soil loosening wheel 12 is installed horizontally and longitudinally inside the outer shell 1. Multiple air guide pipes 416 are provided. The air guide pipes 416 are used to clean the top of the soil loosening wheel 12 as a whole, reduce soil adhesion, and improve the soil loosening effect. There are no less than three soil loosening wheels 12. The number of air guide pipes 416 is the same as that of the soil loosening wheel 12.

[0022] like Figure 1 and Figure 3 - Figure 11 As shown, the soil loosening component 4 includes an air jet unit and a side pressure unit. The air jet unit includes a fixed box 41 that is fixedly connected to one side of the top surface inside the outer shell 1. Sliding seats 43 are evenly installed on the bottom of the fixed box 41. The sliding seats 43 can slide along the length direction (i.e., horizontal longitudinal direction) of the fixed box 41.

[0023] The bottom of the fixed box 41 has a bottom groove 42 longitudinally formed. The sliding seat 43 is slidably connected to the bottom groove 42. The top block 44 is fixedly connected to the top of the sliding seat 43. Side boxes 45 are fixedly connected to both sides of the outer shell 1. A servo motor 46 is fixedly installed inside the side box 45. A main gear 47 is fixedly connected to the output end of the servo motor 46. A first reciprocating screw 48 is fixedly connected to one side of the main gear 47. The first reciprocating screw 48 is rotatably connected to the side box 45.

[0024] A sloping plate 414 is slidably installed at the bottom of the sliding seat 43. The sloping plate 414 can slide along the width direction (i.e., horizontal) of the fixed box 41, so that the sloping plate 414 can drive the air pipe 416 to move horizontally and vertically. The gas sprayed out by the air pipe 416 can uniformly spray and clean the top surface of the loosening wheel 12. The side pressure unit includes contact plates 427 symmetrically installed on both sides of the outer shell 1.

[0025] The outer side of the first reciprocating screw 48 is threaded with a sliding sleeve 49. A moving rod 410 is fixedly connected between the two sliding sleeves 49. The moving rod 410 is slidably connected to the outer casing 1. The moving rod 410 passes through the fixed box 41 and is fixedly connected to the top block 44. The bottom of the sliding seat 43 is fixedly connected to a bottom block 411. A sliding rod 412 is slidably connected laterally inside the bottom block 411. A longitudinal bar 413 is fixedly connected to one end of the sliding rod 412. The longitudinal bar 413 is fixedly connected to the inclined plate 414. The air guide pipe 416 is fixedly installed on the inclined plate 414. The air guide pipe 416 is a telescopic hose with installation joints at both ends to facilitate the adjustment of the position of the air guide pipe 416 and to facilitate uniform jet cleaning.

[0026] Only one longitudinal bar 413 is provided, and multiple sliding rods 412 are fixedly connected to the same longitudinal bar 413. The number of sliding rods 412 is the same as the number of sliding seats 43, and the number of sliding seats 43 is the same as the number of loosening wheels 12.

[0027] A fixing rod 417 is fixedly connected to one side of the inner shell 1. The fixing rod 417 abuts against the inclined surface of the inclined plate 414. A spring 415 is sleeved on the outer side of the slide rod 412. The two ends of the spring 415 are fixedly connected to the bottom block 411 and the longitudinal bar 413, respectively. A second reciprocating screw 418 is also rotatably connected inside the side box 45. A driven gear 419 is fixedly connected to one end of the second reciprocating screw 418. The driven gear 419 meshes with the main gear 47. A pressing plate 420 is threadedly connected to the outer side of the second reciprocating screw 418. The pressing plate 420 is slidably connected to the side box 45.

[0028] Side plates 421 are fixedly connected to both sides of the outer shell 1. A clamping rod 422 is vertically slidably connected inside the side plate 421. A trapezoidal block 423 is fixedly connected to the top of the clamping rod 422. A second spring 424 is sleeved on the outside of the clamping rod 422. The two ends of the second spring 424 are fixedly connected to the side plate 421 and the trapezoidal block 423 respectively. A fixed cylinder 425 is slidably connected to the outside of the clamping rod 422. A third spring 426 is fixedly connected to the inner bottom surface of the fixed cylinder 425. The top of the third spring 426 is fixedly connected to the clamping rod 422. A contact plate 427 is fixedly connected to the bottom of the fixed cylinder 425.

[0029] Damping blocks are provided at both ends of spring 1 415, spring 2 424 and spring 3 426 to reduce their reciprocating vibration and maintain stable extension and contraction. Spring 3 426 is initially in a compressed state, so that when the extrusion plate 420 slides, the contact plate 427 will always be pressed against the soil, keeping the outer shell 1 horizontal and reducing the deviation of the soil penetration depth of the loosening wheels 12 on both sides.

[0030] A push rod 3 is fixedly connected to the back of the outer casing 1, and a control device 7 is also fixedly installed inside the outer casing 1.

[0031] Hydraulic rods 8 are symmetrically fixedly installed on both sides of the inner wall of the outer shell 1. The telescopic end of the hydraulic rods 8 is fixedly connected to a bending plate 9. An auxiliary motor 10 is fixedly installed on the outside of one side of the bending plate 9. The output end of the auxiliary motor 10 passes through the bending plate 9 and is fixedly connected to a horizontal shaft 11. The horizontal shaft 11 is rotatably connected to the other side of the bending plate 9. The loosening wheel 12 is evenly fixedly installed on the outside of the horizontal shaft 11.

[0032] Example 1: As Figure 3 - Figure 11 As shown, the operator moves the outer casing 1 by pushing the push rod 3, and the contact plate 427 presses against the soil on both sides of the outer casing 1. By starting the auxiliary motor 10, the auxiliary motor 10 drives the horizontal shaft 11 and the loosening wheel 12 to rotate, which facilitates the loosening of the soil. The hydraulic rod 8 extends and retracts to adjust the loosening depth of the loosening wheel 12. At the same time, the servo motor 46 drives the main gear 47 and the first reciprocating screw 48 to rotate. The rotation of the first reciprocating screw 48 causes the moving rod 410 to move back and forth. The moving rod 410 drives the top block 44 and the sliding seat 43 to move. The sliding seat 43 slides longitudinally inside the bottom groove 42. The sliding seat 43 drives the inclined plate 414 and the air guide pipe 416 to move longitudinally.

[0033] Furthermore, the inclined plate 414 is squeezed by the fixed rod 417, and the inclined plate 414 will also drive the longitudinal bar 413 and the sliding rod 412 to move. The longitudinal bar 413 compresses the spring 415, and the inclined plate 414 will also drive the air pipe 416 to move laterally, so that the air pipe 416 moves and sprays air on the top of multiple loosening wheels 12, maintaining the overall position of the top surface of the loosening wheel 12 for cleaning. This achieves automatic multi-directional overall cleaning, reduces cleaning dead corners, thereby reducing the amount of soil and other debris attached to the loosening wheel 12, maintaining the soil breaking effect, and improving the quality of loosening the soil.

[0034] Spring 426 is initially compressed. The main gear 47 drives the driven gear 419 to rotate. The rotation of the driven gear 419 drives the pressing plate 420 to move back and forth. The pressing plate 420 presses the inclined surface of the trapezoidal block 423, causing the trapezoidal block 423 to descend. The trapezoidal block 423 compresses spring 424 and drives the clamping rod 422 to descend. The clamping rod 422 slides into the fixed cylinder 425 and further compresses spring 426, so that spring 426 will always provide downward pressure on the fixed cylinder 425 and the contact plate 427, thereby keeping the device in a horizontal state, reducing the height difference on both sides of the device, and keeping the soil loosening wheel 12 on both sides at the same depth, thereby improving the uniformity of soil loosening and improving the quality of soil loosening.

[0035] like Figure 1 and Figure 12 - Figure 14 As shown, a seeding component 5 is provided at the top center of the outer shell 1. The seeding component 5 includes a cylinder 55 that is uniformly fixed inside the outer shell 1. The cylinder 55 is used to assist in uniform seeding.

[0036] The seeding assembly 5 also includes a feed trough 51 fixedly connected to the top of the outer shell 1. A strip groove 53 is opened in the middle of the top of the outer shell 1. A lower box 54 is fixedly connected to the inner top surface of the outer shell 1. A drive motor 52 is fixedly installed on one side of the inner wall of the feed trough 51. A cylinder 55 is evenly fixedly connected to the bottom of the lower box 54. A rotating rod 56 is fixedly connected to the output end of the drive motor 52.

[0037] Inside the cylinder 55, fixed disks 57 are symmetrically fixedly connected at the top and bottom. Rotating rod 56 is rotatably connected to fixed disks 57. Stirring plates 58 are symmetrically fixedly connected to the outside of rotating rod 56. Stirring plates 58 are located between the upper and lower fixed disks 57. An upper groove 59 is opened on one side of the upper fixed disk 57, and a lower groove 510 is opened on one side of the lower fixed disk 57. The upper groove 59 and the lower groove 510 are not located on the same vertical axis.

[0038] Example 2: Figure 12 - Figure 14 As shown, the seeds are placed in the feeding trough 51. By starting the drive motor 52, the drive motor 52 drives the rotating rod 56 and the stirring plate 58 to rotate. The seeds enter the lower box 54 through the strip groove 53, and fall into the cylinder 55 from the upper groove 59. They are separated by the stirring plate 58 and then fall into the loosened soil from the lower groove 510. This realizes the automatic integration of loosening the soil and sowing, which facilitates the even distribution and sowing of the seeds.

[0039] Working principle: When using this device, firstly, as... Figure 1 - Figure 14 As shown, by starting the auxiliary motor 10, the auxiliary motor 10 drives the horizontal shaft 11 and the loosening wheel 12 to rotate, facilitating soil loosening. The servo motor 46 drives the main gear 47 and the first reciprocating screw 48 to rotate. The rotation of the first reciprocating screw 48 causes the moving rod 410 to move back and forth. The sliding seat 43 drives the inclined plate 414 and the air guide pipe 416 to move longitudinally. The inclined plate 414 also drives the air guide pipe 416 to move laterally, so that the air guide pipe 416 moves and sprays air onto the top of the multiple loosening wheels 12, keeping the top surface of the loosening wheels 12 clean and reducing the amount of soil and other debris adhering to the loosening wheels 12. The spring 3 426 is initially in a compressed state. Gear 47 also drives the driven gear 419 to rotate. The rotation of the driven gear 419 drives the pressing plate 420 to move back and forth. The pressing plate 420 presses the inclined surface of the trapezoidal block 423, causing the trapezoidal block 423 to descend. The trapezoidal block 423 compresses the second spring 424 and drives the clamping rod 422 to descend. The clamping rod 422 slides into the fixed cylinder 425 and further compresses the third spring 426, so that the third spring 426 will always provide downward pressure on the fixed cylinder 425 and the contact plate 427, thereby keeping the device in a horizontal state, reducing the height difference on both sides of the device, and keeping the soil loosening wheel 12 on both sides at the same depth, thereby improving the uniformity of soil loosening and improving the quality of soil loosening.
