Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery and equipment, in particular to a towable soil improver for shallow soil turning and improvement. Background Art

[0002] With the rapid development of modern agriculture and the advancement of ecological restoration projects, soil improvement has become a key component in increasing land productivity and ensuring sustainable agricultural development. Due to factors such as long-term continuous cropping and excessive use of chemical fertilizers, soil compaction, decreased fertility, and acid-base imbalances have become increasingly prominent. This structural damage to shallow soils is particularly pronounced, directly impacting crop growth and yield. Therefore, efficient shallow soil improvement technologies have become a critical and pressing issue in the agricultural sector.

[0003] The Chinese invention patent application with publication number CN102668756A discloses an all-in-one machine for improving and finishing soil for cultivating salvia miltiorrhiza, comprising a frame, a power input shaft, a soil-raising section, a soil-mixing section, and an auxiliary material adding section. The frame is a welded structure for mounting other components; the soil-raising section comprises a plurality of plow blades fixed to the soil inlet on the front side of the soil-mixing chamber for turning the soil; the soil-mixing section is used to mix the soil and auxiliary materials; the auxiliary material adding section is used to add auxiliary materials; and the power input shaft is mounted on the frame for power transmission. The present invention first uses a tractor to pull the improver, and the plow blades on the front side of the improver bring the surface soil into the improver. Then, the opening of the auxiliary material storage box for organic fertilizer and straw is opened, and the straw and organic fertilizer are continuously added, mixed, and added to the soil. The soil is unloaded from the improver, the soil covering wheel is used to standardize it, and the mulch covering wheel is used to cover the mulch with film, thus completing the soil improvement work. Subsequently, the soil covering wheel and the mulch covering roller cooperate to compact the soil and cover it with film.

[0004] However, although the above patent can achieve the mixing of soil and auxiliary materials, the mixed soil will form several ridges after the action of the soil covering wheel, and the raised soil will easily pass over the top of the covering roller when the subsequent covering roller passes through for covering. It can be seen that the above patent cannot timely and well flatten the processed soil, and the soil will be forced to be compacted when it is flattened by structures such as the covering wheel, and the soil improver mixed in it cannot fully contact with the air, and the effect will be reduced.

[0005] Based on this, the present invention is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0048] like Figure 1 and Figure 2 As shown, the shallow soil improvement dragging type soil improver includes: a base 1, a bucket 2, a feeding mechanism 3, a frame 4, a soil turning mechanism 5, a driving mechanism 6, a bracket 7, a hopper 8 and a material distribution mechanism 9.

[0049] An outer cover 100 is installed on the top of the base 1, and the outer cover 100 is used to protect the internal equipment. A traction arm 1001 is installed on the outer cover 100, and the traction arm 1001 is used to connect with an external traction device. The device of the present application can be connected to a tractor or other equipment to tow the device forward. Two wheels 200 are rotatably installed on both sides of the base 1. The bucket 2 is rotatably installed on the base 1, and a number of teeth 201 are equidistantly installed on the bucket 2. The teeth 201 are wedge-shaped, which helps to insert into the soil for shoveling. An electric push rod 202 is rotatably installed on the base 1, and the output end of the electric push rod 202 is rotatably installed on the side wall of the bucket 2. Turning on the electric push rod 202 can rotate the bucket 2, thereby realizing the work of turning over and dumping the soil.

[0050] refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8The feeding mechanism 3 is mounted on the base 1 and is used to transport the soil into the base 1 and turn it over. The feeding mechanism 3 includes: a first gear roller 31, a first toothed belt 32, a roller 33, a rotating roller 34, a guide groove 35, a second slide bar 36, a second slider 37, a second drive rod 38, a flap 39, a second motor 310, a protective shell 311, a third motor 312, a gear 313, a second toothed belt 314, and a limiting roller 315. There are two first gear rollers 31, which are symmetrically mounted in the base 1. The main body of the first gear roller 31 is a rotating roller, and a plurality of teeth are installed at both ends of the rotating roller at equal intervals along the circumference. The first toothed belt 32 is meshed and connected with the two first gear rollers 31. The width of the first toothed belt 32 matches the length of the first gear roller 31, ensuring it covers the first gear roller 31. The teeth of the first toothed belt 32 mesh with the teeth at each end of the first toothed belt 32, enabling the two first gear rollers 31 to rotate synchronously. Furthermore, the surface of the first toothed belt 32 is provided with anti-slip grooves, allowing soil to fall onto it and be transported by the first toothed belt 32. Several idler rollers 33 are equidistantly mounted and rotated between the two first gear rollers 31. These idler rollers 33 support the first toothed belt 32, ensuring stable operation and precise feeding. A second motor 310 is mounted outside the base 1, with its output connected to one of the first gear rollers 31. Turning on the second motor 310 drives the connected first gear roller 31 to rotate. Several sets of horizontal pushers are also equidistantly mounted within the base 1 to laterally shift soil that has fallen onto the top of the first toothed belt 32. The structure of the transverse pushing component is as follows: there are two rollers 34, which are rotatably installed in the base 1. There are several guide grooves 35, which are equidistantly arranged. Each guide groove 35 is connected end to end and is opened on the roller 34, and the two guide grooves 35 are symmetrical to each other. There are two second slide bars 36, which are respectively installed in the base 1. There are several second sliders 37, which are equidistantly slidably installed on the two second slide bars 36. The second slider 37 can move along the axial direction of the second slide bar 36, and the two second slide bars 36 are limited to ensure that the second slider 37 slides stably and does not rotate. The second drive rod 38 is installed on the upper surface of the second slider 37, and the second drive rod 38 is slidably installed in the guide groove 35. When the roller 34 rotates, the second drive rod 38 can move back and forth along the axial direction of the roller 34 by utilizing the limitation of the guide groove 35. The flap 39 is mounted on the lower surface of the second slider 37 and is tilted 45 degrees relative to the axis of the roller 34. This ensures that when the flap 39 moves along the axis of the rotating shaft 34, it has sufficient contact area with the soil to facilitate stirring and stirring, while also being able to tilt in contact with the soil to facilitate relative movement with the soil and avoid excessive resistance. The protective shell 311 is mounted on the side of the base 1.The third motor 312 is mounted on the protective shell 311. There are several gears 313, which are rotatably mounted in the protective shell 311. Each two gears 313 form a group, and each group of two gears 313 is respectively connected to two rollers 34 in each group of transverse pushing components. One of the gears 313 is connected to the output end of the third motor 312. Turning on the third motor 312 can drive the gear 313 connected to it to rotate. The second toothed belt 314 is meshed with several gears 313. The transmission of the second toothed belt 314 can make each gear 313 rotate synchronously. There are several limiting rollers 315, which are in rolling contact with the second toothed belt 314 respectively. Their positions correspond to each gear 313, which can limit the second toothed belt 314 to avoid tooth jumping.

[0051] Frame 4 is mounted on the upper surface of base 1; bracket 7 is mounted on top of frame 4, and hopper 8 is mounted on bracket 7. Hopper 8 is filled with soil conditioner, which is allowed to fall onto base 1. A feeding mechanism 3 mixes the soil and conditioner and transports them in a directional manner until they fall back to the ground. An outlet is defined on the side of base 1 away from hopper 2 to ensure that the soil can fall back through this outlet.

[0052] The specific operating principle of the above structure is as follows: A tractor or other external traction device is connected to the traction arm 1001 and dragged to move the device. The electric push rod 202 is activated to rotate the tipping bucket 2. The teeth 201 penetrate the soil, scooping the surface soil in the forward direction into the tipping bucket 2. The electric push rod 202 then reverses, dumping the soil into the base 1 and onto the first toothed belt 32. The third motor 312 is activated to rotate the gears 313 connected to it. Through the linkage of the second toothed belt 314, the gears 313 rotate synchronously, driving the rollers 34 to rotate. The guide grooves 35 limit the second drive rod 38, causing the second slider 37 to reciprocate, and the shovel plate 39 to turn the soil. Because the guide grooves 35 on adjacent rollers 34 are symmetrical, the two sets of flaps 39 reciprocate in opposite directions. During this process, the soil conditioner in the hopper 8 falls into the base 1 and is mixed with the soil due to the turning of the feed mechanism 3. At the same time, the second motor 310 is turned on to drive the first gear roller 31 connected to it. The other first gear roller 31 rotates synchronously by the linkage of the first toothed belt 32. The soil is transported away from the bucket 2 by the first toothed belt 32 and finally falls back to the ground.

[0053] This structure can be used to scoop up the shallow soil, mix it with the soil conditioner independently, and then transport it back to the ground in a directional manner to improve the shallow soil. The guide groove 35 can be used to make the two adjacent groups of flaps 39 rotate back and forth in opposite directions, thereby improving the mixing and turning effect.

[0054] In actual use, the soil that falls back to the ground will accumulate into piles. In order to better flatten the soil, the following solutions are proposed: Figure 7 and Figure 9 The soil turning mechanism 5 is installed on the side of the base 1 away from the bucket 2. The soil turning mechanism 5 includes: a mounting frame 51, a first slide bar 52, a first slider 53, a first movable frame 54, a second movable frame 55, a shifting rod 56 and a first driving rod 57. There are two mounting frames 51, which are symmetrically mounted on the frame 4. There are two first slide bars 52, which are respectively mounted between the two mounting frames 51. There are two first sliders 53, which are both slidably mounted on the two first slide bars 52. The first slider 53 can slide along the axial direction of the first slide bar 52. The common limit of the two first slide bars 52 can ensure that the first slider 53 slides stably and will not flip over. The first movable frame 54 and the second movable frame 55 are respectively mounted on the lower surfaces of the two first sliders 53. The first movable frame 54 is set in a U shape, and the second movable frame 55 is set in a straight line. The second movable frame 55 is installed on the inner side of the first movable frame 54 through the opening position of the first movable frame 54 to avoid interference when the two move. A plurality of levers 56 are equidistantly mounted on the lower surfaces of the first mobile frame 54 and the second mobile frame 55, with their bottom ends in contact with the ground. A first drive rod 57 is mounted on the upper surface of the first slider 53 and is controlled to drive the first and second mobile frames 54, 55 to move independently.

[0055] The first driving rod 57 can be driven to move by the driving mechanism 6. Figure 7 、 Figure 9 and Figure 10The driving mechanism 6 is mounted on the frame 4, and the driving mechanism 6 corresponds to the position of the soil turning mechanism 5. The driving mechanism 6 includes: two driving wheels 61, a reducer 62, a first motor 63 and a rotating shaft 64. The reducer 62 is mounted on the frame 4, and the reducer 62 uses a dual-output end model, which is an existing device. The driving wheel 61 is eccentrically arranged, and the two driving wheels 61 are respectively the first driving wheel 61a and the second driving wheel 61b. The first driving wheel 61a is rotatably mounted on the lower surface of the frame 4 and is connected to one output end of the reducer 62. One end of the rotating shaft 64 is connected to the other output end of the reducer 62, and the other end of the rotating shaft 64 is connected to the second driving wheel 61b. The first motor 63 is mounted on the reducer 62, and the output end of the first motor 63 is connected to the input end of the reducer 62. Turning on the first motor 63 can drive the first driving wheel 61a and the second driving wheel 61b to rotate synchronously. The driving wheel 61 is also equipped with at least one first protrusion 6101 and a second protrusion 6102. The length of the first protrusion 6101 from the center of the driving wheel 61 is greater than the length from the second protrusion 6102 to the center of the driving wheel 61. A limiting groove 6103 is provided on the driving wheel 61. The limiting groove 6103 is provided along the edge of the driving wheel 61, the first protrusion 6101 and the second protrusion 6102 and is the same at both ends, closed into a loop shape, and the first driving rod 57 is slidably installed in the limiting groove 6103.

[0056] The actual working principle of the above structure is as follows: Turning on the first motor 63 rotates the output end of the reducer 62, thereby rotating the first drive wheel 61a. Then, using the limit groove 6103 to limit the first drive rod 57 along the axial direction of the first slide bar 52, the first drive rod 57 moves a large distance when it corresponds to the first protrusion 6101, and a small distance when it corresponds to the second protrusion 6102. At the same time, in this invention, the first protrusion 6101 and the second protrusion 6102 are symmetrically arranged around the center of the drive wheel 61, ensuring that when the first drive rod 57 corresponding to the first drive rod 57 of the first mobile frame 54 corresponds to the first protrusion 6101, the first drive rod 57 corresponding to the second mobile frame 55 corresponds to the second protrusion 6102. This ensures that the first mobile frame 54 and the second mobile frame 55 move in an alternating manner with different distances. Then, the various shifting rods 56 are used to stagger the movement to level the piled soil.

[0057] In addition, reference Figure 3 、 Figure 5 and Figure 11A discharge bag 10 is installed at the bottom of the hopper 8. The discharge bag 10 is made of a flexible material. When pulled, the internal space will change, reducing the friction between the originally accumulated powdered soil conditioner particles. At the same time, under the action of gravity and the extrusion force generated by the bag deformation, the material is forced to flow. A discharge pipe 11 is installed at the bottom of the discharge bag 10. An electric valve 12 is installed on the discharge pipe 11. The electric valve 12 is an existing device. The controlled opening and closing can control the opening or closing of the passage of the discharge pipe 11. A cloth mechanism 9 is installed in the outer cover 100. The cloth mechanism 9 corresponds to the position of the discharge bag 10. The cloth mechanism 9 is used to pull the discharge bag 10 to prevent the powdered soil conditioner from being blocked. The cloth mechanism 9 includes: a third slide bar 91, a third slider 92, a connecting rod 93, an extension rod 94 and a third drive rod 95. There are two third slide bars 91, symmetrically mounted in the outer housing 100. A third slider 92 is slidably mounted on the two third slide bars 91. The third slider 92 can move axially along the third slide bars 91, and the two third slide bars 91 limit the third slider 92 to ensure stable sliding. A connecting rod 93 is mounted between the third slide bar 92 and the discharge bag 10, with the free end of the connecting rod 93 sewn to the discharge bag 10. An extension rod 94 is mounted on the lower surface of the third slide bar 92; a third drive rod 95 is mounted on the extension rod 94 and slidably mounted in the limit slot 6103 of the drive wheel 61 at the top. When the driving mechanism 6 drives the soil-turning mechanism 5, the second driving wheel 61b at the top rotates synchronously, and then uses its limiting groove 6103 to limit the third driving rod 95, causing the third slider 92 to move back and forth, and the connecting rod 93 to pull the discharge bag 10. At the same time, the first protrusion 6101 and the second protrusion 6102 are configured to ensure uneven pulling of the discharge bag 10. This uneven pulling can break up the arch bridge structure formed by the friction and electrostatic effects between the particles of the powdered soil conditioner, preventing blockage. At the same time, the varying pulling forces cause the bag to deform irregularly, further promoting the flow of the internal material and allowing the powdered soil conditioner to fall smoothly. In actual use, the discharge bag 10 is continuously and irregularly pulled to ensure that the conditioner is always loose and fluid. At the same time, the electric valve 12 is intermittently controlled to open and close, so that the soil conditioner can be intermittently delivered according to demand.

[0058] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
