Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and equipment technology, and in particular relates to a plant cleaning device for creeping plants. Background Technology

[0002] For some creeping plants, such as strawberries and sweet potatoes, ridge planting is mostly used. During planting, the ridges need to be covered with mulch. In actual production, after harvesting, the stems, leaves, roots, and mulch of these crops need to be cleaned to reduce pests and diseases.

[0003] After harvesting, the stems, leaves, roots, and mulch covering the ridges of crops are often left untreated. Roots returned directly to the field are mostly intact, making them difficult to ferment and hindering the planting and growth of the next crop, while also increasing their susceptibility to pests. Alternatively, manually removing the stems, leaves, roots, and mulch is time-consuming and labor-intensive. Furthermore, when removing the roots, some remain in the soil, making thorough root removal impossible. These remaining roots are highly susceptible to pests.

[0004] Therefore, there is an urgent need for a device that efficiently collects crop roots, stems, leaves, and mulch film covering the ridges. Summary of the Invention

Detailed Implementation

[0027] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0028] Please refer to Figures 1 to 8 A plant cleaning device for creeping plants includes a frame 10, a stem and leaf collection mechanism 20, a film collection mechanism 30 and a root collection mechanism 40. The stem and leaf collection mechanism 20, the film collection mechanism 30 and the root collection mechanism 40 are sequentially arranged on the frame 10, and a walking mechanism 101 is provided on the frame 10. The stem and leaf collection mechanism 20 includes a stem and leaf collection knife 201, a stem and leaf conveyor belt 202, and a stem and leaf collection assembly 203. The stem and leaf collection knife 201 is mounted on the frame 10. One end of the stem and leaf collection conveyor belt is located behind the stem and leaf collection knife 201. The stem and leaf collection assembly 203 is located below the other end of the stem and leaf conveyor belt 202 and is used to collect the stems and leaves of crops. The membrane collection mechanism 30 is used to collect the mulch film; The root collection mechanism 40 includes a shovel 401, a root conveyor belt 402, and a root-soil separation component 403. The shovel 401 is mounted on the frame 10. One end of the root conveyor belt 402 is located behind the shovel 401. The root-soil separation component 403 is located below the other end of the root conveyor belt 402. The root-soil separation component 403 is used to separate the soil from the rhizome.

[0029] The walking mechanism 101 drives the frame 10 to move, and the frame 10 in turn drives the stem and leaf collection mechanism 20, the film collection mechanism 30, and the root collection mechanism 40 to move. The creeping plant clearing device collects the leaves, stems, and roots with soil from the crops. In use, the film collection mechanism 30 first cuts the plastic film covering the soil. The film collection assembly can be a collection reel and film-breaking blades set on both sides of the collection reel. Then, the plastic film is manually collected on the collection reel to complete the collection of residual film. Afterward, the stem and leaf collection blade 201 first cuts off the stems and leaves of the crops, and then the cut crop stems and leaves are collected by the stem and leaf collection mechanism 40. The conveyor belt 202 transports the crop stems and leaves to the stem and leaf collection component 203, completing the collection of crop stems and leaves. Finally, the shovel blade 401 plows out the roots from the soil. At this time, the root conveyor belt 402 transports the crop roots with soil to the root-soil separation component 403, where the soil and roots are separated. With the operation of the creeping plant clearing device, the collection of crop stems, residual film, and roots is completed, avoiding repeated collection of crop stems, residual film, and roots, reducing time loss, improving collection efficiency, and avoiding the danger of pests brought by crop stems, leaves, and roots.

[0030] In one specific embodiment, the frame 10 has a certain height, allowing it to span both sides of the ridge, thereby positioning the film collection mechanism 30, the stem and leaf collection mechanism 20, and the root collection mechanism 40 above the ridge. The frame 10 can be self-propelled or moved forward by other power sources, such as a tractor.

[0031] As the frame 10 moves forward, the stem and leaf collecting blade 201 cuts or pulls up the stems and leaves on the surface of the ridge. For example, the stem and leaf collecting blade 201 includes two symmetrically arranged blades (a pair of symmetrically arranged mower blades, with a larger distance between one end and a smaller distance between the other). The blades are V-shaped, and as the frame 10 moves forward, the stems and leaves of the crops gradually accumulate at the end with the smaller angle of the V-shaped blades, thereby pulling off the stems and leaves of the crops. Alternatively, as the frame 10 moves, the stems and leaves of the crops slowly accumulate at the end with the smaller distance, and are then cut off, separating them from the roots and stems of the crops for separate collection of the stems and leaves.

[0032] The shovel 401 can also be configured as a blade or a rake-like device. During the forward movement of the frame 10, it digs the roots of the crop from the soil surface onto the root conveyor belt 402, and then transports them into the root-soil separation box 4031 under the transport of the root conveyor belt 402.

[0033] Meanwhile, in specific settings, the stem and leaf conveyor belt 202 can be configured as two conveyor belts, wherein the surface of the conveyor belt is made uneven to increase the friction between the crop stems and leaves and the conveyor belt, and to prevent the crop stems and leaves from sliding on the conveyor belt, thus preventing the crop stems and leaves from failing to enter the crop stem and leaf collection bag along with the conveyor belt (the stem and leaf conveyor belt 202 is set at an angle, and its movement trajectory is from low to high).

[0034] Furthermore, the stem and leaf collection assembly 203 includes a bag distribution plate 2031, a drive shaft 2032, and a drive wheel 2033. The bag distribution plate 2031 is provided with a plurality of bag clamping members 2034, which are used to hold the collection bags for collecting stems and leaves. One end of the drive shaft 2032 is connected to the bag distribution plate 2031, and the other end is connected to the drive wheel 2033. The drive wheel 2033 can drive the drive shaft 2032 to rotate, and the drive shaft 2032 drives the bag clamping members 2034 to rotate.

[0035] The bag distribution plate 2031 is provided with a plurality of bag distribution plates 2031, and collection bags are held on the bag distribution plate 2031. When a collection bag is full and needs to be replaced, the bag distribution plate 2031 is driven to rotate by the drive shaft 2032 located under the bag distribution plate 2031. In use, the drive shaft 2032 can also be driven to rotate by a motor, but in this solution, the drive shaft 2032 is driven to rotate by the drive wheel 2033 to facilitate the replacement of collection bags.

[0036] In a preferred embodiment, the system further includes a gravity drive mechanism 50, which includes a support platform 501, a reciprocating screw 502, and a rotating sleeve 503. The support platform 501 is located below the bag distribution plate 2031, and the upper end of the reciprocating screw 502 is connected to the support platform 501, while the lower end extends into the rotating sleeve 503. The lower end of the rotating sleeve 503 is mounted on the frame 10 and is rotatable along the axial direction; the reciprocating screw 502 can drive the rotating sleeve 503 to rotate along the axial direction; the rotating sleeve 503 is provided with an active drive wheel 5031, the active drive wheel 5031 is connected to the rotating shaft drive wheel 2033 through a rotating connector, and the lower end face of the active drive wheel 5031 is provided with a ratchet groove, and an anti-reverse ratchet 5032 is provided in the ratchet groove; The rotating sleeve 503 also includes a one-way bearing 5033, which is disposed between the rotating sleeve 503 and the drive wheel 5031.

[0037] The reciprocating screw 502 is threaded, and the rotating sleeve 503 is also threaded. The thread in the rotating sleeve 503 matches the thread on the reciprocating screw 502. When the support platform 501 is under force, it drives the rotating screw to move up and down in height. During use, the support platform 501 does not rotate. At this time, under the action of the threads, the rotating sleeve 503 begins to rotate. It should be understood that when movement occurs, the support platform 501 only moves up and down and does not rotate, while the rotating sleeve 503 rotates. In order to ensure that the support platform 501 can rise after moving down, a fixing member can be set under the support platform 501. The fixing member retracts when the support platform 501 moves down and extends when the support platform 501 needs to rise (similar to a telescopic rod), which can also provide the upward power for the support platform 501 and ensure that the position of the support platform 501 does not shift.

[0038] Meanwhile, in actual use, the active drive wheel 5031 can only rotate in one direction and cannot rotate in the opposite direction. To avoid this situation, a one-way bearing 5033 is provided between the rotating sleeve 503 and the active drive wheel 5031. In order to better prevent the active drive wheel 5031 from rotating in reverse, an anti-reverse ratchet 5032 is provided on the lower end face of the active drive wheel 5031, which can only allow the active drive wheel 5031 to rotate in one direction. This also prevents the first pulley 2039 from rotating in the opposite direction when the rotating sleeve 503 rotates, causing the full collection bag to be replaced again.

[0039] In one specific embodiment, the bag clamping member 2034 includes a fixing ring 2035 and a pressure ring 2036. The pressure ring 2036 is disposed on the upper end face of the fixing ring 2035 and can press the open end of the collection bag between the upper end face of the fixing ring 2035 and the lower end face of the pressure ring 2036. The lower end face of the fixing ring 2035 is provided with a plurality of evenly distributed collection rods, and one end of the collection rod is hinged to an auxiliary plate 2037. The auxiliary plate 2037 can rotate from the horizontal direction to the vertical direction under the action of gravity.

[0040] In practical use, to prevent the collection bag from falling off the bag distribution plate 2031, a fixing ring 2035 and a pressure ring 2036 are provided on the bag clamping member 2034. The opening of the collection bag is positioned between the fixing ring 2035 and the pressure ring 2036. In other words, the collection bag is fixed to the fixing ring 2035. In practical use, corresponding openings can be made on the fixing ring 2035 and the pressure ring 2036. After the collection bag is placed between the fixing ring 2035 and the pressure ring 2036, a steel bar or wooden stick can be inserted into the openings in the fixing ring 2035 and the pressure ring 2036 to more firmly secure the bag. The collection bag is fixed between the fixing ring 2035 and the pressure ring 2036. To reduce the weight on the fixing ring 2035 and the pressure ring 2036, several collection rods are provided on the lower end face of the fixing ring 2035. An auxiliary plate 2037 is hinged to one end of each collection rod. The auxiliary plate 2037 changes angle under gravity. When not under gravity, the auxiliary plate 2037 supports the collection bag. When under gravity, the auxiliary plate 2037 slowly rotates from the horizontal direction to the vertical direction until it is perpendicular to the fixing ring 2035.

[0041] Furthermore, the rotating shaft drive wheel 2033 includes a fixed base 2038, a first pulley 2039, and a rotation limiting mechanism 2040. The fixed base 2038 is disposed on the frame 10, and the first pulley 2039 is sleeved on the fixed base 2038. The first pulley 2039 is connected to the active drive wheel 5031 through a rotating connector, and a trapezoidal plate 2041 is disposed on the first pulley 2039, and a guide surface 2042 is disposed on the trapezoidal plate 2041. The rotation limiting mechanism 2040 is disposed above the fixed base 2038, and the drive shaft 2032 is fixedly connected to the rotation limiting mechanism 2040.

[0042] The rotating shaft drive wheel 2033 drives the drive shaft 2032 to rotate, and the drive shaft 2032 then drives the bag clamp 2034 to rotate. When set, the fixed base 2038 does not rotate, and the first pulley 2039 sleeved on the fixed base 2038 rotates. The power for the rotation of the first pulley 2039 comes from the active drive wheel 5031. When the active drive wheel 5031 rotates, the first pulley 2039 also rotates.

[0043] Specifically, the rotation limiting mechanism 2040 further includes a synchronous pulley 2043, which is sleeved on the drive shaft 2032 and can rotate along the drive shaft 2032. A power storage component 2044 is provided between the synchronous pulley 2043 and the first pulley 2039, and a limiting groove 2045 is provided on the synchronous pulley 2043. A limiting component 2046 is sleeved on the synchronous pulley 2043, and the limiting component 2046 is in a limiting cooperation with the limiting groove 2045.

[0044] The synchronous pulley 2043 is fixedly connected to the drive shaft 2032. When the synchronous pulley 2043 rotates, it drives the drive shaft 2032 to rotate. During operation, the first pulley 2039 rotates continuously, while the drive shaft 2032 and the synchronous pulley 2043 rotate suddenly and rapidly, thereby achieving rapid bag changing. The reason for rapid bag changing is that during the rotation of the first pulley 2039, the energy storage component 2044 (such as a spring) is pulled open, and the limiting component 2046 slowly moves out of the limiting groove 2045. When the limiting component 2046 has completely moved out of the limiting groove 2045, the synchronous pulley 2043 and the drive shaft 2032 rotate rapidly by 90°, completing the bag changing.

[0045] Specifically, the limiting component 2046 includes a collar 2047, which is sleeved on the synchronous pulley 2043 and fixedly installed. The collar 2047 is provided with slots 2048, and the number of slots 2048 matches the number of bag clamping components 2034. Each slot 2048 is provided with a limiting spring 2049 and a locking block 2050. The two ends of the limiting spring 2049 are respectively connected to the inner wall of the slot 2048 and the locking block 2050. The locking block 2050 can move horizontally within the slot 2048. The lower end face of the locking block 2050 is provided with a lever 2051, which can move along the guide surface 2042, driving the locking block 2050 to move from the inside to the outside, and driving the locking block 2050 to move out of the limiting groove 2045.

[0046] In specific applications, to facilitate the rotation of the bag distribution disc 2031, a limiting component 2046 is also provided. The synchronous pulley 2043 is positioned above the first pulley 2039 and fixedly connected to the drive shaft 2032. That is, when the synchronous pulley 2043 rotates, it drives the drive shaft 2032 to rotate. To allow the bag distribution disc 2031 to rotate 90°, it cooperates with the trapezoidal plate 2041 to enable the bag distribution disc 2031 to rotate 90°. The reason for the bag distribution disc 2031 rotating 90° is that the collar 2047 has a slot 2048. When the synchronous pulley 2043 is not rotating, the fixing block is engaged in the slot 2048. When the synchronous pulley 2043 rotates, the locking block 2050 can slowly move out of the limiting groove 2045. The reason why the locking block 2050 slowly moves out of the limiting groove 2045 is as follows: At this time, the trapezoidal plate 2041 and the lever 2051 undergo relative displacement. When set, the trapezoidal plate 2041 is a right-angled trapezoid. When the locking block 2050 slowly moves out of the limiting groove 2045, the lever 2051 moves from the upper surface of the right-angled trapezoid along the inclined plane to the lower surface. According to common sense, the length of the upper surface is shorter than the length of the lower surface. At this time, during the movement of the lever 2051, the locking block 2050 is slowly moved out of the limiting groove 2045. At this time, the synchronous pulley 2043 rotates. When the locking block 2050 contacts the next limiting groove 2045 on the synchronous pulley 2043, under the action of the spring, the locking block 2050 is pushed into the next locking groove 2048, thus completing the precise return of the collection bag.

[0047] In a preferred embodiment, the rotating connector is either a chain or a belt.

[0048] Depending on the application, either a chain or a belt can be chosen.

[0049] Furthermore, the root-soil separation component 403 includes a root-soil separation box 4031, which is mounted on the frame 10. Inside the root-soil separation box 4031, a soil roller 4032, a sieve plate 4033, and a soil outlet 4034 are arranged symmetrically downwards. The soil roller 4032 is used to separate the soil from the roots, and the sieve plate 4033 is used to separate the roots and the soil. One end of the sieve plate 4033 is connected to a roller 4035.

[0050] When collecting crop roots, the roots will be covered with soil. Collecting the roots with soil would waste the collection bag and remove some soil. Therefore, a root-soil separation box 4031 is provided to remove soil from the crop roots. The soil-covered crop roots are collected in the root-soil separation box 4031 for processing. The soil-covered roots are first separated from the soil by the soil-rolling wheel 4032. After processing, the crop roots fall onto the sieve plate 4033, which has holes. The soil on the crop roots is crushed by the soil-rolling wheel 4032, turning large clumps into smaller clumps. The smaller clumps of soil fall through the holes in the sieve plate 4033 and fall back into the field through the soil outlet 4034.

[0051] The driving force for the rotation of the soil roller 4032 comes from the motor installed on the side wall of the root soil separation box 4031, or other conventional driving methods can also be selected.

[0052] In a preferred embodiment, the system further includes a sieve plate extraction component 404, which includes a rack 4041 and a winding wheel 4042. The rack 4041 is disposed on the lower end face of the support platform 501, and the winding wheel 4042 is disposed on the frame 10 via a connecting rod. The winding wheel 4042 meshes with the rack 4041 and the winding wheel 4035.

[0053] The rack 4041 is positioned below the support platform 501. When the support platform 501 moves, the gear meshing with the rack 4041 also rotates. When the gear rotates, it drives the winding wheel 4042 to rotate. When the support platform 501 moves downward, the rack 4041 moves downward, the gear rotates, and the winding wheel 4042 drives the sieve plate 4033 to move to the left, which is the same direction as the movement of the creeping plant cleaning device. Conversely, when the support platform 501 moves upward, the rack 4041 moves upward, the gear rotates, and the winding wheel 4042 drives the sieve plate 4033 to move to the right, which is the opposite direction to the movement of the creeping plant cleaning device. At this time, the sieve plate 4033 is used alternately, which facilitates the cleaning of crop roots on the sieve plate 4033.

[0054] The operating steps of the creeping plant sanitation device are as follows: The walking mechanism 101 drives the frame 10 forward, thereby causing the stem and leaf collection mechanism 20, the film collection mechanism 30, and the root collection mechanism 40 installed on the frame 10 to also move forward. During the forward movement of the frame 10, the stem and leaf collection blade 201 cuts the stems and leaves of the crops. The cut crop stems and leaves are transported by the stem and leaf conveyor belt 202 to the bag held by the bag holder 2034. As the number of stems and leaves in the bag gradually increases, the bag begins to press down on the support platform 501 under the action of gravity. The support platform 501 begins to move downward. During the downward movement of the support platform 501, the reciprocating screw 502 is driven. (The reciprocating screw 502 is fixedly connected to the lower end face of the support platform 501) also moves downward. At this time, under the action of the thread (the reciprocating screw 502 is provided with a thread that matches the thread inside the rotating sleeve 503), the rotating sleeve 503 is driven to rotate, and the rotating sleeve 503 then drives the active drive wheel 5031 to rotate; then, the active drive wheel 5031 drives the first pulley 2039 sleeved on the fixed seat 2038 (the fixed seat 2038 does not rotate) to rotate through the belt. During the rotation of the first pulley 2039, the trapezoidal plate 2041 and the energy storage element 2044 (which can be a spring) set on the first pulley 2039 will also be driven to rotate. Under the action of the energy storage component 2044, the synchronous pulley 2043 is also in a state of energy storage (it should be noted that the rotation direction of the synchronous pulley 2043 is the same as the rotation direction of the first pulley 2039). At the same time, under the action of the trapezoidal plate 2041 (which can be a right trapezoid), the lever 2051 provided on the locking block 2050 will move from the upper base to the lower base of the trapezoidal plate 2041 along the guide surface 2042 (the hypotenuse of the right trapezoid). As is common sense, the length of the upper base of the right trapezoid is less than the length of the lower base. At this time, during the movement of the lever 2051, the locking block 2050 will be driven to move into the locking slot 2048 (during this process, the locking block 2050...). 050 will compress the limiting spring 2049, causing the limiting spring 2049 to contract, thereby slowly pulling the locking block 2050 out of the limiting groove 2045. When the locking block 2050 is completely pulled out of the limiting groove 2045, the synchronous pulley 2043 rotates rapidly, which also drives the drive shaft 2032 to rotate rapidly, and the rotation angle is 90° (the reason for the rotation angle of 90° is that in this case, there are 4 limiting grooves 2045, which are evenly distributed on the synchronous pulley 2043, and there are also 4 bag clamps 2034. The setting position of the limiting grooves 2045 corresponds to the setting position of the bag clamps 2034), thus completing the bag changing operation.

[0055] After the bag changing operation is completed, the support platform 501 moves upward when it is not under pressure. A spring can be installed at the bottom of the rotating sleeve 503. When the support platform 501 is not under pressure, the spring returns to its original position, thus pushing the support platform 501 upward. During the upward movement of the support platform 501, the rotating sleeve 503 rotates. However, it should be noted that the drive wheel 5031 cannot rotate to avoid transferring the full bag back to the bottom of the stem and leaf conveyor belt. At this time, a one-way bearing 5033 is installed between the rotating sleeve 503 and the drive wheel 5031. The installation of the one-way bearing 5033 can be carried out using conventional technical means. Under the action of the one-way bearing 5033, the drive wheel 5031 can only rotate in one direction. In order to reduce the working pressure of the one-way bearing 5033 and avoid unexpected situations (damage to the one-way bearing 5033), an anti-reverse ratchet 5032 is provided on the lower end face of the drive wheel 5031. The anti-reverse ratchet 5032 is fixedly connected to the frame 10 to ensure that the drive wheel 5031 will not rotate in the opposite direction, thereby also avoiding the situation where the drive wheel 5031 drives the first pulley 2039 to rotate in the opposite direction.

[0056] Meanwhile, a root collection mechanism 40 is set up to collect crop roots. First, the shovel blade 401 extends into the soil to transfer the crop roots to the root conveyor belt 402, which then transfers them to the root-soil separation box 4031. Under the action of the soil roller 4032, the soil on the crop roots is separated from the crop roots, separating the soil from the crop roots. After separation, both the soil and crop roots fall onto the sieve plate 4033. The soil (smaller soil particles) falls through the holes in the sieve plate 4033 into the soil outlet 4034, and then falls into the farmland, while the crop roots remain on the sieve plate 4033, thus achieving the separation of soil and crop roots. Afterwards, to clean the crop roots on the sieve plate 4033, a roller 403 is set at one point of the sieve plate 4033. 5. At this time, the winding wheel 4035 meshes with the take-up wheel 4042, and the take-up wheel 4042 also meshes with the rack 4041. The rack 4041 is located on the lower end face of the support platform 501. When the support platform 501 moves down, the rack 4041 also moves down, thereby driving the take-up wheel 4042 to rotate, which in turn drives the winding wheel 4035 to rotate. During the rotation of the winding wheel 4035, the sieve plate 4033 is pulled out from the root-soil separation box 4031, thereby cleaning the crop roots on the sieve plate 4033. When setting the sieve plate 4033, two sieve plates 4033 are set. When one is moved out of the replacement separation box, the other is located inside the root-soil separation box 4031 to prevent the crop roots from falling into the soil outlet 4034 due to the absence of the sieve plate 4033, which would cause the soil outlet 4034 to become blocked.

[0057] The crop stems and leaves can be placed manually on the stem and leaf conveyor belt 202 (as an auxiliary method to better facilitate the passage of crop stems and leaves through the conveyor belt 202 into the collection bag). The crop roots can also be collected using the above method.

[0058] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.
