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

[0003] After the harvest, the stems, leaves, roots and mulch covering the ridges of crops are mostly not processed at all, and the roots that are directly returned to the field are mostly intact roots, which are not easy to ferment, not conducive to the planting and growth of the next crop, and are very prone to pests. Alternatively, the stems, leaves, rhizomes and mulch covering the ridges are manually processed. During the processing, it will be obviously found that the process of processing the stems, leaves, rhizomes and mulch is time-consuming and labor-intensive. In the process of processing the roots, when the roots are pulled out of the soil, some of the roots will remain in the soil, making it impossible to completely clean the roots, and these remaining roots are very prone to pests.

DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0028] Please see Figures 1 to 8 A creeping plant garden cleaning device comprises a frame 10, a stem and leaf collecting mechanism 20, a membrane collecting mechanism 30 and a root collecting mechanism 40, wherein the stem and leaf collecting mechanism 20, the membrane collecting mechanism 30 and the root collecting mechanism 40 are sequentially arranged on the frame 10, and a walking mechanism 101 is arranged 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 arranged on the frame 10, one end of the stem and leaf collection conveyor belt is arranged behind the stem and leaf collection knife 201, and the stem and leaf collection assembly 203 is arranged below the other end of the stem and leaf conveyor belt 202, and is used to collect the stems and leaves of crops; The film collecting mechanism 30 is used to collect ground film; The root collection mechanism 40 includes a shovel blade 401, a root conveyor belt 402 and a root-soil separation assembly 403. The shovel blade 401 is arranged on the frame 10, one end of the root conveyor belt 402 is arranged behind the shovel blade 401, and the root-soil separation assembly 403 is arranged below the other end of the root conveyor belt 402. The root-soil separation assembly 403 is used to separate the soil on the rhizome.

[0029] The walking mechanism 101 drives the frame 10 to move, and the frame 10 then drives the stem and leaf collecting mechanism 20, the film collecting mechanism 30 and the root collecting mechanism 40 to move. The creeping stem plant garden cleaning device collects the leaf stems and roots with soil of the crops respectively. When in use, the film collecting mechanism 30 first cuts the ground film covering the soil. The film collecting component can be a collecting reel and a film breaking knife arranged on both sides of the collecting reel. Then, the ground film is manually collected on the collecting reel to complete the collection of the residual film. Then, the stem and leaf collecting knife 201 first cuts the stems and leaves of the crops, and then the cut stems and leaves of the crops are collected by the stem and leaf collecting knife 201. The conveyor belt 202 transports the crops until they are in the stem and leaf collecting component 203, and the collection of the crop stems and leaves is completed. Finally, the shovel blade 401 is used to plow out the roots in the soil. At this time, the root conveyor belt 402 transports the crop roots with soil to the root-soil separation component 403, and the soil and the root system are separated in the root-soil separation component 403. With the operation of the creeping stem plant garden cleaning device, the collection of crop stems, residual film and rhizomes is completed, avoiding the repeated collection of crop stems, residual film and rhizomes, reducing time loss, improving collection efficiency, and avoiding the risk of pests caused by crop stems, leaves and roots.

[0030] In a specific embodiment, the frame 10 has a certain height and can span both sides of the ridge, so that the film collection mechanism 30, the stem and leaf collection mechanism 20, and the root collection mechanism 40 are located above the ridge. The frame 10 can move by itself or be driven by other power sources, such as a tractor.

[0031] When the frame 10 moves forward, the stem and leaf collecting knife 201 will cut off or pull up the stems on the surface of the ridge. For example, the stem and leaf collecting knife 201 includes two symmetrically arranged blades (a pair of symmetrically arranged mowing blades, and the symmetrically arranged mowing blades have a large spacing at one end and a small spacing at the other end), and the blades are in an eight-shaped shape, and during the forward movement of the frame 10, the stems and leaves of the crops will gradually accumulate at the end with a smaller angle of the eight-shaped blades, thereby pulling out the stems and leaves of the crops, or during the movement of the frame 10, the stems and leaves of the crops will slowly accumulate at the end with a smaller spacing, and then be cut off, so as to separate them from the roots and stems of the crops and collect the stems and leaves of the crops separately.

[0032] The shovel blade 401 can also be set as a blade or a device similar to a rake. During the forward movement of the frame 10, the roots of the crops are dug from under the soil surface to the root conveyor belt 402, and then transported by the root conveyor belt 402 into the root-soil separation box 4031.

[0033] At the same time, in the specific setting, the stem and leaf conveyor belt 202 can be set as two conveyor belts, wherein the surface of the conveyor belt is set to be uneven, so as to increase the friction between the crop stems and leaves and the conveyor belt, and avoid the crop stems and leaves sliding against the conveyor belt, resulting in the crop stems and leaves being unable to enter the crop stem and leaf collection bag along 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 driving shaft 2032 and a shaft driving wheel 2033. The bag distribution plate 2031 is provided with a plurality of bag clamps 2034, and the bag clamps 2034 are used to hold the collection bag for collecting stems and leaves; one end of the driving shaft 2032 is connected to the bag distribution plate 2031, and the other end is connected to the shaft driving wheel 2033. The shaft driving wheel 2033 can drive the driving shaft 2032 to rotate, and the driving shaft 2032 drives the bag clamps 2034 to rotate.

[0035] A plurality of bag distribution plates 2031 are arranged on the bag distribution plate 2031, and a collection bag is clamped 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 a driving shaft 2032 arranged under the bag distribution plate 2031. When in use, the driving shaft 2032 can also be driven to rotate by a motor. However, in the present embodiment, the shaft driving wheel 2033 is used to drive the driving shaft 2032 to rotate to facilitate the replacement of the collection bag.

[0036] In a preferred embodiment, a gravity drive mechanism 50 is further included, and the gravity drive mechanism 50 includes a load-bearing platform 501, a reciprocating screw 502 and a rotating sleeve 503. The load-bearing platform 501 is arranged below the bag distribution plate 2031, and the upper end of the reciprocating screw 502 is connected to the load-bearing platform 501, and the lower end extends into the rotating sleeve 503; The lower end of the rotating sleeve 503 is arranged on the frame 10 and can rotate in the axial direction; the reciprocating screw 502 can drive the rotating sleeve 503 to rotate in the axial direction; an active driving wheel 5031 is arranged on the rotating sleeve 503, and the active driving wheel 5031 is connected to the rotating shaft driving wheel 2033 through a rotating connecting piece, and a ratchet groove is arranged on the lower end surface of the active driving wheel 5031, and an anti-reverse ratchet 5032 is arranged in the ratchet groove; The rotating sleeve 503 further includes a one-way bearing 5033 , and the one-way bearing 5033 is disposed between the rotating sleeve 503 and the active driving wheel 5031 .

[0037] The reciprocating screw 502 is provided with a thread, and the rotating sleeve 503 is also provided with a thread. The thread in the rotating sleeve 503 matches the thread on the reciprocating screw 502. When the load-bearing platform 501 is subjected to force, it drives the rotating screw to move up and down in the height direction. When in use, the load-bearing platform 501 does not rotate. At this time, under the action of the thread, the rotating sleeve 503 begins to rotate. It should be understood that when moving, the load-bearing platform 501 only moves up and down and does not rotate, while the rotating sleeve 503 rotates. In order to ensure that the load-bearing platform 501 can rise after moving down, the fixing part can be arranged under the load-bearing platform 501. The fixing part is retracted when the load-bearing platform 501 moves down, and is unfolded (similar to a telescopic rod) when the load-bearing platform 501 needs to rise. It can also provide the load-bearing platform 501 with rising power, and at the same time ensure that the position of the load-bearing platform 501 is not offset.

[0038] At the same time, during specific use, the active driving wheel 5031 can only rotate in one direction and cannot rotate in the opposite direction. In order to avoid this situation, a one-way bearing 5033 is arranged between the rotating sleeve 503 and the active driving wheel 5031, and in order to better prevent the active driving wheel 5031 from reversing, the anti-reversal ratchet 5032 is arranged on the lower end surface of the active driving wheel 5031, so that the active driving wheel 5031 can only rotate in one direction. This also prevents the rotating sleeve 503 from rotating in the opposite direction, driving the first pulley 2039 to rotate in the opposite direction, causing the full collection bag to be replaced again.

[0039] In a specific embodiment, the bag body clamp 2034 includes a fixing ring 2035 and a pressure ring 2036, and the pressure ring 2036 is arranged on the upper end surface of the fixing ring 2035, and can press the open end of the collecting bag between the upper end surface of the fixing ring 2035 and the lower end surface of the pressure ring 2036, and the lower end surface of the fixing ring 2035 is provided with a plurality of evenly distributed collecting rods, and one end of the collecting rod is hingedly provided with an auxiliary plate 2037, and the auxiliary plate 2037 can be rotated from a horizontal direction to a vertical direction under the action of gravity.

[0040] During specific use, in order to prevent the collecting bag from falling off the bag distribution plate 2031, the fixing ring 2035 and the pressing ring 2036 are arranged on the bag clamp 2034, and the opening of the collecting bag is arranged between the fixing ring 2035 and the pressing ring 2036. In other words, the collecting bag is fixed on the fixing ring 2035. During specific use, corresponding openings can be opened on the fixing ring 2035 and the pressing ring 2036. After the collecting bag is placed between the fixing ring 2035 and the pressing ring 2036, a steel bar or a wooden stick is inserted into the openings opened by the fixing ring 2035 and the pressing ring 2036 to more firmly hold the collecting bag. The collecting bag is fixed between the fixing ring 2035 and the pressing ring 2036; at the same time, in order to reduce the gravity exerted on the fixing ring 2035 and the pressing ring 2036, a plurality of collecting rods are arranged on the lower end face of the fixing ring 2035, and an auxiliary plate 2037 is hingedly arranged at one end of the collecting rod. The angle of the auxiliary plate 2037 will also change under the action of gravity. When the auxiliary plate 2037 is not subjected to gravity, the auxiliary plate 2037 will support the collecting bag. When the auxiliary plate 2037 is subjected to gravity, the auxiliary plate 2037 will slowly rotate from the horizontal direction to the vertical direction until it is perpendicular to the fixing ring 2035.

[0041] Furthermore, the rotating shaft driving wheel 2033 includes a fixed seat 2038, a first pulley 2039 and a rotation limiting mechanism 2040, the fixed seat 2038 is arranged on the frame 10, the first pulley 2039 is sleeved on the fixed seat 2038, the first pulley 2039 is connected to the active driving wheel 5031 through a rotating connecting member, and a trapezoidal plate 2041 is arranged on the first pulley 2039, and a guide surface 2042 is arranged on the trapezoidal plate 2041; the rotation limiting mechanism 2040 is arranged above the fixed seat 2038, and the driving shaft 2032 is fixedly connected to the rotation limiting mechanism 2040.

[0042] The shaft driving wheel 2033 drives the driving shaft 2032 to rotate, and the driving shaft 2032 in turn drives the bag body clamping part 2034 to rotate. When setting, the fixed seat 2038 does not rotate, and the first pulley 2039 mounted on the fixed seat 2038 rotates. The power for the rotation of the first pulley 2039 comes from the active driving wheel 5031. When the active driving wheel 5031 rotates, the first pulley 2039 also rotates accordingly.

[0043] Specifically, the rotation limiting mechanism 2040 also includes a synchronous pulley 2043, which is sleeved on the driving shaft 2032 and can rotate along the driving shaft 2032. A force storage member 2044 is arranged between the synchronous pulley 2043 and the first pulley 2039, and a limiting groove 2045 is arranged on the synchronous pulley 2043; a limiting component 2046 is sleeved on the synchronous pulley 2043, and the limiting component 2046 cooperates with the limiting groove 2045 for limiting.

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

[0045] Specifically, the limiting assembly 2046 includes a ring 2047, which is sleeved on the synchronous pulley 2043 and fixedly arranged. A slot 2048 is arranged on the ring 2047, and the number of the slots 2048 matches the number of the bag body clamping member 2034. A limiting spring 2049 and a block 2050 are arranged in the slot 2048. The two ends of the limiting spring 2049 are respectively connected to the inner wall of the slot 2048 and the block 2050, and the block 2050 can move horizontally in the slot 2048. A lever 2051 is arranged on the lower end surface of the block 2050, and the lever 2051 can move along the guide surface 2042 to drive the block 2050 to move from the inside to the outside, and drive the block 2050 to move out of the limiting slot 2045.

[0046] In a specific usage situation, in order to facilitate the rotation of the bag distribution disk 2031, a limiting component 2046 is further provided, and the synchronous pulley 2043 is provided above the first pulley 2039 and fixedly connected to the driving shaft 2032, that is, when the synchronous pulley 2043 rotates, it drives the driving shaft 2032 to rotate, and in order to make the bag distribution disk 2031 rotate 90º, it is used in conjunction with the trapezoidal plate 2041 to enable the bag distribution disk 2031 to rotate 90º; the reason why the bag distribution disk 2031 rotates 90º is that the collar 2047 is provided with a slot 2048, and when the synchronous pulley 2043 does not rotate, the fixed block is clamped in the slot 2048, and when the synchronous pulley 2043 rotates, the clamping block 2050 can be slowly moved out of the limiting slot 2045; the The reason why the block 2050 is slowly moved out of the limit groove 2045: at this time, the trapezoidal plate 2041 and the lever 2051 are relatively displaced. When set, the trapezoidal plate 2041 is a right-angled trapezoid. When the block 2050 is slowly moved out of the limit groove 2045, the lever 2051 moves from the upper surface of the right-angled trapezoid along the inclined surface to the lower bottom surface. According to common sense, the length of the upper bottom is shorter than the length of the lower bottom. At this time, during the movement of the lever 2051, the block 2050 is slowly moved out of the limit groove 2045. At this time, the synchronous pulley 2043 rotates. When the block 2050 contacts the next limit groove 2045 on the synchronous pulley 2043, under the action of the spring, the block 2050 is pushed into the next slot 2048, thereby completing the precise bag return work of the collection bag.

[0047] In a preferred embodiment, the rotating connecting member is a chain or a belt.

[0048] Depending on the application, you can choose a chain or a belt.

[0049] Furthermore, the root-soil separation assembly 403 includes a root-soil separation box 4031, which is arranged on the frame 10, and the root-soil separation box 4031 is provided with symmetrically arranged soil rolling wheels 4032, sieve plates 4033 and soil outlets 4034 in sequence downwardly, the soil rolling wheels 4032 are used to separate the soil on the roots, the sieve plates 4033 are used to separate the roots and the soil, and one end of the sieve plates 4033 is connected to a reel 4035.

[0050] When collecting the roots of crops, the roots of the crops will carry soil. If the roots with soil are collected together, it will not only lead to a waste of the collection bag, but also take away some soil. Therefore, the root-soil separation box 4031 is set. The root-soil separation box 4031 is used to remove the soil on the roots of crops. The crop roots without soil are collected in the root-soil separation box 4031 for processing. The roots with soil first pass through the rolling wheel 4032 to separate the roots from the soil. After the roots and stems of the crops with soil are processed, the roots and stems of the crops fall onto the sieve plate 4033, and the sieve plate 4033 is provided with holes. After the soil on the roots and stems of the crops is crushed by the rolling wheel 4032, it changes from large pieces to small pieces. The small pieces of soil will fall along the holes on the sieve plate 4033 to the bottom of the sieve plate 4033 and fall back to the farmland from the outlet 4034.

[0051] The driving force for the rotation of the soil-milling wheel 4032 comes from a motor arranged 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, it also includes a screen plate extraction component 404, which includes a rack 4041 and a winding wheel 4042, wherein the rack 4041 is arranged on the lower end surface of the load-bearing platform 501, and the winding wheel 4042 is arranged on the frame 10 through a connecting rod, and the winding wheel 4042 is meshed with the rack 4041 and the winding wheel 4035.

[0053] The rack 4041 is arranged below the load-bearing platform 501. When the load-bearing 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 load-bearing 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 consistent with the direction of movement of the creeping stem plant cleaning device. Conversely, when the load-bearing 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 opposite to the direction of movement of the creeping stem plant cleaning device. At this time, the sieve plates 4033 are used alternately to facilitate cleaning the crop roots on the sieve plates 4033.

[0054] The steps of using the creeping stem plant garden cleaning device are as follows: the walking mechanism 101 drives the frame 10 to move forward, so that the stem and leaf collecting mechanism 20, the membrane collecting mechanism 30 and the root collecting mechanism 40 arranged on the frame 10 also move forward. During the movement of the frame 10, the stem and leaf collecting knife 201 cuts off the stems and leaves of the crops, and the cut stems and leaves of the crops are transported by the stem and leaf conveyor belt 202 to the bag body clamped on the bag body clamp 2034. As the number of stems and leaves in the bag body gradually increases, the bag body begins to press down the load-bearing platform 501 under the action of gravity, and the load-bearing platform 501 begins to move downward. During the downward movement of the load-bearing platform 501, the reciprocating screw 502 is driven. (the reciprocating screw 502 is fixedly connected to the lower end surface of the load-bearing platform 501) also moves downward, and at this time, under the action of the thread (the reciprocating screw 502 is provided with a thread matching the rotating sleeve 503), the rotating sleeve 503 is driven to rotate, and the rotating sleeve 503 then drives the active driving wheel 5031 to rotate; afterwards, the active driving wheel 5031 drives the first pulley 2039 mounted on the fixed seat 2038 (the fixed seat 2038 does not rotate) to rotate through the belt, and during the rotation of the first pulley 2039, the trapezoidal plate 2041 and the force storage member 2044 (which can be a spring) arranged on the first pulley 2039 are also driven to rotate, and then Under the action of the force storage member 2044, the synchronous pulley 2043 is also in a state of storing force (it should be clear that the rotation direction of the synchronous pulley 2043 is consistent with 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-angled trapezoid), the lever 2051 provided on the block 2050 will move from the upper bottom to the lower bottom of the trapezoidal plate 2041 along the guide surface 2042 (the hypotenuse of the right-angled trapezoid). It is known from common sense that the length of the upper bottom of the right-angled trapezoid is shorter than the length of the lower bottom. At this time, during the movement of the lever 2051, the block 2050 will be driven to move into the slot 2048 (in this process, the block 2 050 will compress the limit spring 2049 and shrink the limit spring 2049), so that the block 2050 is slowly pulled out of the limit slot 2045. When the block 2050 is completely pulled out of the limit slot 2045, the synchronous pulley 2043 rotates rapidly, and also drives the driving shaft 2032 to rotate rapidly, and the rotation angle is 90° (the reason for the rotation angle of 90°: in this case, the limit slots 2045 are set to 4 and are evenly distributed on the synchronous pulley 2043. There are also 4 bag body clamps 2034, and the setting position of the limit slots 2045 corresponds to the bag body clamp 2034), and the bag changing operation is completed.

[0055] When the bag changing operation is completed, the load-bearing platform 501 moves up when it is not under pressure. A spring can be set at the bottom of the rotating sleeve 503. When the load-bearing platform 501 is not under pressure, the spring resets to push the load-bearing platform 501 up. During the upward movement of the load-bearing platform 501, the rotating sleeve 503 rotates in the direction. However, it should be noted that the active driving wheel 5031 cannot rotate in the direction to avoid changing the filled bag back to the bottom of the stem and leaf conveyor belt again. At this time, a one-way bearing 5033 ( The one-way bearing 5033 can be installed by conventional technical means. Under the action of the one-way bearing 5033, the active 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 surface of the active drive wheel 5031, and the anti-reverse ratchet 5032 is fixedly connected to the frame 10 to ensure that the active drive wheel 5031 will not rotate in the reverse direction, thereby avoiding the active drive wheel 5031 from driving the first pulley 2039 to rotate in the reverse direction.

[0056] At the same time, in order to collect the rhizomes of crops, a root collection mechanism 40 is set up. First, the shovel blade 401 extends into the soil to transfer the roots of crops in the soil to the root conveyor belt 402, and then the root conveyor belt 402 transfers them to the root-soil separation box 4031. Under the action of the soil roller 4032, the soil on the root system of crops is separated from the root system of crops, and the soil and the root system of crops are separated. Then, the separated soil and the root system of crops both fall onto the sieve plate 4033, and the soil falls into the discharging port 4034 from the holes of the sieve plate 4033 (the soil particles are relatively small), and then falls into the farmland through the discharging port 4034, while the root system of crops remains on the sieve plate 4033, thereby achieving the separation of soil and the root system of crops. Then, in order to clean the root system of crops on the sieve plate 4033, a reel 403 is set at one point of the sieve plate 4033. 5. At this time, the reel 4035 is meshed with the take-up wheel 4042, and the take-up wheel 4042 is also meshed with the rack 4041. The rack 4041 is arranged on the lower end surface of the load-bearing platform 501. When the load-bearing platform 501 moves downward, the rack 4041 also moves downward, thereby driving the take-up wheel 4042 to rotate, thereby driving the reel 4035 to rotate. During the rotation of the reel 4035, the sieve plate 4033 is drawn out of the root-soil separation box 4031, so as to clean the crop roots on the sieve plate 4033. When the sieve plate 4033 is arranged, two sieve plates 4033 are arranged. When one is moved outside the replacement separation box, the other is located in the root-soil separation box 4031, so as to prevent the crop roots from falling into the soil outlet 4034 due to the absence of the sieve plate 4033, thereby blocking the soil outlet 4034.

[0057] Wherein: the stems and leaves of the crops can be placed on the stem and leaf conveyor belt 202 by manpower (auxiliary effect, which can better enable the stems and leaves of the crops to enter the collection bag through the stem and leaf conveyor belt 202, and the collection method of the roots of the crops can also be carried out by the above method.

[0058] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
