Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural machinery technology. More particularly, the present application relates to a low-position folding mulberry branch and leaf non-destructive cutting device. BACKGROUND

[0002] There are two ways of mulberry silkworm breeding, namely, leaf breeding and strip mulberry breeding. The strip mulberry cutting operation is an essential link in silkworm breeding. At present, the cutting operation mainly relies on manual sickle harvesting. It takes 3-4 hours for a breeder to harvest one mu of mulberry land, and a large amount of time is needed for subsequent picking and returning. The time-consuming and labor-intensive cutting operation makes breeders feel bitter. At present, there are a small number of mulberry branch harvesting devices, but most of the mulberry fields are distributed in mountainous and hilly areas, and the terrain of mulberry planting is various. The existing mulberry branch harvesting devices are too large to fully adapt to the terrain, and the structure is imperfect, which often damages the mulberry leaves, especially the tender leaves, during the cutting process. The breakage rate of mulberry branches reaches 1.23% during the tearing process of sickle cutting, and the breakage rate of mulberry branches of other cutting devices is more than 25%. In addition, machine oil and grease pollute the mulberry leaves, causing the harvested mulberry leaves to deteriorate and the polluted mulberry leaves to cause diseases in silkworms. In order to change the breeding mode with high labor demand and low working efficiency, and to avoid damage to mulberry leaves during cutting, the technical team of the company independently develops a strip mulberry cutting device suitable for various terrains and avoids damage to mulberry leaves.

[0028] Preferably, the walking vehicle is any one of a handcart, a tracked chassis or a wheeled chassis.

[0029] The present application at least has the following beneficial effects:

[0030] First, due to the growth characteristics of mulberry branches, the branches are extremely numerous, and even some branches grow close to the ground. In order to be able to harvest cleanly at one time, it is necessary to find a way to straighten the small branches and the branches growing close to the ground and feed them into the upper and lower branch clamping rollers. The present application pre-concentrates through the arrangement of the supporting structure before harvesting, and under the transmission of the right-angle gearbox, the supporting pulley and the rubber toothed belt are driven to rotate. The opposite side of the pair of rubber toothed belts moves from the front end to the rear end and from the lower end to the upper end at the same time. The rubber long teeth hook up the mulberry branches growing close to the ground and feed them into the upper and lower branch clamping rollers, the front end branch clamping pulley and the branch clamping belt at the rear end.

[0031] Second, the supporting structure, the upper and lower branch clamping rollers, the front end branch clamping pulley, the branch clamping belt, the rear end branch clamping pulley and the cutting cutter are simultaneously linked and operated by starting the rotating power structure. The mulberry branches are first folded at a low position by the supporting structure, then clamped by the upper and lower branch clamping rollers, and then fed into the cutting cutter by the branch clamping belt. After the mulberry branches are cut, they are connected without damage and conveyed to the rear end by the branch clamping belt. As the walking vehicle moves forward, the mulberry branches on the ridge are successively harvested, which can significantly improve the mulberry branch harvesting effect and at the same time reduce the damage to the branches and tender leaves.

[0032] Third, the height of the herb mulberry that usually reaches the harvesting standard is about 1 meter. At this time, the branches and leaves are relatively tender and easy to be squeezed or scratched by external force. The water in the leaves is lost quickly, which affects the storage time of the leaves. By arranging the soft rubber sleeve, the mulberry branches are clamped by the soft rubber sleeve, which achieves the effect of not damaging the branches and tender leaves. Specifically, the soft rubber sleeve can be made of soft rubber material or soft silicone material.

It does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0050] like Figures 1-13 As shown, the present invention provides a low-position closing type non-destructive mulberry branch and leaf felling device, comprising:

[0051] The traveling vehicle 1; specifically, the traveling vehicle 1 can be a handcart, a tracked chassis, or a wheeled chassis, etc.

[0052] The harvesting module 2 is detachably arranged on the walking vehicle; in order to solve the problems of mechanical adaptation to multiple terrains, portability, flexibility and single-person operation, a rotating power structure 100, a bottom gear box 12, a cutting cutter 17, a branch clamping gear box 18, a guide plate 25 and the like are integrated to form a modularization. The user can select a suitable traveling structure (walking vehicle) according to the own mulberry field, and assemble a low-position folding mulberry branch and leaf non-destructive cutting device.

[0053] The harvesting module 2 comprises:

[0054] The rotating power structure 100 has a rotating output shaft for outputting rotating kinetic energy; specifically, the rotating power structure can select a charged storage battery as a power supply to power a motor, and the output shaft of the motor is the rotating output shaft. The output shaft of the diesel engine 49 is the rotating output shaft. Specifically, a safety protection cover 11 is sleeved outside the rotating output shaft, which is used to protect the user and avoid hurting the user when the output shaft rotates.

[0055] The bottom gear box 12 is detachably arranged on the walking vehicle, and the bottom gear box has a main input shaft 13, a pair of vertically upward and symmetrically arranged third output shafts 28, a pair of vertically upward and symmetrically arranged first output shafts 14, a pair of second output shafts 15 coaxial with the first output shafts 14 and arranged downward from the rear end to the front end of the walking vehicle. A mulberry passing gap 16 is formed between the pair of first output shafts. The symmetry axes of the pair of first output shafts and the pair of second output shafts 15 are parallel to the radial direction from the front end to the rear end. The rotating power structure is arranged on the bottom gear box, and the rotating output shaft is coaxially fixed with the main input shaft 13. In order to facilitate the description of the structure, the walking vehicle is taken as the reference, the walking vehicle head is the front end, and the tail is the rear end. The rotating kinetic energy provided by the rotating power structure is converted and transmitted through the bottom gear box. According to the actual needs, the transmission ratio of the bottom gear box is set, so as to realize the rotating output of multiple different speeds and directions. Specifically, the bottom gear box can be detachably fixed with the walking vehicle by means of bolts and nuts.

[0056] A pair of cutting cutters 17, the cutter shafts of the pair of cutting cutters are respectively coaxially fixed with the pair of second output shafts, located at the front end of the walking vehicle and below the bottom gear box; the second output shaft can drive the cutting cutter to rotate towards each other, thereby realizing the cutting of the mulberry branches. Specifically, the cutting cutter can select a disc cutter, and a pair of disc cutters are arranged in parallel and engaged, which can realize fast cutting of the mulberry branches in combination with the rotating speed of the cutter shaft, and the incision is smooth.

[0057] A pair of branch clamping gear boxes 18, a pair of branch clamping gear boxes have a branch clamping input shaft 19 fixed coaxially with the first output shaft and an axially inclined branch clamping output shaft 20, wherein the upper end of the branch clamping output shaft 20 is inclined to the front end of the walking vehicle, and the branch clamping output shaft is sequentially coaxially fixed with a lower branch clamping roller 21, a front end branch clamping pulley 22 and an upper branch clamping roller 23 from bottom to top, the outer side wall of the lower branch clamping roller 21 and the upper branch clamping roller 23 is coaxially sleeved with a soft rubber sleeve 24, a pair of soft rubber sleeves 24 are gap arranged to form a branch clamping gap, and the branch clamping gap is located above the cutting place of the cutting cutter. When the mulberry branch harvesting operation is performed, the walking vehicle moves forward at a certain speed, and the upper end of the branch clamping output shaft is inclined to the front end of the walking vehicle, which is beneficial to the upper branch clamping roller to clamp the mulberry branch first and feed the mulberry branch backward along the rotation direction of the pair of upper branch clamping rollers, and the lower part of the clamped mulberry branch can quickly reach the mulberry passing gap 16, thereby reaching the cutting place of the cutting cutter, and the lower branch clamping roller can also clamp some short and small branches of the mulberry branch, which can achieve the technical effect of clean mulberry branch harvesting. The branch clamping belt 27 (structure described in the latter paragraph) is arranged between the upper branch clamping roller and the lower branch clamping roller, which can clamp the mulberry branch without damage and reach the cutting place of the cutting cutter. Under the clamping action of the branch clamping belt 27, the mulberry branch can stand stably, which is beneficial to the accurate cutting of the cutting cutter and the smoothness of the cutting. The height of the herb mulberry that meets the harvesting standard is about 1 meter, at this time, the branches and leaves are relatively tender and easy to be squeezed or scratched by external force, the water in the leaves is lost quickly, and the storage time of the leaves is shortened. By arranging the soft rubber sleeve, the mulberry branch is clamped by the soft rubber sleeve, which does not damage the branches and tender leaves. Specifically, the soft rubber sleeve can be made of soft rubber material or soft silica gel material.

[0058] A pair of guide plates 25 are arranged above the bottom gear box through a branch guiding support, the front end of the guide plate is arranged close to the front end branch clamping pulley 22, the rear end of the guide plate is arranged with a rear end branch clamping pulley 26 which is axially parallel to the axial direction of the front end branch clamping pulley, the front end branch clamping pulley and the corresponding rear end branch clamping pulley 26 are arranged with a branch clamping belt in tension, a plurality of guide pulleys 55 are arranged axially parallel between the front end branch clamping pulley and the rear end branch clamping pulley, the branch clamping belt is arranged in tension on the plurality of guide pulleys 55, and the guide pulleys are located on one side of the pair of front end branch clamping pulleys. A pair of branch clamping belts are arranged to form a branch conveying channel. The mulberry branch cut by the cutting cutter moves to the rear end along the branch conveying channel under the action of the pair of branch clamping belts, and the branch clamping belt is also flexible and does not damage the branches and tender leaves. The guide pulleys arranged on the guide plate are beneficial to keeping the front end branch clamping pulley and the rear end pulley parallel, not loose and not off track, and clamping the mulberry branch in the branch conveying channel at any time;

[0059] The lifting structure 200 comprises:

[0060] A pair of right-angle gearboxes 29 are fixed to the front ends of the pair of branch clamping gearboxes respectively through a pair of straw supporting brackets, and the input shafts of the pair of right-angle gearboxes are connected with the pair of third output shafts 28 through a pair of flexible shafts 30. The rotation of the third output shafts can be transmitted to the right-angle gearboxes stably and remotely through the flexible shafts 30, which occupies less space than other rotation transmission structures and is beneficial to reducing the volume and weight of the low-position folding mulberry branch and leaf nondestructive cutting device as a whole.

[0061] A pair of straw supporting plates 31 are fixed to the front ends of the pair of straw supporting brackets respectively, and a pair of straw supporting pulleys 32 are arranged on the straw supporting plates. The axle of one of the straw supporting pulleys 32 is coaxially fixed with the output shaft of the right-angle gearbox, and a rubber toothed belt 33 is arranged on the pair of straw supporting pulleys in tension. The lower end of the straw supporting plate is inclined towards the front end, and the outer rubber long teeth 34 of the rubber toothed belt 33 extend outside the straw supporting plate. Due to the growth characteristics of the mulberry branches, there are many branches, and even some branches grow close to the ground. In order to cut all the branches at one time, the small branches and the branches growing close to the ground need to be straightened and fed into the upper and lower branch clamping rollers. Therefore, the straw supporting structure 200 is arranged to collect the branches before cutting. Under the transmission of the right-angle gearbox, the straw supporting pulley and the rubber toothed belt are driven to rotate. The opposite sides of the pair of rubber toothed belts move from the front end to the rear end and from the lower end to the upper end at the same time. The rubber long teeth 34 hook up the mulberry branches growing close to the ground and feed them into the upper and lower branch clamping rollers and the front end branch clamping pulley located behind. The rubber long teeth are also flexible and will not damage the branches and tender leaves.

[0062] A pair of branch gathering plates 35 are fixed to the outer sides of the pair of straw supporting plates near the lower ends of the straw supporting plates respectively, and the outer sides of the other ends of the pair of branch gathering plates extend freely. The branch gathering plates are arc-shaped and extend towards the rear end from the outer sides. Since the mulberry branches have a certain width, the pair of branch gathering plates can gather the mulberry branches in the whole row to the pair of rubber toothed belts, thereby significantly improving the mulberry branch cutting effect.

[0063] In the above technical scheme, when the mulberry branch harvesting function is performed, the walking vehicle moves to align the upper branch clamping roller with the row ridge to be harvested, the rotation power structure is started, the supporting structure, the upper branch clamping roller, the lower branch clamping roller, the front end branch clamping belt pulley, the branch clamping belt, the rear end branch clamping belt pulley and the cutting disc are simultaneously linked and operated, and the pair of branch gathering plates gather the mulberry branches on the entire row ridge between the pair of rubber tooth belts. At the same time, the rubber long teeth hook the mulberry branches growing on the ground and feed the mulberry branches to the upper branch clamping roller, the lower branch clamping roller and the front end branch clamping belt pulley located at the rear end. The mulberry branches are clamped by the upper branch clamping roller and the lower branch clamping roller, then connected and fed to the cutting disc cutting position by the branch clamping belt located between the upper branch clamping roller and the lower branch clamping roller, and then transported to the rear end after cutting. With the movement of the walking vehicle forward, the mulberry branches on the row ridge are successively harvested, which can significantly improve the mulberry branch harvesting effect and reduce the damage to the branches and tender leaves.

[0064] In another technical scheme, the guide plates are arranged in a double-plate spaced-apart manner, and the middle space is used to fix the rear end branch clamping belt pulley, which can reduce the winding of the mulberry branches into the branch clamping belt during the conveying process, thereby reducing the damage to the branches and tender leaves.

[0065] In another technical scheme, a plurality of guide belt pulleys on the pair of branch clamping belts are arranged in an alternating manner, forming a triangular wave shape, so that the pair of branch clamping belts form a tight and stable clamping force, which is beneficial to the stable conveying of the mulberry branches.

[0066] In another technical scheme, the rear end branch clamping belt pulley is arranged in a position-adjustable structure. Specifically, the rotating shaft of the rear end branch clamping belt pulley is rotatably arranged on the upper support plate 56 and the lower support plate 58 at the upper end and the lower end respectively. The upper end of the upper support plate 56 is provided with a supporting rod 57, and the upper end of the lower support plate 58 is provided with an abutting plate 59. The front end of the guide plate is provided with a supporting plate 60, and the supporting plate 60 is provided with a clamping hole. The supporting rod 57 is slidably clamped in the clamping hole. A threaded cylinder 61 is installed on the lower surface of the guide plate in parallel to the conveying direction of the mulberry branches. A threaded rod 62 is screwed on the threaded cylinder 61, and the rear end of the threaded rod 62 abuts against the abutting plate 59. By rotating the threaded rod, the distance between the rear end branch clamping belt pulley and the front end belt pulley can be adjusted, thereby adjusting the tightness of the branch clamping belt.

[0067] In another technical scheme, the supporting plates of the supporting structure are arranged in a double-plate spaced-apart manner, and the middle space is used to fix a pair of supporting belt pulleys, which can reduce the winding of the mulberry branches into the branch clamping belt during the feeding process to the rear end, and the damage to the branches and tender leaves between the supporting belt pulley and the rubber tooth belt.

[0068] In another technical solution, a pair of anti-tangling protective covers 36 are also included. The pair of anti-tangling protective covers 36 are suspended above a pair of upper branch clamping rollers by a pair of cover plate supports, and the front end of the anti-tangling protective cover extends close to the front end of the supporting plate, and the rear end of the anti-tangling protective cover extends close to the guide plate. Specifically, the shape of the anti-tangling protective cover is set according to the size of the upper and lower branch clamping rollers.

[0069] In the above technical solution, in order to prevent the mulberry branches from being scratched by the front branch clamping belt or from getting tangled with other components and losing leaves during the movement of the branches, the above-mentioned anti-tangling protective cover is set up to achieve the effect of not damaging the branches and tender leaves.

[0070] In another technical solution, a bottom anti-tangling plate 37 is also included. This plate is fixed above the bottom gearbox by a lifting bracket and located below the guide plate. The front end of the bottom anti-tangling plate 37 is positioned near the front branch-clamping pulley, and the rear end is axially horizontally cylindrical and positioned near the rear branch-clamping pulley. The cut mulberry branches are approximately 1 meter long. Therefore, when the branches are conveyed backward, they are tilted backward with the branch tips pointing upwards. The cylindrical rear end of the lifting plate creates an upward-convex, arc-shaped slope, ensuring the branch tips are higher than the cut portion. This lifts the branch tips upwards, allowing the branch-clamping belt to act primarily on the thicker parts of the branch base, facilitating backward conveying and reducing damage to branches and leaves. It also prevents branches and leaves from tangling, ensuring smooth backward conveying of the mulberry branches.

[0071] In the above technical solution, since a rotating power structure and various fixed components are installed between the bottom gearbox and the guide plate, many gaps and sharp corners are formed, which may damage the branches and tender leaves or the sharp corners may hook the mulberry branches, causing blockage of the branch feeding channel and hindering the backward transport of mulberry branches. Therefore, a bottom anti-tangling plate is set up, located directly below the guide plate, to support the cut mulberry branches, reduce damage to the branches and tender leaves, and smoothly transport the mulberry branches backward.

[0072] In another technical solution, an automatic adjustment structure 300 for the clamping gearbox is also included, wherein the rear end of one clamping gearbox is coaxially rotatably connected to the first output shaft. Specifically, a bearing is coaxially sleeved on the first output shaft, and the clamping gearbox is provided with a bearing seat. The outer side wall of the bearing is coaxially fixed to the inner side wall of the bearing seat, thereby realizing the coaxial rotatable connection between the clamping gearbox and the first output shaft. Thus, one clamping gearbox can rotate relative to the first output shaft.

[0073] The automatic branch adjustment structure 300 includes:

[0074] The I-shaped frame 38 has its upper and lower ends rotatably connected to the upper and lower parts of the corresponding clamping output shaft, and is located outside the clamping gearbox; the I-shaped frame 38 does not affect the rotation of the clamping output shaft.

[0075] a tensioning support 39, which is arranged on the bottom gear box and is located on the same side of the branch clamping gear box;
