[0025] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The present embodiment provides a plant cutting device. It is worth noting that the present invention uses leek harvesting as an example to describe the plant cutting device. It does not only include harvesting leek, but can also be used for pruning other crops, vegetables or weeds.

[0027] like Figure 1 As shown, the vehicle comprises a frame 1, wherein the frame 1 is provided with a shearing component 11, a transfer component 12 and a storage box 13 for storing leeks in sequence from the head to the tail, and running wheels and a motor for driving the running wheels to move are installed on the frame 1.

[0028] Through the above arrangement, the motor is used to drive the running wheels to rotate, thereby realizing the movement of the frame 1, and the shearing component 11 is used to shear the leeks, and then the sheared leeks are put into the transfer component 12, and finally the leeks in the transfer component 12 are dumped into the storage box 13 to realize the recycling of leeks.

[0029] Specifically, in order to be able to cut the leek, in this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the shearing component 11 includes a clamping mechanism 111, a shearing mechanism 112 and a flipping mechanism 113 for driving the shearing component 11 to flip as a whole, wherein the clamping mechanism 111 is used to clamp and fix the leeks, the shearing mechanism 112 separates the leek stems from the leek roots, and the flipping mechanism 113 flips the shearing component 11 at an angle, thereby transporting the sheared leeks to the transfer component 12.

[0030] In order to achieve the clamping of leeks, in this embodiment, Figure 2 and Figure 5 As shown, the shearing component 11 also includes a positioning plate 110, wherein the positioning plate 110 is provided with an avoidance groove for the leeks to extend upward, and the clamping mechanism 111 includes a first motor 1111, a first screw rod 1112, two first screw rod nuts 1113, a first clamping plate 1114 and a second clamping plate 1115, wherein the first screw rod 1112 is arranged along the width direction of the frame 1, and the first screw rod 1112 is rotatably connected to the positioning plate 110 through a support seat, the first motor 1111 is fixedly mounted on the positioning plate 110, and the output shaft of the first motor 1111 is fixedly connected to the first screw rod 1112, and the first screw rod 1112 has two threaded sections with opposite rotation directions, wherein the two first screw rod nuts 1113 are respectively threadedly connected to one of the threaded sections, and the first clamping plate 1114 and the second clamping plate 1115 are respectively fixedly connected to the first screw rod nut 1113.

[0031] Through the above arrangement, the first motor 1111 is used to drive the first screw rod 1112 to rotate, which can drive the two first screw rod nuts 1113 to move toward or away from each other, and can drive the first clamping plate 1114 and the second clamping plate 1115 to clamp the leek, or release the clamping of the leek, so as to fix the leek and facilitate the cutting of the leek.

[0032] In order to prevent the first clamping plate 1114 and the second clamping plate 1115 from rotating around the axis of the first screw rod 1112, in this embodiment, Figure 2 and Figure 5 As shown, it also includes a second positioning seat 1134 fixedly mounted on the positioning plate 110, wherein a rotating shaft 1132 arranged parallel to the first screw rod 1112 is fixedly provided on the second positioning seat 1134, wherein the first screw rod nut 1113 is sleeved on the rotating shaft 1132 and is slidably connected to the rotating shaft 1132.

[0033] Since the first screw nut 1113 is simultaneously mounted on the rotating shaft 1132 and the first screw 1112, when the first screw 1112 rotates, the first screw nut 1113 and the first screw 1112 can be restricted from rotating synchronously, thereby restricting the first clamping plate 1114 and the second clamping plate 1115 from rotating around the axis of the first screw 1112, thereby completing the clamping action of the leek.

[0034] In order to be able to shear the clamped leeks, in this embodiment, Figure 3 and Figure 5 As shown, the shearing mechanism 112 includes a third motor 1126, a shearing knife 1127, and a pushing mechanism for pushing the third motor 1126 and the shearing knife 1127 to move and shear the leeks. Specifically, the shearing knife 1127 is fixedly mounted on the output shaft of the third motor 1126, wherein the third motor 1126 is located directly below the gap after clamping of the first clamping plate 1114 and the second clamping plate 1115.

[0035] Through the above arrangement, under normal circumstances, the first clamping plate 1114 and the second clamping plate 1115 are rectangular. When the first clamping plate 1114 and the second clamping plate 1115 clamp the leeks, they will clamp a plurality of leeks at the same time, and the plurality of leeks are arranged along the length direction of the frame 1. After the leeks are clamped, the third motor 1126 is driven, thereby driving the shearing knife 1127 to rotate at a high speed, and then the pushing mechanism is used to push the third motor 1126 and the shearing knife 1127 forward to cut the clamped leeks.

[0036] The shearing knife 1127 cuts the leeks in the process of the pushing mechanism pushing forward. In order to prevent the leeks at the clamping end from escaping from the gap between the first clamping plate 1114 and the second clamping plate 1115, in this embodiment, Figure 4 and Figure 5 As shown, a groove 11141 is provided at the tail end of the first clamping plate 1114, and a flange 11151 is provided at the tail end of the second clamping plate 1115. After the leek is clamped, the flange 11151 on the second clamping plate 1115 is inserted into the groove 11141 of the first clamping plate 1114. Specifically, the clamping gap between the first clamping plate 1114 and the second clamping plate 1115 is in a horizontal "L" shape; when the pushing mechanism pushes and shears the leek, the end of the leek abuts against the side of the flange 11151, thereby limiting the leek from escaping from the clamping mechanism 111, thereby improving the stability of the leek during the shearing process.

[0037] In order to realize the pushing of the third motor 1126 and the shearing knife 1127, in this embodiment, Figure 3As shown, the pushing mechanism includes a second motor 1121, a second screw rod 1122, a first guide rod 1123, a second screw nut 1124 and a mounting plate 1128, wherein the second screw rod 1122 and the first guide rod 1123 are parallel to each other and are arranged along the length direction of the frame 1, the output shaft of the second motor 1121 is fixedly connected to the second screw rod 1122, the second screw nut 1124 is threadedly connected to the second screw rod 1122, one end of the mounting plate 1128 is fixedly connected to the second screw nut 1124, and the other end of the mounting plate 1128 is slidably connected to the first guide rod 1123, wherein the third motor 1126 is fixedly mounted on the mounting plate 1128.

[0038] In order to realize the sliding connection between the mounting plate 1128 and the first guide rod 1123 , in the present embodiment, the pushing mechanism further includes a first slider 1125 , wherein the first slider 1125 is slidingly connected to the first guide rod 1123 , and the first slider 1125 is fixedly connected to the mounting plate 1128 .

[0039] In order to realize the turning over of the shearing component 11, the sheared leeks are transferred to the transport component 12. In this embodiment, Figure 2 and Figure 4 As shown, the flip mechanism 113 includes a fourth motor 1131 and a first positioning seat 1133 fixedly mounted on the extension arm 101 , wherein the rotating shaft 1132 is rotationally connected to the first positioning seat 1133 , and the fourth motor 1131 is power-connected to the rotating shaft 1132 .

[0040] Specifically, in this embodiment, if Figure 2 As shown, a vertically arranged longitudinal beam 102 is fixedly provided on the vehicle frame 1, wherein the fourth motor 1131 is fixedly mounted on the longitudinal beam 102, and the output shaft of the fourth motor 1131 and the rotating shaft 1132 transmit power via a synchronous belt.

[0041] Through the above arrangement, after the fourth motor 1131 is driven, the rotating shaft 1132 is driven to rotate through the synchronous belt. Since the rotating shaft 1132 is fixedly connected to the positioning plate 110 through the second positioning seat 1134, it can drive the positioning plate 110 and the shearing component 11 to flip upwards. Figure 4 As shown in the state in , at this time, the first motor 1111 drives the first screw rod 1112 to rotate, so that the first clamping plate 1114 and the second clamping plate 1115 release the clamping of the leek, thereby enabling the leek to be transferred to the transfer component 12.

[0042] In order to receive the cut leeks, in this embodiment, Figure 1As shown, the transfer component 12 includes a transfer hopper 121 for receiving the shearing component 11, a lifting mechanism 122 for lifting the transfer hopper 121, and a dumping mechanism 123 for transferring the leeks in the transfer hopper 121 to the storage box 13. Specifically, when the shearing component 11 is flipped to Figure 4 When in the middle state, the transfer hopper 121 is located at the bottom of the frame 1 and the transfer hopper 121 is in a horizontal state.

[0043] In order to realize the installation of the transfer hopper 121, in this embodiment, as Figure 6 and Figure 7 As shown, the transfer component 12 includes a lifting plate 120, wherein the lifting plate 120 is slidably connected to the frame 1 along the height direction of the frame 1, and a mounting seat 1201 is fixedly provided on the lifting plate 120, wherein the mounting seat 1201 is located on the side of the transfer hopper 121 and is rotatably connected to the side wall of the transfer hopper 121.

[0044] In order to realize the lifting and lowering of the lifting plate 120 and the transfer hopper 121, in this embodiment, as shown in FIG. Figure 6 As shown, the lifting mechanism 122 includes a fifth motor 1221, a pulley 1222, a conveyor belt 1223 and a clamping seat 1224, wherein the fifth motor 1221 is fixedly mounted on the bottom of the frame 1, the pulley 1222 is fixedly mounted on the top of the frame 1, the conveyor belt 1223 passes around the pulley 1222 and the pulley of the output shaft of the fifth motor 1221, the clamping seat 1224 is fixedly clamped on the conveyor belt 1223, and the clamping seat 1224 is fixedly connected to the lifting plate 120.

[0045] Through the above arrangement, the fifth motor 1221 is driven, which in turn can drive the conveyor belt 1223 to move, and can further drive the clamping seat 1224 to move up and down. Since the clamping seat 1224 is fixedly connected to the lifting plate 120, the lifting and lowering of the lifting plate 120 and the transfer hopper 121 can be controlled.

[0046] In order to improve the stability of the lifting plate 120, in this embodiment, Figure 1 , Figure 6 and Figure 7 As shown, it also includes a guide mechanism 124 for guiding the lifting plate 120. Specifically, the guide mechanism 124 includes a plurality of second guide rods 1241, wherein the second guide rods 1241 are vertically arranged and fixedly connected to the frame 1, and a second slider 1242 is sleeved on the second guide rods 1241, wherein the second slider 1242 is slidably connected to the second guide rods 1241, and the second slider 1242 is fixedly connected to the lifting plate 120.

[0047] It is worth pointing out here that Figure 7 As shown, a pouring port 1211 is provided on one side of the transfer hopper 121, wherein the pouring port 1211 is close to one side of the storage box 13. When the leeks in the transfer hopper 121 need to be transferred to the inside of the storage box 13, the transfer hopper 121 is raised to the top of the frame 1 by the lifting mechanism 122. At this time, the transfer hopper 121 is pushed by the dumping mechanism 123 to make the transfer hopper 121 flip around the mounting seat 1201, so that the transfer hopper 121 is in an inclined state, as shown in FIG. Figure 7 As shown, at this time, the leeks in the transfer hopper 121 slide downward along the bottom wall of the transfer hopper 121 and then pass through the pouring port 1211 into the storage box 13.

[0048] In order to tilt the transfer hopper 121, in this embodiment, Figure 7 As shown, the dumping mechanism 123 includes a sixth motor 1231 and a push guide wheel 1232, wherein the sixth motor 1231 is fixedly mounted on the lifting plate 120, the push guide wheel 1232 is fixedly connected to the output shaft of the sixth motor 1231, the push guide wheel 1232 abuts against the bottom wall of the transfer hopper 121. It is worth noting that the push guide wheel 1232 is provided with a push guide rail 1233 which is not on the same horizontal plane, wherein the push guide rail 1233 abuts against the bottom wall of the transfer hopper 121.

[0049] Through the above arrangement, the sixth motor 1231 is driven, thereby driving the push guide wheel 1232 to rotate, thereby changing the contact position between the push guide rail 1233 and the bottom wall of the transfer hopper 121, so that the inclination angle of the transfer hopper 121 can be adjusted to make the leeks slide into the storage box 13.

[0050] When the leeks are transferred, the transfer hopper 121 returns to a horizontal state through the rotation of the push guide wheel 1232, and under the action of the lifting mechanism 122, the lifting plate 120 and the transfer hopper 121 fall back to the bottom of the frame 1, so as to facilitate the reception of the next wave of cut leeks.

[0051] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
