Description

Technical Field

[0001] The utility model relates to the technical field of leek harvesting equipment, in particular to a leek harvester. Background Art

[0002] The main growing seasons for leeks are spring and autumn. The leeks harvested in these two seasons are tender and of good quality. In summer, due to the high temperature, leeks grow fast but of relatively poor quality. They are usually used to harvest leek flowers or for root care. In winter, leeks can be harvested for the first time about 20 days after the beginning of spring.

[0003] The harvesting of leeks is mostly done by manpower, but manpower requires employees to bend over frequently, which can easily cause lumbar muscle strain. Alternatively, harvesters are used for harvesting, but the existing equipment is relatively large and heavy, with complex structures and difficult to operate. When harvesting leeks with different planting distances, the equipment is too wide to take care of both ends, and too narrow for the equipment to pass. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings in the prior art, a technical problem is to provide a leek harvester.

[0005] The technical scheme is as follows: A leek harvester comprises a base plate, a walking wheel, a guide rod, a skateboard, a cutting wheel, a mounting frame, a retracting claw and a motor, wherein walking wheels are arranged on the left and right sides of the base plate, a straight groove is opened in the middle of the base plate, a guide rod is fixedly connected to the straight groove, two skateboards are slidably connected to the guide rod, the two skateboards are rotatably connected to the cutting wheel on the sides away from each other, the two skateboards are also fixedly connected to the mounting frame on the sides away from each other, the two mounting frames are rotatably arranged with retracting claws on the ends away from the connection with the adjacent skateboards, motors a are installed on the two skateboards near the adjacent cutting wheels, the output shaft ends of motor a are fixedly connected to the adjacent cutting wheels, motors b are installed on the two mounting frames near the adjacent retracting claws, the output shaft ends of motor b are fixedly connected to the adjacent retracting claws, and an adjustment component is also included, and an adjustment component for adjusting the distance between the two skateboards is arranged on the base plate.

[0006] Optionally, the adjustment assembly includes a shell, a push rod, a bidirectional screw, a clamping rod and an elastic member. The shell is fixedly connected to the top of the bottom plate, the push rod is fixedly connected to the rear side of the top of the shell, and a bidirectional screw is rotatably connected between the left and right panels of the shell. The bidirectional screw passes through the upper parts of the two sliders and cooperates with the two sliders respectively through threads. The right end of the bidirectional screw passes through the right panel of the shell and is fixedly connected to a fixing plate. Two clamping rods are slidably connected to the fixing plate. A plurality of clamping slots are arranged at intervals on the right panel of the shell, and the clamping rods can be inserted into the clamping slots. Elastic members are connected between the two clamping rods and the fixing plate.

[0007] Optionally, a limiting plate and an extrusion plate are further included, the two slide plates are fixedly connected to the limiting plate at one side away from each other, and the two mounting frames are fixedly connected to the extrusion plate at one end away from the connection with the adjacent slide plates.

[0008] Optionally, a rubber sleeve is also included, and a rubber sleeve is arranged in the middle of the push rod.

[0009] Optionally, a bracket is also included, and the bracket is clamped on the front side of the base plate.

[0010] Optionally, a handle is further included, and the handle is fixedly connected between the right ends of the two clamping rods.

[0011] The beneficial effects of the utility model are as follows: 1. By arranging two groups of cutting wheels and gathering claws, leeks in two places can be harvested at the same time. The bidirectional screw and the like are optimally arranged. The distance between the two groups of cutting wheels and the gathering claws can be adjusted by rotating the bidirectional screw, thereby being able to adapt to the smooth harvesting of leeks at different planting distances.

[0012] 2. By setting the limiting plate and the extrusion plate, it can be prevented that the cut leeks fall into the gap between the bottom plate and the cutting wheel or between the mounting frame and the retracting claws, causing the cut leeks to be entangled on the cutting wheel or the retracting claws.

DETAILED DESCRIPTION

[0019] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0020] Embodiment: A leek harvester, such as Figure 1-Figure 5 As shown, it includes a base plate 1, a walking wheel 2, a guide rod 4, a skateboard 5, a cutting wheel 6, a mounting frame 7, a retracting claw 8 and a motor. Walking wheels 2 are arranged on the left and right sides of the base plate 1. A straight groove is opened in the middle of the base plate 1, and a guide rod 4 is fixedly connected to the straight groove. Two skateboards 5 are slidably connected to the guide rod 4. The sides of the two skateboards 5 away from each other are rotatably connected with the cutting wheel 6. The sides of the two skateboards 5 away from each other are also fixedly connected with the mounting frame 7. The ends of the two mounting frames 7 away from the connection with the adjacent skateboards 5 are rotatably provided with retracting claws 8. Motors a9 are installed on the two skateboards 5 near the adjacent cutting wheels 6, and the output shaft ends of the motor a9 are fixedly connected to the adjacent cutting wheels 6. Motors b91 are installed on the two mounting frames 7 near the adjacent retracting claws 8, and the output shaft ends of the motor b91 are fixedly connected to the adjacent retracting claws 8. An adjusting component is also included. The base plate 1 is provided with an adjusting component for adjusting the distance between the two skateboards 5.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the adjustment component includes a shell 10, a push rod 3, a bidirectional screw 11, a clamping rod 12 and an elastic member 13. The top of the bottom plate 1 is fixedly connected to the shell 10, the rear side of the top of the shell 10 is fixedly connected to the push rod 3, the left and right panels of the shell 10 are rotatably connected with the bidirectional screw 11, the bidirectional screw 11 passes through the upper parts of the two sliders, and cooperates with the two sliders respectively through threads, the right end of the bidirectional screw 11 passes through the right panel of the shell 10, and is fixedly connected to a fixing plate, two clamping rods 12 are slidably connected to the fixing plate, a plurality of clamping grooves are provided at intervals on the right panel of the shell 10, the clamping rod 12 can be inserted into the clamping grooves, and elastic members 13 are connected between the two clamping rods 12 and the fixing plate.

[0022] First, the staff transports the device to the leek planting site, places the device between two rows of leeks, starts motor a9 and motor b91, and pushes the device forward by holding the push rod 3. Motor b91 drives the retracting claw 8 to rotate, so that the retracting claw 8 pushes the leek to the cutting wheel 6 for cutting. The lower end of the cut leek is limited by the cutting wheel 6. When the retracting claw 8 continues to rotate, the leek is pushed to the rear side. When the planting distance between the two rows of leeks changes, the bidirectional screw 11 can be rotated after the clamping rod 12 is pulled out to adjust the distance between the two sliders, thereby adjusting the distance between the two cutting wheels 6 and the two retracting claws 8, so that the device can adapt to the smooth harvesting of leeks at different planting distances.

[0023] like Figure 5 As shown, it also includes a limiting plate 14 and an extrusion plate 15. The sides of the two slide plates 5 away from each other are fixedly connected to the limiting plate 14, and the ends of the two mounting frames 7 away from the connection with the adjacent slide plates 5 are fixedly connected to the extrusion plate 15.

[0024] By providing the limiting plate 14 and the extruding plate 15, when the leeks are cut off by the cutting wheel 6 and are continuously pushed backwards by the gathering claws 8, the limiting plate 14 closes the gap between the bottom plate 1 and the cutting wheel 6, and the extruding plate 15 closes the gap between the mounting frame 7 and the gathering claws 8, thereby preventing the leeks from falling into the two gaps after being cut off and failing to fall out to the rear side in time, causing the leeks to be entangled on the cutting wheel 6 or the gathering claws 8 after being cut off.

[0025] like Figure 2 As shown, a rubber sleeve 16 is also included, and a rubber sleeve 16 is arranged in the middle of the push rod 3.

[0026] The rubber sleeve 16 can make the worker more comfortable when holding the push rod 3 , and at the same time increase the friction between the worker's hand and the push rod 3 , so that the worker's hand is not likely to slide relative to the push rod 3 .

[0027] like Figure 1 As shown, a bracket 17 is also included, and the bracket 17 is clamped on the front side of the base plate 1.

[0028] By setting the bracket 17, when the device is not in use, the bracket 17 is clamped on the front side of the base plate 1, thereby cooperating with the walking wheel 2 to keep the base plate 1 in a horizontal state, so that the retracting claw 8 and the cutting wheel 6 are in a suspended state, thereby protecting the retracting claw 8 and the cutting wheel 6.

[0029] like Figure 4 As shown, a handle 18 is also included, and the handle 18 is fixedly connected between the right ends of the two clamping rods 12.

[0030] The provision of the handle 18 makes it easier for a worker to pull out the two clamping rods 12 at the same time.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
