Abstract
Description
A garlic harvesting clamp device with manually adjustable row spacing Technical Field
[0001] This invention relates to the field of garlic harvesting equipment technology, and in particular to a garlic harvesting clamping device with manually adjustable row spacing. Background Technology
[0002] Garlic seed spacing varies depending on factors such as climate differences in different regions. The row spacing of garlic can vary in different areas. Existing garlic harvesting equipment does not have adjustable row spacing. When harvesting garlic with different row spacings by machinery, it is necessary to prepare a variety of harvesting equipment with different row spacings, resulting in low efficiency of mechanized harvesting.
[0003] In addition, existing garlic harvesting equipment has the problem of grass getting stuck in the grooves of the synchronous belt pulley, and garlic seedlings not being held in place by the harvesting clamping device when they are leaning to the ground.
[0004] To address this issue, this application presents a manually adjustable garlic harvesting clamping device. Summary of the Invention
[0005] To overcome the shortcomings of the prior art, this invention provides a manually adjustable garlic harvesting clamping device, comprising a single clamping mechanism, characterized in that:
[0006] Multiple individual clamping mechanisms are arranged side by side. The individual clamping mechanisms are used to clamp the garlic sprouts and lift the garlic for harvesting. The individual clamping mechanisms are installed on the frame by adjusting the rotating shaft. As the adjusting shaft rotates, the distance between adjacent individual clamping mechanisms changes equidistantly.
[0007] Furthermore, in order to better realize the present invention, the single clamping mechanism includes two synchronous belt mechanisms that are attached side by side. The two sets of synchronous belts of the synchronous belt mechanism clamp the garlic sprouts and lift the garlic out of the soil. A drive shaft is vertically fixedly connected to the last synchronous belt pulley behind the synchronous belt mechanism, and a hydraulic oil pump is connected to the top of the drive shaft.
[0008] Furthermore, in order to better realize the present invention, each synchronous pulley of the single clamping mechanism is provided with a groove scraper on one side, and the tip of the groove scraper faces the direction from which the synchronous pulley rotates.
[0009] Furthermore, in order to better realize the present invention, a rectangular actuating strip made of rubber strip is fixedly connected to the bottom of the timing pulley at the foremost end of the single clamping mechanism.
[0010] Furthermore, in order to better realize the present invention, the single clamping mechanism is threadedly connected to the lower part of the adjusting shaft via an adjusting nut.
[0011] Furthermore, in order to better realize the present invention, the adjustment shaft is provided in two parallel and rotatably connected to the frame. The two adjustment shafts are connected by chain drive. One of the adjustment shafts has an external hexagonal protrusion at its end. The external hexagonal protrusion drives the adjustment shaft to rotate by rotating an external socket wrench.
[0012] Furthermore, in order to better realize the present invention, the thread direction of the left half of the adjusting shaft is opposite to that of the right half.
[0013] Furthermore, in order to better realize the present invention, each threaded connection of a single clamping mechanism on the adjusting shaft is set as a segment. If there are 8 single clamping mechanisms, the adjusting shaft is divided into 8 thread segments. The two innermost thread segments are the first group, and the threads on both sides of the first group are the second group. The pitch of the four groups of threads increases from the inside to the outside, and the pitch ratio of the four groups of threads is 1:3:5:7 from the inside to the outside.
[0014] Furthermore, in order to better realize the present invention, the end of the single clamping mechanism is provided with a garlic sprout removal device, which includes two triangular rotating bodies rotatably connected to the frame. The two rotating triangular rotating bodies clamp the garlic sprouts to the rear.
[0015] The beneficial effects of this invention are:
[0016] This invention allows for adjustment of the spacing between adjacent individual clamping mechanisms by rotating the adjusting shaft. Due to the different designed pitch and thread direction, it ensures that all individual clamping mechanisms move uniformly by the same interval. Additionally, the designed actuating bar can straighten leaning garlic sprouts, preventing garlic from being missed. The garlic sprout removal device can better remove garlic sprouts from the clamping mechanisms, and the wheel groove scraper can clean garlic leaves and weeds carried on the wheels at any time.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0025] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0026] Figures 1-5 illustrate a specific embodiment of the present invention, which is a garlic harvesting clamping device with manually adjustable row spacing. Multiple individual clamping mechanisms 1 are arranged side by side. The individual clamping mechanisms 1 are used to clamp garlic sprouts and lift garlic for harvesting. The individual clamping mechanisms 1 are mounted on the frame 2 by adjusting the rotating shaft 3. As the adjusting rotating shaft 3 rotates, the spacing between adjacent individual clamping mechanisms 1 changes equidistantly.
[0027] The single clamping mechanism 1 includes two synchronous belt mechanisms that are attached side by side. The two sets of synchronous belts 101 of the synchronous belt mechanism clamp the garlic sprouts and lift the garlic out of the soil. The last synchronous belt pulley 105 behind the synchronous belt mechanism is vertically fixedly connected to a drive shaft 103. The top of the drive shaft 103 is connected to a hydraulic oil pump 104.
[0028] Each synchronous pulley 102 of the single clamping mechanism 1 has a groove scraper 105 on one side, with the tip of the groove scraper 105 facing the direction from which the synchronous pulley 102 rotates. During operation, garlic leaves, weeds, and other debris carried on the pulley can be cleaned at any time.
[0029] A rectangular actuating strip 106 made of rubber is fixedly connected to the bottom of the timing pulley 102 at the foremost end of the single clamping mechanism 1. When it encounters a garlic sprout that is leaning to the ground, the actuating strip 106 can straighten the garlic sprout, which is then clamped and lifted by two adjacent timing belts.
[0030] The end of the single clamping mechanism 1 is provided with a garlic sprout removal device 4. The garlic sprout removal device 4 includes two triangular rotating bodies rotatably connected to the frame 2. The two rotating triangular rotating bodies clamp the garlic sprouts to the rear.
[0031] Two adjusting shafts 3 are provided, which are rotatably connected to the frame 2 in parallel. The two adjusting shafts 3 are connected by chain drive. One of the adjusting shafts 3 has an external hexagonal protrusion 301 at its end. The external hexagonal protrusion 301 drives the adjusting shaft 3 to rotate by rotating an external socket wrench.
[0032] The thread direction on the left half of the adjusting shaft 3 is opposite to that on the right half. Each thread on the adjusting shaft 3 is connected to a single clamping mechanism 1, and if there are 8 single clamping mechanisms 1, then the adjusting shaft 3 is divided into 8 thread segments. The two innermost thread segments form the first group, and the threads on either side of the first group form the second group. The pitch of the four thread groups increases sequentially from the inside to the outside, and the pitch ratio of the four thread groups from the inside to the outside is 1:3:5:7. That is, the pitch ratio of the first thread 303, the second thread 304, the third thread 305, and the fourth thread 306 in Figure 5 is 1:3:5:7, and all four have the same thread direction.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
