Description

Technical Field

[0001] The invention relates to the technical field of garlic harvesting equipment, in particular to a garlic harvesting clamping device with manually adjusted row spacing. Background Art

[0002] Garlic is affected by factors such as climate differences in different regions, and the row spacing of garlic in different regions will be different. The row spacing of existing garlic harvesting equipment cannot be adjusted. When mechanized harvesting of garlic with different row spacings is carried out, it is necessary to prepare a variety of harvesting equipment with different row spacings, resulting in low mechanized harvesting efficiency.

[0003] In addition, the existing garlic harvesting equipment has the problem that the wheel groove of the synchronous belt wheel is stuck with grass, and the garlic seedlings cannot be clamped by the harvesting clamping device when they fall to the ground.

[0004] To this end, the present application designs a garlic harvesting clamping device with manually adjusted row spacing to solve the above problems. Summary of the invention

[0005] In order to make up for the deficiencies in the prior art, the present invention provides a garlic harvesting clamping device with manually adjustable row spacing, comprising a single clamping mechanism, characterized in that: The monomer clamping mechanisms are arranged in multiple numbers side by side, and are used to clamp the garlic seedlings and lift the garlic for harvesting. The monomer clamping mechanisms are installed on the frame through the adjustment shaft. As the adjustment shaft rotates, the spacing between adjacent monomer clamping mechanisms changes equidistantly.

[0006] Furthermore, in order to better realize the present invention, the single clamping mechanism includes two synchronous belt mechanisms that are fitted side by side. The two sets of synchronous belt mechanisms clamp the garlic sprouts at the fitting part to lift the garlic out of the soil. The last synchronous belt pulley at the rear of the synchronous belt mechanism is vertically fixedly connected to a transmission shaft, and the top of the transmission shaft is transmission-connected to a hydraulic oil pump.

[0007] Furthermore, in order to better implement the present invention, a groove scraper is provided on one side of each synchronous pulley of the single clamping mechanism, and the tip of the groove scraper faces the direction in which the synchronous pulley rotates.

[0008] Furthermore, in order to better implement the present invention, a rectangular shifting strip made of a rubber strip is fixedly connected to the bottom of the synchronous pulley at the front end of the single clamping mechanism.

[0009] Furthermore, in order to better implement the present invention, the single clamping mechanism is threadedly connected below the adjusting shaft through an adjusting nut.

[0010] Furthermore, in order to better realize the present invention, two adjusting shafts are provided, which are parallel and rotatably connected to the frame, and the two adjusting shafts are connected by a chain transmission. An external hexagonal protrusion is provided at the end of one of the adjusting shafts, and the external hexagonal protrusion is driven to rotate by an external socket wrench.

[0011] Furthermore, in order to better implement the present invention, the thread rotation direction of the left half of the adjusting shaft is opposite to the thread rotation direction of the right half.

[0012] Furthermore, in order to better realize the present invention, the position where each thread on the adjusting shaft is connected to a single clamping mechanism is set as a section. If there are 8 single clamping mechanisms, the adjusting shaft is divided into 8 sections of threads. The two innermost sections of threads are the first group, and the threads on both sides of the first group are the second group. The pitches of the four groups of threads increase 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.

[0013] Furthermore, in order to better realize the present invention, a garlic sprout removal device is provided at the end of the single clamping mechanism, and the garlic sprout removal device includes two triangular rotating bodies rotatably connected to the frame, and the two rotating triangular rotating bodies clamp the garlic sprouts to the rear.

[0014] The beneficial effects of the present invention are: The present invention can adjust the spacing between adjacent single clamping mechanisms by rotating the adjusting shaft. Due to the different designed pitches and thread directions, all single clamping mechanisms can be ensured to move uniformly at the same interval. In addition, the designed toggle bar can straighten the tilted garlic sprouts to avoid missing garlic. The garlic sprout removal device can better remove the garlic sprouts in the clamping mechanism. The wheel groove scraper can clean the garlic leaves and weeds carried on the wheel at any time. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0019] Figure 1-Figure 5 This is a specific embodiment of the present invention, which is a garlic harvesting clamping device with manually adjusted row spacing. A plurality of single clamping mechanisms 1 are arranged side by side. The single clamping mechanism 1 is used to clamp the garlic seedlings and lift the garlic for harvesting. The single clamping mechanism 1 is installed on the frame 2 through the adjustment shaft 3. As the adjustment shaft 3 rotates, the spacing between adjacent single clamping mechanisms 1 changes equidistantly.

[0020] 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 at the attached part to lift the garlic out of the soil. The last synchronous belt pulley 105 at the rear of the synchronous belt mechanism is vertically fixedly connected to a transmission shaft 103, and the top of the transmission shaft 103 is transmission-connected to a hydraulic oil pump 104.

[0021] A wheel groove scraper 105 is provided on one side of each synchronous pulley 102 of the monomer clamping mechanism 1, and the tip of the wheel groove scraper 105 faces the direction from which the synchronous pulley 102 rotates. During the working process, garlic leaves, weeds, etc. carried on the wheel can be cleaned at any time.

[0022] A rectangular toggle bar 106 made of rubber strip is fixedly connected to the bottom of the most front synchronous belt wheel 102 of the monomer clamping mechanism 1. When the garlic sprouts are tilted and attached to the ground, the toggle bar 106 can straighten the garlic sprouts, and finally they are clamped and lifted by two adjacent synchronous belts.

[0023] A garlic sprout removal device 4 is provided at the end of the single clamping mechanism 1. 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.

[0024] Two adjusting shafts 3 are provided, which are parallel and rotatably connected to the frame 2. The two adjusting shafts 3 are connected by a chain transmission. An external hexagonal protrusion 301 is provided at the end of one of the adjusting shafts 3. The external hexagonal protrusion 301 is rotated by an external socket wrench to drive the adjusting shaft 3 to rotate.

[0025] The direction of the thread on the left half of the adjustment shaft 3 is opposite to that on the right half. The position where each thread on the adjustment shaft 3 is connected to a single clamping mechanism 1 is set as one section. If there are 8 single clamping mechanisms 1, the adjustment shaft 3 is divided into 8 sections of threads. The two innermost sections of threads 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. That is, Figure 5 The pitch ratio of the first thread 303, the second thread 304, the third thread 305 and the fourth thread 306 is 1:3:5:7, and the four threads have the same rotation direction.
