Description

Technical Field

[0001] The utility model relates to the technical field of garlic harvesters, in particular to a two-stage garlic clamping device for a garlic harvester. Background Art

[0002] There are some harvesting machines in the prior art, which transport the whole garlic plant into the harvester through a scooping device at the front. The existing harvester transports the garlic plant backward through a garlic clamping device, cuts off the upper garlic seedlings through a shearing device at the rear, and then collects the garlic heads. However, the garlic clamping devices of the existing garlic harvesters use conveyor belts on both sides to transport backward. Since the length of the upper garlic seedlings entering the garlic clamping device during harvesting is the height reserved when the harvester enters the soil, the remaining garlic seedlings on the upper part of the garlic head are too long during subsequent cutting. If the harvester lowers the height when entering the soil, the depth of the shovel will be too deep, which reduces the harvesting efficiency and causes the stem cutting effect to be very unsatisfactory. It is necessary to manually re-sort and perform secondary processing. In severe cases, the garlic may even be cut, resulting in bad fruits, which affects the garlic yield. Utility Model Content

[0003] The utility model aims to overcome the defect that the garlic sprouts left on the garlic heads are too long when the garlic harvester cuts the garlic sprouts in the prior art, and provides a two-stage garlic clamping device for the garlic harvester.

[0004] The utility model is realized through the following technical scheme: a two-stage garlic clamping device for a garlic harvester, comprising a mounting frame arranged at a feeding end of the harvester, a first garlic clamping device being arranged on the mounting frame, the first garlic clamping device comprising two first clamping conveyor belts being arranged oppositely along the length direction of the mounting frame, a second clamping conveyor belt being arranged oppositely below the end of the first clamping conveyor belt, and a cutting device being arranged at the end of the second clamping conveyor belt.

[0005] Furthermore, the upward inclination angle of the second clamping conveyor belt is smaller than that of the first clamping conveyor belt.

[0006] Furthermore, a plurality of the first clamping conveyor belts and a plurality of the second clamping conveyor belts are correspondingly provided.

[0007] Furthermore, the cutting device comprises a driving motor arranged on a mounting frame, an output end of the driving motor is connected to a universal shaft via a chain, and a circular blade is arranged at the bottom of the universal shaft.

[0008] Furthermore, the central axis of the circular blade is arranged at the end of the second clamping conveyor belt, and the edges of the circular blade are overlapped with each other.

[0009] Furthermore, a plurality of tensioning wheels are provided on the conveying paths of the first clamping conveyor belt and the second clamping conveyor belt.

[0010] Furthermore, the tensioning wheel is rotatably arranged on the mounting frame via a right-angle bracket, and an adjusting bolt is arranged at one point of the right-angle bracket.

[0011] The beneficial effects of the utility model are as follows: a plurality of first clamping conveyor belts and second clamping conveyor belts are correspondingly arranged, a second clamping conveyor belt is relatively arranged below the end of the first clamping conveyor belt, the upward inclination angle of the second clamping conveyor belt is smaller than that of the first clamping conveyor belt, the garlic head is below the first clamping conveyor belt, and the length of the garlic sprouts below the first clamping conveyor belt is longer during the upward conveying process. After the garlic sprouts reach the second clamping conveyor belt, they continue to move backward through the second clamping conveyor belt. Since the second clamping conveyor belt is below the first clamping conveyor belt, the distance between the second clamping conveyor belt and the garlic head after clamping the top of the garlic head is greatly reduced compared with the first clamping conveyor belt, thereby ensuring that the garlic sprouts on the cut garlic head have a shorter length, thereby improving product quality.

Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in 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.

[0019] Example 1

[0020] like Figure 1-4 As shown: a two-stage garlic clamping device for a garlic harvester, comprising a mounting frame arranged at a feeding end of the harvester, the feeding end is mounted on a tractor through the mounting frame, a first garlic clamp is arranged on the mounting frame, the first garlic clamp comprises two first clamping conveyor belts 1 arranged oppositely along the length direction of the mounting frame, a digging knife installed at the front of the feeding end digs the garlic out of the soil, and the first clamping conveyor belts 1 are distributed one by one according to the planting direction of the garlic plants, the scooped garlic plants are transported upward along the first clamping conveyor belts 1, a second clamping conveyor belt 2 is arranged oppositely below the end of the first clamping conveyor belt 1, and the upward inclination angle of the second clamping conveyor belt 2 is smaller than that of the first clamping conveyor belt 1, A plurality of first clamping conveyor belts 1 and second clamping conveyor belts 2 are correspondingly provided. When in use, the scooped garlic plants are driven by the two first clamping conveyor belts to move obliquely upward, and the garlic heads are below the first clamping conveyor belt. During the upward conveying process, the length of the garlic sprouts below the first clamping conveyor belt 1 is longer. After the garlic sprouts reach the second clamping conveyor belt 2, they continue to move backward through the second clamping conveyor belt 2. Since the second clamping conveyor belt 2 is below the first clamping conveyor belt 1, after clamping the top of the garlic heads, the distance between the second clamping conveyor belt 2 and the garlic heads is greatly reduced compared with the first clamping conveyor belt 1, thereby ensuring that the garlic sprouts on the cut garlic heads have a shorter length, thereby improving product quality.

[0021] A cutting device is provided at the end of the second clamping conveyor belt 2, and the cutting device includes a driving motor 3 arranged on a mounting frame, and the output end of the driving motor 3 is connected to a universal shaft through a chain 301, and a circular blade 302 is provided at the bottom of the universal shaft, and the central axis of the circular blade 302 is provided at the end of the second clamping conveyor belt 2, and the edges of the circular blade 302 are stacked on each other. The circular blade 302 is connected by the universal shaft to adjust the installation angle of the circular blade 302, which is suitable for a smaller installation space on a harvester. The transmission is transmitted by the chain 301 to prevent the universal shaft from slipping, and can also assist the second clamping conveyor belt 2 to transport the cut garlic sprouts backwards, thereby improving the use effect.

[0022] A plurality of tensioning wheels 101 are arranged on the conveying paths of the first clamping conveyor belt 1 and the second clamping conveyor belt 2. The tensioning wheel 101 is rotatably arranged on the mounting frame through a right-angle bracket 102. An adjusting bolt 103 is arranged at one point of the right-angle bracket 102. The first clamping conveyor belt 1 and the second clamping conveyor belt 2 use belts, and the tensioning wheel 101 abuts against the belts. When the clamping force between the belts needs to be adjusted, the adjusting bolt 103 rotates forward to control the right-angle bracket 102 to control the tensioning wheel 101 to move the belts outward, so that the gap between the two relative belts becomes smaller. The adjustment is simple, and the operation is convenient and easy to operate.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
