[0001] This utility model relates to the technical field, specifically to a grape berry size grading device. Background Technology

[0002] Grape berry size grading is a crucial step in grape cultivation and sales. Grading separates grapes of different sizes, better meeting market demands and increasing product value. Different grape sizes may suit different consumption scenarios; for example, larger berries may be more suitable for the high-end market, while smaller berries may be used for processing or bulk sales.

[0003] Currently, grape berry size grading is usually done manually. However, manually checking each grape berry individually results in very low grading efficiency. Furthermore, manual grading involves direct contact with the grape berries, which can easily damage them and reduce their economic value. Therefore, we have proposed a grape berry size grading device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a grape berry size grading device to solve the problem mentioned in the background art that the current manual method for grading grape berry size is inefficient and easily leads to grape berry breakage.

The guide component includes a sliding rod, a tightening bolt, a sliding seat, and a guide plate. The sliding rod is fixed to the lower side of the side guard. The sliding seat is movably sleeved on the sliding rod. The position of the sliding seat on the sliding rod is fixed by the tightening bolt. The guide plate is movably installed on the sliding seat. The guide plate is located below the grading rod.

[0006] Preferably, the end of the feed plate is a concave arc shape, and its shape is adapted to the shape of the tail end of the conveyor belt.

[0007] Preferably, the grading rod is cylindrical, and multiple groups of grading rods are arranged in pairs between the feed plate and the discharge plate, with the spacing between each group of grading rods increasing sequentially.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 The present invention provides a technical solution: a grape berry size grading device, including a conveyor belt 1, the tail end of the conveyor belt 1 is provided with a grading component for grading grape berries by size, the grading component is inclined downward at the tail end of the conveyor belt 1.

[0024] The grading assembly includes a side rail 2, a feed plate 3, a discharge plate 6, and a grading rod 11. The side rail 2 is fixed on both sides of the conveyor belt 1. The feed plate 3 and the discharge plate 6 are fixed on the inner side of the side rail 2. The grading rod 11 is fixed between the feed plate 3 and the discharge plate 6.

[0025] Furthermore, the end of the feed plate 3 is a concave arc shape, which matches the shape of the tail end of the conveyor belt 1, enabling the grapes conveyed on the conveyor belt 1 to move safely onto the feed plate 3.

[0026] Furthermore, the grading rod 11 is cylindrical, which facilitates the rolling of grape berries on the grading rod 11 to ensure the normal operation of the grading work. Multiple sets of grading rods 11 are arranged in groups of two between the feed plate 3 and the discharge plate 6. The spacing between each set of grading rods 11 increases sequentially, which allows grape berries of different sizes to fall at different positions when rolling between each set of grading rods 11, thereby automatically completing the grading of grape berries.

[0027] Furthermore, the upper surface of the feed plate 3 is provided with a triangular pyramidal distributing head 4, and the upper side of the adjacent two groups of grading rods 11 is fixed with a spacer protrusion 5. The front end of the spacer protrusion 5 is connected to the distributing head 4, and the cross section of the spacer protrusion 5 is triangular. Through the cooperation of the distributing head 4 and the spacer protrusion 5, the grapes can be concentrated on the grading rods 11 without affecting the downward rolling of the grapes, thereby ensuring that the grading work is carried out normally.

[0028] The lower side of the grading assembly is provided with a guide assembly for feeding grape berries after grading. The guide assembly includes a sliding rod 7, a tightening bolt 8, a sliding seat 9, and a guide plate 10. The sliding rod 7 is fixed to the lower side of the sidewall 2. The sliding seat 9 is movably sleeved on the sliding rod 7. The position of the sliding seat 9 on the sliding rod 7 is fixed by the tightening bolt 8. The guide plate 10 is movably installed on the sliding seat 9. The guide plate 10 is located below the grading rod 11.

[0029] Furthermore, the guide plate 10 forms a displacement structure by sliding the sliding seat 9 on the sliding rod 7, which can change the position of the guide plate 10, thereby enabling the guide plate 10 to divert grapes of different sizes to achieve grading of grapes of different sizes.

[0030] Furthermore, the guide plate 10 forms a rotating structure on the sliding seat 9 through a damping shaft, which can realize the angle change of the guide plate 10, so that the grape berries of the corresponding size segment can be safely collected and guided, ensuring the stable and safe fall of the grape berries.

[0031] Furthermore, sponges are attached to both sides of the guide plate 10 to ensure the safety of the grape berries in contact with the guide plate 10 and effectively prevent the grape berries from being damaged.

[0032] Working principle: When using this grape berry size grading device, the grape berries are first laid flat on the conveyor belt 1, and the grape berries are transported to the feed plate 3 by the conveyor belt 1. Due to the inclined setting of the feed plate 3, the grape berries will automatically slide down on the feed plate 3.

[0033] Meanwhile, the feed plate 3 is equipped with a distribution head 4, which can concentrate the grapes between the grading rods 11, so that the grapes roll down between the grading rods 11. The grading rods 11 are equipped with spacer protrusions 5 to ensure that the grapes roll down between the grading rods 11 in a stable manner. As the size of the grading rods 11 increases sequentially, as the grapes roll down, at the appropriate position, the grapes will pass through the gaps between the grading rods 11 and fall down.

[0034] Before the grading work begins, the position of the guide plate 10 on the lower side of the grading rod 11 should be adjusted according to the size class of the grape berries. First, the working position of the guide plate 10 is determined according to the spacing between the grading rods 11. Two guide plates 10 are grouped together, and the grape berries falling from the corresponding grading rods 11 between the two guide plates 10 belong to the same size class.

[0035] By loosening the tightening bolt 8, the sliding seat 9 moves on the sliding rod 7, thereby adjusting the working position of the guide plate 10. Then, the guide plate 10 is rotated to make it tilted. Under the action of the damping shaft, the tilted state of the guide plate 10 can be kept stable.

[0036] The two guide plates 10 in the same group are tilted in opposite directions, which allows the falling grapes to fall stably into the receiving box below to complete the grading of the grapes. At the same time, the guide plates 10 are equipped with sponges to ensure safe contact with the grapes.

[0037] The above describes the working process of the grading device. Any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
