Description

Technical Field

[0001] The utility model relates to the technical field of hawthorn jujube picking, in particular to a hawthorn jujube picking device for long-branch hawthorn jujube clusters. Background Art

[0002] Jujube is a native food that grows mostly in mountainous areas. Its leaves are elliptical to ovate-lanceolate with fine serrations on the edges; the flowers are yellow-green; the fruit is small, nearly spherical or short rectangular, reddish-brown when ripe, and sour. After the jujube is ripe, it needs to be picked using a picking device.

[0003] According to the patent publication number CN220897231U, a device for picking jujubes for long-branch jujube bushes is disclosed, which includes a handle, a side support rod welded to one end of the handle, a lower edge rod welded to the end of the side support rod facing away from the handle, a plurality of comb teeth fixedly welded to the inner side of the lower edge rod, a plastic can fixedly bonded to the side support rod and the bottom of the lower edge rod, and a cloth bag fixed to the bottom of the plastic can, the side support rod and the lower edge rod are both U-shaped, a separation groove is formed at the bottom of the plastic can, a U-shaped pad is fixedly welded to the bottom of the separation groove, an outer frame is placed on the pad, and a grille for intercepting branches in the jujube is installed on the inner side of the outer frame, a side groove is opened on one side of the separation groove toward the inside of the plastic can, and a spring and a rebound block connected to each other are provided in the side groove.

[0004] The above scheme can intercept most of the branches contained therein, so that the jujubes can finally fall into the cloth bag, and most of the branches are intercepted, realizing the automatic separation of the branches. However, the above scheme can only realize the preliminary separation of the jujubes from the branches, and is insufficient for the further processing of the jujubes after picking. In actual production, jujubes of different sizes have different uses. For example, larger jujubes may be more suitable for whole-fruit processing, while smaller jujubes may be more suitable for making products such as jujube juice. The above scheme is not convenient for automatically sorting jujubes of different sizes during or immediately after picking, which results in a large amount of manpower and time required for secondary sorting. This is not only inefficient, but also increases production costs and cannot meet the needs of efficient and precise agricultural production. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a device for picking jujubes from long-branch jujube bushes.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a device for picking jujubes for long-branch jujube clusters, comprising a frame, a handle fixedly connected to the outer surface of the frame, a group of side baffles fixedly connected to the outer surface of the frame, separation teeth fixedly connected to the outer surface of the frame, a screening assembly provided inside the frame, a collecting assembly provided inside the frame, and a limiting assembly provided on the outer side of the frame.

[0007] Furthermore, the screening component includes an inclined plate fixedly connected to the inner wall of the frame, the interior of the inclined plate is provided with sieve hole 1, the interior of the inclined plate is provided with sieve hole 2, and the interior of the inclined plate is provided with sieve hole 3.

[0009] Furthermore, the inner wall of the limiting frame is slidably connected to the sorting frame, the inner wall of the sorting frame is fixedly connected to a buffer pad, and the outer surface of the sorting frame is fixedly connected to a belt 1.

[0010] Furthermore, the limiting assembly includes an insertion rod slidably connected to the inner wall of the frame, and the insertion rod is inserted into the interior of the limiting piece, the outer surface of the insertion rod is fixedly connected to a connecting plate, and the outer surface of the connecting plate is fixedly connected to belt 2.

[0011] Furthermore, an elastic member is sleeved on the outer surface of the insertion rod, one end of the elastic member is fixedly connected to the outer surface of the connecting plate, and the other end of the elastic member is fixedly connected to the outer surface of the frame.

[0012] Compared with the existing technology, the long-branch jujube bush picking device has the following beneficial effects:

[0013] The utility model can pick the sour jujubes by arranging the separation teeth, can screen the picked sour jujubes by arranging the screening component, and can store the screened sour jujubes by arranging the collecting component. The separation teeth, the screening component and the collecting component cooperate with each other, thereby facilitating automatic sorting of sour jujubes of different sizes during the picking process or immediately after picking, with high sorting efficiency, reduced production costs, and meeting the needs of efficient and precise agricultural production.

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] This embodiment provides a jujube picking device for long-branch jujube clusters. The utility model can pick jujubes by setting separation teeth 4, can screen the picked jujubes by setting a screening component 5, and can store the screened jujubes by setting a collecting component 6. The separation teeth 4, the screening component 5 and the collecting component 6 cooperate with each other, thereby facilitating automatic sorting of jujubes of different sizes during the picking process or immediately after picking, with high sorting efficiency, reduced production costs, and meeting the needs of efficient and precise agricultural production.

[0023] See also Figures 1 to 5 A well-designed device for picking jujubes from long-branch jujube bushes has a core structure of a frame 1, which is made of high-strength aluminum alloy. This material has the advantages of light weight, high strength and corrosion resistance, ensuring the stability and durability of the device during long-term use. The frame 1 is a rectangular parallelepiped as a whole, and its size is reasonably designed, which not only ensures sufficient internal space for accommodating the screening component 5 and the collecting component 6, but also facilitates hand-held operation by the operator.

[0024] A handle 2 is firmly fixed to the outer surface of the frame 1. The handle 2 adopts an ergonomic design, and its shape fits the gripping posture of the human hand. The surface is wrapped with soft rubber material and has good anti-slip properties, so that the operator can hold the device comfortably and firmly during use, effectively reducing hand fatigue and improving the accuracy and efficiency of operation.

[0025] A group of side baffles 3 are also fixedly connected to the outer surface of the frame 1. The side baffles 3 are made of transparent polycarbonate plastic with good toughness and transparency. They are arc-shaped and extend upward from both sides of the frame 1 with moderate height. The main function of the side baffles 3 is to prevent the sour dates from falling from the sides when picking them, and to ensure that the sour dates can accurately fall into the screening component 5 inside the frame 1.

[0026] The outer surface of the frame 1 is fixedly connected with a separation tooth 4, which is made of stainless steel, has a hard and sharp texture, and is in the shape of a slender cone with a slightly curved tip in a hook shape. This design allows the separation tooth 4 to easily insert into the gap between the branch and the jujube when it contacts the jujube branch, and use the lever principle to separate the jujube from the branch without causing excessive damage to the branch, thereby ensuring the healthy growth of the jujube tree. The separation teeth 4 are evenly distributed at the front end of the frame 1, and the number and spacing are reasonably set according to the growth characteristics of the jujube bush to ensure that the jujube can be picked efficiently.

[0027] A screening assembly 5 is provided inside the frame 1 .

[0028] The screening assembly 5 includes an inclined plate 501 fixedly connected to the inner wall of the frame 1. The inclined plate 501 is made of stainless steel plate and the surface is polished to have good smoothness, which facilitates the rolling of the sour jujube on its surface. The inclined plate 501 is inclined as a whole, and the angle with the horizontal direction is between thirty and forty-five degrees. This inclination angle is conducive to the natural downward rolling of the sour jujube under the action of gravity.

[0029] Sieve hole 1 502, sieve hole 2 503 and sieve hole 3 504 are provided inside the inclined plate 501. The diameter of sieve hole 1 502 is smaller and is used to screen out smaller-sized sour dates; the diameter of sieve hole 2 503 is moderate and can screen out medium-sized sour dates; the diameter of sieve hole 3 504 is larger and is used to screen out larger sour dates. The shape of the sieve holes is circular and the edges are rounded to prevent the sour dates from being scratched during the screening process. The sieve holes are staggered. Through this design, sour dates of different sizes can be naturally rolled and screened on the inclined plate 501 to achieve automatic classification.

[0030] A collecting assembly 6 is provided inside the frame 1 .

[0031] The collecting component 6 includes a limit frame 601 slidably connected to the inner wall of the frame 1. The limit frame 601 is made of hard plastic and has certain flexibility and wear resistance. It is shaped like a rectangular frame and fits tightly with the inner wall of the frame 1 and can slide smoothly inside the frame 1.

[0032] The outer surface of the limit frame 601 is fixedly connected to a pull ring 602, which is a circular metal ring, which makes it convenient for the operator to pull the limit frame 601. The outer surface of the limit frame 601 is also fixedly connected to a limit plate 603, which is a protruding plastic plate. Its shape and position match the insertion rod 701, and is used to cooperate with the insertion rod 701 to fix the limit frame 601.

[0033] The inner wall of the limiting frame 601 is slidably connected to the sorting frame 604. The sorting frame 604 is made of food-grade plastic, which is safe and non-toxic and meets hygiene standards. The inner wall of the sorting frame 604 is fixedly connected to a buffer pad 605. The buffer pad 605 is made of sponge material, is soft and has good elasticity. When the sour jujube falls into the sorting frame 604, the buffer pad 605 can effectively absorb the impact force of the sour jujube when it falls, preventing the sour jujube from being damaged.

[0034] The outer surface of the sorting frame 604 is fixedly connected to a belt 1 606. The belt 1 606 is made of rubber and has good flexibility and friction. The function of the belt 1 606 is to facilitate the operator to remove the sorting frame 604 from the limit frame 601. At the same time, it can provide a stable lifting point during the removal process to prevent the sorting frame 604 from slipping.

[0035] A limiting assembly 7 is provided on the outer side of the frame 1 .

[0036] The limiting component 7 includes an insertion rod 701 that is slidably connected to the inner wall of the frame 1. The insertion rod 701 is a cylindrical rod made of stainless steel with a smooth surface, which is convenient for sliding on the inner wall of the frame 1 and the limiting plate 603. The insertion rod 701 is inserted into the inside of the limiting plate 603. Its length and diameter are adapted to the socket of the limiting plate 603, and it can be accurately inserted and play the role of fixing the limiting frame 601.

[0037] The outer surface of the insertion rod 701 is fixedly connected to a connecting plate 702, which is a flat plate made of plastic material. Its shape and size are convenient for the operator to apply force. The outer surface of the connecting plate 702 is fixedly connected to a belt 2 703, which is also made of rubber material, making it convenient for the operator to pull the connecting plate 702 and thereby drive the insertion rod 701 to move.

[0038] The outer surface of the insertion rod 701 is provided with an elastic member 704. The elastic member 704 is a spring with a moderate elastic coefficient, which can provide sufficient elastic force to keep the insertion rod 701 in a fixed position and facilitate the operator to pull out the insertion rod 701 by overcoming the elastic force. One end of the elastic member 704 is fixedly connected to the outer surface of the connecting plate 702, and the other end of the elastic member 704 is fixedly connected to the outer surface of the frame body 1. Through this connection method, it is ensured that the insertion rod 701 can stably limit the limit frame 601 under normal conditions. When the sorting frame 604 needs to be taken out, the operator The operator pulls the belt 2 703 upwards, which can drive the connecting plate 702 and the insertion rod 701 to overcome the elastic force of the elastic member 704 and move upwards, so that the insertion rod 701 is quickly pulled out from the limiting piece 603 and the fixed limit on the limiting frame 601 is released, thereby facilitating pulling the pull ring 602 to drive the limiting frame 601 and the sorting frame 604 to be pulled out from the inside of the frame body 1, thereby achieving the purpose of quickly taking out the sorted hawthorns. This structural design is ingenious, and the various components cooperate closely, making the entire device easy and efficient to operate, and can meet the needs of picking and automatically sorting hawthorns from long-branch hawthorn bushes.

[0039] Working principle: When the present invention is in use, the handle 2 is held to bring the device close to a long-branched jujube bush, and the separating teeth 4 are used to pick the jujubes, and the picked jujubes fall into the screening component 5 in the frame 1. Since the inclined plate 501 is provided with sieve holes 1 502, sieve holes 2 503 and sieve holes 3 504 of different sizes, the jujubes are naturally rolled and screened under the action of gravity. The smaller jujubes pass through the sieve hole 1 502 and fall into the corresponding sorting frame 604 below, the medium-sized jujubes pass through the sieve hole 2 503 and fall into the corresponding sorting frame 604 below, and the larger jujubes pass through the sieve hole 3 504 and fall into the corresponding sorting frame 604 below, thereby realizing automatic sorting of the jujubes, and the jujubes fall on the buffer pad 605, which plays a buffering and protective role for the jujubes. When it is necessary to take out the sour jujube, the belt 2 703 is pulled upward, driving the connecting plate 702 and the insertion rod 701 to move upward, and the insertion rod 701 overcomes the elasticity of the elastic member 704 and is pulled out from the limiting piece 603, releasing the fixed limit of the limiting frame 601. At this time, the pull ring 602 is pulled to drive the limiting frame 601, the sorting frame 604, etc. to be pulled out from the inside of the frame body 1. Finally, the corresponding sorting frame 604 is pulled upward by holding the belt 1 606 to quickly take out the sorted sour jujube. Through the cooperation between the separation teeth 4, the screening component 5 and the collecting component 6, it is convenient to automatically sort sour jujubes of different sizes during the picking process or immediately after picking, which has high sorting efficiency, reduces production costs, and meets the needs of efficient and precise agricultural production.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
