Description

Technical Field

[0001] The utility model relates to the technical field of Chinese cabbage harvesting, in particular to a stratified mechanism for arranging and storing Chinese cabbage harvesters. Background Art

[0002] Chinese cabbage is a common vegetable in our daily life. It can be grown outdoors or in greenhouses. It matures in 25 to 45 days. At present, when Chinese cabbage harvesters usually arrange Chinese cabbage in planting baskets, in order to reduce the storage space, the staff usually stacks the planting baskets containing Chinese cabbage and stores them together. This will not only increase the probability of squeezing the Chinese cabbage, but also hinder the normal air circulation inside and outside the planting baskets below, affecting the freshness of the Chinese cabbage.

[0003] Therefore, a layered mechanism for arranging and storing Chinese cabbage harvesters is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a layered mechanism for arranging and storing Chinese cabbage harvesters in order to solve the above problems, thereby improving the problem that the Chinese cabbage arranged and stored in a stacked manner is easily squeezed and damaged, and the air in the planting basket is difficult to circulate normally, affecting the freshness of the Chinese cabbage.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a stratified mechanism for arranging and storing Chinese cabbage harvesters, comprising: a rectangular frame, a stratified device and a reduction device, wherein the stratified device and the reduction device are both installed on the surface of the rectangular frame, and one end of the stratified device and the reduction device penetrates into the interior of the rectangular frame.

[0006] Preferably, a mounting cavity is provided on the surface of the rectangular frame, the stratification device includes a mounting plate and evenly distributed connecting rods, the surface of the mounting plate is hinged with evenly distributed stratification hooks, the tip of the lowest stratification hook passes through the outside of the mounting cavity, the surface of the lowest stratification hook is fixedly connected with a torsion spring fixedly connected to the mounting plate, the surface of the stratification hook is provided with a first slide groove and a second slide groove, the first slide groove is arranged above the second slide groove, the two ends of the connecting rod are respectively slidably hinged with the first slide groove on one of the stratification hooks and the second slide groove on another adjacent stratification hook, when the planting net basket is pressed on the protruding stratification hook surface, the upper stratification hook is also synchronously stretched and protruded, and when the next planting net basket moves downward, the planting net basket must press the protruding stratification hook. The layer hook can not only limit the planting basket to a specified height, but also stretch and protrude the adjacent layer hook above, which can effectively separate the two planting baskets, avoid the two planting baskets from stacking and squeezing each other, and reduce the probability of the cabbage being crushed. At the same time, it also limits the spacing between the planting baskets, so that the air inside and outside the planting baskets can circulate normally to ensure the freshness of the cabbage; the torsion spring design is adopted. When the planting basket rises and separates from the layer hook, the layer hook loses pressure at this time, and the torsion spring can quickly reset the layer hook connected to it. The layer hook resets the adjacent layer hook above through the connecting rod until all the layer hooks are reset, making it convenient for the next round of layered storage operations, and there is no need for manual reset by the staff, which also reduces the workload of the staff.

[0007] Preferably, the cross-sectional shapes of the first slide groove and the second slide groove are both arc-shaped, and the length ratio of the first slide groove to the second slide groove is one to two, which can ensure that the connecting rod can only be moved after the layered hook rotates a certain angle, thereby ensuring that the planting net frame can be smoothly moved down to the designated position.

[0008] Preferably, a square cavity is formed on the surface of the rectangular frame facing the installation cavity, and the deceleration device includes a connecting shaft rotatably connected to the inside of the rectangular frame, and the surface of the connecting shaft is fixedly connected with spring pieces evenly distributed and respectively arranged on the inner sides of the square cavity. In the process of the planting net basket falling along the rectangular frame, the planting net basket inevitably contacts with the protruding spring pieces, and the planting net basket moves downward to squeeze the spring pieces, which increases the friction force during the falling process of the planting net basket, so as to alleviate the impact force during the falling process of the planting net basket, and further reduces the probability of damage to the Chinese cabbage.

[0009] Preferably, the vertical cross-section of the spring piece is in the shape of an arc, and the center point of the cross-section of the spring piece is always arranged inside the rectangular frame, which can prevent the spring piece from being stuck together with the planting basket, so as to ensure that the planting basket can move down normally.

[0010] Preferably, the deceleration device also includes a servo motor fixedly connected to the top of the rectangular frame, the output shaft of the servo motor is fixedly connected to the driving bevel gear, the surface of the driving bevel gear is meshingly connected to the driven bevel gear, and the top of the connecting shaft passes through the rectangular frame and is fixedly connected to the driven bevel gear, which can retract all the springs into the interior of the square cavity to reduce the resistance during the rising process of the planting basket.

[0011] Preferably, the vertical cross-section of the connecting shaft is stepped, and the spring piece is misaligned with the connection between the driven bevel gear and the connecting shaft, which can increase the amplitude of the rotational displacement of the spring piece and further ensure that the spring piece can completely return to the inside of the square cavity.

[0012] Preferably, the number of the installation cavity, the layering device and the deceleration device are two, and the two layering devices are installed diagonally on the surface of the rectangular frame, and the two deceleration devices are installed diagonally on the surface of the rectangular frame. This can keep the layering and deceleration operations balanced and reduce the probability of the planting basket tilting during the downward movement.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the planting net basket is pressed on the surface of the protruding layering hook, the upper layering hook is also stretched and protruded synchronously. When the next planting net basket moves down, the planting net basket must press the protruding layering hook. The layering hook can not only limit the planting net basket to a specified height, but also stretch and protrude the adjacent layering hook above. This can effectively separate the two planting net baskets, avoid the two planting net baskets from stacking and squeezing each other, and reduce the probability of the cabbage being crushed. At the same time, this also limits the spacing between the planting net baskets, so that the air inside and outside the planting net baskets can circulate normally to ensure the freshness of the cabbage.

[0015] 2. The torsion spring design is adopted. When the planting net basket rises and separates from the stratification hook, the stratification hook loses pressure at this time, and the torsion spring can quickly reset the stratification hook connected to it. The stratification hook resets the adjacent stratification hook above through the connecting rod until all the stratification hooks are reset, making it convenient for the next round of stratification storage operations, and there is no need for manual reset by the staff, which also reduces the workload of the staff;

[0016] 3. In the process of the planting net basket falling along the rectangular frame, the planting net basket will inevitably come into contact with the protruding spring pieces. The planting net basket moves downward to squeeze the spring pieces, which will increase the friction during the falling process of the planting net basket to alleviate the impact force during the falling process of the planting net basket, and further reduce the probability of damage to the cabbage.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, 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.

[0023] When implementing: Figure 1-4 As shown, a stratified mechanism for arranging and storing Chinese cabbage harvesters comprises: a rectangular frame 1, a stratified device 2 and a reduction device 3, the stratified device 2 and the reduction device 3 are both mounted on the surface of the rectangular frame 1, and one end of the stratified device 2 and the reduction device 3 penetrates into the interior of the rectangular frame 1; the number of mounting cavities 11, stratified devices 2 and reduction devices 3 are all two, two stratified devices 2 are diagonally mounted on the surface of the rectangular frame 1, and two reduction devices 3 are diagonally mounted on the surface of the rectangular frame 1.

[0024] like Figure 2 and Figure 3 As shown, a mounting cavity 11 is provided on the surface of the rectangular frame 1, and the layering device 2 includes a mounting plate 21 and evenly distributed connecting rods 25. Evenly distributed layering hooks 22 are hinged on the surface of the mounting plate 21. The tip of the lowest layering hook 22 penetrates the outside of the mounting cavity 11. A torsion spring 26 fixedly connected to the mounting plate 21 is fixedly connected to the surface of the lowest layering hook 22. A first slide groove 23 and a second slide groove 24 are provided on the surface of the layering hook 22. The first slide groove 23 is arranged above the second slide groove 24. The two ends of the connecting rod 25 are respectively slidably hinged with the first slide groove 23 on one of the layering hooks 22 and the second slide groove 24 on another adjacent layering hook 22; the cross-sectional shapes of the first slide groove 23 and the second slide groove 24 are both arc-shaped, and the length ratio of the first slide groove 23 to the second slide groove 24 is one to two;

[0025] When the planting net basket presses the lowest stratification hook 22, the planting net basket drives the stratification hook 22 to rotate downward, and the stratification hook 22 drives the first slide slot 23 and the second slide slot 24 to rotate at the same time. When the connecting rod 25 connected to the first slide slot 23 slides to the limit of the first slide slot 23, the stratification hook 22 drives the connecting rod 25 to move downward through the first slide slot 23, and the other end of the connecting rod 25 slides along the second slide slot 24. When the other end of the connecting rod 25 also slides to the limit of the second slide slot 24, the connecting rod 25 drives the adjacent upper stratification hook 22 to rotate through the second slide slot 24, so that the tip of the stratification hook 22 passes through the installation cavity 11, which can make the next planting net basket contact with the protruding stratification hook 22 during the downward movement and make The stratification hooks 22 limit the planting baskets at the corresponding height, and this action is repeated until the limit is reached and all the stratification hooks 22 are filled. This can effectively separate the two planting baskets, avoid the two planting baskets from stacking and squeezing each other, and reduce the probability of the cabbage being crushed. At the same time, this also limits the spacing between the planting baskets, so that the air inside and outside the planting baskets can circulate normally to ensure the freshness of the cabbage. When the planting basket rises and separates from the stratification hooks 22, the stratification hooks 22 lose pressure at this time, and the torsion springs 26 can quickly reset the stratification hooks 22 connected to it. The stratification hooks 22 reset the adjacent stratification hooks 22 above through the connecting rods 25 until all the stratification hooks 22 are reset, making it convenient for the next round of stratified storage operations.

[0026] like Figure 4 As shown, a square cavity 12 is provided on the surface of the rectangular frame 1 facing the installation cavity 11, and the reduction gear 3 includes a connecting shaft 31 rotatably connected to the inside of the rectangular frame 1, and the surface of the connecting shaft 31 is fixedly connected with spring pieces 32 evenly distributed and respectively arranged on the inner side of the square cavity 12; the vertical cross-sectional shape of the spring piece 32 is an arc shape, and the center point of the cross-sectional circle of the spring piece 32 is always arranged inside the rectangular frame 1; the reduction gear 3 also includes a servo motor 33 fixedly connected to the top of the rectangular frame 1, and the output shaft of the servo motor 33 is fixedly connected to the driving bevel gear 34, and the surface of the driving bevel gear 34 is meshingly connected to the driven bevel gear 35, and the top of the connecting shaft 31 passes through the rectangular frame 1 and is fixedly connected to the driven bevel gear 35; the vertical cross-sectional shape of the connecting shaft 31 is stepped, and the spring piece 32 is misaligned with the connection between the driven bevel gear 35 and the connecting shaft 31;

[0027] In the process of the planting net basket falling along the rectangular frame 1, the planting net basket inevitably contacts with the protruding spring pieces 32, and the planting net basket moves downward to squeeze the spring pieces 32, which increases the friction during the falling process of the planting net basket to alleviate the impact force during the falling process of the planting net basket, and further reduces the probability of damage to the cabbage. In addition, the staff can manually control the servo motor 33 to rotate in the corresponding direction, and the servo motor 33 drives the active bevel gear 34 to rotate, and the active bevel gear 34 drives the driven bevel gear 35 to rotate in opposite directions, and the driven bevel gear 35 drives the connecting shaft 31 to rotate, and the connecting shaft 31 drives all the spring pieces 32 to rotate, and all the spring pieces 32 are retracted into the inside of the square cavity 12 to reduce the resistance during the rising process of the planting net basket.

[0028] It should be noted that the servo motor 33, the active bevel gear 34 and the driven bevel gear 35 in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor 33 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
