AI Technical Summary
The existing seedling loading and conveying equipment lacks a fitting space tailored for seedlings in the design of the seedling box, resulting in the seedlings stacking, squeezing, and collision during the loading process, increasing the risk of violent shaking and friction during the seedling damage and transmission process, affecting the growth status and planting survival rate of the seedlings. At the same time, the transfer speed adjustment flexibility is insufficient, and the transfer speed cannot be adjusted according to different planting densities, resulting in overcrowding or too large intervals of seedlings, affecting the neat arrangement and subsequent planting process of seedlings.
A three-layer seedling box is designed, including seedling plate rack, support plate, stepper motor support rack and seedling cup. The slab rack is equipped with a raised slide rail and a pulley. The support plate is a two-layer structure, fixed by screws and nuts, and the stepper motor is connected by coupling and trapezoidal screw. The fixer passes through the support plate and the cup is placed in the holes of the support plate. This structure adjusts the rotation speed of the stepper motor through the motor, controls the transmission speed, and ensures the stability of the seedlings during the transmission process through the design of the pulley and the support plate.
Through the design of a three-layer seedling box, the seedlings can be fixed independently to avoid extrusion and collision and reduce the risk of seedling damage. At the same time, by adjusting the rotation speed of the stepper motor, the transmission speed can be flexibly controlled, adapt to the needs of different planting densities, and improve the transfer efficiency and survival rate of seedlings.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of seedling loading and conveying, in particular to a three-layer seedling loading box. Background Art
[0002] In modern agricultural production, small-scale seedling planting machinery is often designed without fully considering the characteristics of seedlings, especially in the construction of seedling boxes. Many machinery seedling boxes lack tailor-made fitting space for seedlings, resulting in messy stacking of seedlings during the filling process. This unreasonable design not only causes the seedlings to squeeze and collide with each other, but may also cause damage to the roots and stems of the seedlings. During the movement and transportation of the machinery, the violent shaking and friction of the seedlings in the box will further increase the risk of damage, which will directly affect the growth status and survival rate of the seedlings.
[0003] In addition, during the seedling transmission process, the transmission speed is not flexible enough. Most existing mechanical equipment cannot quickly adjust the transmission speed according to different planting densities and different needs, which may cause overcrowding or too large spacing of seedlings. This not only affects the neatness of the seedling arrangement, but may also have a negative impact on the subsequent planting process, and further affect the growth and development of the seedlings.
[0004] For this reason, we proposed a seedling conveying device with a built-in motor to solve the above problems. Utility Model Content
[0005] The utility model aims to provide a three-layer seedling box to solve the problems in the above-mentioned background technology that seedlings in the seedling box are easily damaged and the seedling delivery rate cannot be flexibly adjusted in the planting agricultural machine.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A three-layer seedling box includes a seedling tray frame, a support plate, a stepper motor support frame, and a seedling cup. The feature is that raised slide rails are arranged on the left and right sides of the inside of the seedling tray frame, and a pulley is placed on the raised slide rails and can fit the raised slide rails for horizontal reciprocating motion.
[0008] The support plate has two layers separated by a certain height. The pulley fixer is a component with a U-shaped cross section. The two layers of support plates are fixed on the inner upper and lower surfaces by screws and nuts, and the pulley is fixed on the outer side surface.
[0009] The stepper motor is placed inside the stepper motor support frame, and the clamping coupling connects the output shaft of the stepper motor and the trapezoidal lead screw, and the trapezoidal lead screw passes through the fixture between the two layers of support plates.
[0010] The seedling cup is placed in a hole reserved on the support plate, and the diameter of the seedling cup is slightly smaller than the diameter of the hole.
[0011] As a preferred embodiment of the utility model, the baffle (2) is fixed to and completely covers the bottom of the seedling tray rack (1), and the support plate (3) is a completely identical two-layer plate, with a 4×6 array of holes with a diameter of 12 cm reserved, and a U-shaped depression on the edge close to the motor end.
[0012] As a preferred embodiment of the utility model, the seedling tray frame is assembled from aluminum profiles into a rectangular outer contour, the raised slide rail is fixed to the bottom end of the seedling tray frame by bolts and nuts, and the pulley fits into the groove of the raised slide rail and can slide.
[0013] As a preferred embodiment of the utility model, the front and rear ends of the fixture are embedded with thread sleeves matching the size of the trapezoidal lead screw, the trapezoidal lead screw passes through the fixture, and the fixture is fixed on the central axis between the two support plates by bolts and nuts.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] The structure of one baffle plate and two support plates can independently fix the seedlings in the seedling box, which can avoid squeezing and collision between seedlings and reduce the survival rate of planting. In addition, the combination of transmission parts such as stepper motor, coupling, trapezoidal screw and fixture can transport the seedlings out of the seedling box row by row. By adjusting the speed of the stepper motor, the speed of seedling transportation can be controlled to meet the planting needs of different seedlings. BRIEF DESCRIPTION OF THE DRAWINGS

[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] Example: See Figures 1 to 5 The embodiment of the utility model provides a technical solution, a three-layer seedling box, including a seedling tray frame 1, a baffle 2, a support plate 3, a stepper motor support frame 7, and a seedling cup 8. The left and right sides of the seedling tray frame 1 are provided with raised slide rails 1-1, which are assembled from aluminum profiles, and the pulley 5 is placed on the raised slide rails 1-1; the support plate 3 has two layers, which are separated by a certain height, and the pulley fixture 4 fixes the support plate 3 and the pulley 5 respectively by bolts and nuts; the stepper motor is placed inside the stepper motor support frame 7, and the coupling 6 connects the output shaft of the stepper motor and the trapezoidal screw 10, and the trapezoidal screw passes through the fixture 9 between the two layers of the support plates 3; the seedling cup 8 is placed in the hole reserved in the support plate 3.
[0024] As an implementation method, the baffle 2 is fixed to and completely covers the bottom of the seedling tray rack 1, and the support plate 3 is a completely identical two-layer plate with a 4×6 array of holes reserved. There is a U-shaped depression on the edge near the motor end to reserve space for the motor.
[0025] As an implementation mode, the seedling tray frame 1 is assembled from aluminum profiles into a rectangular outer contour, the raised slide rail 1-1 is fixed to the bottom end of the seedling tray frame 1 by bolts and nuts, and the pulley 5 fits in the groove of the raised slide rail (1-1) and can slide.
[0026] As an implementation mode, the two ends of the fixture 9 are embedded with thread sleeves matching the size of the trapezoidal lead screw 10, the trapezoidal lead screw 10 passes through the fixture 9, and the fixture is fixed on the central axis between the two support plates 3 by bolts and nuts.
[0027] Working principle: When the three-layer seedling box is in use, the seedling cup 8 containing seedlings is first placed in the hole reserved in the support plate 3. The initial state is that the support plate 3 is not extended. If it is not the initial state, the motor should be reversed to retract the support plate 3 into the space of the seedling tray frame 1. According to the frequency of seedling transmission required, the forward rotation rate of the motor is adjusted, and the forward rotation of the motor is transmitted to the trapezoidal screw 10 through the coupling 6. The rotation of the trapezoidal screw 10 causes the support plate 3 to extend outward through the connected fixer 9. The pulley 5 plays the role of auxiliary movement. As the support plate 3 extends, the seedlings in the seedling cup 8 fall, completing the transmission of the seedlings.
