[0002] The seedling tray is an indispensable component of a rice transplanter, and its main function is to realize the seedling raising process of rice seedlings. The seedling tray is made of polyvinyl chloride as raw material and processed by special process formula through thermoforming. It has the characteristics of light weight, easy handling, convenient storage and low use cost.

[0003] The seedling tray can be reused. In existing large-scale seedling raising bases, it is necessary to frequently retrieve and place the seedling trays. Once the seedling trays are used, they are directly placed on the ground, and the retrieval and placement mainly rely on manual labor, with very low efficiency. With the improvement of mechanical automation level, there are also cases of using mechanical equipment to place the seedling trays. For example, the Chinese patent document with the publication number CN213280636U discloses an automatic seedling tray placing device for paddy fields. When distributing the seedling trays to the fields, it is necessary to use a disk separating mechanism to dial the seedling trays onto a turning mechanism, and the turning mechanism flips the seedling trays so that the seedling trays slide down from the seedling tray placing mechanism to complete the placing work. However, this turning mechanism can only flip to one side, causing the seedling trays to slide off unidirectionally for placing, resulting in low placing efficiency. Summary of the Utility Model

[0027] To further understand the content of the present utility model, the present utility model will be described in detail in combination with the drawings and embodiments. What is described here is only the preferred embodiment of the present utility model. Those skilled in the art can think of other ways to implement the present utility model on the basis of the preferred embodiment, and other ways also fall within the scope of the present utility model.

[0028] Embodiment 1

[0029] Refer to Figures 1-2The present embodiment provides a plate placing machine, including a plate placing mechanism 5 and a plate dividing mechanism. The plate placing mechanism 5 includes two plates which are respectively arranged on both sides of the plate dividing mechanism. The actuator moves forward or reversely to transfer the plate body from the plate dividing mechanism to the plate placing mechanism 5. The plate placing mechanism 5 lowers the plate body, and two-way plate placing can be performed.

[0030] like Figure 2 As shown, the tray separation mechanism is used to transfer the seedling tray to the tray placement mechanism, including a driving mechanism 1 and a temporary storage area for the seedling tray. The driving mechanism 1 is connected to the execution component, and the driving mechanism 1 drives the execution component to move. The execution component contacts the seedling tray in the temporary storage area of ​​the seedling tray and applies a driving force. The driving mechanism 1 drives the execution component to move forward or reversely, so that the seedling tray is separated from the temporary storage area and then translated to the tray placement mechanism 5. Compared with the transfer method of flipping to the tray placement mechanism 5 in the prior art, the execution component drives the seedling tray to translate to prevent the soil, seeds, etc. in the seedling tray from spilling out. Moreover, the forward or reverse movement of the execution component can make the seedling tray separated from the temporary storage area in a forward or reverse direction, and can enter the tray placement mechanism 5 from two directions, realizing a two-way tray placement function and improving the tray placement efficiency.

[0031] Specifically, Figure 2 As shown, in this embodiment, the driving mechanism 1 includes a motor and a sprocket pair, and the motor drives the sprocket pair to rotate. The actuator includes a push rod 2, which is fixedly mounted on the chain of the sprocket pair. The push rod 2 moves along the rotation trajectory of the chain. The push rod 2 moves to the position of the seedling tray and pushes the seedling tray to translate. The sprocket pair includes a driving sprocket pair and a driven sprocket pair, which are respectively arranged on both sides of the feeding direction of the seedling tray temporary storage area, so that the seedling tray temporary storage area has enough space to temporarily store the transferred seedling tray, and can also avoid the seedling tray from interfering with the driving sprocket pair and the driven sprocket pair. The driving sprocket pair and the driven sprocket pair are connected by a transmission rod 3, wherein the motor is connected to the driving sprocket pair by chain transmission, and the transmission rod 3 transmits power to the driven sprocket pair, so that the driven sprocket pair rotates with the driving sprocket pair.

[0032] Furthermore, the driving sprocket pair includes a first sprocket 101, a second sprocket 102, and a first chain 103. The first chain 103 connects the first sprocket 101 and the second sprocket 102. The first chain 103 surrounds the circumferences of the first sprocket 101 and the second sprocket 102, and the first chain 103 is arranged across the seedling tray temporary storage area. The driven sprocket pair includes a third sprocket 104, a fourth sprocket 105, and a second chain 106. The second chain 106 connects the third sprocket 104 and the fourth sprocket 105. The second chain 106 surrounds the circumferences of the third sprocket 104 and the fourth sprocket 105, and the second chain 106 is arranged across the seedling tray temporary storage area. The transmission rod 3 connects the first sprocket 101 and the third sprocket 104, and both ends of the push rod 2 are respectively connected to the first chain 103 and the second chain 106. Therefore, when the first chain 103 and the second chain 106 move around the circumferences of each sprocket, they can drive the push rod 2 to also move around the circumferences of the sprockets. Thus, when the push rod 2 moves to a position close to the bottom of the sprocket, it contacts the seedling tray, and then can push the seedling tray to move.

[0033] It should be noted that since the rotation direction of the motor can be changed, the rotation direction of the push rod 2 along with the chain can also be changed. Therefore, the seedling tray can be pushed in two directions, realizing the function of bidirectional tray pushing, and can realize laying the seedling tray from the tray arranging mechanisms in different directions into the paddy field.

[0034] Since the chain is movable, in order to enable the transmission rod 3 to be installed on the chain without interfering with the movement of the chain, both ends of the transmission rod 3 are respectively connected to the first chain 103 and the second chain 106 through connectors 107. The connector 107 is bent to form two end faces. One of the end faces is connected to the side surface of the first chain 103 or the second chain 106. A round hole is opened on this end face, and the pin of a single link of the chain is connected in the round hole; the other end face of the connector 107 is fixedly connected to the end of the transmission rod 3.

[0035] In order to enable the seedling tray to smoothly enter the seedling tray temporary storage area, a power assist mechanism 4 is arranged on the seedling tray inlet side of the seedling tray temporary storage area. The power assist mechanism 4 assists the seedling tray to move in the seedling tray temporary storage area, which can prevent the seedling tray from being blocked at the inlet side and improve the tray separation efficiency. On the other hand, the power assist mechanism 4 can also cover the entire length direction of the temporary storage area and assist the seedling tray to move in the entire temporary storage area. When the driving direction of the power assist mechanism 4 is changed, the seedling tray can move towards the inlet end direction of the temporary storage area, enabling the seedling tray to move from the temporary storage area to the inlet end.

[0036] Specifically, as Figure 2As shown in the figure, the power assist mechanism 4 includes a number of auxiliary belts 401 and a number of pulleys 402. The auxiliary belts 401 are sleeved on the pulleys 402, and the rotation of the pulleys 402 drives the auxiliary belts 401 to support the seedling trays and move them. When the power assist mechanism 4 is arranged on the inlet side of the temporary storage area, the length of the auxiliary belt 401 is 1 / 3 to 1 / 2 of the length of the temporary storage area; when the power assist mechanism 4 covers the length direction of the temporary storage area, the length of the auxiliary belt 401 is the same as the length of the temporary storage area.

[0037] It should be noted that the seedling tray temporary storage area is mainly composed of a metal frame, and the metal frame supports the seedling trays. The metal frame can be made of a steel frame, an aluminum alloy frame, etc. Among them, in this embodiment, the forward direction refers to the forward direction of the seedling tray placing machine, and the reverse direction refers to the direction opposite to the forward direction of the seedling tray placing machine.

[0038] As Figure 1 As shown in the figure, the forward movement of the seedling tray placing machine is mainly carried out by the traveling mechanism 6. The traveling mechanism 6 is arranged on both sides of the tray dividing mechanism, and the traveling mechanism 6 is used to drive the tray dividing mechanism and the tray placing mechanism 5 to move together. When the traveling mechanism 6 moves forward, the actuator, i.e., the push rod 2, moves in the reverse direction along with the chain, so that the seedling trays are divided from the tray dividing mechanism to the tray placing mechanism 5 at the rear side. When the traveling mechanism 6 moves backward, the push rod 2 moves in the forward direction along with the chain, so that the seedling trays are divided from the tray dividing mechanism to the tray placing mechanism 5 at the front side. A travel switch is arranged on the tray placing mechanism 5. The travel switch detects the position of the seedling tray during tray placing and sends a signal to the control system. The control system controls the alignment of the positions of each seedling tray through the signal sent by the travel switch, so that the tray placing mechanism 5 keeps multiple seedling trays neat during tray placing and improves the paving regularity of the tray placing mechanism 5. The traveling mechanism 6 of this embodiment includes track wheels that travel on the track.
