DETAILED DESCRIPTION
[0020] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations.
[0021] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art without creative labor based on the embodiments in the present application are within the scope of protection of the present application.
[0022] As shown in Figures 1 to 4 An adjustable rice seedling tray conveyor includes a conveying table 101, a side plate 102 and a base 103 are arranged on the conveying table 101, a front limiting shaft 112 and a rear limiting rod 118 are slidingly arranged on the side plate 102, a front connecting shaft 111 is fixedly arranged on the front limiting shaft 112, a baffle 109 is rotatably arranged on the front connecting shaft 111, the baffle 109 is slidingly arranged on the side plate 102, a rear connecting shaft 114 is fixedly arranged on the rear limiting rod 118, a rear limiting shaft 115 is slidingly arranged on the rear connecting shaft 114, and a contact plate 117 is fixedly arranged on the rear limiting shaft 115.
[0023] Specifically, after the seedling tray is placed on the conveying table 101, the seedling tray is moved by the conveying table 101, and the placed seedling tray will present various states due to human factors, that is, as shown in Figure 2 The seedling trays are arranged irregularly, thereby affecting the subsequent seedling tray filling process and the like, so it is necessary to arrange the seedling trays regularly and maintain a certain interval distance to control the conveying of the seedling trays during conveying.
[0024] The seedling tray is adjusted by controlling the transverse movement of the baffle 109 and the contact plate 117, when the baffle 109 slides into the conveying table 101 and the contact plate 117 slides out of the conveying table 101, that is, as shown in Figure 2 At this time, the baffle 109 will block the seedling tray conveyed on the conveying table 101, so that the subsequent seedling tray will be close to and contact the front seedling tray, so that the rear seedling tray will change from being inclined to being parallel to the transverse plane, that is, the contact surface of the latter is parallel to that of the former, as shown in Figure 2The first two seedling trays are shown in their current state. Then, the baffle 109 is controlled to slide out of the conveyor table 101, and the contact plate 117 is controlled to slide into the conveyor table 101. During this process, the baffle 109 gradually detaches from the front seedling tray, while the contact plate 117 gradually approaches the rear seedling tray. Because the rear seedling tray is misaligned with the front one, one side of the contact plate 117 will push the seedling tray to slide on the conveyor table 101 and the front seedling tray until both contact plates 117 contact the rear seedling tray, thus moving the rear seedling tray to the middle position of the conveyor table 101. Then, the baffle 109 continues to move, detaching from the front seedling tray, while the two contact plates 117 slide into the conveyor table 101. 17. The tray continuously adheres to the rear seedling tray to fix it in place, so that the front seedling tray is output under the action of the conveyor 101. After the front seedling tray has completely passed the baffle 109, the baffle 109 is controlled to slide into the conveyor 101 to block the rear seedling tray. Then, by setting an interval time, the movement of the baffle 109 and the contact plate 117 is stopped within this time. After the distance between the output seedling tray and the seedling tray blocked by the baffle 109 reaches the preset interval distance, the above process is repeated, that is, the rear seedling tray is adjusted and fixed, and the seedling tray blocked by the baffle 109 is output, thereby realizing the adjustment of the direction, position and front-to-back interval of the seedling tray.
[0025] like Figure 3 As shown, an electric cylinder 104 is fixedly installed on the base 103, and a push rod 105 is fixedly installed at the output end of the electric cylinder 104. Two sliding grooves are provided on the push rod 105, and a swing arm 106 is slidably installed on each sliding groove. A rotating shaft 107 is fixedly installed on the swing arm 106, and the rotating shaft 107 is rotatably installed on the bracket of the side plate 102.
[0026] A drive rod 108 is fixedly mounted on the rotating shaft 107. The drive rod 108 has two sliding grooves, which are slidably connected to the rear connecting shaft 114 and the baffle 109, respectively.
[0027] Specifically, the side plate 102 is equipped with two sets of swing arms 106, a rotating shaft 107, and a drive rod 108 to control the baffles 109 and contact plates 117 on both sides of the conveyor table 101. In use, the electric cylinder 104 is activated, and the output end of the electric cylinder 104 controls the push rod 105 to move. The push rod 105 slides out, causing the end of the swing arm 106 near the push rod 105 to slide on the slide groove of the push rod 105. This causes the end of the swing arm 106 away from the push rod 105 to drive the rotating shaft 107 to rotate on the bracket of the side plate 102. The rotating shaft 107 then drives the drive rod 108 to rotate. In turn, the drive rod 108 drives the baffles 109 and the rear connecting shaft 114 to move laterally through the slide groove. The rear connecting shaft 114 pushes or pulls the contact plate 117 to move through the rear buffer spring 116, realizing the sliding out and sliding in of the contact plate 117 and the baffle 109 on the conveyor table 101.
[0028] like Figures 3 to 5 As shown, the first end of the front limiting rod 110 is slidably disposed on the shaft of the baffle 109, and the second end of the front limiting rod 110 is slidably disposed on the shaft of the front connecting shaft 111.
[0029] A front buffer spring 113 is fixedly installed on the front connecting shaft 111. The front buffer spring 113 is sleeved on the front limiting shaft 112 and is also fixedly connected to the side plate 102.
[0030] A rear buffer spring 116 is fixedly installed on the contact plate 117. The rear buffer spring 116 is sleeved on the rear limit shaft 115 and is also fixedly connected to the rear connecting shaft 114.
[0031] Specifically, such as Figure 3 In the state shown, the baffle 109 is located inside the conveyor table 101, blocking the seedling tray in front, while the contact plate 117 is located outside the conveyor table 101. When the drive rod 108 rotates clockwise, the slide groove of the drive rod 108 drives the shaft of the baffle 109, thereby pushing the baffle 109 to move away from the conveyor table 101. Due to the restriction of the front limit rod 110, the shaft of the baffle 109 pushes one end of the front limit rod 110. The other end of the front limit rod 110 is sleeved on the shaft of the front connecting shaft 111. Thus, the front limit rod 110 pushes the front connecting shaft 111, and the front connecting shaft 111 then pulls the front limit shaft 112 to slide away from the conveyor table 101 on the side plate 102. The direction of the baffle 109 is restricted by the front limit rod 110, the front connecting shaft 111, and the front limit shaft 112, so as to prevent the baffle 109 from deflecting when the drive rod 108 pushes the baffle 109 because it is not restricted.
[0032] Simultaneously, another groove of the drive rod 108 pushes the rear connecting shaft 114 closer to the conveyor table 101, thereby pushing the rear buffer spring 116. The elastic force of the rear buffer spring 116 pushes the contact plate 117 closer to and in contact with the seedling tray behind it. The contact plate 117 pulls the rear limiting shaft 115, and the other end of the rear connecting shaft 114 pushes the rear limiting rod 118 to slide on the side plate 102 towards the conveyor table 101. The rear limiting rod 118 limits the deflection of the drive rod 108 when it pushes the rear connecting shaft 114. When the contact plate 117 contacts the seedling tray, the contact plate 117 is cushioned by a sponge and rubber layer to adapt to the side structure of the seedling tray. The rear connecting shaft 114 compresses the rear buffer spring 116 on the rear limiting shaft 115 to cushion the thrust of the rear connecting shaft 114. Thus, while maintaining the adjustment of the seedling tray, the seedling tray is protected from damage.
[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
