The description herein is only based on the preferred embodiments of the utility model, and other modes capable of realizing the utility model can be conceived by those skilled in the art on the basis of the preferred embodiments, and the other modes also fall within the scope of the utility model.

[0027] Reference Figures 1-4 The embodiment provides a seedling raising and disc collecting machine, which comprises a push disc mechanism 100 and a conveying disc mechanism 200, the conveying disc mechanism 200 is provided with two groups and is located at the two sides of the push disc mechanism 100 respectively; the conveying disc mechanism 200 conveys the seedling tray to the push disc mechanism 100. The push disc mechanism 100 is provided with a first block group 110 and a second block group 120 at the two sides close to the conveying disc mechanism 200 respectively, the first block group 110 and the second block group 120 are connected through a linkage mechanism, and the linkage mechanism is connected with a driving member 130; when the first block group 110 is located at a first working position, the second block group 120 is located at a second working position; when the first block group 110 is located at the second working position, the second block group 120 is located at the first working position. The linkage mechanism can make the first block group 110 and the second block group 120 move simultaneously and move to different working positions. When the first block group 110 or the second block group 120 is located at the first working position, i.e. the position where the first block group 110 or the second block group 120 stands up and exceeds the bearing surface of the push disc mechanism 100 is the first working position, the seedling tray conveyed by the conveying disc mechanism 200 on the corresponding side can be blocked and positioned on the push disc mechanism 100, so that the seedling tray is stably stayed on the push disc mechanism 100 and prevented from falling due to continuous movement. Correspondingly, the second block group 120 or the first block group 110 located at the second working position can ensure that the seedling tray is smoothly transferred from the conveying disc mechanism 200 to the push disc mechanism 100, when the second block group 120 or the first block group 110 is located at the second working position, the second block group 120 or the first block group 110 lies on the bearing surface of the push disc mechanism 100 and does not exceed the bearing surface of the push disc mechanism 100. The linkage of the first block group 110 and the second block group 120 can reduce the driving member 130 and the driving control design, simplify the structure design and control logic design, and save costs. Moreover, the mechanical structure design of the linkage mechanism is more durable and more cost-effective than the control logic design.

[0028] In some embodiments, the linkage mechanism comprises a linkage assembly, and the first block group 110 and the second block group 120 are connected with the linkage assembly. The linkage assembly is driven to move linearly by the driving member 130, and the linear movement of the linkage assembly drives the first block group 110 and the second block group 120 to switch between the first working position and the second working position. The linkage assembly has good movement consistency, can accurately switch the first block group 110 and the second block group 120 between the first working position and the second working position, and can ensure the synchronous movement of the first block group 110 and the second block group 120.

[0029] Specifically, as shown in Figure 3 the linkage assembly comprises a first linkage 112, a second linkage 122, and an intermediate linkage 123. The first linkage 112 and the second linkage 122 are distributed on both sides of the push disc mechanism 100, the first block group 110 is rotationally connected with the first linkage 112, and the second block group 120 is rotationally connected with the second linkage 122. The intermediate linkage 123 connects the first linkage 112 and the second linkage 122, and the output end of the driving member 130 is connected with the intermediate linkage 123. The driving member 130 works to drive the intermediate linkage 123 to move linearly, and under the connection relationship of the intermediate linkage 123, the driving member 130 can drive the first linkage 112 and the second linkage 122 to move linearly, thereby driving the first block group 110 and the second block group 120 to rotate. After the rotating action of the first block group 110 and the second block group 120 is completed, they are stopped at the first working position or the second working position. It should be noted that the driving member 130 is one of a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. The first linkage 112 and the second linkage 122 are arranged along the length direction of the push disc mechanism 100, and the intermediate linkage 123 is arranged perpendicular to the length direction of the push disc mechanism 100.

[0030] Further, the first block group 110 comprises a plurality of first block units 111, and the plurality of first block units 111 are arranged alternately on the first linkage 112 and rotationally connected with the first linkage 112. The alternate arrangement can provide sufficient rotating space for the first block units 111. The distance between two adjacent first block units 111 is not greater than the side length of the seedling tray, so that the seedling tray can be blocked to prevent it from falling from the interval between the two adjacent first block units 111. The second block group 120 comprises a plurality of second block units 121, and the second block units 121 are arranged correspondingly with the first block units 111. The second block units 121 can keep the corresponding movement track of the first block units 111, and when the seedling tray is transported from the conveying disc mechanism 200 on the side opposite to the second block units 121, the second block units 121 can also reliably block the seedling tray.

[0031] In some embodiments, as shown in Figure 2As shown, the pushing disc mechanism 100 includes a plurality of movable rollers 140 arranged at intervals, the axial direction of the movable rollers 140 is parallel to the length direction of the first connecting rod 112. The movable rollers 140 can assist the seedling tray to continue to slide when the seedling tray is conveyed from the conveying disc mechanism 200 to the pushing disc mechanism 100, and the seedling tray is completely stopped on the pushing disc mechanism 100, facilitating the subsequent conveying work of the seedling tray. The first block group 110 and the second block group 120 are arranged in the intervals between the two outermost movable rollers 140 of the pushing disc mechanism 100, and the first block group 110 or the second block group 120 is located above the top surface of the movable roller 140 when it is in the first working position, and the first block group 110 or the second block group 120 is lower than or flush with the top surface of the movable roller 140 when it is in the second working position. The first block group 110 or the second block group 120 can accurately block the stopping position of the seedling tray to prevent the seedling tray from falling.

[0032] In order to realize the switching of the first block unit 111 and the second block unit 121 between the first working position and the second working position through a simple rotating action, in some embodiments, as shown in Figure 4 As shown, the first block unit 111 includes a first blocking part 1111 and a first bending part 1112 connected with each other, and a first rotating hole 1113 is arranged at the connection position of the two parts, and the first block unit 111 is rotatably connected with the first connecting rod 112 through the first rotating hole 1113. When the first block unit 111 is in the first working position, the first blocking part 1111 is erected above the top surface of the movable roller 140. When the first block unit 112 is in the second working position, the first blocking part 1111 lies in the gap of the movable roller 140 and does not exceed the top surface of the movable roller 140. It can be understood that the structure of the second block unit 121 is the same as that of the first block unit 111, and the bending direction of the second block unit 121 is opposite to that of the first block unit 111 when arranged, so that the first block unit 111 is in the first working position and the second block unit 121 is in the second working position.

[0033] In some embodiments, as shown in Figure 2As shown, the pushing disc mechanism 100 is provided with a pushing disc assembly for pushing the seedling tray out from one side of the pushing disc mechanism 100. Specifically, the pushing disc assembly comprises a power member, a driven member 151 and a pushing disc stopper 152, the pushing disc stopper 152 is fixed on the driven member 151, the driven member 152 drives the pushing disc stopper 152 to move along the axial direction of the movable roller 140, and the top end of the pushing disc stopper 152 is higher than the top surface of the movable roller 140. When the pushing disc stopper 152 moves with the driven member 151, the pushing disc stopper 152 pushes the seedling tray out from one side of the length direction of the pushing disc mechanism 100. It can be understood that the power member is an electric motor, and the driven member 151 is a driven chain or a driven belt. In this embodiment, the driven chain is used, and the driven chain can drive the pushing disc stopper 152 to move up and down along the length direction of the pushing disc mechanism 100. When the pushing disc stopper 152 moves to the upper side of the pushing disc mechanism 100, the pushing disc is pushed out.

[0034] In some embodiments, the conveying disc mechanism 200 is provided with a plurality of conveying belt groups, each conveying belt group comprising two conveying belts 210, and the distance between the two conveying belts 210 is not greater than the distance between two adjacent first block units 111. Considering that the distance between two adjacent first block units 111 is not greater than the side length of the seedling tray, it can be seen that the distance between the two conveying belts 210 is not greater than the side length of the seedling tray, so the seedling tray can be stably placed on the two conveying belts 210, avoiding the situation that the seedling tray falls off from the conveying belts 210. Further, the surface of the conveying belt 210 is provided with an anti-skid structure, which can increase the friction between the surface of the conveying belt 210 and the bottom of the seedling tray, so that the seedling tray is more stable on the conveying belt 210.

[0035] It should be noted that, in some embodiments, the input end of the conveying disc mechanism 200 is provided with a tray lifting assembly 220, and the tray lifting assembly 220 is correspondingly arranged with the conveying belt group. The tray lifting assembly 220 can conveniently lift the seedling tray from the field and send it to the conveying belt group, reduce the lifting resistance, and improve the lifting efficiency. The bottom surface of the end of the tray lifting assembly 220 has a certain slope, which facilitates the insertion of the tray lifting assembly 220 into the bottom of the seedling tray.
