To solve this problem, the present utility model provides the posts 121 on the guardrail 12, wherein only one end of the posts 121 is connected to the guardrail 12, and the other end is not connected to the bearing base 11. Thus, the binding string can be sleeved on the stub 121, and the fixing and the removing of the binding string are facilitated. The specific set density of the stubs 121 may be adjusted depending on the size and placement density of the harvesting basket.

Each of the sliding frames 13 includes a sliding bar 131 and a plurality of sliding columns 132, the middle of the sliding bar 131 is parallel to two sides of the bearing base 11 in the length direction, two ends of the sliding bar 131 are bent towards the bearing base 11 and smoothly connected to corners of the bearing base 11, the sliding columns 132 are connected between two sides of the bearing base 11 in the length direction and the middle of the sliding bar 131, the height of the sliding frame 13 is the distance between the bearing base 11 and the ground, and the heights of the two sliding frames 13 are the same so that the bearing base 11 can be horizontally placed on the ground.

The number of the slide columns 132 is 3 to 5 along the longitudinal direction of the slide frame 13. The sliding upright 132 is used for providing a stable support for the bearing base 11, preventing the sliding frame 13 from deforming, and the specific setting density can be adjusted according to practical situations. In addition, 1 to 3 bars may be provided and connected between the two runners 131, thereby further preventing deformation of the runner 13.

Please further refer to fig. 3-5. FIG. 3 is a front view of a self-unloading harvesting device according to a preferred embodiment of the present utility model (showing the roller frame not raised); fig. 4 is a front view of a self-unloading harvesting device according to a preferred embodiment of the present utility model (showing the roller frame raised); fig. 5 is a top view of a roller frame in a self-unloading harvesting device according to a preferred embodiment of the present utility model.

The utility model also provides a self-unloading harvesting device which comprises at least one self-unloading harvesting tray 1 and a trailer. The trailer comprises a bottom frame 4, a roller frame 5 and a hydraulic device 6, wherein the roller frame 5 is arranged on the bottom frame 4, the self-discharging harvesting tray 1 is arranged on the roller frame 5 and can slide along the length direction of the roller frame 5, the hydraulic device 6 is connected to the bottom frame 4 and corresponds to the front end of the roller frame 5, the hydraulic device 6 can lift the front ends of the bottom frame 4 and the roller frame 5 so that the roller frame 5 is inclined, and the self-discharging harvesting tray 1 automatically slides down from the roller frame 5.

The trailer comprises a locomotive 2 and a plurality of wheels 3, wherein the locomotive 2 is connected to the front end of the chassis 4, the wheels 3 are arranged on two sides of the locomotive 2 and two sides of the chassis 4, one end of a hydraulic device 6 is arranged on the locomotive 2, the other end of the hydraulic device is connected to the chassis 4, the locomotive 2 comprises a control device and a power device, the control device is connected to the wheels 3 and the hydraulic device 6 so as to control the running of the trailer and the lifting action of the hydraulic device 6, and the power device is connected to the wheels 3 and the hydraulic device 6 so as to provide power for the running of the trailer and the action of the hydraulic device 6 for lifting the chassis 4 and the roller frame 5.

The height of the underframe 4 is 40-50 cm. The height of the bottom frame 4 is not too high, otherwise, when the roller frame 5 is lifted, the inclination angle is too large, and the upper self-unloading harvesting tray 1 slides down too fast, so that the upper harvesting basket is dumped and scattered.

The length of the roller frame 5 is 420-440 cm, and the width of the roller frame 5 is 140-150 cm.

In the present utility model, the length and width dimensions of the roller frame 5 are matched with the number of the self-unloading picking tray 1 and the length and width dimensions. In an embodiment, if the size of the self-unloading harvesting tray 1 is 210cm in length and 120cm in width, 2 self-unloading harvesting trays 1 are placed on the roller frame 5 along the length direction, and the two sides of the roller frame 5 are 10cm wider than the self-unloading harvesting trays 1 (the roller frame 5 is not too wide than the self-unloading harvesting trays 1, so that the width of the trailer is too wide to damage the grape trellis when entering the grape), the length of the roller frame 5 is 420cm and the width of the roller frame 5 is 140cm. Of course, the length and width of the roller frame 5 can be adjusted according to practical situations, and the exemplary values in the embodiment are not limited.

The rear end of the roller frame 5 is provided with a detachable baffle. When the self-unloading harvesting tray 1 is placed on the roller frame 5, the detachable baffle is installed at the rear end of the roller frame 5, so that the self-unloading harvesting tray 1 can be prevented from accidentally sliding off from the rear end of the roller frame 5 due to inertia in the process that the trailer runs on the grape row. When the self-unloading harvesting tray 1 needs to be unloaded from the roller frame 5 in a normal sliding manner, the detachable baffle plate is detached in advance.

The self-unloading harvesting tray and the self-unloading harvesting device are suitable for vineyards where the harvesting trailer can enter the grape rows for harvesting. When the utility model is used, the following steps can be adopted:

1) When harvesting grapes, placing the self-unloading harvesting tray 1 on the trailer, placing a harvesting basket on the self-unloading harvesting tray 1, and driving the trailer into the grape row for harvesting;

2) Manually applying smaller picking boxes to carry out picking, pouring the picking boxes into a picking basket after the picking boxes are fully picked, and fixing the picking basket on the self-unloading picking tray 1 by using a binding rope after all the picking baskets are fully picked and stacked so as to prevent the picking basket from toppling over;

3) After harvesting, the trailer drives out the grape row, and the grape is transported to the site of the appointed loading and unloading vehicle;

4) After reaching the place of the loading and unloading vehicle, the front end of the roller frame 5 is lifted by utilizing the hydraulic device 6 of the trailer, the self-unloading harvesting tray 1 is automatically slid to the ground from the roller frame 5 by gravity together with a harvesting basket on the self-unloading harvesting tray 1, and the binding ropes do not need to be disassembled during the process;

5) After the self-unloading harvesting tray 1 is detached from the trailer, the binding ropes are untied (the binding ropes are not needed any more at the moment, the harvesting basket is provided with small clamping grooves and can be stacked together, and the forklift truck is stable), the self-unloading harvesting tray 1 is forked up together with the harvesting basket on the self-unloading harvesting tray 1 by the forklift truck, the self-unloading harvesting tray is lifted to the loading height of the truck, and the harvesting frame is manually conveyed from the tray to the cargo truck and is put into the basket;

6) Along with the continuous increase of loading height, the self-unloading harvesting tray 1 can be gradually lifted along with the height of the forklift until the height is the same as the loading height, and then the basket loading is taken out of the self-unloading harvesting tray 1, so that the aim of reducing labor intensity is fulfilled.
