[0022] The structure of the utility model is further described below with reference to the accompanying drawings and through embodiments. It should be noted that the embodiments are descriptive rather than restrictive.

[0023] A grain recovery and tipping hopper device, see Figure 1-Figure 5 The invention point is: it includes a grain hopper body 1, a grain unloading driving cylinder 2, a diagonal bracing beam 3, and a grain hopper bracket.

[0024] Grain hopper bracket:

[0025] The grain hopper support is used to support the grain hopper body, which is installed on the frame of the harvester. The grain hopper support is composed of a bottom frame 5 and a side frame 6. The bottom frame is fixedly connected to the frame of the harvester through bolt connectors. Long slot holes 5.1 along the left and right directions are arranged on the front and rear beams of the bottom frame, close to the inside of the harvester. The inner and outer ends of the front and rear beams of the bottom frame are provided with upwardly extending hinged seats. The side frame includes front and rear equal-length vertical beams 6.2 and an upper horizontal beam 6.1 connecting the upper ends of the two vertical beams. An inwardly extending hinged seat is arranged near the upper ends of the two vertical beams. The lower end of the front vertical beam and the lower end of the rear vertical beam are respectively connected to the hinged seat at the outer end of the front horizontal beam of the bottom frame and the hinged seat at the outer end of the rear horizontal beam of the bottom frame through a hinge shaft to form a relatively rotatable connection.

[0026] Grain bucket body:

[0027] The grain hopper body is welded by profiles and guard plates, and is a closed lower end and open upper end structure. To ensure the accuracy of the grain unloading position and reduce interference with other parts of the harvester, the upper end 1.1 of the grain hopper body adopts an oblique shape with a high outer side and a low inner side, and the lower part 1.2 of the grain hopper body adopts a trapezoidal shape with a large upper part and a small lower part.

[0028] The grain hopper body is integrally arranged at an upper position in the bottom frame. The middle part of the outer side of the grain hopper body is rotatably connected with the upper crossbeam of the side frame through two hinge assemblies 8 coaxially arranged along the front-back direction, forming a turning center 9 of the grain hopper body.

[0029] An oil cylinder connecting seat 7 is respectively fixed to the outer middle portion of the front side wall and the rear side wall of the grain hopper body.

[0030] Grain unloading drive cylinder:

[0031] There are two grain unloading driving cylinders, which are respectively arranged at the front end and the rear end of the grain hopper body. The upper cylinder rod end of the grain unloading driving cylinder located at the front end is rotatably connected to the cylinder connecting seat on the front side of the grain hopper body through a hinge shaft, and the lower cylinder barrel end of the grain unloading driving cylinder located at the front end is rotatably connected to the hinge seat at the inner end of the front cross beam of the bottom frame through a hinge shaft; the upper cylinder rod end of the grain unloading driving cylinder located at the rear end is rotatably connected to the cylinder connecting seat on the rear side of the grain hopper body through a hinge shaft, and the lower cylinder barrel end of the grain unloading driving cylinder located at the rear end is rotatably connected to the hinge seat at the inner end of the rear cross beam of the bottom frame through a hinge shaft.

[0032] By extending the two grain unloading drive cylinders at the same time, the grain hopper body can be turned up and outward around the turning center. When the upper end of the grain hopper body is rotated to a downward position, the grain can be unloaded smoothly and quickly.

[0033] Diagonal bracing beam:

[0034] There are two diagonal bracing beams, which are respectively arranged at the front end and the rear end of the grain hopper body. The upper end of the diagonal bracing beam at the front end is connected to the inner end of the hinge seat on the front vertical beam through a hinge shaft, and the lower end of the diagonal bracing beam at the front end is connected to the long slot hole at the front end of the bottom frame through a sliding pin 4 to slide along the left and right direction. The upper end of the diagonal bracing beam at the rear end is connected to the inner end of the hinge seat on the rear vertical beam through a hinge shaft, and the lower end of the diagonal bracing beam at the rear end is connected to the long slot hole at the rear end of the bottom frame through a sliding pin to slide along the left and right direction.

[0035] The diagonal bracing beam plays a role in strengthening the grain hopper support and flipping, thereby ensuring the structural stability of the entire grain recovery and flipping grain hopper device.

[0036] In the above structure, the left and right sliding connection between the diagonal support beam and the corresponding cross beam of the bottom frame is not limited to the matching structure of the sliding pin and the long sliding groove, and can also adopt the matching form of the sliding block and the sliding rail, etc., as long as the requirements of relative sliding of the two within the set travel range can be met.

[0037] The working principle of the grain recovery and flipping hopper device is as follows:

[0038] During the process of harvesting corn cobs and stalks, the grain hopper is vertically arranged on the inner side of the side frame of the grain hopper bracket, and a gap of about 2mm is ensured between the lower end of the grain hopper and the frame of the harvester. A visual observation window is installed on the front side wall of the grain hopper body to observe the grain accumulation position in the grain hopper at any time. When the grain accumulation in the grain hopper body is close to the oblique position at the upper end, the two grain unloading drive cylinders are started, and the cylinder rods are extended, first driving the grain hopper and the side frame of the grain hopper bracket to synchronously rotate around the front crossbeam of the bottom frame and the hinged axial end of the outer end of the rear side wall The machine rotates outward to avoid the fan outlet above the harvester. At this time, the upper ends of the two diagonal bracing beams rotate around the corresponding hinge shafts, and the lower ends slide outward in the corresponding long slots through the sliding pins. When sliding to the outermost position of the long slots, a stable triangular support structure is formed through the bottom frame, side frames and diagonal bracing beams. At this time, the side frames stop rotating, and the cylinder rod of the grain unloading drive cylinder continues to extend. The grain hopper body flips upward and outward around its flip center, so that the upper end of the grain hopper body flips to the lower part, and the grain is unloaded smoothly and quickly through the upper port. When the grain unloading is completed, the cylinder rods of the two grain unloading drive cylinders are gradually retracted, first completing the grain hopper body to flip back to the inside of the side frame, and then the grain hopper body rotates to the vertical position with the side frame to complete the entire grain unloading operation.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
