Description

Technical Field

[0001] The utility model belongs to the technical field of grain transportation, in particular to a grain unloader capable of reducing material leakage. Background Art

[0002] After grain processing is completed, it needs to be transported, which is the physical flow of grain from the place of production to the place of receipt, including loading and unloading, storage, custody, packaging, transportation, distribution and information processing. After the grain is transported to the destination, it is generally transported by belt unloading equipment. Belt unloading equipment is not only suitable for horizontal transportation, but can also perform various movements such as rising and falling to adapt to different usage scenarios and terrain conditions.

[0003] The utility model patent with patent application publication number 201720667918.0 discloses that the seat and the vertical support are connected and fixed by an inclined bracket, and a number of belt sorting plates are provided on the inclined bracket, and the belt sorting plates support the mounting frame; a number of support rollers are provided on the mounting frame and the horizontal support, which are used to support the conveyor belt and divide the conveyor belt into a horizontal section and an inclined section; the conveyor belt in the inclined section passes through the belt sorting plates, and a measuring scale can be used to cumulatively weigh the grain on the conveyor belt to calculate the weight of the grain added to the granary, and the fan can easily separate the grain and impurities to improve the quality of the grain.

[0004] According to the above patent, there is a grain unloader that reduces material leakage. However, it still has shortcomings in actual use. The most obvious one is that when the current conveyor belt is in use, a cleaning plate is usually used to clean the impurities on the surface of the conveyor belt. However, when there are stubborn stains or highly adhesive grains on the conveyor belt, it is more difficult to clean the surface of the conveyor belt. The residual impurities will increase the running resistance, resulting in a slower conveying speed, thereby reducing the working efficiency of the grain unloader. For this reason, we propose a grain unloader that reduces material leakage. Utility Model Content

[0005] The purpose of the present invention is to provide a grain unloader capable of reducing material leakage, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose of the invention, the present invention provides the following technical solutions:

[0007] The present application is specifically as follows: a grain unloading machine for reducing material leakage, comprising: a frame and a mounting frame, the mounting frame being divided into two groups and fixedly connected to the bottom of the frame, the frame being provided with a transport member for conveying grain and an isolation member for reducing material leakage; a rotating shaft is rotatably connected at one end between the two groups of mounting frames, a cleaning brush is fixedly connected to the outer wall of the rotating shaft, a support frame is fixedly connected at the other end between the two groups of mounting frames, the inner cavity of the support frame is rotatably connected to a reciprocating screw, the outer wall of the reciprocating screw is connected to a movable block through a ball thread, the top of the movable block is fixedly connected to a scraper, the scraper is used in conjunction with the transport member, the mounting frame is provided with a driving member for driving the rotating shaft and the reciprocating screw to rotate synchronously, and a collecting member for storing impurities is provided between the two groups of mounting frames.

[0008] As a preferred technical solution of the present application, the transport member includes a conveyor belt, which is rotatably arranged in the inner cavity of the frame, and the bottom of the frame is fixedly connected to a support leg.

[0009] As a preferred technical solution of the present application, the isolation member includes a baffle, which is fixedly connected to the top of the frame.

[0010] As a preferred technical solution of the present application, the driving member includes a U-shaped frame and two groups of connecting rods. The U-shaped frame is fixedly connected to a side wall of the mounting frame. The two groups of connecting rods are rotatably connected to the inner cavity of the U-shaped frame. The two groups of connecting rods are fixedly connected to the rotating shaft and the reciprocating screw respectively. The side wall of the U-shaped frame is fixedly connected to a motor for driving the connecting rod to rotate. The two groups of connecting rods are provided with transmission members for making the two groups of connecting rods rotate synchronously.

[0011] As a preferred technical solution of the present application, the transmission member includes two sets of synchronous wheels, the two sets of synchronous wheels are fixedly connected to the outer side walls of the two sets of connecting rods, and a synchronous belt is provided between the two sets of synchronous wheels.

[0012] As a preferred technical solution of the present application, the collecting part includes a guide hopper, which is fixedly connected between two sets of mounting frames. The discharge port of the guide hopper is fixedly connected to a storage box, and a vacuum cleaner is embedded in the side wall of the storage box.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In the scheme of this application:

[0015] 1. By setting a power part to drive the rotating shaft and the reciprocating screw to rotate synchronously, the cleaning brush is driven to rotate by the driving shaft, and the cleaning brush cleans the surface of the conveyor belt. At the same time, the reciprocating screw drives the movable block and the scraper to move back and forth horizontally. The reciprocating movement of the scraper makes the scraper constantly contact with the surface of the conveyor belt and generate friction during the reciprocating movement, which helps to peel off the stains and residues on the conveyor belt from the surface, achieving better cleaning effect, thereby reducing the residual impurities that increase the running resistance and cause the conveying speed to slow down, thereby improving the working efficiency of the grain unloader.

[0016] 2. By setting up a guide hopper, a storage box and a vacuum cleaner, the vacuum cleaner will suck the impurities into the guide hopper, and the impurities will be diverted to the storage box through the storage box, so as to facilitate the collection of impurities and convenient use. By setting a baffle in the frame, the baffle can be used to isolate the grain on the conveyor belt to reduce the occurrence of leakage. BRIEF DESCRIPTION OF THE DRAWINGS
