Description

Conveying and lifting bagging rice thresher

Technical field:

The utility model relates to agricultural machinery, in particular to a conveying, lifting and bagging rice thresher with simple structure, which integrates threshing, screening, automatic conveying, lifting and bagging.

Background technique:

At present, under the situation that large-scale combine harvesters cannot be realized in the hilly area of the south, people have invented various small semi-automatic rice threshers. The shaking screen below is used for screening, and then discharged from the grain exit, or through the grain exit and then through the spiral auger or keel lifting plate or blower to realize automatic bagging. The structure of the lifting and bagging part of this rice thresher is relatively complicated. The millet first goes to the grain collector, and then is sent to the pipeline type lifting device for lifting and bagging. It is easy to stick to the inner wall of the lifting pipe or the lifting plate during the lifting process, and the lifting and transportation are not smooth, and the automatic bagging will be limited in use.

Utility model content:

The purpose of this utility model is to provide the public with a simple structure, which integrates threshing, screening, automatic conveying, lifting and bagging, and the automatic lifting and transportation is not restricted by the weather and the moisture content of the millet. thresher.

The utility model comprises a frame, an outer cover, a threshing drum fixed above the front end of the frame, a shaker box hanging on the frame behind the front support under the threshing drum, a power source fixed on the frame, a transmission device and a lifting device. Conveying device, the feeding end of the lifting and conveying device corresponds to the grain outlet on one side of the shaking screen box. One end is the feed end, and the higher end is the discharge end. Two drive rollers, one low and one high, are mounted on the bracket on one side of the frame. One of the drive rollers is equipped with a pulley at the end, and the conveyor belt is set on the two drive rollers. The lower end and both sides of the conveyor belt are respectively provided with barriers, and the lifting transport device is linked by the pulley at the end of one of the transmission rollers and the power source.

Considering that the humidity of the millet laid in the rainy day or in the morning is too high, and the millet is easy to stick to the conveyor belt during the lifting and transportation process, a scraper that sticks to the surface of the conveyor belt and also makes the mouth of the valley is installed under the discharge end of the lifting device. The scraper is fixed on the bracket below the drive roller.

In order to make the conveyor belt convey more smoothly and smoothly between the two transmission rollers, a conveying sleeve is also provided between the two transmission rollers below the conveyor belt, which can also prolong the service life of the conveyor belt.

The lifting transport device of the utility model has an open structure, so it can be used when there is a temporary light rain or rush to harvest after the rain, or when the rice ears contain a lot of water due to morning dew, and is not affected by the weather, and has a simple structure, small size and light weight. , integrating threshing, screening, automatic lifting and bagging, has many functions and high work efficiency, which can greatly save labor and labor intensity.

Description of drawings:

Fig. 1 is a schematic view of the structure on the left side of the utility model;

Fig. 2 is a schematic diagram of the structure on the right side of the utility model.

In the figure: 1 frame, 2 outer cover, 3 threshing drum, 4 shaking screen box, 5 power source, 6 scraper, 7 transmission roller, 8 conveyor belt, 9 blocking board, 10 conveying casing, 11 grain outlet, 12 tray Sieve shaft, 13 belt pulleys.

Detailed ways:

The frame 1 of the utility model, the outer cover 2, the threshing drum 3 fixed on the top of the front end of the frame 1, the shaker box 4 hanging on the frame behind the front support under the threshing drum 3, and the threshing drum 4 fixed on the frame 1 The structure and connection relationship of the power source 5 and the transmission device are prior art. The connection and transmission of the shaking screen box 4 can be realized by the screen support shaft 12 connected to the eccentric position of one end of the threshing drum 3, or by a rocker connected to the eccentric position of one end of the threshing drum 3. The grain inlet end of the lifting transport device corresponds to the grain outlet 11 on one side of the shaking screen box 4 . The difference is that the lifting transport device is composed of a transmission roller 7, a conveyor belt 8 and a fence 9, which are installed obliquely on one side of the frame 1 near the rear end, the lower end is the feeding end, and the higher end is the discharging end. In this way, baskets or woven bags can be used to directly and automatically pack bags after the conveying and lifting reaches a certain height, so as to achieve the purpose of automatic conveying, lifting and bagging; the two driving rollers 7 of the lifting and transporting device are equipped with one low and one high on one side of the frame 1 On the bracket, the end of the transmission roller 7 at the feed end is provided with a pulley 13; the conveyor belt 8 is set on the two transmission rollers 7, and the conveyor belt 8 generally adopts a canvas belt, and can also be set on the surface of the general belt to be uneven or uneven. Set some obstacles, such as partitions, so that the millet can be smoothly lifted on the conveyor belt; a conveying sleeve 10 is installed between the two driving rollers 7 below the conveying belt 8, and the conveying sleeve 10 can rotate with the driving roller 7 And rotate, can reduce the load-bearing capacity of conveyer belt 8, reduce and the frictional force between two end drive rollers 7, thereby make conveyer belt 8 convey more stable, smoothly between two drive rollers 7; And both sides are provided with baffle plate 9 respectively, so that stop millet and fall from the lower end and both sides of conveyer belt 8 during transportation;

The inventor considers that the humidity of the millet laid down in rainy days or in the morning is too high, and the millet is easy to stick to the conveyor belt 8 in the process of lifting and transporting. Scraper 6, scraper 6 is fixed on the support below drive roller 7, also can be made valley mouth.
