Abstract
Description
Technical Field
[0001] This utility model belongs to the field of combine harvester technology, and in particular relates to a wheat combine harvester re-threshing and cleaning device. Background Technology
[0002] A wheat combine harvester is an agricultural machine used to harvest wheat. It has functions such as harvesting, threshing, and cleaning. It can complete crop harvesting and preliminary processing in one go, significantly improving production efficiency. Its core task is to ensure that the grain coming out of the combine harvester is clean, dry, and plump, while separating out impurities.
[0003] In the process of using some existing wheat combine harvesters, when the impurities are thrown onto the cleaning screen, they tend to concentrate in the middle of the screen surface, resulting in low screen surface utilization and wasted air volume on both sides. Moreover, the airflow generated by traditional blowers is unevenly distributed in the width direction of the screen surface, which can easily lead to localized uncleanliness or loss of grains, affecting cleaning efficiency. In view of this, we propose a wheat combine harvester re-threshing and cleaning device. Utility Model Content

[0021] The beneficial effects of this utility model are:
[0022] 1. This wheat combine harvester's double-threshing and cleaning device, through the cooperation of components such as the collecting plate and the blowing plate, firstly, the collecting plate can draw air to remove debris floating between the inclined plate and the vibrating plate, allowing the debris to be cleaned away with the air. The blowing plate can blow air to allow the wheat to float over the break in the vibrating plate, while heavier debris will fall down from the break, and lighter debris will float higher, thus better cleaning the wheat and solving the problem of uneven airflow distribution affecting efficiency.
[0023] 2. This wheat combine harvester's threshing and cleaning device, through the cooperation between components such as the inclined plate and the vibrating screen plate, allows impurities falling from the break of the vibrating plate to slide out, preventing them from accumulating inside the protective shell. The vibrating screen plate allows the wheat stalks that have been rubbed by the textured rollers to vibrate, causing the wheat grains on the stalks to be shaken off, thus ensuring cleaner threshing. It is very easy to use. Attached Figure Description

Detailed Implementation
[0031] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0032] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0033] Example 1: This example provides a wheat combine harvester threshing and cleaning device, including a protective shell 1, an inclined plate 2 connected inside the protective shell 1, a vibrating plate 3 installed inside the protective shell 1, an inclined plate 4 installed inside the protective shell 1, and a vibrating screen plate 5 installed inside the protective shell 1.
[0034] The bottom surface of the inclined plate 2 is connected to the collection shell 6, the inside of the collection shell 6 is slidably connected to the exhaust plate 7, and the inside of the collection shell 6 is connected to the exhaust pipe 8.
[0035] The protective shell 1 has an internal air blowing plate 9, an internal air blowing pipe 10, an internal air blowing net 11, and a support frame 12 installed on the outer surface of the air blowing pipe 10.
[0036] The protective shell 1 restricts the position of the inclined plate 2, preventing it from moving. Threshed wheat falls onto the inclined plate 2 and slides down its slope onto the vibrating plate 3. Both the vibrating plate 3 and the vibrating screen plate 5 are connected to a vibrating motor. The motor vibrates the vibrating plate 3 and screen plate 5, causing the material above to slide down. The material on the inclined plate 2 slides down the slope onto the vibrating plate 3 and moves towards its break point as the plate vibrates. The inclined plate 2 restricts the position of the collecting shell 6, which in turn restricts the extraction... The direction of movement of the air deflector 7, the other end of the exhaust pipe 8 is connected to the exhaust device, so that the air deflector 7 can suck away the floating impurities. The protective shell 1 will restrict the position of the air blower 9. The other end of the air blower 10 will be connected to the air blowing device, so that the air blower 9 can blow out air. The air blown out by the air blower 9 will make the wheat passing through the vibration plate 3 float past the break, let the impurities heavier than the wheat fall down, and let the impurities that are easy to lift the wheat float up. The barrier net 11 will protect the impurities and prevent them from falling into the air blower 9. The support frame 12 will provide support for the air blower 10.
[0037] Example 2: This example provides a wheat combine harvester threshing and cleaning device. In addition to the technical solutions of the above examples, it also has the following technical features: a textured roller 13 is installed inside the protective shell 1, and a filter plate 14 is connected inside the protective shell 1.
[0038] The protective shell 1 restricts the position of the textured roller 13, which can rotate. The rolling of the textured roller 13 rubs the wheat, causing the wheat grains to separate from the wheat. The wheat grains then fall from the filter plate 14 onto the inclined plate 2.
[0039] Example 3: This example provides a wheat combine harvester re-threshing and cleaning device. In addition to the technical solutions of the above examples, it also has the following technical features: a telescopic plate 15 is slidably connected inside the collection shell 6, and the outer surface of the telescopic plate 15 is connected to the inside of the exhaust plate 7.
[0040] The collection shell 6 restricts the direction in which the telescopic plate 15 can move. The movement of the telescopic plate 15 will move the exhaust plate 7, allowing the height of the exhaust plate 7 to be adjusted, thus making it easier for the exhaust plate 7 to collect impurities.
[0041] Example 4: This example provides a wheat combine harvester threshing and cleaning device. In addition to the technical solutions of the above examples, it also has the following technical features: an electric push rod 16 is installed inside the collection shell 6, and the output end of the electric push rod 16 is connected to a transmission plate 17.
[0042] The collection shell 6 restricts the position of the electric push rod 16, which moves the transmission plate 17 when it is started.
[0043] Example 5: This example provides a wheat combine harvester re-threshing and cleaning device. In addition to the technical solutions of the above examples, it also has the following technical features: the outer surface of the transmission plate 17 is slidably connected to the outer surface of the telescopic plate 15, and the outer surface of the transmission plate 17 is slidably connected to the inside of the collection shell 6.
[0044] The movement of the transmission plate 17 will move the telescopic plate 15, thereby facilitating the adjustment of the position of the transmission plate 17.
[0045] Example 6: This example provides a wheat combine harvester re-threshing and cleaning device. In addition to the technical solutions of the above examples, it also has the following technical features: the outer surface of the exhaust pipe 8 is slidably connected to the inside of the protective shell 1, and the outer surface of the blower pipe 10 is slidably connected to the inside of the protective shell 1.
[0046] Among them, the exhaust pipe 8 and the blower pipe 10 are both flexible hoses that can be bent.
[0047] Example 7: This example provides a wheat combine harvester re-threshing and cleaning device. In addition to the technical solutions of the above examples, it also has the following technical features: the outer surface of the support frame 12 is connected to the inside of the protective shell 1, and the inside of the protective shell 1 is provided with a discharge port 18.
[0048] The protective shell 1 restricts the position of the support frame 12. Multiple discharge ports 18 are provided inside the protective shell 1, allowing materials and impurities to be discharged from different positions.
[0049] Working principle: In use, wheat is first fed to the textured roller 13, which rubs the wheat. The rubbed wheat grains pass through the filter plate 14 and fall onto the inclined plate 2. The wheat grains fall onto the vibrating plate 3 along the slope of the inclined plate 2. Under the vibration of the vibrating plate 3, the wheat grains move towards the break. When passing the break, the blower pipe 10 blows air to the blower plate 9, which blows the wheat up and floats it over the break. Heavier impurities fall onto the inclined plate 4 and are discharged from the outlet 18 along with the inclined plate 4. Lighter impurities are sucked away by the suction plate 7. Then the wheat grains pass through the break and are discharged from the outlet 18 at the other end of the vibrating plate 3.
