Problems solved by technology

Although the effect is good, it cannot be widely applied due to the high requirements on crop varieties and narrow application range.
[0005] In addition, the original threshing equipment did not make maximum use of the waste heat of the engine, resulting in a waste of energy

Embodiment 1

[0030] Such as figure 1 As shown, the temperature control threshing machine support body is a frame 3, a threshing drum 17 is installed on the frame 3, the drum shaft 9 is supported by a bearing 8 installed on the bearing seat 7, and the threshing drum 17 is supported by a top cover 5 and a concave sieve plate 18 Parcel, concave sieve plate is equipped with hot water outlet pipe 13 and waste heat exhaust pipe 15, and motor 16 is installed in frame 3 bottoms, and small V belt pulley 19 is equipped with on motor output shaft. Heating wires are also installed on the concave sieve plate, and the heating size of the heating wires can be adjusted by a voltage regulating switch (such as a thyristor voltage regulating switch).

[0031] Working principle, when the temperature-controlled threshing machine is working, the small pulley 19 of the engine 16 drives the large pulley 11 to rotate through the V-belt, and the large pulley 11 is connected to the drum shaft 9 through a key. When t...

Abstract

The invention discloses a threshing method based on waste heat utilization and a thresher based on the waste heat utilization. The thresher comprises a threshing cylinder, a concave sieve plate arranged below the threshing cylinder and an engine for driving the threshing cylinder; and is characterized in that the concave sieve plate is internally provided with a circulating cooling water pipe which is used for performing heat exchange with the inside of the concave sieve plate and cooling the engine; and the concave sieve plate is internally provided with an exhaust pipe which is used for performing heat exchange with the inside of the concave sieve plate and exhausting waste heat of the engine. The threshing method and the thresher make full use of waste heat of the engine, and are applicable to threshing of different crops by preheating and predrying materials in the threshing cylinder.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a threshing method based on waste heat utilization and a thresher based on waste heat utilization. Background technique [0002] At present, most threshing equipment at home and abroad use purely mechanical threshing, using the impact force of mechanical impact on crop ears, stems, fruit pods, etc., and the effect of combing force, to impact the joints of grains, forcing the grains to come out from the stalks and husks. The effect of this method on threshing different crop stalks is inconsistent. [0003] If the threshing drum on the mature rice-wheat combine harvester has a good threshing effect, but if the impact force is too small, the threshing will not be clean. Especially when the moisture content of crops is high, such as rain, dew, etc., it is more likely to affect the threshing effect. Conversely, if the set impact force is too large, the grain will be brok...
