Embodiment 1

[0069] The half-feed combine harvester threshing device of the present embodiment comprises:

[0070] Rack 1;

[0071] The threshing drum part 2 is arranged horizontally in the frame 1;

[0072] The first sieve plate part 3 is horizontally arranged under the threshing drum part 2, and the first sieve plate part 3 cooperates with the threshing drum part 2 to sieve the grain in the rice material;

[0073] Cleaning room 4, which is arranged below the first sieve plate part 3, and the cleaning room 4 cleans the grains in the first sieve plate part 3 and sieves off the materials and discharges the miscellaneous materials from the bottom of the cleaning room 4;

[0074] The miscellaneous conveying auger 5, which is horizontally arranged under the cleaning chamber 4, transfers the miscellaneous materials discharged from the cleaning chamber 4 to the outside of the frame 1;

[0075] Also includes:

[0076] The re-extraction drum part 6 is horizontally arranged between the threshing...

Embodiment 2

[0087] The semi-feed combine harvester threshing device of this embodiment is further improved on the basis of embodiment 1, the threshing drum part 2 is a bow-toothed drum, and the first sieve plate part 3 is a concave plate sieve.

[0088] Such as image 3 As shown, the bow-toothed drum, that is, a number of bowed teeth 20 are formed on the side wall of the drum, which can continuously brush and beat the rice material during rotation, thereby promoting the grain to come out, and the concave plate sieve can increase the amount of rice fed. The area where the material receives the action of combing and brushing can improve the efficiency of threshing.

Embodiment 3

[0090] The half-feed combine harvester threshing device of the present embodiment is further improved on the basis of embodiment 2, and the re-extraction drum part 6 includes:

[0091] Intermediate shaft 60, which is rotatably connected with frame 1;

[0092] A circular tube 61, which is sleeved and fixed on the outer wall of the intermediate shaft 60;

[0093] The auger blade 62 is fixed on the outer wall of the circular tube 61 in a spiral manner;

[0094] Cutter teeth 63, which have several, are all connected to the outer edge of the auger blade 62 and stretch out;

[0095] The axis of the intermediate shaft 60 is parallel to the axis of the threshing cylinder part 2 .

[0096] Such as Image 6 with Figure 7 As shown, the intermediate shaft 60 of the re-rolling drum part 6 of this embodiment is rotatably connected to the frame 1, one end of the intermediate shaft 60 is rotatably connected to the frame 1 through the bearing seat structure, and the other end is also rota...

Abstract

The invention discloses a half-feeding combine harvester threshing device and a threshing method, and belongs to the field of grain threshing. The device comprises a rack, a threshing cylinder part, a first sieve plate part, a cleaning chamber, an impurity conveying auger and further comprises a re-threshing cylinder part, a second sieve plate part and an impurity lifting auger, wherein the threshing cylinder part is horizontally arranged in the rack; the first sieve plate part is horizontally arranged below the threshing cylinder part; the cleaning chamber is arranged below the first sieve plate part; the impurity conveying auger is horizontally arranged below the cleaning chamber; the re-threshing cylinder part is horizontally arranged between the threshing cylinder part and one side surface of the rack; the second sieve plate part is horizontally arranged below the re-threshing cylinder part, and the second sieve plate part is matched with the re-threshing cylinder part to sieve grains in the impurity materials; and the impurity lifting auger is obliquely fixed to one side face of the rack, a feeding port of the impurity lifting auger communicates with a discharging port of the impurity conveying auger, and a discharging port of the impurity lifting auger conveys the impurity materials to the re-threshing cylinder part. According to the half-feeding combine harvester threshing device and the threshing method, on the premise that the length of the threshing cylinder part is not increased and the occupied space of equipment is not increased, the total threshing time of the device is prolonged, and the threshing rate is improved.

Description

technical field [0001] The invention belongs to the technical field of grain threshing, and more specifically relates to a half-feed combine harvester threshing device and a threshing method. Background technique [0002] In recent years, with the continuous improvement of people's living standards, millet, wheat, etc., as high-quality grains, have more and more market demand, but millet is difficult to thresh clean crops, and most of the combine harvesters in the market are longitudinal flow type Generally, the threshing rate of the harvester is improved by increasing the length of the threshing drum. Although a longer threshing drum can increase the threshing time of the crops and obtain better threshing effects, when facing a large number of crops fed, the threshing device The feeding inlet is very prone to blockage, resulting in increased threshing load, unclean disposal of residues and even breakage of the threshing drum shaft. [0003] At present, the residues generat...
