Description

Technical Field

[0001] The invention relates to the technical field of grain separation devices, in particular to a rice transverse axis reciprocating flow direction double-drum processing device. Background Art

[0002] Rice is one of China's main food crops and has a long-term stable and important position in China's food structure. The latest data shows that rice accounts for about 30% of China's total grain, and about 60% of the people use it as a staple food. Therefore, as a major food crop, rice is extremely critical to global and even national food security. As a key food crop, rice has also been innovated in harvesting technology. China's rice combine harvester technology has made significant progress in recent years, but there is still room for improvement, especially in improving harvesting efficiency. By optimizing the grain separation device and adjusting the grain separation gap, the impact on rice can be reduced and the operation quality can be improved, which plays a key role in promoting the scale and modernization of rice production.

[0003] The grain separation device is the core of the rice combine harvester, and its performance directly affects the overall working effect of the machine. The existing technologies related to grain separation equipment include the following:

[0004] 1. A double-drum threshing device with publication number CN107318389A discloses a frame, a main threshing drum, an auxiliary threshing drum, a main separation screen, an auxiliary separation screen, a power device, a threshing cover and a receiving hopper. The main threshing drum and the auxiliary threshing drum are arranged in parallel on the frame. The main separation screen and the auxiliary separation screen are connected to the frame and are respectively located below the main threshing drum and the auxiliary threshing drum. The power device is arranged on the side of the frame to provide power for the main threshing drum and the auxiliary threshing drum. The threshing cover is connected to the frame and covers the main separation screen and the auxiliary separation screen. The receiving hopper is placed below the main separation screen and the auxiliary separation screen. By arranging the main threshing chamber and the auxiliary threshing chamber, the grain threshing device has a good threshing effect during use, and the threshing and separation load of each threshing chamber is light. The main threshing chamber is an open threshing chamber, which makes the threshing chamber easy to clean.

[0005] 2. A double-drum soybean seed thresher with publication number CN117941543A, which discloses a shell, a feed hopper, a threshing assembly and a cleaning screen; the threshing assembly and the cleaning screen are both installed inside the shell, and the cleaning screen is located below the threshing assembly; the cleaning screen is used to filter and clean the short threshing objects dropped from the threshing assembly; the threshing assembly separates the soybean seeds from the plants by beating the soybean plants; by arranging radial deformation sheets, after the soybean plants enter the threshing channel, the elastic lifting effect of the radial deformation sheets on the soybean plants is utilized, so that on the one hand, the soybean plants are in elastic contact with the threshing drum, and on the other hand, the soybean plants are more dispersed in space, the gaps between the soybean plants are increased, and the downward movement of the soybean seeds is facilitated, thereby reducing the probability of the soybean seeds being repeatedly beaten, resulting in a reduced breakage rate of the soybean seeds after threshing;

[0006] The above-mentioned existing technologies only have the function of grain separation. After the crops enter the grain separation equipment, they are rolled by the rollers so that the crops are transported in a straight line from the feed port to the discharge port. In this process, grain separation is performed. If too many crops enter the feed port and the rollers do not have the function of dispersing the feed conveying path, the crops will be concentrated at the feed port. When the processing capacity of the rollers and their supporting transmission systems is exceeded, the rotation of the rollers will be hindered, affecting the life of the equipment. At the same time, the crops are densely accumulated inside the equipment, so that each grain is subjected to insufficient impact and friction, resulting in incomplete grain separation and a high grain residue rate, which affects the grain separation efficiency. In view of this, an in-depth study is conducted on the above-mentioned problems, and a rice transverse axial flow double-drum grain separation device is designed. Summary of the invention

[0045] Embodiment: A rice transverse reciprocating conveying flow double drum processing device, comprising a feeding port 1 and a discharging port 2:

[0046] A frame 3 is installed between the feeding port 1 and the discharging port 2, a bottom shell 4 is installed between the inner wall surfaces of the frame 3, a top cover 5 is installed on the bottom shell 4, a pre-processing roller 6 and a post-processing roller 7 are installed on the frame 3 and between the bottom shell 4 and the top cover 5, the pre-processing roller 6 is close to the feeding port 1, and the post-processing roller 7 is close to the discharging port 2, and a driving component 8 is installed on both the pre-processing roller 6 and the post-processing roller 7;

[0047] Specifically, the driving assembly 8 drives the pre-processing drum 6 and the post-processing drum 7 to rotate counterclockwise, and the rice to be separated from the grain enters the grain separation chamber composed of the frame 3, the top cover 5 and the bottom shell 4 from the feeding port 1. The space where the pre-processing drum 6 is located is the front grain separation chamber, and the space where the post-processing drum 7 is located is the rear grain separation chamber. The rice stalks pass through the front grain separation chamber and the rear grain separation chamber successively, and are separated from the grains by the pre-processing drum 6 and the post-processing drum 7. The grains pass through the bottom shell 4 and fall to the bottom of the frame 3, and are discharged from the straw discharge port 2.
