Embodiment 1

[0037] Embodiment 1 discloses a kind of paddy screening separator suitable for different paddy after shelling, refer to the attached figure 1 And attached figure 2 Its main body includes a screening box 1 and a dust collecting bucket 2. The dust collecting bucket 2 is connected with the lower surface of the screening box 1, and is used to collect and sieve the falling dust and impurities. A leg 3 is connected to each place, and a control panel 100 for controlling the whole paddy screening and separating machine is arranged on the screening cabinet 1 .

[0038] Reference attached image 3 And attached Figure 4 , a horizontally arranged screen cylinder 4 is arranged inside the screening cabinet 1, and a large number of screen holes are opened on the cylinder body of the screen cylinder 4, and ring bodies 401 are connected to both ends of the screen cylinder 4. At the same time, the left and right ends of the inner cavity of the screening cabinet 1 are respectively fixedly c...

Embodiment 2

[0045] Embodiment 2 discloses a paddy screening separator with anti-clogging function improved on the basis of Embodiment 1. Its similarities with Embodiment 1 will not be described again in Embodiment 2. The difference is that:

[0046] Reference attached figure 1 And attached Figure 6 , this embodiment 2 is also provided with a compressed air pipe 15 parallel to the screen cylinder 4 directly above the screening cabinet 1, and one end of the compressed air pipe 15 is connected to a compressed air source (not shown in the figure), and compressed A master valve is arranged at the connection between the air pipe 15 and the compressed air source. At the same time, the lower surface of the compressed air pipe 15 is connected with a plurality of compressed exhaust branch pipes 16 at equal intervals, and the lower end of each compressed exhaust branch pipe 16 stretches into the inside of the screening cabinet 1 and is arranged against the screen cylinder 4, and each A solenoid v...

Embodiment 3

[0051] Embodiment 3 discloses an improved paddy screening separator based on Embodiment 2, which mainly aims at the deficiency that Embodiment 2 cannot effectively dredge the screen holes between two adjacent compression exhaust branch pipes 16, and its The same as embodiment 2 will not be described again, the difference is:

[0052] Reference attached figure 1 , attached figure 2 And attached Figure 6 , the present embodiment 3 is also provided with a bar-shaped mouth 101 corresponding to each compression exhaust branch pipe 16 on the upper surface of the screening cabinet 1, and each compression exhaust branch pipe 16 is stretched into the screen through the bar-shaped mouth 101 The cabinet 1 is arranged facing the screen drum 4 .

[0053] Simultaneously, the compressed air pipe 15 among the present embodiment 2 is divided into three sections and is arranged, and the first section is the air intake hard pipe 151 that is connected with the compressed air source, and the ...

Abstract

The invention relates to the technical field of rice processing equipment, and particularly discloses a paddy rice screening separator. The paddy rice screening separator comprises a machine box, a dust collecting hopper and a screening drum, a feeding end sleeve and a discharging end sleeve are fixedly arranged at the two ends in the machine box respectively, the screening drum is rotationally connected between the feeding end sleeve and the discharging end sleeve, a first driving device used for driving the screening drum to rotate is arranged on the machine box, and spiral blades are arranged in the screening drum; a second driving device used for driving the spiral blades to rotate is arranged on the machine box, a compressed air pipe connected with a compressed air source is arranged above the machine box, the compressed air pipe and the screening drum are arranged in parallel, and a plurality of compressed exhaust branch pipes which extend into the machine box and directly face the screening drum are connected to the compressed air pipe at equal intervals. An electromagnetic valve is arranged on each compression exhaust branch pipe. The paddy rice screening separator not only has an excellent anti-blocking effect, but also can be suitable for paddy rice separation of different types of rice, and is excellent in use effect and wider in application range.

Description

technical field [0001] The invention relates to the technical field of rice processing equipment, and specifically discloses a paddy screening and separating machine. Background technique [0002] Paddy-grain separation is a major procedure in rice processing. The quality of paddy-grain separation plays an important role in reducing consumption, increasing rice yield and ensuring the quality of finished products. The dust and other impurities in the material are easy to adhere to the sieve surface when the rice and rough separators on the market are separating the rice and rice. After a long time of use, the screen holes on the screen surface will be blocked, which will affect the normal use of the rice and rice separator. This makes the effect of subsequent paddy separation and screening poor. [0003] For example, the invention with application number CN2019113906820 discloses a high-efficiency paddy separator, including a frame; a first screening mechanism, including a f...
