Problems solved by technology

[0003] Usually, the size, weight, and particle size of the sundries are different from those of agricultural seeds. Therefore, in the actual production process, there are air selection methods based on different weights, mesh screening methods based on particle sizes, and water filters based on different floatability. Selection method, each method has its own advantages and disadvantages, and the screening effect and efficiency are different. Therefore, a combined agricultural seed screening device can be invented to improve the screening effect and efficiency.

Embodiment 1

[0022] Such as figure 1 As shown, the crop seed screening equipment for two-step screening described in this embodiment includes a small particle screening device 1 and a water separation device 2, and the small particle screening device 1 is located at the upper left of the water separation device 2, and is characterized in that:

[0023] Such as figure 2 , the small particle screening device 1 includes a casing 101, the top left side of the casing 101 is provided with a feed hopper 102, the bottom of the casing 101 is provided with a collection bin 103, and the collection bin 103 is provided with an outlet window 116 with a filter screen , the wind can be blown out from the air outlet window 116 and other sundries cannot pass through; Rotatable screen pipe 105, the angle of inclination of screen pipe 105 can be selected between 20-50 degrees, here is 45 degrees, the outlet of feed hopper 102 is inserted into screen pipe 105 and can be relatively rotated between the two, sc...

Embodiment 2

[0029] Such as Figure 4 Shown, the crop seed screening equipment of two-step method screening described in this embodiment, on the basis of embodiment 1, also has the following characteristics:

[0030]The lower left part of the water chamber 201 is provided with an internal circulation pipe 209. The nozzle on the top of the internal circulation pipe 209 is located above the inverted splayed guide plate 208, and the lower nozzle is located below the inverted splayed guide plate 208. On the internal circulation pipe 209, there are The forward pump 214 and valve that are driven downwards are also provided with a bypass 210 on the internal circulation pipe 209, and the reverse pump 215 and valves that are driven from top to bottom are provided on the bypass 210. The forward pump 214 pumps from bottom to top, and the reverse pump 215 pumps from top to bottom. When the forward pump 214 works, the reverse pump 215 does not work, and the valve corresponding to the pump that does not...

Abstract

The invention discloses crop seed screening equipment realizing two-step screening. The crop seed screening equipment comprises a small particle screening device and a water screening device; the small particle screening device comprises a housing; a feed hopper is arranged at the top of the left side of the housing; a collecting bin is arranged at the lower part of the housing; the collecting binis provided with an air discharging window provided with a filter screen; the lower part of the right side of the housing is provided with a discharging pipe; a pipe seat is arranged at the internalupper left part of the housing; an inclined rotatable screening pipe is arranged inside the housing; the water screening device comprises a water chamber; the left side of the top of the water chamberis provided with an inlet pipeline; the downward-bent opening of the discharging pipe of the small particle screening device faces to the inlet pipeline; the upper right part of the outer side of thewater chamber is provided with an overflowing chamber; and the water chamber communicates with the overflowing chamber via an overflowing opening. The crop seed screening equipment disclosed by the invention realizes better guarantee on the screening effect by adopting a combination way of two-step screening including screen type screening of the screening pipe and water screening; the two typesof equipment are sequentially arranged up and down; and the steps are implemented sequentially; so the crop seed screening equipment is high in work efficiency, more beneficial for the screening workof large-batch agricultural seeds and high in practicability.

Description

technical field [0001] The invention relates to an agricultural equipment, in particular to a two-step screening equipment for crop seeds. Background technique [0002] Since the agricultural seeds are easy to be mixed with empty grains, shriveled grains (small particles of unfulfilled seeds), dust, seed shells, straw shells, weeds and other sundries during the collection process, these sundries need to be screened out, and the normal agricultural seeds reserve. [0003] Usually, the size, weight, and particle size of the sundries are different from those of agricultural seeds. Therefore, in the actual production process, there are air selection methods based on different weights, mesh screening methods based on particle sizes, and water filters based on different floatability. Selection method, each method has its own advantages and disadvantages, and the screening effect and efficiency are different. Therefore, a combined agricultural seed screening device can be invented...
