Quick rapeseed sorting device

Technical Field

The utility model relates to a round seed sorting device, in particular to a rapid rapeseed sorting device; belongs to agricultural machinery.

Background

Rapeseed is a raw material for pressing rapeseed oil, and solid impurities such as broken soil, broken leaves and broken rods are mixed in the rapeseed harvesting process, so that the rapeseed is generally rinsed and dried before oil pressing. Because the grains of the rapeseeds are different in size, uneven heating is easily caused in the drying process. Rapeseeds with large particles are heated less, the temperature is lower, and the drying is slower; rapeseeds with small particles are heated more and are heated at higher temperature, so that grease is easy to overflow to form adhesion. In order to ensure the drying quality, the rapeseeds are preferably cleaned and graded by adopting a multi-stage vibration screening device before rinsing.

For this reason, CN209791978U discloses a vibrating screening device for rapeseed, which comprises a fine screen, a middle screen, a coarse screen, and cams located on the back of the screens. The device can realize multi-stage vibration screening of rapeseeds, and has a simpler structure; but has the following disadvantages:

1) the motion path of the rapeseeds is zigzag, so that the sorting time is long and the efficiency is low.

2) The movement of rapeseeds is long, so that the whole machine is not compact enough and has large volume.

3) The mesh size of each grade of screen mesh is fixed, and the rapeseeds with three grain sizes can only be screened, but the rapeseeds with various grain sizes can not be selected steplessly according to the requirement.

4) Because the meshes of the screen are easy to block, the screen needs to be cleaned and dredged frequently.

As shown in FIGS. 1-12: the frame consists of a drum-shaped casing 3 fixed to a base 7, the inner wall of which is welded four support plates 14 and a support ring 12.

The transmission part comprises a shaft sleeve 20, four connecting plates 21 welded on the surface of the shaft sleeve, a main shaft 19 supported in the shaft sleeve 20 through a bearing (not shown), a material blocking disc 22 which is fixed at the right end of the main shaft and has a bamboo hat-shaped structure and a brim 27, and a main motor 10 which is fixed on the base 7 and drives the main shaft 19 to rotate through a belt transmission device, wherein the belt transmission device comprises a small belt pulley 9 fixed on the main motor 10, a large belt pulley 11 fixed at the left end of the main shaft 19, and a belt 8 connecting the large belt pulley and the small belt pulley 9. The right end of the sleeve 20 is supported on the support ring 12, and the left end of the sleeve is fixedly connected with the corresponding support plate 14 through four connecting plates 21.

The screening part is composed of a screen drum 17 which is positioned in the shell 3 and is in a circular truncated cone shape and a flange 29 which is fixed on the small end surface of the screen drum, and the inner surface of the screen drum 17 is provided with a plurality of screen gaps 28 which are in a wedge-shaped strip structure and are distributed along the bus direction; the left end of the screen cylinder 17 is fixedly connected with the brim 27 of the material blocking disk 22 through a flange 29, and the right end of the screen cylinder 17 is in a cantilever state.

The oscillating portion is formed by a bearing housing 25 welded to the sleeve 20, two eccentric masses 15 supported on the bearing housing by a rotating shaft (not shown), and an oscillating motor 16 fixed in the casing 3 and fixedly connected to one of the eccentric masses 15 by a coupling 26.

The feeding part is composed of a hopper 1 fixed on the top of the machine shell 3, a material control gate plate (not shown in the figure) arranged below the hopper, and a feeding pipe 24 with the upper end communicated with the hopper and the lower end extending into the screen drum 17.

The discharge part is composed of a plurality of discharge chutes 4 (only two are shown in the figure) which are arranged below the screen drum 17 and arranged along the length direction of the screen slot 28, and a tail chute 5 which is positioned below the large end surface of the screen drum 17.

The air separation part is composed of a fan 2 which is positioned below the material control gate plate and fixed on the side surface of the hopper 1 and a slag discharge pipe 13 which is positioned on the opposite side of the fan and fixed on the hopper 1.

In order to ensure smooth feeding and avoid material accumulation, a material distribution device is also arranged in the screen drum 17. The material distributing device is composed of a trumpet-shaped or splayed material distributing cover (not marked in the figure) welded at the lower end opening of the feeding pipe 24 and a conical material homogenizing cap 23 fixed on the surface of the material blocking plate 22 through screws, wherein the material homogenizing cap extends into the material distributing cover and is spaced from the inner surface of the material distributing cover by a certain distance.

In order to prevent the screen slot 28 from being clogged, the cross-sectional shape of the back surface of the screen slot 28 in the width direction is formed in a trumpet-like or "figure-eight" shape.

In order to reduce the vibration of the whole machine, the machine shell 3 and the base 7 are fixedly connected through a first damping spring 6 respectively; in order to reduce the vibration of the housing 3, each support plate 14 is fixedly connected to the corresponding connecting plate 21 by a second damping spring 18.

In order to maintain balance, the vibrating portion has two sets of structures symmetrically distributed about the center line of the sleeve 20.

The working principle is as follows: under the action of vibration, when the materials in the hopper 1 continuously fall to the position of the air separation part, light impurities such as crushed leaves, crushed rods, empty and shriveled grains and the like mixed in the materials can be discharged through the slag discharge pipe 13; the remaining material enters the distribution device through the feeding pipe 24. Under the blocking and dispersing action of the material homogenizing cap 23, the material is uniformly scattered in the screen drum 17 along the gap between the material homogenizing cap 23 and the material distributing cover. The main motor 10 drives the screen drum 17 to rotate through the belt transmission device, the main shaft 19 and the material blocking disc 22 in sequence. Under the combined action of vibration, rolling and gravity, the materials in the screen drum 17 firstly fall from the screen slit area with narrow width and enter the small-particle-diameter collecting discharge chute 4, the materials with large particle diameter slide down to the screen slit area with large width along the taper of the screen drum 17 and fall into the large-particle-diameter collecting discharge chute 4, and the residues with larger size continue to slide down and fall into the tail chute 5 from the large port of the screen drum 17.
