Abstract

A spring type particle sieving device is characterized by consisting of an upright column, a spring, a bolt, spring gaskets, a sieve and baffles, wherein the upright column is connected with the sieve through the bolt; the spring sleeves the bolt; the spring gaskets are arranged at two ends of the spring; the baffles are arranged on the periphery of the sieve; and the spring is arranged under the sieve. When particles are fed in the spring type particle sieving device, the spring is extruded, the whole sieve moves downwards, the number of the particles is reduced while the sieve moves, after the number of the particles is reduced to a certain degree, the sieve is pushed upwards by using elasticity of the spring, the small number of particles are popped up by the sieve, the popped-up particles drop downwards owing to the gravity of the particles and then are in contact with the sieve, the spring is extruded again and moves downward, so that large particles are filtered out by reciprocating motion of the spring, manual particle sieving operation is reduced, and the work efficiency is improved.

Description

Spring particle screen selecting device

Technical field

The utility model belongs to modern agriculture field, especially a kind of spring particle screen selecting device.

Background technology

The development of mechanization of agriculture is used to greatest extent various machinery to replace hand tools to produce in agriculture all departments.As in plant husbandry, use tractor, seeder, harvester, power irrigation and drainage machine, motor vehicles etc. to carry out every operations such as ploughing soil, sowing, harvesting, irrigation, field management, transport, make whole production processes mainly rely on machine power and electric power, instead of rely on manpower, animal power to complete.The crops such as rice and wheat are shaped as particle, this description by rice and wheat etc. referred to as particle.Realize the mechanization of farm work, can save labour, reduce labor intensity, improve farm labor efficiency, but in the process of agricultural mechanization development, for example the farm equipment of rice, wheat harvester is mature on the whole, but when with these equipment by rice and little wheat harvesting complete after the inside with a lot of foreign material (stalks, also can be called bulky grain thing) need cleaning, be all the artificial wind-force by fan in the past, rice and wheat are thrown, stalk dubs relatively, the gravity being subject to is little, and it is far away that fan blows, and profit allows it separately in this way.Also some remoter rural area also rests on now and picks bulky grain thing with hand in addition.These two kinds of method efficiency are lower.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of spring particle screen selecting device of simple in structure, economy and durability is provided.

The technical scheme that the utility model is taked is:

A kind of spring particle screen selecting device, it is characterized in that, formed by column (1), spring (2), bolt (3), spring shim (4), sieve (5) and baffle plate (6), column (1) is connected with sieve (5) by bolt (3), the upper cover of bolt (3) has spring (2), spring (2) two ends are provided with spring shim (4), and sieve (5) surrounding is provided with baffle plate (6).

Spring shim (4) is matched in clearance with bolt (3), ensures that spring (2) does not contact with sieve (5) with column (1).

Baffle plate (6) surrounding is equipped with four root posts (1).

Spring is installed below sieve, and in the time having particle, spring is squeezed, entirety sieve moves downward, and in sieve motion, particle is reducing, and particle reduces to a certain degree, the elastic force of spring upwards pushes away sieve, sieve is upspring a small amount of particle, and the particle of upspringing contacts with sieve by gravity landing downwards again, and spring is squeezed and moves downward again, move back and forth like this, filter out bulky grain thing, reduced people screens particle work with hand, improved operating efficiency.
