Description

Novel grain combination clearance device

Technical Field

The utility model relates to a novel grain combined cleaning device, and belongs to the field of grain processing equipment.

Background

After harvesting rice and other grains, a large amount of sundries such as weeds, straw, rope ends, bricks, stones, glass fragments and the like are mixed, and before the grains are put in storage, the sundries in the grains must be sorted and cleaned.

The mixed impurities in the grains are classified into light impurities (such as rice husk, dust, crushed straw, etc.) and heavy impurities (such as sand, crushed stone, etc.) according to the mass of the mixed impurities, and are classified into large impurities and small impurities according to the volume of the mixed impurities. The existing grain machinery cleaning equipment has single functions, such as winnowing, gravity screening and the like, and different equipment has different performances and characteristics and defects.

The Chinese patent with the application number of CN201720401152.1 provides a grain multi-stage sorting combined cleaning sieve; when the grain screening device works, the grains need to fly up to be subjected to dust collection and screening, so that the dust in the machine is very large. When cereal is screened on the screening surface of the screen box, the screen holes are also often blocked due to the fact that some impurities are retained on the screening surface, so that the phenomenon that the cereal is unsmooth when passing through the screen holes occurs, and screening efficiency is reduced.

The combined cleaning sieve adopts a gravity flow type winnowing grain cleaner with the application number of CN201620063661.3, grains flow from top to bottom automatically without active power supply, and the grains are fully thrown upwards under the action of the J-shaped bending plate, so that light impurities and dust are effectively removed, and the problem that the sieve holes are blocked due to the fact that the impurities are retained on the sieve surface can be solved;

however, the grains are various, the weight and the grain size of each grain are different, and the rebound paths generated by falling on the J-shaped bending plate with a fixed shape are different; if the grain is the rice that the granule is less, then strike and rebound the dynamics is less on J shape bending plate, if the grain is the great soybean of granule, then strike and rebound the dynamics is great on J shape bending plate, probably strike on blade or box, the striking makes a round trip like this can cause the damage of grain.

Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

Referring to figures 1-6, which illustrate an embodiment of a novel grain combination cleaning apparatus according to the present utility model,

Comprises a box body 1 and a plurality of bending plates 2 arranged in the box body 1; wherein, the bending plate 2 comprises a mounting plate 21 and an adjusting plate 22, and the adjusting plate 22 is rotatably arranged on the mounting plate 21; the case 1 is provided with vent holes 3, and the vent holes 3 are arranged between the bending plates 2.

The device is used for cleaning equipment of grains, the cleaning equipment is combined equipment, and meanwhile, the device is a feeding component of the combined equipment;

the feeding component of the device is formed by combining a box body 1, a filter screen, a fan cover and an exhaust fan; and improves the structure inside the box body 1; the concrete improvement structure is: the device improves the structure of the bending plate 2 on the basis of the prior art, the bending plate 2 consists of a mounting plate 21 and an adjusting plate 22, and the adjusting plate 22 is rotatably arranged on the mounting plate 21;

When grain particles are input into the box body 1 which is obliquely arranged, the grain can impact on the mounting plate 21 or the adjusting plate 22 of the bending plate 2 due to the action of gravity, and then the impact force is reacted on the grain particles, so that the grain particles rebound; the device can operate the adjusting plate 22 to control the inclination angle of the adjusting plate 22, help grain particles to control the rebound angle when rebounding, prevent the grain particles from rebounding to the inner wall of the other side of the box body 1, and protect the grain particles from being broken due to excessive impact.

In order to facilitate the operation of the adjusting plate 22 by the staff, the device is provided with the following structure:

The adjusting plate 22 is rotatably connected with the mounting plate 21 through a rotating shaft 4; one end of the rotating shaft 4 is provided with a gear 5, and the gear 5 is provided with a toothed chain 6; and a rocker 7 is connected to one of the gears 5.

The gears 5 are meshed and connected through the toothed chain 6, when the toothed chain 6 drives, the gears 5 rotate synchronously, at the moment, each gear 5 controls the rotation of the rotating shaft 4 connected with the gears 5, and the rotating shaft 4 drives the adjusting plate 22 to adjust the inclination angle; the adjustment of the toothed chain 6 is driven by means of the rocker 7 on one of the gears 5, and when the rocker 7 is rotated by a worker, the rocker 7 drives one of the gears 5 to rotate, and the toothed chain 6 is driven by the gear 5.

The end of the adjusting plate 22, which is far away from the rotating shaft 4, is also provided with a striker plate 23.

The device is provided with the baffle plate 23 by comprehensively considering the weight of grain particles, the path of grain particles after rebound caused by the inclination angle of the adjusting plate 22 and the influence of the wind power of the exhaust fan on the grain particles;

When the grain particles are lighter in weight, the rebound force is insufficient, the influence of wind power of the exhaust fan is larger, and then the grain particles can possibly enter the ventilation hole 3 and are pumped away by the exhaust fan; however, if the wind power of the exhaust fan is reduced, the grains such as dirt, dust and the like carried by the grains cannot be effectively removed; the provision of the wind deflector prevents grain particles from being sucked into the ventilation hole 3 under the condition of the suction fan opening the horsepower.

The dam plate 23 is provided with a ventilation groove 24 therein.

The ventilation groove 24 is a further improvement on the baffle plate 23, so that the power of the exhaust fan can be reduced, the area through which air flows is increased, and the effect of cleaning grain particles when the exhaust fan is in full horsepower is achieved; but the inclination angle of the adjustment plate 22 needs to be changed; experiments are specifically required to be carried out according to grain types, and after the experiments of the device are carried out, a conclusion suitable for wheat is obtained.

The ventilation grooves 24 are vertical grooves and are uniformly arranged on the striker plate 23.

The arrangement is convenient to process, reduces the cost, but gathers grain particles;

The ventilation grooves 24 are circular grooves and are arrayed on the striker plate 23.

The device has high processing cost and has the function of dispersing grain particles, but dust is easy to adhere to the circular groove and needs to be cleaned at regular time.

The vent hole 3 is a strip-shaped through groove, and a filter screen is arranged on the vent hole 3; the box 1 is provided with the fan housing that covers on ventilation hole 3 outward, and fan housing one end is provided with the air exhauster.

So set up, make things convenient for the convulsions, can play filterable effect simultaneously.
