Description

Technical Field

[0001] The invention relates to a grain drying device, in particular to a grain drying and awn-removing integrated machine. Background Art

[0002] At present, grain harvesting has basically been mechanized. Because grains have whiskers and husks. And the surface of the awns has single-cell epidermal hairs, which contain rich silicon and have the habit of sticking. Grain combine harvesters cannot remove them completely, so the awns are mixed with the grains. When they are sent to the grain dryer for drying, they accumulate in the gap between the grain outlet trays. Over time, the grain outlet of the dryer is blocked, and the whole dryer cannot work.

[0003] During the harvesting process of grains by existing harvesters, awn whiskers and husks are mixed in the grains along with the sieve holes. The awn whiskers are deposited in the grain-supporting groove of the grain-shifting wheel, and over time, they become blocked and block the grain-shifting wheel, making it difficult to discharge grain, until the grain-shifting wheel cannot be turned and cannot be discharged.

[0004] Therefore, how to provide a grain dryer that can effectively remove awns and avoid clogging of the grain wheel is a problem that those skilled in the art urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides a grain drying and awn removing integrated machine, which can remove the thorns of grains and dry the grains.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a grain drying and awning-removing integrated machine, which comprises a machine body, a circulation lifting device and an awning-removing device, a slow-release layer and a drying layer are arranged inside the machine body, the slow-release layer is arranged close to the top of the machine body, and the drying layer is located below the slow-release layer, a guide plate is obliquely arranged inside the machine body and below the drying layer, the bottom of the guide plate is bent to form a grain-supporting groove, and the material passes through the slow-release layer and the drying layer and slides along the guide plate to be collected in the grain-supporting groove, a grain-dispensing wheel is rotatably connected to the machine body and is located above the grain-supporting groove; a conveying device is horizontally arranged below the machine body corresponding to the grain-supporting groove, the circulation lifting device is vertically fixedly connected to one side outside the machine body, and its bottom is fixedly connected to the conveying end of the conveying device, a feeding port is arranged at the bottom of the circulation lifting device, and a discharge pipe is fixedly connected to the top edge of the circulation lifting device, and the bottom of the discharge pipe is connected to the top of the machine body;

The materials are lifted by the circulation lifting device, lifted to the top through the bucket and enter the discharge pipe. Since the bottom of the discharge pipe is connected with the top of the machine body, the materials fall onto the awn baffle plate, which is connected to the layer screen. The layer screen moves back and forth under the drive of the servo connection mechanism. Since the masses of grains and thorns are different, the materials enter the layer screen under the action of the awn baffle plate. The layer screen can screen the grains and thorns. The thorns gather on the surface of the grains. The fan blades in the exhaust cylinder draw away the thorns under the action of the exhaust motor. The grains fall to the slow drying layer and the drying layer through the layer screen, and gather to the grain supporting groove at the bottom of the guide plate through the guide plate. Under the grain shifting action of the grain shifting wheel, the grains enter the conveying device. At this time, part of the grains can be separated from the thorns due to the abutment between the grain shifting wheel and the grains. The conveying end of the conveying device is fixedly connected to the circulation lifting device to further lift the materials, and work in a reciprocating cycle until the thorns are peeled off and extracted cleanly.

[0029] Specifically, the awn baffle 301 is tilted and fixed at one end of the layer screen 302, and the grains in the discharge pipe 10 slide onto the layer screen 302 through the awn baffle 301. The function of the awn baffle is that the material hits the awn baffle, and the reciprocating motion of the servo connection mechanism is used to separate the material from the awns.

[0032] Specifically, surrounding panels are provided on the four side walls of the machine body 1.

[0033] More specifically, the conveying device 16 is a conveying auger, which is rotatably connected to the inner bottom of the machine body. The function of the conveying auger is to collect the materials flowing down the grain supporting groove and convey them to a circulation device at one end, and then send them to the top of the machine body again under the action of the bucket and the circulating belt for de-awning and drying.

[0034] In some other embodiments, such as Figure 6 As shown, the speed regulating motor is fixedly mounted at one end of the hanger, a vertical rod is vertically fixed on the guard plate at one end of the layer screen away from the awn baffle, the eccentric wheel 3042 is drivingly connected to the output shaft of the speed regulating motor 303, one end of the connecting rod 3041 is hinged to the top of the vertical rod, and the other end is drivingly connected to the eccentric wheel 3042 through the eccentric shaft, so that the servo connection mechanism drives the layer screen to move back and forth.

[0035] The working principle of the present invention is as follows: the grains to be dried mixed with awn husks are poured into the lower bin at the feed inlet, and the grains are lifted to the top of the dryer by the bucket on the circulating belt in the circulating lifting device, and discharged downward through the discharge pipe. When the grains fall to the awn blocking board, the awn husks and grains are intercepted. The quality of awn is lighter than that of grains or cereal grains. The layer screen movably connected with the awn blocking plate drives the awn blocking plate to reciprocate. The awn slides to the layer screen to generate centripetal force. Under the action of the centripetal force, the lightweight awn shells are thrown to the upper layer and gathered at the center point of the layer screen. An exhaust pipe is arranged above the center point to discharge the awn shells, and the cereal grains on the awn blocking plate enter the layer screen, continuously fall into the slow-heating layer from the holes, and go down to the drying layer for drying. When there is awn shell that has not been discharged, it continues to be mixed with the cereal grains and moves to the grain supporting groove. With the rotation of the grain shifting wheel, part of the awn shells are separated from the cereal grains during the grain shifting process, and fall into the horizontal conveying device 16 at the bottom of the warehouse, and are transported to the circulating lifting device, and then lifted again - release the grain - block the awn - discharge the awn - go down - fall into the warehouse, and the cycle is repeated to remove the awn shells. It completely eliminates the problem of grain outlet being blocked by awn husks, eliminates the trouble of cleaning due to blockage, reduces labor intensity, saves human resources, reduces energy consumption due to heat absorbed by awn husks, reduces drying costs, improves grain drying quality, not only meets the drying needs of conventional grains, but also further meets the requirements of seed drying standards.

[0036] As for the device and the method of use disclosed in the embodiment, since they correspond to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
