Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a wild barley awn removing device. Background Art

[0002] Wild barley, a perennial herbaceous plant of the Poaceae family, is a native plant in the western region of the Songnen Plain. It has the excellent characteristics of salt-alkali resistance, drought resistance, and good palatability. It is both an excellent forage and a high-quality grass species for improving saline-alkali land. At present, domestic and foreign scholars' research on wild barley mainly focuses on endophytic fungi and their symbionts, grain shattering, salt tolerance, yield and nutritional quality, and there are fewer studies on wild barley seed cultivation. In the process of wild barley seed cultivation, in order to facilitate the recording of grain weight, per-acre yield and germination of wild barley seeds, after the wild barley seeds are harvested, it is necessary to use an awn removal device to remove thorns and hulls from the wild barley. For example, a barley awn removal device disclosed in the Chinese patent with the existing authorization announcement number CN213408786U belongs to the field of agricultural machinery technology and is used to solve the problems that the existing device cannot remove wheat awns of different particle sizes, the awn removal effect is poor, the awn removal efficiency is low, and the barley, thorns and hulls after awn removal cannot be separated. It includes a awn removing box and a pulley mechanism, a plurality of legs are fixed to the lower end of the awn removing box, a dust removal fan is fixed on the right leg, and a motor is fixed on the left leg. The output shaft of the motor is connected to the pulley mechanism. A first awn removing chamber and a second awn removing chamber are provided inside the awn removing box, and a first awn removing mechanism and a second awn removing mechanism are rotatably provided inside the first awn removing chamber and the second awn removing chamber respectively. A dust removal port is provided on the first awn removing chamber, and a first suction pipe is connected to the dust removal port. A collecting hopper is provided under the second awn removing chamber, a debris removal port is provided on the left side of the collecting hopper, and a second suction pipe is provided on the debris removal port.

[0003] However, in actual application, the above-mentioned device still has the following shortcomings: the above-mentioned device drives the first de-awning blade head to rotate by the first de-awning roller and drives the second de-awning blade head to rotate by the second de-awning roller, thereby separating seeds, thorns and husks. However, since the first de-awning blade head and the second de-awning blade head can easily cut and damage the seeds during the rotation process, the germination rate of the separated seeds is extremely low, making it difficult to cultivate and use them again, and the practicality is poor. Utility Model Content

[0004] The purpose of the utility model is to address the above-mentioned deficiencies and provide a wild barley awn removal device, which can effectively separate seeds, awns and husks, and effectively reduce the damage to seeds caused by cutting, thereby improving the germination rate of seeds after separation and having better practicality.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The sieve drum is rotated by the motor and the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum, the motor is driven by the sieve drum to move the sieve drum to the sieve drum

[0007] Furthermore, spiral blades are provided in the sieve cylinder, and the spiral blades divide the interior of the sieve cylinder into spiral channels.

[0008] Furthermore, the output shaft of the motor is driven and connected to a driving shaft, and a driving wheel 1 and a driving wheel 2 are provided on the driving shaft. The screen drum is rotatably connected to the cylinder body through bearing 1 and bearing 2; the transmission structure 1 includes a driven wheel provided on the cylinder body, which is used to connect the belt of the driving wheel 1 and the driven wheel.

[0009] Furthermore, the rotating ring is rotatably connected to the cylinder through bearing three; the transmission structure two includes an external gear arranged on the rotating ring, and an opening is provided on one side of the cylinder facing the external gear, and the driving wheel two extends into the cylinder from the opening and engages with the external gear.

[0010] Furthermore, a discharge port communicating with the cutting space is provided at the bottom of the cylinder.

[0011] Furthermore, the aperture of the sieve is larger than the radius of wild barley seeds.

[0012] The beneficial effects of the utility model are:

[0013] In actual application, the dried wild barley is put into the funnel, and the wild barley falls into the sieve drum through the funnel. When the motor drives the sieve drum to rotate through the transmission structure 1, the burrs of the wild barley gradually extend from the sieve holes. The motor drives the rotating ring through the transmission structure 2 to drive the cutting blade to cut along the outer wall of the sieve drum, and the burrs extending out of the sieve holes are cut off. When the wild barley slides downward along the sieve drum, the wild barley seeds are separated from the husks until the wild barley seeds and the husks fall out from the lowest end of the sieve drum. Since the weight of the seeds is greater than the husks, the husks are blown to the trough body 2 by the separation fan, and the seeds fall into the trough body 1 under the action of gravity. The utility model can not only effectively separate seeds, burrs and husks, but also effectively reduce the damage of seeds being chopped, thereby improving the germination rate of seeds after separation, and has better practicality.

[0019] During use, the dried wild barley seeds are put into the funnel 7, and the wild barley falls into the sieve drum 3 through the funnel 7. During the rotation of the sieve drum 3 driven by the motor 6 through the transmission structure 1, the burrs of the wild barley gradually extend from the sieve holes 31, and the motor 6 drives the rotating ring 4 through the transmission structure 2 to drive the cutting blade 5 to cut along the outer wall of the sieve drum 3, and the burrs extending out of the sieve holes 31 are cut. During the sliding of the wild barley downward along the sieve drum 3, the wild barley seeds are separated from the husks until the wild barley seeds and the husks fall out from the lowest end of the sieve drum 3. Since the weight of the seeds is greater than the husks, the husks are blown to the trough body 2 82 by the separation fan 9, and the seeds fall into the trough body 1 81 under the action of gravity. The utility model can not only effectively separate seeds, burrs and husks, but also effectively reduce the damage of seeds being chopped, thereby improving the germination rate of seeds after separation, and having better practicality.
