[0002] The awn remover is mainly used to remove the awns from crops such as rice and sorghum to ensure their suitability for storage and transportation. During operation, the rotor assembly rotates inside the screen cylinder, causing the rice grains to tumble and rub against each other, thus breaking and removing the awns.
[0003] In the prior art, due to defects in the hammer structure of the rotor assembly, the surface of crops such as rice grains is often damaged when it rotates. Utility Model Content
[0004] The purpose of this invention is to address the deficiencies in the aforementioned technologies by providing a rotor assembly, a awn remover, and an awn removal system, which aims to prevent damage to the outer skin of crops such as rice grains during the operation of the awn remover.

The hammer body includes a hammer base and a hammer head, the hammer base being fixedly connected to the drive shaft, and the hammer head being rotatably connected to the hammer base.
[0007] In the above scheme, the hammer head and the hammer base are rotatably connected. When there is a large amount of crops in the sieve cylinder of the awning machine, the hammer head can be tilted at a certain angle relative to the hammer base, so that the space between the hammer head and the inner wall of the sieve cylinder is increased, preventing excessive compression between the hammer head and the inner wall of the sieve cylinder from damaging the skin of the crops.

[0028] This application provides a rotor assembly, a awn remover, and an awn removal system. The hammer head is rotatably connected to the hammer base. When there is a large amount of crop in the awn remover's sieve cylinder, the hammer head can be tilted at a certain angle relative to the hammer base, increasing the space between the hammer head and the inner wall of the sieve cylinder. This prevents excessive compression between the hammer head and the inner wall of the sieve cylinder, which could damage the crop's skin. This solves the problem of frequent crop skin damage during the awn removal process in the prior art.
[0029] To facilitate understanding of the technical solution of this application, its application scenarios are described below:
[0030] awn removers are commonly used to remove awns from crops such as wheat, rice, and beans. For example, removing awns from rice facilitates subsequent hulling, storage, and processing. They can also be used to remove awns, fuzz, or impurities from the surface of seeds, improving seed purity and sowing efficiency.
[0031] The following description, in conjunction with the accompanying drawings, further illustrates this implementation case:
[0032] Depend on Figure 1 — Figure 4 As can be seen, this application provides a rotor assembly 10 for use in a awn remover 100. The rotor assembly 10 includes a drive shaft 1 and a hammer body 2 connected to the drive shaft 1. The drive shaft 1 is used to connect to a drive mechanism 20, which drives the drive shaft 1 to rotate, thereby causing the hammer body 2 to rotate. The rotation of the hammer body 2 beats the crops inside the awn remover 100, causing the awns to fall off.
[0033] In some examples, the drive shaft 1 and the hammer body 2 are fixedly connected, such as by welding.
[0034] In some examples, the drive shaft 1 and the hammer body 2 can be detachably connected, such as by bolts or other connecting parts.
[0035] To prevent damage to the outer shell of crops during the rotation of the hammer body 2, which could affect seed germination rates, the hammer body 2 in this embodiment includes a hammer base 21 and a hammer head 22. The hammer base 21 is fixedly connected to the drive shaft 1, and the hammer head 22 is rotatably connected to the hammer base 21.
[0036] In some examples, the hammer base 21 is connected to the drive shaft 1 by welding.
[0037] In some examples, the hammer head 22 and the hammer base 21 are rotatably connected by a pin. Specifically, the hammer base 21 and the hammer head 22 are each provided with a connecting hole, and the pin is placed in the connecting hole to rotatably connect them.
[0038] In some examples, the hammerhead 22 may be in the shape of a sheet, a cylinder, etc., but this embodiment does not specifically limit it.
[0039] In the above scheme, the hammer head 22 of the hammer body 2 is rotatably connected to the hammer base 21. When there is a large amount of crops in the sieve cylinder 37 of the threshing machine 100, the hammer head 22 can be tilted at a certain angle relative to the hammer base 21, so that the space between the hammer head 22 and the inner wall of the sieve cylinder 37 is increased, preventing excessive compression between the hammer head 22 and the inner wall of the sieve cylinder 37 from damaging the skin of the crops.
[0040] In some possible implementations, see [reference] Figure 1 Multiple hammers 2 are arranged at intervals along the axial direction of the drive shaft 1. The multiple hammers 2, which are axially connected by the drive shaft 1, simultaneously pound the crops inside the threshing machine 100, thereby improving work efficiency.
[0041] In some examples, to improve the working efficiency of the rotor, multiple hammers 2 are provided on the drive shaft 1. Furthermore, the multiple hammers 2 are axially connected to the drive shaft 1. A certain interval is provided between adjacent hammers 2, which can be 10 cm, 15 cm, 20 cm, etc. This embodiment does not specifically limit the interval distance.
[0042] In some possible implementations, see [reference] Figure 1 The hammer body 2 has a hammer base 21 with multiple supports 211 along its radial circumference, and each support 211 is rotatably connected to a hammer head 22. In this way, the hammer base 21 is rotatably connected to the hammer head 22 through the supports 211, which facilitates assembly operations.
[0043] In some examples, the number of brackets 211 can be 2, 3, 4, 5, 6, etc., which can be set according to the specific capacity of the 100-ton auger.
[0044] In some possible implementations, see [reference] Figure 1 The bracket 211 is provided with a first connecting hole 211c, and the hammer head 22 is provided with a plurality of second connecting holes 221 along its length. The first connecting hole 211c on the bracket 211 is hinged to one of the second connecting holes 221 on the hammer head 22.
[0045] In some examples, the hammer head 22 has two second connecting holes 221 along its length, and the first connecting hole 211c can be connected to either of the second connecting holes 221. In this way, the length of the hammer head 22 can be adjusted by selecting to connect to different second connecting holes 221.
[0046] In some examples, the hammer 22 is provided with three or four second connecting holes 221 along its length to increase the adjustable range of the hammer 22 length.
[0047] In some possible implementations, see [reference] Figure 1The bracket 211 includes a first plate 211a and a second plate 211b, a first connecting hole 211c passing through the first plate 211a and the second plate 211b, and a hammer head 22 being clamped between the first plate 211a and the second plate 211b.
[0048] In some examples, the support 211 is composed of two plates, specifically a first plate 211a and a second plate 211b. The first plate 211a and the second plate 211b can be connected to the drive shaft 1 by welding or by bolts or other components. After the first plate 211a and the second plate 211b are connected to the drive shaft 1, a certain gap is provided between them to accommodate the hammer head 22, so that the hammer head 22 is clamped between the first plate 211a and the second plate 211b. In this way, when the hammer head 22 rotates, both sides provide support, improving the stability of the hammer head 22's rotation.
[0049] In some possible implementations, see [reference] Figure 1 The hammerhead 22 includes a third plate 222 and a fourth plate 223. The third plate 222 and the fourth plate 223 are rotatable relative to each other.
[0050] In some specific examples, the hammerhead 22 is made of a plate. Specifically, it includes a third plate 222 and a fourth plate 223. Both the third plate 222 and the fourth plate 223 are rotatably connected to the bracket 211 by pins.
[0051] In some examples, the third plate 222 and the fourth plate 223 have the same shape and size, which facilitates processing.
[0052] In some examples, the third plate 222 and the fourth plate 223 have different shapes or sizes, such as the third plate 222 being longer than the fourth plate 223; or the third plate 222 being elliptical and the fourth plate 223 being elongated.
[0053] In this embodiment, the hammer head 22 is made of a relatively rotatable third plate 222 and a fourth plate 223. When encountering a foreign object, if the foreign object comes into contact with the third plate 222, even if the third plate 222 is blocked by the foreign object and cannot rotate along the predetermined trajectory, the fourth plate 223 can still move along the preset trajectory, improving work efficiency. If the hammer head 22 is a single plate, it will be unable to move along the set trajectory as long as it encounters a foreign object.
[0054] A second aspect of this application provides a shaving machine 100, including the aforementioned rotor assembly 10.
[0055] In some possible implementations, see [reference] Figure 2 , Figure 3The awn-removing machine 100 also includes a frame 30, which forms a working chamber 32 through multiple sealing plates 31. A sieve cylinder 37 is fixedly connected inside the working chamber 32, and the rotor assembly 10 passes through the sieve cylinder 37. The sieve cylinder 37 has sieve holes around its circumference.
[0056] In some examples, the frame 30 may be formed by welding or assembled using fasteners such as bolts and nuts.
[0057] In other examples, the cover plate 31 can be connected to the frame 30 by bolts or other components, or a portion of the cover plate 31 can be welded to the frame 30 while another portion of the cover plate 31 can be detachably connected to the frame 30, so as to facilitate inspection and maintenance of the working chamber 32.
[0058] In some examples, the drive shaft 1 of the rotor assembly 10 can be rotatably connected to the frame 30 via a bearing housing 33. One end of the drive shaft 1 is connected to the drive mechanism 20, enabling the drive mechanism 20 to rotate the drive shaft 1. The drive mechanism 20 can employ a motor and belt drive structure, connecting the motor and the drive shaft 1 via the belt drive.
[0059] In order to discharge waste, the screen cylinder 37 in this embodiment is shorter than the working chamber 32. A gap is provided between one end of the screen cylinder 37 and the sealing plate 31. A waste outlet 34 is provided below the gap. Waste falls through the gap between the screen cylinder 37 and the sealing plate 31 and enters the waste outlet 34 below.
[0060] In some examples, see Figure 3 The screen cylinder 37 is shorter than the working chamber 32 and is offset within the working chamber 32 along its length. In this way, one end of the screen cylinder 37 is roughly aligned with one end of the working chamber 32, while the other end of the screen cylinder 37 has a large gap with the other end of the working chamber 32 to facilitate the discharge of waste materials.
[0061] To facilitate the collection of crops, a discharge port 35 is provided at the bottom of the sieve cylinder 37, which is connected to the working chamber 32. After the crops pass through the sieve holes of the sieve cylinder 37, they are discharged through the discharge port 35.
[0062] In some examples, the number of discharge ports 35 can be one or two.
[0063] In some examples, a feed inlet 36 is provided on the side of the working chamber 32 away from the gap. Crops are fed into the working chamber 32 through the feed inlet 36, and the feed inlet 36 and the waste outlet 34 are located at opposite ends of the threshing machine 100, so that the crops are fully threshed as they pass through the working chamber 32, thereby improving efficiency.
[0064] A third aspect of this application provides a awn-beating system, including the rotor assembly 10 described above, and / or the awn-beating machine 100.
[0065] In some possible implementations, see [reference] Figure 4 The awn removal system also includes a cleaning screen 200, an air separator 300, a cyclone dust collector 400, and an airlock 500 connected in sequence via pipelines. The airlock 500 is connected below the cyclone dust collector 400, and the outlet of the airlock 500 corresponds to the inlet 36 of the awn removal machine 100.
[0066] In some examples, the awn removal system also includes a hoist 600, which lifts the crops to a certain height to facilitate their transport to other equipment.
[0067] In some specific examples, the crops are lifted to a certain height by the elevator 600 and conveyed to the cleaning screen 200 for preliminary screening to remove some impurities. The pre-screened crops are then conveyed to the air separator 300, where stones, wires, and other impurities are removed and discharged. The crops are then further conveyed to the cyclone dust collector 400 for dust removal. After dust removal, the crops are conveyed to the awn remover 100 through the airlock 500.
[0068] After the awns on the grain crops are removed by the rotation of the hammer head 22 inside the awn remover 100, the cleaned grain crops are then sorted through the sieve cylinder 37. The cleaned grain crops pass through the sieve holes of the sieve cylinder 37 and are discharged through the discharge port 35 for collection. Some slightly larger impurities, such as ropes, strips of cloth, and knots of grass, will fall out through the waste port 34 and be collected in woven bags. This increases output while saving labor, extending the service life of the equipment, and preventing damage to parts.
