Technical Field
[0001] This utility model relates to the field of barley kernel hulling machines, specifically a shock absorption and noise reduction mechanism for barley kernel hulling machines. Background Technology
[0002] A barley hulling machine (also known as a barley dehulling machine) is an agricultural machine used to remove the husks (outer skin) of barley. Its core principle is to separate the husks from the kernels through physical action while minimizing damage to the kernels.
[0003] In the prior art, Chinese Patent Application No. CN201721262220.7 discloses a peeling machine, including a frame with several sets of driving rollers and driven rollers within the frame. There is a gap between the driving rollers and driven rollers in the same set. The outer circumferential walls of both the driving rollers and driven rollers are covered with peeling cloth. One end of each driving roller has a first gear, and one end of each driven roller has a second gear. Several third gears are provided on the frame. The first gear at the end of the driving roller is connected to the second gear at the end of the driven roller in the same set via at least one third gear. The first gears at the ends of adjacent sets of driving rollers are connected via third gears. A drive source is located at the bottom of the frame, and the other end of one of the driving rollers in the several sets is connected to the drive source. This peeling machine has the advantage of high peeling efficiency.
[0004] However, when using the existing peeling machine as a barley kernel hulling machine, the lack of a vibration damping and noise reduction mechanism between the drive source and the frame causes excessive knocking between the drive source and the frame during operation, resulting in excessive vibration and noise.

[0013] The vibration reduction and noise reduction mechanism for the barley kernel hulling machine proposed in this utility model has the following characteristics: When the drive source is running, the vibration emitted by the drive source is buffered by the second pad before being transmitted to the mounting plate. The mounting plate is rotatably connected to the mounting seat fixed to the surface of the frame. A support leg is fixed to the bottom of the mounting plate, and a first rubber pad is fixed to the bottom of the support leg. Most of the vibration on the mounting plate is transmitted to the support leg and the first rubber pad. After being buffered by the first rubber pad, it is transmitted to the ground. The remaining part is transmitted from the mounting plate to the mounting seat and the frame. The mounting seat and the mounting plate are rotatably connected by a rotating shaft and a shaft hole. During vibration, the friction between the rotating shaft and the shaft hole buffers part of the vibration. The buffered vibration is transmitted to the frame. Through the above structure, the vibration generated by the drive source during operation and the impact between it and other components are reduced, thereby playing a role in vibration reduction and noise reduction. A push plate is fixedly fitted on the screw rod. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a shock absorption and noise reduction mechanism for a barley kernel hulling machine, comprising: a frame 1 and a drive source 2. A mounting base 3 is fixed on the surface of the frame 1, and a mounting plate 4 is rotatably connected to the surface of the mounting base 3. The drive source 2 is movably mounted on the mounting plate 4. A support leg 5 is fixed at the bottom end of the mounting plate 4, and a first rubber pad 6 is fixed at the bottom end of the support leg 5. A pad groove 9 is opened on the surface of the mounting plate 4, and a second pad 10 is movably installed in the pad groove 9.
[0022] In actual use, when the drive source 2 is running, the vibration emitted by the drive source 2 is buffered by the second pad 10 before being transmitted to the mounting plate 4. The mounting plate 4 is rotatably connected to the mounting seat 3 fixed on the surface of the frame 1. The bottom end of the mounting plate 4 is fixed with a support leg 5, and the bottom end of the support leg 5 is fixed with a first rubber pad 6. Most of the vibration on the mounting plate 4 is transmitted to the support leg 5 and the first rubber pad 6. After being buffered by the first rubber pad 6, it is transmitted to the ground. The remaining part is transmitted from the mounting plate 4 to the mounting seat 3 and the frame 1. The mounting seat 3 and the mounting plate 4 are rotatably connected through a rotating shaft and a shaft hole. During vibration, the friction between the rotating shaft and the shaft hole buffers part of the vibration. The buffered vibration is transmitted to the frame 1. Through the above structure, the vibration generated by the drive source 2 during operation and the impact between it and other components are reduced, thereby playing the role of vibration reduction and noise reduction. A push plate 13 is fixedly fitted on the rod body of the screw 8.
[0023] Example 2: Based on Example 1, in order to install the drive source 2 and the mounting plate 4, a screw hole 7 is provided on the surface of the mounting plate 4. A screw rod 8 is installed in the screw hole 7 by a threaded connection. A first nut 11 and a second nut 12 are respectively installed at both ends of the screw rod 8 by a threaded connection. The first nut 11 abuts against the bottom end of the mounting plate 4, and the second nut 12 abuts against the top end of the drive source 2.
[0024] When installing the drive source 2 onto the mounting plate 4, first install the second washer 10 in the washer groove 9, then install the screw 8 from above into the screw hole 7 via a threaded connection until the push plate 13 is pressed against the top of the second washer 10. Then install the first nut 11 from below onto the screw 8 via a threaded connection, so that the screw 8 is more securely installed in the screw hole 7. After that, install the second nut 12 from above the screw 8 via a threaded connection until the bottom end of the second nut 12 is tightened onto the top of the drive source 2, thus completing the installation between the drive source 2 and the mounting plate 4.
[0025] Example 3: Based on Example 2, in order to facilitate the replacement of the second gasket 10, a push plate 13 is fixedly fitted on the rod body of the screw 8, and a detachable handle 14 is movably installed at the bottom end of the screw 8 by means of a screw and nut. A clearance hole 15 is opened on the surface of the second gasket 10, and a handle 16 is fixed on the other end surface of the second gasket 10.
[0026] After the installation of the drive source 2 and the mounting plate 4 is completed, the detachable handle 14 is installed at the bottom of the screw 8. The second washer 10 is in direct contact with the drive source 2 and is subjected to the severe vibration of the drive source 2 for a long time, which causes the second washer 10 to age quickly and have a short service life, requiring frequent replacement. When replacing it, it is often necessary to remove the drive source 2, replace it, and then reinstall the drive source 2 on the mounting plate 4. The removal and installation of the drive source 2 requires the re-laying of the belt, which is very time-consuming and laborious. In this utility model, when the second washer 10 needs to be replaced, the first nut 11 is slightly loosened downwards, and then the screw 8 is rotated through the detachable handle 14. Through the threaded connection between the screw 8 and the screw hole 7, the screw 8 is moved upwards, and the movement of the screw 8 drives the push plate 13 upwards. The push plate 13 pushes the drive source 2 upward, causing it to move slightly away from the top of the second washer 10. Then, the handle 16 is pinched to pull the old second washer 10 out of the washer groove 9. After that, the new second washer 10 is inserted into the washer groove 9. The surface of the second washer 10 has a clearance hole 15 to prevent the screw 8 from affecting the insertion and removal of the second washer 10. After the new second washer 10 is inserted into the washer groove 9, the screw 8 is turned in the opposite direction to make the push plate 13 press the top of the new second washer 10 again. Finally, the first nut 11 is turned in the opposite direction to tighten the first nut 11 to the bottom of the mounting plate 4. The replacement of the second washer 10 can be completed without disassembling the drive source 2, making the replacement of the second washer 10 more convenient.
[0027] In actual use, when the drive source 2 is running, the vibration emitted by the drive source 2 is buffered by the second pad 10 before being transmitted to the mounting plate 4. The mounting plate 4 is rotatably connected to the mounting base 3 fixed to the surface of the frame 1. A support leg 5 is fixed to the bottom end of the mounting plate 4, and a first rubber pad 6 is fixed to the bottom end of the support leg 5. Most of the vibration on the mounting plate 4 is transmitted to the support leg 5 and the first rubber pad 6, and after being buffered by the first rubber pad 6, it is transmitted to the ground. The remaining part is transmitted from the mounting plate 4 to the mounting base 3 and the frame 1. The mounting base 3 and the mounting plate 4 are rotatably connected through a rotating shaft and a shaft hole. During vibration, the friction between the rotating shaft and the shaft hole buffers part of the vibration, and the buffered vibration is transmitted to the frame 1. Through the above structure, the drive source 2 is able to operate smoothly. The resulting vibrations are reduced, thus mitigating impacts with other components and reducing noise. A push plate 13 is fitted and fixed onto the rod body of the screw 8. When installing the drive source 2 onto the mounting plate 4, first install the second washer 10 in the washer groove 9, then install the screw 8 from above into the screw hole 7 via a threaded connection until the push plate 13 is pressed against the top of the second washer 10. Then, install the first nut 11 from below onto the screw 8 via a threaded connection, making the screw 8 more securely installed in the screw hole 7. After that, install the second nut 12 from above onto the screw 8 via a threaded connection until the bottom end of the second nut 12 is tightened onto the top of the drive source 2. This completes the installation between the drive source 2 and the mounting plate 4. After the plate 4 is installed, the detachable handle 14 is installed at the bottom of the screw 8. The second washer 10 is in direct contact with the drive source 2 and is subjected to the severe vibration of the drive source 2 for a long time, which causes the second washer 10 to age quickly and have a short service life, requiring frequent replacement. When replacing it, it is often necessary to remove the drive source 2, replace it, and then reinstall the drive source 2 on the mounting plate 4. The removal and installation of the drive source 2 requires the re-laying of the belt, which is very time-consuming and laborious. In this utility model, when the second washer 10 needs to be replaced, the first nut 11 is slightly loosened downwards, and then the screw 8 is rotated through the detachable handle 14. Through the threaded connection between the screw 8 and the screw hole 7, the screw 8 is moved upwards. The movement of the screw 8 drives the push plate 13 upwards, pushing it upwards. Plate 13 pushes the drive source 2 upward, causing it to move slightly away from the top of the second washer 10. Then, the handle 16 is pinched to pull the old second washer 10 out of the washer groove 9. After that, the new second washer 10 is inserted into the washer groove 9. The surface of the second washer 10 has a clearance hole 15 to prevent the screw 8 from affecting the insertion and removal of the second washer 10. After the new second washer 10 is inserted into the washer groove 9, the screw 8 is turned in the opposite direction to make the push plate 13 press back onto the top of the new second washer 10. Finally, the first nut 11 is turned in the opposite direction to tighten it to the bottom of the mounting plate 4. The replacement of the second washer 10 is completed. The replacement of the second washer 10 does not require disassembling the drive source 2, making the replacement of the second washer 10 more convenient.
