Description

Technical Field

[0001] The invention belongs to the field of grain shelling equipment, in particular to an electric adjustable grain shelling machine based on double-axis dynamic balance. Background Art

[0002] Grain shellers are special equipment that use mechanical action to remove the husks of grains and retain intact kernels. They belong to the core category of agricultural product primary processing machinery.

[0003] Traditional hulling machines typically use a fixed-gap design, meaning the distance between the grinding wheels cannot be adjusted, making it difficult to adapt to the physical characteristics of different grain types. For example, if the gap is too small, hard grains can be over-compressed, resulting in a high rate of broken rice. If the gap is too large, soft grains may not be fully hulled, resulting in a high rate of hull residue. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an electric adjustable grain sheller based on dual-axis dynamic balance to solve the problem that traditional shellers in the prior art usually adopt a fixed gap design, that is, the grinding wheel spacing cannot be adjusted, which makes it difficult to adapt to the physical properties of different types of grains.

[0013] The transmission wheel drives the transmission shaft to rotate under the drive of the external power device, thereby causing the rotating shaft to rotate accordingly;

[0014] The driving assembly drives the ferrule to move up and down, thereby causing the rotating shaft to drive the grinding wheel 2 to move up and down.

[0015] Preferably, the driving assembly includes a motor 1, an output end of the motor 1 is fixedly connected to a gear 1, an outer side of the gear 1 is meshed with a gear 2, and an outer side of the gear 2 is meshed with a rack;

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 3 As shown:

[0028] Embodiment 1: The present invention provides an electric adjustable grain shelling machine based on dual-axis dynamic balance, comprising a main body mechanism 1, a shelling mechanism 2, a transmission mechanism 3 and a lifting assembly 4:

[0029] The main body 1 includes a main mounting cylinder 11, the outer lower end of the main mounting cylinder 11 is fixedly connected to an outer mounting plate 12, a grinding wheel 13 is fixedly mounted on the lower side of the outer mounting plate 12, and a feed pipe 14 is also fixedly mounted on the upper side of the outer mounting plate 12;

[0030] A through hole 121 is formed on the outer mounting plate 12, a through hole 2 131 is formed on the grinding wheel 13, a temporary material storage tank 132 is formed at the bottom of the grinding wheel 13, and the feed pipe 14, the through hole 121, the through hole 2 131 and the temporary material storage tank 132 are interconnected;

[0031] The lifting assembly 4 drives the shelling mechanism 2 to slide up and down along the main installation cylinder 11. The transmission mechanism 3 is slidably connected to the shelling mechanism 2. The transmission mechanism 3 rotates under the drive of the external power device, thereby driving the shelling mechanism 2 to rotate.

[0032] As can be seen from the above, during operation, the external power device drives the transmission mechanism 3 to rotate, and the transmission mechanism 3 drives the shelling mechanism 2 slidably connected thereto to rotate;

[0033] At the same time, the lifting assembly 4 drives the shelling mechanism 2 to slide up and down along the main installation cylinder 11;

[0034] The grain enters from the feed pipe 14, passes through the through hole 121 on the outer mounting plate 12 and the through hole 2 131 on the grinding wheel 13 in turn, and falls into the temporary storage trough 132 at the bottom of the grinding wheel 13, and then the shelling operation is completed with the cooperation of the rotating shelling mechanism 2 and the grinding wheel 13.

[0035] like Figure 1 and Figure 4 As shown:

[0036] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the shelling mechanism 2 includes a rotating shaft 21, and a grinding wheel 22 is fixedly mounted on the lower end of the outer side of the rotating shaft 21;

[0037] The transmission mechanism 3 includes a transmission shaft 31 and a transmission wheel 32. One end of the transmission shaft 31 is fixedly embedded in the transmission wheel 32, and the other end of the transmission shaft 31 is slidably embedded in the rotating shaft 21.

[0038] The lifting assembly 4 includes a driving assembly 41 and a clamping sleeve 42;

[0039] The rotating shaft 21 is fixedly mounted on the ferrule 42 via a bearing, and the transmission shaft 31 is slidably connected to the rotating shaft 21;

[0040] The transmission wheel 32 is driven by an external power device to drive the transmission shaft 31 to rotate, thereby causing the rotating shaft 21 to rotate accordingly;

[0041] The driving assembly 41 drives the clamping sleeve 42 to move up and down, thereby causing the rotating shaft 21 to drive the grinding wheel 22 to move up and down.

[0042] Specifically, the driving assembly 41 includes a motor 1 411 , the output end of the motor 1 411 is fixedly connected to a gear 1 412 , the outer side of the gear 1 412 is meshed with a gear 2 413 , and the outer side of the gear 2 413 is meshed with a rack 414 ;

[0043] The second gear 413 is mounted on the housing of the first motor 411 via a rotating shaft, and the rack 414 is fixedly mounted on the outside of the sleeve 42 .

[0044] As can be seen from the above, during operation, the external power device drives the transmission wheel 32 to rotate, thereby driving the transmission shaft 31 fixedly engaged with it to rotate. Because the other end of the transmission shaft 31 is slidably engaged with the rotating shaft 21, when the transmission shaft 31 rotates, it drives the rotating shaft 21 to rotate along with it, causing the grinding wheel 22 fixedly mounted on the lower end of the outer side of the rotating shaft 21 to rotate together;

[0045] At the same time, motor 1 411 is started, and its output end drives gear 1 412 to rotate, gear 1 412 drives gear 2 413 engaged with it to rotate, and gear 2 413 drives rack 414 engaged with it to move up and down. Since rack 414 is fixedly mounted on the outside of sleeve 42, and rotating shaft 21 is fixedly mounted on sleeve 42 through bearing, the up and down movement of rack 414 will drive sleeve 42 to move up and down, and then the rotating shaft 21 drives grinding wheel 2 22 to move up and down, so that grinding wheel 2 22 can move up and down while rotating, and cooperate with grinding wheel 1 13 to complete the grain shelling operation.

[0046] like Figure 1 As shown:

[0047] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the external power device is motor 2, the transmission wheel 32 is a pulley, and motor 2 drives the pulley to rotate through a belt drive.

[0048] As can be seen from the above, when the motor 2 starts to run, its output shaft drives the belt that cooperates with it to rotate, and then the transmission wheel 32 rotates through the belt transmission. Since the transmission wheel 32 is fixedly engaged with the transmission shaft 31, it drives the transmission shaft 31 to rotate synchronously, and the other end of the transmission shaft 31 slides and engages with the rotating shaft 21, causing the rotating shaft 21 to rotate accordingly, and then the grinding wheel 22 fixed to the lower end of the rotating shaft 21 starts to rotate at high speed.
