[0002] As a major food crop, corn is widely planted in various regions of our country, with a cumulative planting area of approximately 35 million hectares across the country. To ensure food security, the whole country attaches great importance to agriculture and grain production. Grain harvest is the hard-earned result of months of labor by farmers, and every grain should be stored in the granary. In the early stage of the harvest season, the moisture content of corn ears is high, and the friction between the husks is large. To improve the peeling rate, the peeling machine needs to run at a high speed; in the middle and late stages of the harvest season, the moisture content of corn ears is low, the friction between the husks is small, the husks are relatively easy to be torn off, and the corn kernels are also relatively dry and easy to fall off the ears. To reduce kernel loss while ensuring the peeling rate, the peeling machine needs to appropriately reduce the working speed.

[0003] In summary, during different harvest seasons, the moisture content of corn varies. When harvesting early, the moisture content of corn is high, and the peeling machine needs to run faster to peel cleanly; when harvesting later, the moisture content of corn is low, and if it still runs at a high speed, it is easy to cause corn kernels to fall off. Therefore, we need a peeling machine that can flexibly adjust its speed. Content of the Utility Model

[0045] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0046] Embodiment 1

[0047] During different harvesting seasons, the water content of corn varies. When harvesting early, the water content of corn is high, and in order to peel it cleanly, the peeling machine needs to run faster; when harvesting later, the water content of corn is low, and if it still runs at high speed, it is easy to cause the corn kernels to fall off.

[0048] Traditional peeling machines often cannot adapt well to this change. They either always run at high speed or can only be adjusted in a few fixed gears, which brings two problems:

[0049] 1. It cannot adjust the running speed of the peeling machine in real time according to the actual situation;

[0050] 2. The cost is high because a complex speed-changing mechanism is required.

[0051] In response to this, referring to Figures 1 - 5 、 Figure 8 This embodiment provides a stepless speed regulation structure for a peeling machine, which includes a power input shaft 1 and a peeling machine transmission shaft 3. The power input shaft 1 is used to transmit power to the peeling machine transmission shaft 3, and the power input shaft 1 can be driven by an engine or a motor; the peeling machine transmission shaft 3 is installed on the frame 12 of the peeling machine through at least two first bearing seats 10 and is used to transmit power to the peeling machine; actually, the first bearing seats 10 are respectively installed on the opposite sides of the frame 12, and the peeling machine transmission shaft 3 is rotatably installed on the frame 12 through these two first bearing seats 10. The power input shaft 1 drives the peeling machine transmission shaft 3 through its rotation and simultaneously drives the operation of the peeling machine. Therefore, the rotation speed of the peeling machine transmission shaft 3 directly affects the running speed (rotation speed) of the peeling machine.

[0052] The stepless speed regulation structure of the peeling machine further includes:

[0053] A stepless transmission shaft 2. The power input shaft 1 is connected and transmitted with the stepless transmission shaft 2. The connection and transmission between the power input shaft 1 and the stepless transmission shaft 2 can be realized through transmission forms such as belt 403 transmission, sprocket transmission or gear transmission. The stepless transmission shaft 2 is connected and transmitted with the peeling machine transmission shaft 3 through a pulley transmission assembly 4;

[0054] A stepless speed regulation unit, which is used to steplessly adjust the transmission ratio of the pulley transmission assembly 4, that is, the stepless speed regulation unit can realize stepless adjustment of the transmission ratio of the pulley transmission assembly 4, so as to achieve the purpose of stepless speed regulation of the peeling machine transmission shaft 3.

[0055] Specifically: The pulley drive assembly 4 includes a driving pulley 401, a driven pulley 402, and a belt 403; the pulley drive assembly 4 directly affects the rotation speed of the peeling machine drive shaft 3; the driving pulley 401 and the driven pulley 402 are connected and driven by the belt 403. Among them, the driven pulley 402 is installed on the peeling machine drive shaft 3. The driving pulley 401 includes a split fixed disk 4012 and a moving disk 4011. The fixed disk 4012 and the moving disk 4011 are respectively rotatably installed on the infinitely variable drive shaft 2. The infinitely variable drive shaft 2 is provided with a first limiting structure and a second limiting structure for axially limiting the fixed disk 4012. The moving disk 4011 is located between the fixed disk 4012 and the first limiting structure. A V-shaped groove 404 for installing the belt 403 is formed between the moving disk 4011 and the fixed disk 4012; the driving pulley 401 is a split V-grooved pulley, and this V-grooved pulley is evenly divided into left and right parts, namely the axially movable moving disk 4011 and the non-axially movable fixed disk 4012; the V-shaped groove in this V-grooved pulley is the V-shaped groove 404 formed between the fixed disk 4012 and the moving disk 4011.

[0056] In this embodiment, the infinitely variable speed unit includes:

[0057] An elastomer is installed between the moving disk 4011 and the first limiting structure. The elastomer can adopt a spring 6; one end of the spring 6 is fixedly connected or abutted to the first limiting structure, and the other end of the spring 6 is fixedly connected or abutted to the moving disk 4011;

[0058] The seat plate weldment 7 is rotatably connected to both the power input shaft 1 and the infinitely variable drive shaft 2 at the same time;

[0059] A telescopic unit, whose piston rod can extend or contract. One end of the telescopic unit is used for hinging to the frame 12, and the other end is hinged to the seat plate weldment 7, and is used to drive the seat plate weldment 7 to rotate around the power input shaft 1. Hinge seats 11 are respectively arranged at both ends of the telescopic unit, and both ends of it are respectively hinged to the frame 12 and the seat plate weldment 7 through the hinge seats 11. The rotation direction of the telescopic unit around the hinge seats 11 is the same as the rotation direction of the infinitely variable drive shaft 2.

[0060] In this embodiment, the telescopic unit can adopt a hydraulic cylinder 9, and can drive the rotation of the seat plate weldment 7 through hydraulic power, so as to change the diameter of the driving pulley 401 (it can also be said that the depth where the belt 403 is located in the V-shaped groove 404), realize the dynamic adjustment of the diameter of the driving pulley 401, and further adjust the working speed of the peeling machine. The spring 6 is used to maintain sufficient pressing force of the belt 403 when the seat plate weldment 7 does not rotate around the power input shaft 1, ensuring the stable operation of the transmission system; moreover, the spring 6 can, under the condition of ensuring that the transmission power of the transmission system remains unchanged, adjust the transmission ratio by increasing or decreasing the distance between the moving disk 4011 and the fixed disk 4012, so as to adjust the belt speed and the pressing force of the belt 403.

[0061] In fact, the piston rod of the hydraulic cylinder 9 can only extend and retract within a certain length (safety range) to avoid damaging the overall structure. That is, the piston rod of the hydraulic cylinder 9 has an initial position and an extreme position, and the length of the piston rod can only be between the initial position and the extreme position for stepless speed regulation. When the piston rod of the hydraulic cylinder 9 extends or retracts, it can overcome the pressing force generated by the belt 403, so that the belt 403 has an axial acting force on the moving disk 4011, thereby changing the diameter of the driving pulley 401 and realizing stepless adjustment of the rotation speed of the peeling machine. When the piston rod of the hydraulic cylinder 9 moves from the initial position to the extreme position, or when the hydraulic cylinder 9 drives the belt 403 to move from the initial state (initial position) to the extreme state (extreme position), the length difference of the belt 403 is not greater than 1 mm (the theoretical length difference of the belt 403 is not greater than 1 mm). Then the length change of the belt 403 is very small (not exceeding 1 mm), so that the belt 403 can always be kept tight and will not affect the normal operation of the peeling machine.

[0062] In this embodiment, the power input shaft 1 and the stepless transmission shaft 2 are connected and driven in the form of chain wheel transmission. Specifically, a driven sprocket 5 is arranged on the stepless transmission shaft 2, and the fixed disk 4012 and the driven sprocket 5 are assembled into a fixed disk assembly by bolts. The fixed disk assembly can be regarded as a whole. The second limiting structure adopts an axial positioning shoulder, and the axial positioning shoulder is installed on one side of the driven sprocket 5 for axially positioning the whole fixed disk assembly. A driving sprocket 101 is arranged on the power input shaft 1, and the driving sprocket 101 and the driven sprocket 5 are connected and driven by a chain to realize chain transmission.

[0063] The seat plate weldment 7 is a weldment composed of multiple integrated structures, which has a first plate portion 701, a second plate portion 702, a third plate portion 703, and a fourth plate portion 704. Among them, the first plate portion 701 and the second plate portion 702 are respectively rotatably mounted at both ends of the endless transmission shaft 2 through bearings. Specifically, the first plate portion 701 is rotatably mounted at one end of the endless transmission shaft 2 through the second bearing seat 8. The first plate portion 701 and the second bearing seat 8 are combined to form the first limiting structure. The first plate portion 701 is attached to the inner side of the second bearing seat and can be bolted to it through a plurality of bolt assemblies, and then can rotate on the endless transmission shaft 2 through the internal bearing. The second plate portion 702 is rotatably mounted at the other end of the endless transmission shaft 2 through the third bearing seat. Preferably, the spring 6 is located between the first plate portion 701 and the moving disk 4011, and both ends of the spring 6 are respectively abutted against the first plate portion 701 and the moving disk 4011. During the rotation of the seat plate weldment 7, due to the design of the first plate portion 701 and the second plate portion 702, both ends of the endless transmission shaft 2 are stressed simultaneously, and the seat plate weldment 7 rotates more smoothly. The third plate portion 703 and the fourth plate portion 704 are respectively rotatably mounted on the power input shaft 1 through bearings or the fourth bearing seat, and the driving sprocket 101 is located between the third plate portion 703 and the fourth plate portion 704.

[0064] In this embodiment, the fixed disk 4012 and the moving disk 4011 have the same structure and are symmetrically mounted on the endless transmission shaft 2. The inner sides of the fixed disk 4012 and the moving disk 4011 (this inner side is the side where they are close to each other) both have a frustum portion 405. The axial direction of the frustum portion 405 is the same as the axial direction of the endless transmission shaft 2. The side surface of the frustum portion 405 is a bevel surface. The bevel surfaces of the frustum portions 405 of the moving disk 4011 and the fixed disk 4012 are combined to form a V shape. Therefore, a V-shaped groove 404 for installing the belt 403 is formed between the frustum portion 405 of the fixed disk 4012 and the frustum portion 405 of the moving disk 4011. It should be noted that the spacing of the V-shaped groove 404 changes with the spacing between the moving disk 4011 and the fixed disk 4012. When the spacing between the moving disk 4011 and the fixed disk 4012 becomes larger, the spacing of the V-shaped groove 404 becomes larger.

[0065] This scheme designs a mechanical stepless speed regulation structure, which is used to adjust the speed of the peeling machine drive shaft 3 according to the moisture content of corn. When the peeling machine is adjusted in speed, the piston rod of the hydraulic cylinder 9 extends to drive the seat plate weld 7 to rotate around the power input shaft 1. During the rotation process, the seat plate weld 7 simultaneously pulls the stepless transmission shaft 2. The thrust of the cylinder is used to overcome the axial compression force generated by the belt 403. In order not to be stretched, the belt 403 exerts an axial force on the moving plate 4011. The axial force overcomes the force of the spring 6 to open the moving plate 4011 (the moving plate 4011 is away from the fixed plate 4012 and squeezes the spring 6), and the wheel diameter of the driving pulley 401 is correspondingly reduced, the transmission ratio is reduced, and the speed of the peeling machine is reduced. On the contrary, when the piston rod of the hydraulic cylinder 9 contracts, the axial force of the belt 403 on the moving plate 4011 decreases, and under the action of the spring 6 force, the distance between the moving plate 4011 and the fixed plate 4012 decreases, the wheel diameter of the driving pulley 401 increases accordingly, the transmission ratio increases, and the speed of the peeling machine increases. By changing the wheel diameter of the driving pulley 401, the transmission ratio can be changed, thereby achieving the purpose of stepless adjustment of the speed of the peeling machine.

[0066] Here is an explanation: after the moving plate 4011 moves away from the fixed plate 4012 and squeezes the elastic body, the gap between the fixed plate 4012 and the moving plate 4011 becomes larger, and the moving plate 4011 and the fixed plate 4012 move away from each other. Since the width of the belt 403 remains unchanged, the belt 403 moves evenly downward in the V-shaped groove 404 along the inclined surface in the V-shaped groove 404 toward a deeper position (by Figure 4 Transformed into Figure 6 , changing from the initial position to the limit position), in this uniform downward movement process, stepless speed change is achieved; in the process of uniform downward movement of the belt 403 in the V-groove 404, the distance between the belt 403 and the central axis of the active pulley 401 becomes smaller, so that the wheel diameter of the belt 403 on the active pulley 401 becomes smaller, which is equivalent to a reduction in the wheel diameter of the active pulley 401, a reduction in the transmission ratio, a reduction in the belt speed, and a reduction in the rotation speed of the peeling machine drive shaft 3; conversely, the rotation speed of the peeling machine drive shaft 3 increases; therefore, the wheel diameter of the active pulley 401 is changed by extending and retracting the hydraulic cylinder 9, so as to achieve the purpose of changing the transmission ratio and thus realizing stepless adjustment of the peeling machine speed.

[0067] The core of this technology is how to ensure that the belt 403 can still work smoothly when the "moving disc 4011" moves, as follows:

[0068] 1. When the moving plate 4011 moves, the length of the belt 403 changes very little (no more than 1 mm), so that the belt 403 is always tight and will not affect the normal operation of the peeling machine.

[0069] 2. The hydraulic cylinder 9 is used to control the movement of the moving plate 4011, so there is no need to change the length of the belt 403 itself, thus simplifying the entire structure.

[0070] 3. Through a carefully designed spring 6, the belt 403 can maintain sufficient pressing force on the shaft under any circumstances, thus ensuring stable power transmission.

[0071] Embodiment 2

[0072] The difference between this embodiment and Embodiment 1 is that: the spring 6 in this embodiment is arranged between the moving disk 4011 and the fixed disk 4012, and both ends of the spring 6 are respectively connected to the moving disk 4011 and the fixed disk 4012. Since the spring 6 is arranged between the moving disk 4011 and the fixed disk 4012 and has a certain length itself, the inclined surface of the frustum part 405 of the moving disk 4011 is extended inward to form a ring-shaped extension part 406. The extension part 406 of the moving disk 4011 and the extension part 406 of the fixed disk 4012 enclose a cavity, and the spring 6 is located in this cavity. When the moving disk 4011 and the fixed disk 4012 move away from each other, since the width of the belt 403 remains unchanged, then the belt 403 uniformly moves downward along the inclined surface in the V-shaped groove 404 towards a deeper position in the V-shaped groove 404 (from Figure 6 transforms into Figure 7 , changing from the initial position to the extreme position), and stepless speed change is achieved during this uniform downward movement process.

[0073] Embodiment 3

[0074] As Figure 8 , a peeling machine includes a frame 12, a peeling machine assembly 13 and a feeding and pressing assembly 14 installed on the frame 12, and also includes the stepless speed regulation structure of the peeling machine. Among them, the ear processing intermediate shaft of the peeling machine can be used as the power input shaft 1.

[0075] The main advantages of this application include: simple overall structure, stable transmission power, large speed regulation range and overload protection;

[0076] Simple structure and low cost: This application is only composed of parts such as belt pulleys, sprockets and shafts. Compared with a gearbox, it has the advantages of simple structure and stepless speed regulation. Compared with the combination of a hydraulic pump and a hydraulic motor, it has the advantages of simple structure and low cost.

[0077] Stable transmission power: The spring 6 is reasonably designed according to the transmission power, which can achieve stable power output of the system. By maintaining sufficient pressing force of the belt 403 through the spring 6, the smooth operation of the transmission system is ensured, and different working conditions are adapted by adjusting the spring 6.

[0078] Large speed regulation range: The moving disk 4011 is driven to move axially by the hydraulic cylinder 9, and the diameter of the driving belt pulley 401 can vary within a large range, and stepless speed regulation can also be achieved. The rotation speed of the peeling machine can smoothly transition from slow to fast.

[0079] Overload protection: This application has the protection function of belt drive overload slipping, which can ensure the safe operation of the system; during normal operation, the piston rod of the hydraulic cylinder 9 will only operate safely within the safe range between the initial position and the extreme position. Only in special cases, such as when the load is too large, the belt 403 will slip, thus avoiding damage to the machine and playing the role of overload protection.

[0080] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
