Description

Technical Field

[0001] This invention relates to the field of agricultural product processing technology, and more specifically, to a shape-following peeling device adapted to agricultural products of different shapes. Background Technology

[0002] Since ancient times, agricultural products have played an important and irreplaceable role in human survival and development.

[0003] Currently, there are two main methods for peeling agricultural products: traditional manual peeling and mechanical peeling. Both methods primarily involve removing the outer skin or peel from the surface of the agricultural product to obtain a purer product. While manual peeling is effective, it is slow and increases processing costs, while also posing certain safety and quality risks. Mechanical peeling, on the other hand, is significantly more efficient than manual peeling, reduces labor costs, and improves both the quality and yield of the agricultural product.

[0004] Because the circumference diameter of agricultural products varies from top to bottom, when processing agricultural products such as yams, radishes, and watermelons that require peeling, it is not possible to quickly locate and peel them based on the circumference diameter of the agricultural product. Therefore, it is extremely important to develop a contour-following peeling device that can adapt to agricultural products of different shapes. This device can improve the peeling efficiency of agricultural products and has strong practical significance for the development of agricultural product processing.

[0005] CN216453224U discloses a peeling machine for processing Chinese medicinal materials. It can manually adjust the mechanical structure to adapt to Chinese medicinal materials of different shapes and sizes for peeling operations. However, the operation is cumbersome, it cannot be automatically adjusted, and it cannot quickly and automatically position Chinese medicinal materials for peeling operations.

[0006] CN112401256A discloses a processing device for potato agricultural products, which can peel agricultural products and classify and collect them. However, the operation is also cumbersome, requiring manual fixation of the agricultural products before peeling.

[0007] CN211961700U discloses an adjustable watermelon peeling device, which can also manually adjust the mechanical structure to adapt to watermelons of different shapes and sizes for peeling operations, but the peeling precision is not high and it is easy to cause waste. Summary of the Invention

[0008] The purpose of this invention is to provide a shape-following peeling device that adapts to agricultural products of different shapes, so as to improve at least the above-mentioned problems.

[0009] To achieve the above objectives, the present invention provides a shape-following peeling device adapted to agricultural products of different shapes, specifically: It includes an upper housing, a lower housing fixedly connected to the upper housing, a power and transmission mechanism and a peeling diameter adjustment mechanism installed inside the upper housing and the lower housing, a peeling component connected to the lower end of the peeling diameter adjustment mechanism, a force sensor installed on the peeling component, a controller electrically connected to the force sensor, a driver a and a driver b electrically connected to the controller respectively, and a power supply electrically connected to both driver a and driver b. The power and transmission mechanism includes a power motor, a driving bevel gear connected to the output shaft of the power motor by a key, a driven bevel gear meshing with the driving bevel gear, a hollow shaft with one end connected to the driven bevel gear by a key, an input cylindrical gear connected to the other end of the hollow shaft by a key, several transmission cylindrical gears that are constantly meshed with the input cylindrical gear and are evenly distributed around the center of the input cylindrical gear, several output cylindrical gears that are constantly meshed with the transmission cylindrical gears, and a transmission shaft with its upper end connected to the transmission cylindrical gear by a key. The peeling diameter adjustment mechanism is installed below the power and transmission mechanism, and includes a diameter adjustment motor whose output shaft is fitted in the hollow shaft, a turntable coaxially fixedly connected to the output shaft of the diameter adjustment motor, and a base coaxially installed below the turntable. The lower end of the drive shaft is rotatably connected to the turntable.

[0010] Preferably, the bottom of the lower housing is provided with several straight groove slide rails of the same specification evenly distributed around the center; the outer periphery of the base is provided with several straight groove slide rails of the same specification evenly distributed around the center; the outer periphery of the turntable is provided with several arc-shaped groove slide rails of the same specification evenly distributed around the center; and the several peeling components respectively pass through the straight groove slide rails of the lower housing, the straight groove slide rails of the base, and the arc-shaped groove slide rails of the turntable.

[0011] Preferably, the peeling component is keyed to the central hole of the output cylindrical gear, the power motor is electrically connected to the driver b, and the diameter adjustment motor is electrically connected to the driver a.

[0012] Preferably, the plurality of peeling components always form a regular polygon.

[0013] Preferably, the distances between the center points of the two arcs of the straight groove slide rail of the lower housing, the straight groove slide rail of the base, and the arc groove slide rail of the turntable are equal.

[0014] Preferably, the input cylindrical gear and several transmission cylindrical gears are always in constant mesh, and the several transmission cylindrical gears are always in constant mesh with several output cylindrical gears, so that the peeling component can continuously obtain power when the whole device is in operation.

[0015] The beneficial effects of this invention are as follows:

[0016] The turntable and base designed in this invention cooperate with each other. Power is provided by a diameter-adjustable motor, which transmits power to the turntable, enabling the peeling component to move radially with high precision and synchronization between the slide rails of each slot. Combined with the force sensor installed on the shaft of the peeling component, the peeling component can always adhere to the surface of the agricultural product with a certain clamping force and ensure that the agricultural product is always in the center of the envelope of several peeling components as it enters along the axis of the peeling component, thus realizing high-precision contour peeling operation.

[0017] This invention utilizes the interaction between a power motor, a driving bevel gear, a driven bevel gear, a hollow shaft, a transmission shaft, an input cylindrical gear, a transmission cylindrical gear, and an output cylindrical gear to ensure that power is ultimately transmitted to the peeling component. This allows the peeling component to continuously receive power, enabling it to rotate and remove the outer skin of agricultural products, thus greatly enhancing work efficiency during operation.

[0018] This invention employs microcontroller control technology. By programming and setting the duty cycle of the microcontroller's PWM output, the current and voltage of the power motor are controlled, thereby changing the motor's speed and ultimately controlling the speed of the peeling component during operation. This achieves stepless adjustment of the peeling component's speed, allowing for the selection of an appropriate speed based on the peeling characteristics of different agricultural products. Simultaneously, the force sensor on the peeling component can sense the magnitude of the force during the clamping process and transmit the signal to the diameter adjustment motor via the controller and driver. The diameter adjustment motor receives the signal and immediately makes a judgment, thus adjusting the peeling component in real time and performing the peeling operation on the clamping area, thereby improving the automation level of the device.

Detailed implementation method:

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, a shape-following peeling device adapted to agricultural products of different shapes includes an upper box (2), a lower box (5) fixedly connected to the upper box (2), a power and transmission mechanism (4) and a peeling diameter adjustment mechanism (3) installed inside the upper box (2) and the lower box (5), a peeling component (1) connected to the lower end of the peeling diameter adjustment mechanism (3), a force sensor (6) installed on the peeling component (1), a controller (10) electrically connected to the force sensor (6), a driver a (8) and a driver b (9) electrically connected to the controller (10) respectively, and a power supply (7) electrically connected to both the driver a (8) and the driver b (9).

[0025] Furthermore, the bottom of the lower housing (5) is provided with several straight groove slide rails of the same specification evenly distributed around the center, the outer periphery of the base (301) is provided with several straight groove slide rails of the same specification evenly distributed around the center, and the outer periphery of the turntable (303) is provided with several arc-shaped groove slide rails of the same specification evenly distributed around the center. The several peeling components (1) respectively penetrate the straight groove slide rails of the lower housing (5), the straight groove slide rails of the base (301) and the arc-shaped groove slide rails of the turntable (303).

[0026] It should be noted that the peeling component (1) is connected to the middle hole of the output cylindrical gear (401) by a key, the power motor (407) is electrically connected to the driver b (9), and the diameter adjustment motor (302) is electrically connected to the driver a (8). The plurality of peeling parts (1) always form a regular polygon; Each shaft can achieve better rotation by installing bearings.

[0027] In one embodiment of the present invention, the power and transmission mechanism (4) includes a power motor (407), a driving bevel gear (406) connected to the output shaft of the power motor (407) by a key, a driven bevel gear (404) meshing with the driving bevel gear (406), a hollow shaft (405) connected to the driven bevel gear (404) by a key at one end, an input cylindrical gear (403) connected to the hollow shaft (405) by a key at the other end, a plurality of transmission cylindrical gears (408) constantly meshing with the input cylindrical gear (403) and evenly distributed around the center of the input cylindrical gear (403), a plurality of output cylindrical gears (401) constantly meshing with the transmission cylindrical gears (408), and a transmission shaft (402) whose upper end is connected to the transmission cylindrical gear (408) by a key.

[0028] During operation, the power supply (7) supplies power to the driver b (9). The controller (10) receives the signal and transmits the signal to the driver b (9). The driver b (9) drives the power motor (407) to move. Through the meshing of the active bevel gear (406) and the driven bevel gear (404), the power can be transmitted to the input cylindrical gear (403) on the hollow shaft (405). At the same time, through the meshing of the input cylindrical gear (403) and the transmission cylindrical gear (408), and the meshing of the transmission cylindrical gear (408) and the output cylindrical gear (401), the power is finally transmitted to the peeling component (1), so that the peeling component (1) can rotate and remove the skin of agricultural products to achieve the effect of rotational peeling.

[0029] In another embodiment of the present invention, the peeling diameter adjustment mechanism (3) is installed below the power and transmission mechanism (4), including a diameter adjustment motor (302) whose output shaft is mounted in the hollow shaft (405), a turntable (303) coaxially fixedly connected to the output shaft of the diameter adjustment motor (302), and a base (301) coaxially installed below the turntable (303). The lower end of the drive shaft (402) is rotatably connected to the turntable (303).

[0030] During operation, the power supply (7) supplies power to the driver a (8). The controller (10) receives the signal and transmits the signal to the driver a (8). The driver a (8) drives the diameter adjustment motor (302) to rotate forward and backward, so that the turntable (303) can rotate back and forth. The peeling component (1) can move back and forth linearly between the turntable (303) and the base (301), so that the peeling component (1) can quickly clamp the agricultural products. At the same time, the force sensor (6) on the peeling component (1) will sense the magnitude of the force during the process of the peeling component (1) clamping the agricultural products in real time and transmit the signal to the controller (10). The controller (10) receives the signal and makes a judgment on whether the area meets the peeling operation requirements and whether the peeling operation is completed. The peeling component (1) will also adjust in real time, working from a certain peeling area to the next peeling area until all peeling areas of the agricultural products are completed, achieving the shape adjustment peeling effect.

[0031] Working principle: When the device is in operation, the agricultural products that need to be peeled are fed along the axis of the peeling component (1). When the part that needs to be peeled enters the envelope of several peeling components (1), the power supply (7) supplies power to the driver a (8), and the controller (10) sends a command to the driver a (8). The driver a (8) drives the diameter adjustment motor (302) to rotate forward, thereby driving the turntable (303) to rotate forward, so that several peeling components (1) slide along the straight groove of the lower box (5) respectively. The linear groove slide rail of the rail and the arc groove slide rail of the turntable (303) move synchronously toward the direction of clamping the peeling part of the agricultural product. The peeling part (1) quickly approaches and clamps the peeling part of the agricultural product. At the same time, the force sensor (6) on the peeling part (1) will sense the magnitude of the force during the process of the peeling part (1) clamping the agricultural product in real time and transmit the clamping force signal to the controller (10). The controller (10) will determine whether the required peeling part is centered and clamped and whether the peeling operation has been completed based on the clamping force signal. If the agricultural product has been clamped in the envelope area of ​​several peeling parts (1) and needs to be peeled, the power supply (7) supplies power to the driver b (9), and the controller (10) sends a command to the driver b (9) to drive the power motor (407) to rotate. First, the power of the power motor (407) is transmitted to the input cylindrical gear (403) through the meshing motion of the active bevel gear (406) and the driven bevel gear (404). Then, the input cylindrical gear (403) meshes with several transmission cylindrical gears (408), and the transmission cylindrical gears (408) mesh with several output cylindrical gears (401) respectively, so that the power is finally transmitted to the peeling parts (1), so that the peeling parts (1) continuously obtain power and perform a rotating peeling operation on the surface of the agricultural product. When the controller (10) determines that peeling is complete based on the signal detected by the force sensor (6) during the peeling process, the controller (10) sends a command to the driver a (8) to reverse the diameter adjustment motor (302), thereby driving the turntable (303) to reverse the movement, so that several peeling parts (1) move synchronously towards the direction of releasing agricultural products along the straight groove slide rail of the lower box (5), the straight groove slide rail of the base (301) and the arc groove slide rail of the turntable (303), so as to allow the unpeeled part of the agricultural product to continue to enter. This is repeated until the peeling of the entire agricultural product is completed.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
