Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product processing, and particularly relates to a clutch control mechanism for a torreya grandis peeling device. Background Art

[0002] Currently, most of the peeling of fresh torreya grandis fruits is done manually. Manual peeling is inefficient, and the current labor cost is high, resulting in a high cost throughout the cost chain. Especially when the purchase price of fresh torreya grandis fruits is low, the purchase price cannot cover the labor cost of manual peeling, reducing the enthusiasm of fruit farmers for harvesting, causing fresh torreya grandis fruits to rot in the fields, which is not conducive to the sustainable development of the torreya grandis fruit industry. In addition, manual peeling is slow. Sometimes, when the purchase volume is large, due to insufficient manpower, torreya grandis fruits will rot and be discarded.

[0003] Chinese Invention Patent (CN202010939825.5) discloses a torreya grandis peeling device with a screening function. Although it can peel off the torreya grandis fruit skin, its peeling is completed by two sharp cutter heads, which causes great damage to the torreya grandis fruit core and results in a large waste. At the same time, some fruit farmers use machines to peel fruits in the market. However, there is a problem with existing torreya grandis peeling machines. They bite off the green skin by impact force, and the disordered impact force will damage the "Xishi eyes" of torreya grandis, causing the torreya grandis fruits to be eroded by spoilage bacteria during the retting process, not only affecting the flavor and quality, but also generating toxic substances that affect health. Torreya grandis has a special structure with a pair of "Xishi eyes". The "Xishi eyes" connect the inside and outside of the fruit kernel. Damaging the "Xishi eyes" will allow spoilage bacteria to invade the torreya grandis fruit kernel and cause the torreya grandis fruit core to deteriorate. The present invention solves the above-mentioned disadvantages of manual peeling and existing torreya grandis peeling machines. The present invention has high production efficiency and high output, and does not damage the "Xishi eyes" during the peeling process. And it is also a silent production without generating noise pollution. However, during the production process, after the fresh torreya grandis fruits are peeled, the idling of the peeling rollers wastes electricity and generates noise. Summary of the Invention

[0004] The purpose of the present invention is to provide a clutch control mechanism for a torreya grandis peeling device to solve the problem of power waste caused by the idling of the peeling rollers.

[0005] To achieve the above object, the present invention provides the following technical solution: A clutch control mechanism for a torreya grandis peeling device, the torreya grandis peeling device includes a frame and a main cylinder disposed on the frame that can be driven to rotate. The main cylinder includes a plurality of peeling bins circumferentially arranged on the outer circle, and a peeling roller is disposed in the peeling bin;

[0006] On one side of the main cylinder, there is a large peeling input gear that can be driven to rotate. At the end of the peeling roller, there is a clutch assembly, which includes a clutch fixed sleeve, a clutch gear, and a clutch spring. The clutch gear meshes with the peeling input large gear. The clutch fixed sleeve is sleeved on the rotating shaft of the peeling roller. The compression of the clutch spring corresponds to the disconnection of the transmission between the clutch gear and the peeling roller.

[0007] On the frame, there is a main shaft snap ring backing plate fixed. The main shaft snap ring backing plate is in the shape of an annular ring with a section of notch at the upper part. When the clutch assembly passes through the main shaft snap ring backing plate, the clutch spring is compressed.

[0008] Preferably, the end faces of the clutch gear and the clutch fixed sleeve opposite to each other are respectively provided with mutually matching tooth profiles.

[0009] Preferably, the end of the clutch spring is connected with a pressing plate, and the pressing plate matches the inner edge of the main shaft snap ring backing plate.

[0010] Preferably, transition inclined surfaces are respectively provided at both ends of the main shaft snap ring backing plate close to the notch.

[0011] Preferably, the notch is located directly above the main shaft snap ring backing plate.

[0012] Preferably, a gear is provided at the end of the peeling roller far from the clutch assembly. At the relative lower part of the main cylinder, there is a nuclear discharging control gear in the shape of an arc segment. The nuclear discharging control gear matches the gear. When the peeling bin passes through the nuclear discharging control gear, the peeling roller rotates reversely and outward.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention realizes the stop operation of the peeling roller after peeling through the clutch structure, saves electricity, and can control the reverse rotation of the peeling roller through the rotation of the main cylinder and the nuclear discharging control gear during discharging to assist discharging.

Specific embodiments

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further specifically described below through embodiments.

[0022] Embodiment: A clutch control mechanism for a Chinese torreya peeling device, as Figures 1-6 shown, the Chinese torreya peeling device of this embodiment includes a frame 100, a main cylinder 2 is provided on the frame 100, the main cylinder 2 is driven by a main cylinder motor 21 to rotate integrally, and a plurality of peeling bins 3 are evenly distributed on the outer circumference of the main cylinder 2.

[0023] The peeling bin 3 is integrally strip-shaped, arranged along the axial direction of the main cylinder 2, and a pair of peeling rollers 31 and a turning roller 32 are arranged inside along the length direction. The pair of peeling rollers 31 are arranged at intervals, and the distance is greater than the size of the fruit pit and less than the size of the Chinese torreya green fruit. The two peeling rollers 31 rotate reversely towards the middle. When the Chinese torreya green fruit 1 enters the area between the two peeling rollers 31, it will be rolled into the middle of the two peeling rollers 31 for peeling. At the same time, the turning roller 32 rotates to continuously turn the Chinese torreya green fruit 1, so as to completely peel the peel of the Chinese torreya green fruit 1, and at the same time avoid jamming.

[0024] In this embodiment, the outer circumferences of the peeling roller 31 and the turning roller 32 are both provided with tooth profiles. Among them, the teeth of the peeling roller 31 are straight strip-shaped teeth distributed along the length direction, while the teeth of the turning roller 32 are spirally arranged on the outer circumferential surface. The tooth shapes, tooth numbers and tooth heights of the peeling roller 31 and the turning roller 32 are determined according to the size specifications of the Chinese torreya green fruit 1 to be peeled, and the diameters and lengths of the peeling roller 31 and the turning roller 32 are determined according to the production capacity. Of course, in other embodiments of the present invention, the outer surfaces of the peeling roller 31 and / or the turning roller 32 may not be provided with tooth profiles, but instead use a smooth surface or pattern with a high coefficient of friction.

[0025] In this embodiment, the two peeling rollers 31 and one turning roller 32 in the peeling bin 3 are linked to each other, so that only driving one of the rollers can make them rotate simultaneously. Specifically, the left ends of the rotating shafts of the two peeling rollers 31 are respectively provided with meshing gears, so that a pair of peeling rollers 31 can be linked in reverse; the left end of the rotating shaft of the turning roller 32 and one of the peeling rollers 31 are also respectively connected by gears, so that the turning roller 32 can be driven to rotate when the peeling roller 31 rotates. In addition, the radii of the end gears of the two peeling rollers 31 are different, so that there is a speed difference between the two peeling rollers 31 when they rotate. Through the speed difference, the torreya grandis fruits 1 can be rubbed while being rolled, improving the peeling effect.

[0026] Regarding the drive of the peeling roller 31, this embodiment adopts a clutch drive, so that the peeling roller 31 and the turning roller 32 stop operating when the peeling bin passes through the area that does not require peeling under the rotation of the main cylinder 2, in order to save electricity.

[0027] Specifically, a large peeling input gear 33 is provided on the right side of the main cylinder 2. The large peeling input gear 33 is connected with a peeling roller power sprocket, and the peeling roller power sprocket is driven by a peeling motor 310, so as to drive the large peeling input gear 33 to rotate. The right end of the rotating shaft of one of the peeling rollers 31 in each peeling bin 3 is provided with a jaw-type clutch assembly. The clutch assembly includes a clutch fixed sleeve 34, a clutch gear 35 and a clutch spring 36. The clutch fixed sleeve 34 is fixed to the end of the rotating shaft of the peeling roller 31. The clutch gear 35 is movably sleeved on the outside and meshes with the large peeling input gear 33. The left end face and the right end face of the clutch gear 35 are respectively provided with matching tooth profiles, and the movement of the clutch gear 35 corresponds to the deformation of the clutch spring 36.

[0028] Specifically, the left end of the clutch spring 36 is connected to a pressure plate 38. The pressure plate 38 is rotatably connected to the clutch gear 35 through a bearing. When the pressure plate 38 is subjected to an external force, the clutch spring 36 is compressed, and at the same time, the clutch gear 35 is driven to disengage from the clutch fixed sleeve 34. At this time, when the clutch gear 35 rotates, it will not drive the peeling roller 31 to rotate; when the pressure plate 38 is not subjected to an external force, the clutch gear 35 is clamped with the clutch fixed sleeve 34 under the elastic force of the clutch spring 36. At this time, when the clutch gear 35 rotates, it will drive the peeling roller 31 to rotate.

[0029] For the control of the clutch, in this embodiment, a main shaft snap ring backing plate 37 coaxial with the main cylinder 2 is fixedly arranged on the frame 100. The main shaft snap ring backing plate 37 is in the shape of an annular ring with a notch in the upper part. Its inner edge matches the pressure plate 38 on the left side of the clutch spring 36. When the pressure plate 38 passes through the notch section, the pressure plate 38 is not stressed and the clutch is in the engaged state. That is to say, the notch section of the main shaft snap ring backing plate 37 corresponds to the peeling area. When the peeling bin 3 passes through the peeling area, the peel of the torreya grandis fruits 1 is removed; when the pressure plate 38 passes through the non-notch section, the inner edge of the main shaft snap ring backing plate 37 will resist the pressure plate 38 to contract the clutch spring 36. At this time, the clutch is in the disengaged state. During this process, the peeling roller 31 and the turning roller 32 stop running, saving electricity.

[0030] In this embodiment, the notch is located within the range of 90° - 120° directly above the main shaft snap ring backing plate 37. This angle is the peeling area, and the peeling roller 31 stops running in other areas.

[0031] In this embodiment, transition slopes are respectively provided at both ends of the main shaft snap ring backing plate 37 near the notch to facilitate the smooth sliding of the pressure plate 38.

[0032] After the torreya grandis fruits 1 are peeled in the peeling area, the fruit kernels may be stuck between a pair of peeling rollers 31. Even after the peeling rollers 31 stop rotating, the fruit kernels may not fall off smoothly to complete the discharging. Therefore, in this embodiment, an arc-shaped kernel discharging control gear 39 is provided at the relatively lower part on the left side of the main cylinder 2. Its center is consistent with the axis of the main cylinder 2. The kernel discharging control gear 39 matches the end gear of one of the peeling rollers 31 in the peeling bin 3. When any peeling bin 3 rotates with the main cylinder 2 to the area where the kernel discharging control gear 39 is located, the end gear of one of the peeling rollers 31 in this peeling bin 3 will engage with the kernel discharging control gear 39, so as to realize the reverse rotation of the peeling roller 31 and make the fruit kernels fall off smoothly for discharging.

[0033] In this embodiment, the higher end of the kernel discharging control gear 39 is not higher than the axis height of the main cylinder 2, and the angle corresponding to the kernel discharging area is not greater than 90°.

[0034] The above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
