[0032] The box frame 200 is arranged directly above the feeding tray 300, and a leg 400 is arranged between the feeding tray 300 and the edge of the box frame 200, the leg 400 can be one, two or more, and the number of the leg 400 is not limited by the present application.

Figure 1 The box frame 200 is arranged directly above the feeding tray 300, and a leg 400 is arranged between the feeding tray 300 and the edge of the box frame 200, the leg 400 can be one, two or more, and the number of the leg 400 is not limited by the present application. The upper end and the lower end of the box frame 200 are open for feeding and discharging of the agricultural products, and the box frame 200 can be configured as a rectangular frame as shown in the accompanying drawings, or as a columnar frame, and the shape of the box frame 200 is not limited by the present application.

[0033] The peeling main body mechanism 100 is arranged in the box frame 200 for peeling the agricultural products, and comprises a plurality of peeling units 10, a guide mechanism 20, a floating frame 30, and a torsion spring 22 and a tension spring 40. The plurality of peeling units 10 are arranged horizontally and circumferentially, each of which comprises an arm 12, a cylinder frame 114, a blade 111, a tooth shaft 112, and a motor 113. The arm 12 is formed by two arm bodies which are pivotally connected, so that the arm 12 can perform stretching action in the horizontal plane, thereby allowing the radial movement of the radial inner end of the arm 12. The cylinder frame 114 is pivotally connected to the radial inner end of the arm 12, and the axis of the cylinder frame 114 is substantially vertical. The blade 111 is pivotally connected to the radial inner side of the cylinder wall of the cylinder frame 114 and is located below the tooth part of the tooth shaft 112. A torsion spring (not shown) is arranged between the blade 111 and the cylinder frame 114, so that the blade 111 can be reset after pivoting, thereby allowing the blade 111 to abut against the surface of the agricultural product with a certain pre-tightening force. The motor 113 is arranged in the cylinder frame 114 for driving the tooth shaft 112 to rotate. The circumferentially arranged radial inner end of the blade 111 and the tooth shaft 112 of the peeling unit 10 define a hole 116 which allows the agricultural product to pass through. After the lower end of the agricultural product is inserted into the hole 116, the tooth shaft 112 is driven to rotate by the motor 113. The rotating tooth shaft 112 drives the agricultural product to rotate on one hand, so that the surface of the agricultural product is cut by the blade 111. On the other hand, the rotating tooth shaft 112 simultaneously drives the agricultural product to move downward, so that the whole agricultural product passes through the hole 116 and is cut by the blade 111. The cut agricultural product and the surface skin fall on the material falling disc 300.

[0034] The guiding mechanism 20 is located above the circumferentially arranged peeling units 10, and the guiding mechanism 20 comprises a plurality of guiding plates 21 corresponding to the peeling units 10 one by one, the guiding plates 21 can be configured in a substantially fan-shaped shape, the plurality of guiding plates 21 are circumferentially arranged and located above the corresponding peeling units 10, the radially inner end of the guiding plate 21 is pivoted with the cylinder frame 114 of the radially inner end of the peeling unit 10, preferably, a U-shaped plate strip 1141 bypassing the tooth shaft 112 is configured on the cylinder frame 114, the radially inner end of the guiding plate 21 is pivoted with the U-shaped plate strip 1141, the radially outer end of the guiding plate 21 is pivoted with the box frame 200 and a torsion spring 22 is installed therebetween, the torsion spring 22 enables the guiding plate 21 to be reset after being pivoted downward and has a reset tendency. The floating frame 30 is horizontally arranged in the box frame 200, and the floating frame 30 is slidingly matched with the box frame 200 to enable the floating frame 30 to slide in the vertical direction, for example, by arranging circumferentially arranged and vertically extending sliding rails 32 on the box frame 200 and matching the sliding block 31 installed on the floating frame 30 to enable the floating frame 30 to slide vertically. The radially outer end of the supporting arm 12 of all the peeling units 10 is pivoted on the floating frame 30, so that all the peeling units 10 can move up and down with the floating frame 30. The tension spring 40 is arranged between the floating frame 30 and the top of the box frame 200 to apply elastic tension to the floating frame 30, preferably, a plurality of tension springs 40 are circumferentially arranged between the floating frame 30 and the top of the box frame 200 to enable the floating frame 30 to be uniformly stressed.

[0035] When the device is in an unused state, the upward torsion of the torsion spring 22 of the tail of the guiding plate 21 to the guiding plate 21 and the upward tension of the tension spring 40 to the floating frame 30 enable the guiding plate 21 to be at a minimum inclination angle, at this time, the size of the hole 116 defined by the tooth shaft 112 and the blade 111 of the radially inner end of all the peeling units 10 is the smallest.

[0036] In the process of inserting the lower end of the agricultural product into the hole 116, the axial force exerted by the agricultural product on the radially inner end of the guide plate 21 and / or the tooth shaft 112 makes the peeling units 10 move downward synchronously with the floating frame 30, the hole 116 enveloped by the tooth shaft 112 and the blade 111 increases to adapt to the size of the agricultural product, and the elastic force exerted by the torsion spring 22 and the tension spring 40 is converted into the pre-tightening force of the tooth shaft 112 and the blade 111 on the agricultural product to achieve the axial driving of the agricultural product and the peeling of the agricultural product. Thus, the linkage relationship of the guide plate 21, the peeling unit 10 and the floating frame 30 is used to adapt to the radial size of the agricultural product for realizing the peeling processing of the agricultural products with a larger size range and a size variation range. In addition, the edges 211 of the radially inner ends of the circumferentially arranged guide plates 21 realize the centering of the agricultural product during peeling by limiting the agricultural product, thereby more effectively inhibiting the eccentric disturbance of the agricultural product. In addition, the tail of each peeling unit 10 is connected to the floating frame 30, which has the advantage that the radially inner end of each peeling unit 10 moves synchronously and by the same amount, and each guide plate 21 pivots synchronously and by the same angle, thereby avoiding the different elastic forces provided by the tension spring 40 and the torsion spring 22 or the different sliding and rotating resistances, which causes the related components to move unsynchronously, thereby reducing the peeling effect.

[0037] In some preferred structures, the radially inner side of each cylinder holder 114 is provided with a protrusion 115, which is located below the corresponding blade 111. The radially inner side of each cylinder holder 114 is circumferentially arranged, and the protrusion 115 realizes the centering of the agricultural product during peeling by limiting the agricultural product, thereby more effectively inhibiting the eccentric disturbance of the agricultural product.

[0038] In some preferred structures, a conical knife 50 is installed on the side wall of the box holder 200, which has an inwardly recessed conical wall with an opening formed thereon, the side edges of the opening forming a blade edge 51, and the edge of the conical knife 50 is provided with a gear ring 52. A motor 53 with a gear for engaging with the gear ring 52 is installed on the box holder 200, and the motor 53 drives the conical knife 50 to rotate by engaging the gear with the gear ring 52. The conical knife 50 is used to remove the skin on the end of the agricultural product after peeling by the peeling main body mechanism 100. The end of the agricultural product is placed on the conical knife 50, and the blade edge 51 on the conical knife 50 removes the skin on the end of the agricultural product by rotating.

[0039] In some preferred structures, an optical sensor 61 is installed on the top of the box holder 200, which is used to detect whether there is an agricultural product in the middle region of the box holder 200. If there is, the motor 113 is controlled to start to peel the agricultural product. If there is not, the motor 113 is controlled to stop running.

[0040] In some preferred structures, an optical sensor 62 is installed on the outer wall of the beveler 50, which penetrates the through hole of the beveler 50 towards the middle region of the beveler 50, and is used to detect whether there is a product inserted into the beveler 50, if so, the motor 53 is controlled to drive the beveler 50 to rotate to remove the skin of the end of the product, if not, the motor 53 is controlled to stop rotating.

[0041] In some preferred structures, a position sensor (such as a proximity switch, not shown) is installed in the box frame 200, which is used to detect the vertical position of the floating frame 30, and if the position sensor detects that the vertical frame is lowered to a position beyond the preset position, an alarm is triggered in response to the signal of the position sensor. In this way, an alarm is triggered when the hole 116 enveloped by the pin 112 and the blade 111 is beyond the allowable range, so as to avoid damage to related components due to forcing the hole 116 to be too large.

[0042] In some preferred structures, as shown in Figure 2 and Figure 3 , a touch switch 71 is arranged on the outer wall of the cylinder frame 114, and a braking mechanism is arranged between the floating frame 30 and the box frame 200. When the lower end of the product is inserted into the hole 116 by hand and contacts the blade 111, the blade 111 is twisted, and the twisted blade 111 contacts the touch switch 71 to send a control signal. Based on the set PLC control logic, the controller controls the braking mechanism to brake the floating frame 30 for a second-level braking time, for example, 0.5 to 2 seconds, and then releases the brake on the floating frame 30. When the floating frame 30 is braked, the downward movement of the floating frame 30 is limited, so that the hole 116 is difficult to increase, thereby giving the hand a feedback force, so as to inform the person not to continue to insert. In this way, the skin of the section near the lower end of the product can not be cut before it has passed through the hole 116, so that the section can not be cut. Preferably, the braking mechanism includes an electrostrictive block 72 installed on the floating frame 30 and a rack 73 installed on the box frame 200 and opposite to the electrostrictive block 72. The extension rod of the electrostrictive block 72 brakes the floating frame 30 by penetrating the floating frame 30 and abutting against the rack 73, and releases the brake on the floating frame 30 by retracting.
