Description

Technical Field

[0001] The present invention relates to the field of non-destructive testing of crops, and specifically to a non-destructive testing device for garlic. Background Art

[0002] After garlic is harvested, it needs to be transported to a cold storage for fresh storage. Before entering the cold storage for storage, certain treatments need to be carried out on the garlic, such as drying, sterilization, pre-cooling treatment, etc. When bagging, it is also necessary to detect whether the garlic bulbs are damaged, because the damaged positions are prone to breed fungi, and the fungi parasitized inside the damaged positions are not easily killed during the sterilization treatment. The bacteria breeding at the damaged positions will grow continuously during storage, which will cause serious adverse effects on the storage of garlic.

[0003] At present, most garlic bagging uses a mechanical automatic bagging line, and a damage detection device with non-destructive testing function is set in the line. However, due to design defects, the reliability of the detection results of the damage detection device is relatively low, and it still cannot well ensure that the garlic bulbs enter the warehouse without bacteria. Summary of the Invention

[0004] To improve the reliability of the non-destructive testing function, the present invention provides a non-destructive testing device for garlic, which can achieve comprehensive detection of each garlic bulb and improve the reliability of the non-destructive testing results.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a non-destructive testing device for garlic, including a machine base and a leakage pipe oppositely arranged on the upper part of the machine base. The garlic bulbs can only be stacked in a single row in the lumen of the leakage pipe. A sleeve is provided at the upper end of the machine base. The sleeve is matched with the machine base through a bearing, and a detector is provided in the upper part of the inner cavity of the sleeve, and an external gear is provided at the lower part of the outer wall. The axial length of the sleeve is not less than 1.2 to 1.8 times the height of the garlic bulb. There is a spacing between the lower end surface of the leakage pipe and the upper end surface of the sleeve.

[0006] A power group one capable of driving the sleeve to rotate is provided on the machine base, and the gear provided in the power group one meshes with the external gear at the lower part of the sleeve. A sliding seat capable of ascending and descending in the vertical direction relative to the machine base is provided on the machine base, and a support platform for supporting the garlic bulb is provided at the upper end of the sliding seat.

[0007] A power group two capable of driving the sliding seat to ascend and descend is provided on the machine base, and under the drive of the power group two, the support platform can extend into and out of the lumen of the sleeve. Generally, when the support platform moves to the highest position in the lumen of the sleeve, it is at the upper-middle position of the lumen of the sleeve. Specifically, it needs to be adjusted according to the position of the set detector to ensure that the detector has a wide and comprehensive view of the garlic bulb directly placed on the support platform.

[0008] It further includes two sets of pushing mechanisms, each set of pushing mechanisms is matched with a conveyor belt, and the matched pushing mechanism and conveyor belt are respectively arranged on the left and right sides and the front and back sides of the sliding seat. The pushing mechanism can drag the garlic cloves in contact with the supporting table to the corresponding conveyor belt when the supporting table moves to below the sleeve.

[0009] Furthermore, the pushing mechanism includes a sliding plate matched with the machine base through a linear slide rail, a seat plate arranged at the inner end of the sliding plate, and a pair of clamping arms. A transmission group for driving the sliding plate to move linearly back and forth relative to the machine base is arranged on the machine base. The clamping arms are matched with the seat plate through slide rails, and a driving mechanism capable of driving the clamping arms to move away from and towards each other is arranged on the seat plate. Preferably, the driving mechanism can be a hydraulic cylinder or a pneumatic cylinder driving mechanism. The part of the clamping arms extending relatively outside the seat plate is L-shaped, and the free end of the L-shaped part is provided with a V-shaped clamping jaw. The two end parts of the claw plates of the V-shaped clamping jaw extend outwards and form an obtuse angle with the main body of the claw plate.

[0010] Preferably, the transmission group for driving the sliding plate to move linearly back and forth relative to the machine base is a gear-rack transmission group, and the rack is arranged on the sliding plate.

[0011] Furthermore, the second power group includes a motor and a lead screw; the motor is fixed on the machine base, and the lead screw is matched with the sliding seat to form a lead screw-slider unit.

[0012] Furthermore, an end cylinder is arranged at the lower end of the leakage pipe, and an elastic layer is attached to the inner wall of the end cylinder.

[0013] The beneficial effects of the present invention are: this kind of garlic non-destructive detection device can achieve comprehensive detection of each garlic clove, improve the reliability of non-destructive detection results, effectively avoid damaged garlic cloves from entering the storage, contribute to improving the storage quality of garlic, and reduce the amount of storage damage.

At the same time, the terms such as "upper", "lower", "front", "rear", "middle" and the like cited in this specification are only for the convenience of clear narration and are not used to limit the scope for the implementation of the present invention. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope for the implementation of the present invention.

[0019] As Figure 1 shown, a garlic non-destructive detection device includes a base 1 and a leakage pipe 2 oppositely arranged on the upper part of the base 1. The garlic bulbs 10 can only be stacked in a single row in the lumen of the leakage pipe 2. The upper end of the base 1 is provided with a sleeve 3 with its axis along the vertical direction. The sleeve 3 is matched with the base 1 through a bearing, and a detector 31 is provided in the upper part of the inner cavity of the sleeve 3, and an external gear is provided at the lower part of the outer wall. The axial length of the sleeve 3 is not less than 1.2 to 1.8 times the height of the garlic bulb 10, preferably in the range of 1.5 times to 1.65 times. When calculating the height of the garlic bulb, it is calculated as the average height of the garlic bulbs of the same specification (the specification of the garlic bulb is set according to the outer diameter of the garlic bulb). There is a certain distance between the lower end surface of the leakage pipe 2 and the upper end surface of the sleeve 3. This distance should not be too large, as long as it can ensure that the leakage pipe 2 does not interfere with the rotation of the sleeve 3 and can discharge the fallen garlic skins.

[0020] As Figure 1 、 Figure 3 shown, a power unit one 4 capable of driving the sleeve 3 to rotate is provided on the base 1. The gear 41 provided in the power unit one 4 meshes with the external gear at the lower part of the sleeve 3. The first motor 42 in the power unit one 4 is matched with the gear 41 through a gearbox.

[0021] As Figure 1 、 Figure 3As shown, a sliding seat 5 capable of lifting and lowering relative to the machine base 1 in the vertical direction is provided on the machine base 1, and a support platform 51 for holding garlic bulbs is provided at the upper end of the sliding seat 5. A second power group 6 capable of driving the sliding seat 5 to lift and lower is provided on the machine base 1, and under the drive of the second power group 6, the support platform 51 can extend into and out of the sleeve 3 (as Figure 3 shown). In some embodiments, the second power group 6 includes a second motor 61 and a lead screw 62. The second motor 61 is fixed on the machine base 1, and the lead screw 62 is matched with the sliding seat 5 to form a lead screw-slider unit.

[0022] As Figure 1 , Figure 3 shown, two sets of pushing mechanisms 7 are further included. Each set of pushing mechanisms 7 is matched with a conveyor belt 8, and the matched pushing mechanisms 7 and conveyor belts 8 are respectively arranged on the left and right sides and the front and rear sides of the sliding seat 5. The pushing mechanism 7 can drag the garlic bulb 10 in contact with the support platform 51 onto the corresponding conveyor belt 8 when the support platform 51 moves below the sleeve 3.

[0023] To effectively adjust the position where the garlic bulb 10 falls on the support platform 51 and strive to make the garlic bulb 10 fall at the center of the upper end face of the support platform 51, an end cylinder 21 is provided at the lower end of the leakage pipe 2, and an elastic layer 211 made of sponge material or similar material is attached to the inner wall of the end cylinder 21.

[0024] As Figure 1 , Figure 3 shown, a set of pushing mechanism 7 and conveyor belt 8 arranged on the left and right sides of the sliding seat 5 are fully shown, and only the pushing mechanism of a set of pushing mechanisms and conveyor belts arranged on the front and rear sides is shown.

[0025] During use, a control unit is matched with the garlic non-destructive detection device disclosed in this patent, and the control unit preferably has a programming module. When all mechanical mechanisms are in the initial position (the control program is reset to the original position), the first garlic bulb 10 falling from the leakage pipe 2 onto the support platform 51 is first detected for damage. While the sleeve 3 rotates relative to the sliding seat 5, the detector 31 rotates around the garlic bulb 10 for a full circle to perform a full-range detection on the garlic bulb 10 for whether there are damage scars. The detector 31 can adopt a video collector that is currently used more. At this time, the control unit contains an intelligent chip to analyze the collected images to judge whether there is damage to the garlic bulb 10.

[0026] As Figure 3As shown, after the first garlic bulb 10 is detected, the sliding seat 5 moves downward relative to the sleeve 3 by a certain distance, so that the second garlic bulb 10 falls within the detection area of the detector 31. After the detector 31 surrounds the second garlic bulb 10 for one week, the sliding seat 5 moves downward by a certain distance again, so that the third garlic bulb 10 falls within the detection area of the detector 31. After the detector 31 surrounds the third garlic bulb 10 for one week, the pushing mechanism 7 moves the first garlic bulb 10 onto the corresponding conveyor belt 8. If it is set that when the garlic bulb has no damage, a set of pushing and conveying mechanisms distributed on the left and right sides of the sliding seat 5 and the conveyor belt act, and on the contrary, when the garlic bulb has damage, a set of pushing and conveying mechanisms distributed on the front and rear sides of the sliding seat 5 and the conveyor belt act, then if the first garlic bulb 10 is analyzed to have no damage after analysis, it will be transferred to the conveyor belt arranged on the left side of the sliding seat for output (the upper end of the conveyor belt surface is basically flush with the upper end surface when the support table 51 is transferred to the lowest position, and preferably the height of the former is slightly lower than that of the latter). After the first garlic bulb 10 is transferred onto the conveyor belt, the fourth garlic bulb 10 falls within the detection area of the detector 31. After the detector 31 surrounds the fourth garlic bulb 10 for one week, the pushing mechanism 7 moves the second garlic bulb 10 onto the corresponding conveyor belt 8. If the second garlic bulb 10 is analyzed to have no damage after analysis, it will be transferred to the conveyor belt arranged on the left side of the sliding seat for output, and if it has damage, it will be transferred to the conveyor belt arranged on the front side of the sliding seat for output. After the second garlic bulb 10 is transferred onto the conveyor belt, the fifth garlic bulb 10 falls within the detection area of the detector 31, and the above process is repeated.

[0027] It should be noted that the implementation of the disclosed solution of this patent requires a control unit. The specific implementation manner of the control unit can be obtained from the prior art according to the mechanical structure set in this patent and the action purposes of each part, and then the design can be completed. When those skilled in the art obtain the mechanical structure and the action requirements of each part disclosed in this patent document, they can design different forms of control units according to the guidance of the patent document. Therefore, the control unit does not belong to the part protected by this patent, so it will not be described in detail.

[0028] As Figure 2 As shown, the pushing mechanism 7 includes a sliding plate 71 that matches the machine base 1 through a linear slide rail, a seat plate 72 provided at the inner end of the sliding plate 71 (the end close to the sliding seat 5), and a pair of clamping arms 73. A transmission group for driving the sliding plate 71 to move linearly back and forth relative to the machine base 1 is provided on the machine base 1. In the illustrated embodiment, this transmission group can be set as a gear-rack transmission group 711, and the rack is provided on the sliding plate 71.

[0029] The clamping arm 73 is matched with the seat plate 72 through a slide rail, and a driving mechanism 721 capable of driving the clamping arm 73 to move away from and towards each other is provided on the seat plate 72. Preferably, the driving mechanism 721 can be a hydraulic cylinder or a pneumatic cylinder driving mechanism. A section of the clamping arm 73 extending relatively outside the seat plate 72 is L-shaped, and a V-shaped clamping jaw is provided at the free end of the L-shaped part. The two end portions of the V-shaped clamping jaw extend outwards and form an obtuse angle with the main body of the jaw plate. When clamping the garlic bulb, the outer wall of the garlic bulb contacts the arc surface at the obtuse angle position. Preferably, an elastic layer is attached to the surface of the clamping jaw, which can not only increase the reliability of clamping but also prevent the garlic bulb from being bruised due to excessive clamping force.

[0030] In some embodiments, among the two sets of pushing mechanisms 7, for the pushing mechanisms arranged on the left and right sides of the sliding seat 5, the moving direction of the sliding plate 71 is linear sliding left and right, and the moving direction of the clamping arm 73 provided on the seat plate is linear sliding back and forth. When the clamping arm placed relatively on the front side moves forward, the clamping arm placed relatively on the rear side moves backward (releasing the clamping action on the garlic bulb); conversely, when the clamping arm placed relatively on the front side moves backward, the clamping arm placed relatively on the rear side moves forward (clamping the garlic bulb). For the pushing mechanisms arranged on the front and rear sides of the sliding seat 5, the moving direction of the sliding plate 71 is linear sliding back and forth, and the moving direction of the clamping arm 73 provided on the seat plate is linear sliding left and right. When the clamping arm placed relatively on the left side moves left, the clamping arm placed relatively on the right side moves right (releasing the clamping action on the garlic bulb); conversely, when the clamping arm placed relatively on the left side moves right, the clamping arm placed relatively on the right side moves left (clamping the garlic bulb).

[0031] The above embodiments are only illustrative of the principles and effects of the present invention, rather than limiting the present invention. There are many aspects of the present invention that can be improved without departing from the overall idea. Those familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
