Technical Field
[0001] The utility model relates to the technical field of fruit and vegetable sorting, in particular to a material guiding component and a fruit and vegetable sorting device. Background Art
[0002] In recent years, with the development of agricultural science and technology and the improvement of people's living standards, there are more and more varieties of fruits and vegetables, and people have higher requirements for the quality of fruits and vegetables. In order to improve the processing quality and product grade of fruits and vegetables, it is necessary to strictly grade fruits and vegetables by quality and size. Most of the existing fruit and vegetable sorting machines have complex structures, and are generally based on large-scale production lines, with high manufacturing costs, low sorting efficiency, and high sorting costs. The existing fruit and vegetable sorting machines are mainly weight sorting machines, and the sales of fruits and vegetables in agricultural product bases are mostly based on size and texture. Weight sorting machines are not suitable for use in agricultural product bases. Early weight sorting mechanical equipment used the principle of levers to sort fruits and vegetables by weight, and mostly used fixed weighing scales, fixed limit devices, mobile conveyor trays, and mobile weighing scales to sort fruits and vegetables by weight. These types of mechanized weight sorting equipment have little damage to fruits and vegetables and are widely versatile, but due to the influence of various factors during the sorting process, the sorting accuracy is not high.
[0003] Among them, the most widely used fruit and vegetable sorting machine is the size sorting machine, which mainly uses the drum sorting method to sort round fruits and vegetables. Because of its simple structure, low price and low comprehensive maintenance cost. However, these sorting machines mainly rely on gravity to achieve forward transportation, so the efficiency of sorting is limited. Therefore, in recent years, roller-type, plate-type and belt-type equipment have been widely used in the market, and the number or weight of screening per unit area has increased significantly, and the accuracy and actual effect efficiency of fruit and vegetable sorting have been greatly improved. Recently, in the fruit and vegetable sorting industry, some manufacturers have introduced visual sorting technology, which realizes batch sorting of fruits and vegetables by sampling the output signal of the sensor through the microcomputer system, amplifying, A / D conversion, filtering and calculation. You can choose a high-precision sorting benchmark according to your needs, and use the microcomputer control system to intelligently operate the mechanical equipment, with flexible control operation, high sorting accuracy and extremely high work efficiency.
[0004] However, although the efficiency and accuracy of sorting have been improved, different fruits and vegetables and different customers and market demands are also different. It is impossible for one machine to meet the needs of various weight or size levels. This is because although the grading grid above meets the requirements of accurate grading, the guiding and dividing system below is fixed relative to a certain machine. In other words, no matter how finely the above is divided, a relatively fixed number of levels is basically formed below (for example, potatoes are divided into 6 levels at most, and the weight or size of each level cannot be adjusted). This limits the grading range of the equipment. The technical solution provided by the utility model is to solve this problem. Utility Model Content

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0039] Reference Figure 1 and 2, the utility model provides a fruit and vegetable sorting device.
[0040] The upper part of the fruit and vegetable sorting device is provided with a sorting assembly 17. Fruits and vegetables are placed on the sorting assembly 17, and the sorting assembly 17 can drive the fruits and vegetables to move in a horizontal direction. During the movement of the fruits and vegetables, the fruits and vegetables are sorted according to their size or weight. Specifically, when the fruits and vegetables move in the horizontal direction, they fall in the order of small to large size.
[0041] The material guiding assembly is arranged below the sorting assembly 17. The material guiding assembly includes a left flexible cloth 1, a right flexible cloth 2 and a plurality of intermediate flexible cloths 3. The plurality of intermediate flexible cloths 3 are arranged at intervals between the left flexible cloth 1 and the right flexible cloth 2. The intervals between the left flexible cloth 1 and the intermediate flexible cloths 3, the intervals between the two intermediate flexible cloths 3, and the intervals between the intermediate flexible cloths 3 and the right flexible cloth 2 all form guiding channels. The fruits and vegetables falling from the sorting assembly 17 will fall into the corresponding guiding channels. A platform or a discharging conveyor belt 18 is arranged below the guiding channel so that the fruits and vegetables can be discharged according to their sizes.
[0042] The specific structure of the guide material assembly is described below:
[0043] Reference Figure 3 , one end of the middle flexible cloth 3 is connected to the fixed shaft 4, and the other end is connected to the reeling shaft 5. The middle part of the middle flexible cloth 3 bypasses the grading shaft 6, and the grading shaft 6 is arranged at a position close to the sorting assembly 17. The fixed shaft 4 is arranged at the lower left side of the grading shaft 6, and the reeling shaft 5 is arranged at the lower right side of the grading shaft 6. This arrangement makes the middle flexible cloth 3 in an inverted V shape. Specifically, the left side of the middle flexible cloth 3 is between the fixed shaft 4 and the grading shaft 6, and its surface is an inclined surface inclined to the lower left; the right side of the middle flexible cloth 3 is between the grading shaft 6 and the reeling shaft 5, and its surface is an inclined surface inclined to the lower right.
[0044] Reference Figure 5 The upper end of the left flexible cloth 1 is connected to the upper left shaft 7, and the lower end of the left flexible cloth 1 is connected to the lower left shaft 8. The lower left shaft 8 is arranged on the lower right side of the upper left shaft 7 so that the surface of the left flexible cloth 1 is an inclined surface inclined to the lower right.
[0045] Reference Figure 6 The upper end of the right flexible cloth 2 is connected to the right upper shaft 9, and the lower end of the right flexible cloth 2 is connected to the right lower shaft 10. The right lower shaft 10 is arranged on the lower left side of the right upper shaft 9 so that the surface of the right flexible cloth 2 is an inclined surface inclined to the lower left.
[0046] Reference Figure 7 Each guide channel is composed of a slope located on the left side and tilted to the lower right, and a slope located on the right side and tilted to the lower left, and the two slopes are arranged opposite to each other. When the fruits and vegetables fall, they will fall along the slope onto the discharging conveyor belt 18.
[0047] Since the size range of fruits and vegetables that the guiding channel can receive is determined by the horizontal position of the grading shaft 6, in the present embodiment, the horizontal position of the grading shaft 6 can be adjusted, thereby adjusting the size range of fruits and vegetables that the guiding channel can receive. Specifically, the grading shaft 6 is slidably connected to the horizontal guide rail 11. More specifically, a slideway is provided on the horizontal guide rail 11, and both ends of the grading shaft 6 are slidably connected to the slideway so that the grading shaft 6 can move in the horizontal direction. And a locking structure is provided on the grading shaft 6, and the locking structure can fix the grading shaft 6 on the slideway. The locking structure is specifically a locking handwheel, which is connected to the grading shaft 6 by a thread. The locking handwheel can be rotated by the thread to press the horizontal guide rail 11 to fix the grading shaft 6; the locking handwheel can also rotate in the opposite direction to loosen the locking handwheel and the horizontal guide rail 11 so that the grading shaft 6 can move along the horizontal guide rail 11, see for details. Figure 2 .
[0048] When the horizontal position of the grading shaft 6 is adjusted, the length of the extended portion of the intermediate flexible cloth 3 will also change accordingly. Therefore, the reel 5 in this embodiment has a reeling and tensioning function so that the length of the deep portion of the intermediate flexible cloth 3 can be adjusted and maintained in a tensioned state. Specifically, a portion of the intermediate flexible cloth 3 is wound on the reel 5. Further, the reel 5 is provided with an outer cylinder, and the intermediate flexible cloth 3 is arranged in the gap between the reel 5 and the outer cylinder. The reel 5 is rotatably connected to the intermediate bracket 12. When the length of the extended portion of the intermediate flexible cloth 3 needs to be adjusted, the reel 5 can be rotated to reel or unroll the intermediate flexible cloth 3. Further, one end of the reel 5 extends out of the intermediate bracket 12 and is connected to a hand wheel so that the operator can rotate the reel 5 by the hand wheel. In addition, a ratchet 13 is provided on the reel 5, and a ratchet 14 is provided on the intermediate bracket 12. The ratchet 14 abuts against the ratchet 13 to prevent the reel 5 from rotating in the opposite direction. When the extended length of the middle flexible cloth 3 increases due to the adjustment of the horizontal position of the grading shaft 6, the middle flexible cloth 3 wound on the winding shaft 5 will unfold; when the extended length of the middle flexible cloth 3 decreases due to the adjustment of the horizontal position of the grading shaft 6, the winding shaft 5 is rotated to wind the middle flexible cloth 3 onto the winding shaft 5. The ratchet 13 and the pawl 14 can prevent the winding shaft 5 from rotating in the opposite direction to loosen the middle flexible cloth 3 during the winding process. Figure 3 and Figure 4 .
[0049] Since the length of the middle flexible cloth 3 is limited, the adjustment range of the horizontal position of the grading shaft 6 is also limited. Therefore, the horizontal position of the fixed shaft 4 and the horizontal position of the winding shaft 5 in this embodiment can also be adjusted to expand the adjustment range of the guide channel. Specifically, the fixed shaft 4 and the winding shaft 5 are both mounted on the middle bracket 12, and the middle bracket 12 is connected to the horizontal moving assembly so that the middle bracket 12 can move along the horizontal moving assembly. The horizontal moving assembly includes a gear 15 and a rack 16, and the gear 15 is rotatably connected to the middle bracket 12, and the gear 15 is meshed with the rack 16. The gear 15 can move in the horizontal direction of the rack 16, so that the middle bracket 12 and the fixed shaft 4 and the winding shaft 5 installed on the middle bracket 12 can move in the horizontal direction. Since the grading shaft 6, the fixed shaft 4 and the winding shaft 5 can all move horizontally, the middle flexible cloth 3 can also move accordingly, thereby adjusting the position of the guide channel and the size range of the fruits and vegetables received, see for details. Figure 2 and Figure 3 .
[0050] In addition, when the middle bracket 12 moves, the lengths of the left flexible cloth 1 and the right flexible cloth 2 also need to be adjusted to match the position of the middle flexible cloth 3 .
[0051] The specific structure of the left-end flexible cloth 1 will be described below.
[0052] Reference Figure 5 , the upper left shaft 7 is fixedly arranged, and the lower left shaft 8 is installed on the left bracket. The left bracket is also connected to the horizontal moving assembly. Specifically, the left bracket is rotatably connected to a gear 15, and the gear 15 is meshed with a rack 16 so that the left bracket can move along the gear 15. The lower left shaft 8 is rotatably connected to the left bracket, and part of the left end flexible cloth 1 is rolled up on the lower left shaft 8. When the left bracket moves along the horizontal moving assembly, the lower left shaft 8 also moves accordingly. By rotating the lower left shaft 8, the left end flexible cloth 1 rolled up on the lower left shaft 8 can be unfolded or the unfolded left end flexible cloth 1 can be rolled up on the lower left shaft 8. Furthermore, a ratchet 13 is arranged on the lower left shaft 8, and a pawl 14 is arranged on the left bracket. The pawl 14 is connected to the ratchet 13 to prevent the lower left shaft 8 from rotating in the opposite direction when the left end flexible cloth 1 is rolled up, thereby preventing the left end flexible cloth 1 from loosening and maintaining a tensioned state.
[0053] The specific structure of the right-end flexible cloth 2 will be described below.
[0054] Reference Figure 6, the upper right shaft 9 is fixedly arranged, and the lower right shaft 10 is installed on the right bracket. The right bracket is also connected to the horizontal moving assembly. Specifically, the right bracket is rotatably connected to a gear 15, and the gear 15 is meshed with a rack 16 so that the right bracket can move along the gear 15. The lower right shaft 10 is rotatably connected to the right bracket, and part of the right end flexible cloth 2 is rolled up on the lower right shaft 10. When the right bracket moves along the horizontal moving assembly, the lower right shaft 10 also moves accordingly. By rotating the lower right shaft 10, the right end flexible cloth 2 rolled up on the lower right shaft 10 can be unfolded or the unfolded right end flexible cloth 2 can be rolled up on the lower right shaft 10. Further, a ratchet 13 is arranged on the lower right shaft 10, and a pawl 14 is arranged on the right bracket. The pawl 14 is connected to the ratchet 13 to prevent the lower right shaft 10 from rotating in the opposite direction when the right end flexible cloth 2 is rolled up, thereby preventing the right end flexible cloth 2 from loosening and maintaining a tensioned state.
[0055] Figures 7 to 10 Four embodiments of the guide material assembly are shown, respectively showing the adjusted positions of the middle flexible cloth, the left end flexible cloth and the right end flexible cloth.
[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
