Description

Technical Field

[0001] The present invention relates to the technical field of red date sorting, in particular to a feeding device of a red date sorting machine. Background Art

[0002] Red date sorting refers to the process of classifying and screening red dates to ensure that their quality and appearance meet market demand. Sorting criteria usually include the size, color, appearance, maturity, and presence of pests and diseases. This ensures that each grade of red dates meets the corresponding standards, thereby improving the overall quality of the product.

[0003] Before the red dates are sorted and processed, a loading device is required to load and transport the red dates so that they can enter a sorting device at a certain height. The existing loading device is not convenient for automatically controlling the amount of red dates when loading the red dates, resulting in too many or too few red dates entering the sorting machine, affecting the sorting effect of the red dates or reducing the sorting efficiency of the red dates, which is not conducive to improving the overall quality of the red dates. Therefore, we propose a loading device for the red dates sorting machine to solve the above-mentioned problems. Summary of the Invention

[0004] The object of the present invention is to provide a feeding device for a red date sorting machine, which has the function of controlling the feeding amount of red dates to achieve a good sorting effect.

[0005] The above-mentioned technical objectives of the present invention are achieved through the following technical solutions: a loading device of a red date sorting machine comprises a hopper, a conveying frame that is inclined and connected to the hopper, a support frame installed at the bottom of the hopper and the conveying frame, and a conveying assembly installed on the inner side of the conveying frame, wherein a plurality of partitions distributed at equal distances and fitted with the inner side of the conveying frame are installed on the outer side of the conveying assembly, and a red date gathering groove is formed between two adjacent partitions, and a vibrating assembly fitted with the inner side of the conveying assembly is installed on the inner side of the conveying frame, two mounting frames are installed on the conveying frame, a dust cleaning assembly is movably installed in the mounting frame, a driving assembly for driving the dust cleaning assembly to move is also installed in the mounting frame, and a rack plate engaged with the dust cleaning assembly is also installed in the mounting frame, and two rectangular strip holes are opened on the front and back sides of the inner wall of the conveying frame, a push plate is hinged on the dust cleaning assembly, and a connecting rod is hinged on the vibrating assembly and passes through the rectangular strip hole two and is hinged to the push plate.

[0006] By adopting the above technical solution, the red dates to be sorted are poured into the hopper, and then the conveying component is started, so that the multiple partitions on the outside of the conveying component rotate accordingly, so that the red dates to be sorted continuously fall into the red date gathering trough and then are sent into the sorting machine for sorting as the conveying component moves, completing the feeding process of the red dates. During the feeding process, the red date gathering trough with consistent specifications is used to realize the quantitative transportation of the red dates, avoiding too many or too few red dates entering the sorting machine, improving the sorting effect of the sorting machine, and thus helping to improve the overall quality of the red dates.

[0007] During the long feeding process, the dust and impurities attached to the red dates will adhere to the conveying assembly. The driving assembly starts and drives the cleaning assembly to move in the mounting frame. The cleaning assembly engages with the rack plate during the movement in the mounting frame, so that the cleaning assembly can also rotate in a circle during the horizontal movement. The horizontal movement of the cleaning assembly allows the cleaning assembly to move between two adjacent partitions to clean the red date gathering groove, and at the same time it can be retreated to the outside of the partition without affecting the movement of the partition on the conveying assembly. The circular rotation of the cleaning assembly can improve the cleaning effect of the red date gathering groove, realize automatic cleaning of the feeding device, and save manpower.

[0008] In the process of the driving component driving the cleaning component to move back and forth, the pushing plate is used to drive the connecting rod to deviate left and right, thereby driving the vibration component to knock the conveying component on the inner side of the conveying component, so that the red dates in the red date gathering trough can fall completely into the sorting machine, avoiding the red dates from being stuck in the red date gathering trough, and no manpower is required for clearing. At the same time, it can also remove some dust and impurities in the red date gathering trough, thereby improving the cleaning effect.

[0009] The present invention is further configured as follows: the conveying frame is also provided with a material baffle plate located above the hopper, the conveying frame is composed of two conveying side plates, the support frame is installed at the bottom of the conveying side plates, and two mounting frames 8 are respectively installed on the two conveying side plates.

[0010] By adopting the above technical solution, the material blocking plate can block the red dates in the red date gathering trough from the front and back sides to prevent the red dates from falling, and the two conveying side plates are used to block the red dates on the conveying component from the front and back sides. At the same time, the dust cleaning component can move between the two side plates to provide moving space for the dust removing component.

[0011] The present invention is further configured as follows: the hopper is a conical hopper, the conveying frame is arranged to pass through the left side of the inner wall of the hopper, and the bottom end of the right side of the inner wall of the hopper is tangent to the bottom end of the conveying frame.

[0012] By adopting the above technical solution, when the conveying component inside the conveying frame drives the partition to move, the red dates in the hopper can continuously fall into the red date gathering trough and then be sent into the sorting machine for sorting as the conveying component moves.

[0013] The present invention is further configured as follows: the conveying assembly includes two rotating wheels rotatably connected between the two conveying side plates, a conveying belt that transmits power to the two rotating wheels, and a conveying motor installed on one of the conveying side plates to drive one of the rotating wheels to rotate.

[0014] By adopting the above technical solution, the conveying motor starts one of the rotating wheels to rotate, and when one of the rotating wheels rotates, the other rotating wheel is driven to rotate through the conveying belt, so that the conveying belt rotates as a whole to load the red dates that fall into the red date gathering trough.

[0015] The present invention is further configured as follows: the partition is installed on the outside of the conveyor belt and fits between the two conveyor side plates, and the side of the partition away from the conveyor belt is flush with the edge of the conveyor side plate.

[0016] By adopting the above technical solution, the conveying side plates block the red dates in the red date gathering trough from the front and rear sides, preventing the red dates from falling during the loading process.

[0017] The present invention is further configured as follows: the dust cleaning assembly includes a sliding block slidably connected to the mounting frame, a connecting shaft rotatably connected between the two sliding blocks, a brush cylinder installed outside the connecting shaft, and a gear installed outside the connecting shaft and meshing with the rack plate.

[0018] By adopting the above technical solution, when the driving component starts to drive the sliding block to move back and forth in the mounting frame, the gear on the outside of the connecting shaft engages with the rack plate, so that the brush cylinder outside the connecting shaft can also rotate in a circle during the left and right movement. The horizontal movement of the brush cylinder allows the brush cylinder to move between two adjacent partitions to clean the red date gathering groove, and at the same time it can be retreated to the outside of the partition without affecting the movement of the partition on the conveyor belt. The circular rotation of the brush cylinder can improve the cleaning effect of the red date gathering groove, realize automatic dust cleaning of the feeding device, and save manpower.

[0019] The present invention is further configured as follows: the sliding block and the rack plate are arranged in a front-to-back staggered manner; and the diameter of the brush cylinder is less than or equal to the distance between two adjacent partitions.

During the feeding process, the red date gathering trough with consistent specifications is used to realize the quantitative transportation of the red dates, avoiding too many or too few red dates entering the sorting machine, improving the sorting effect of the sorting machine, and thus helping to improve the overall quality of the red dates.

[0028] 2. During the long feeding process, the dust and impurities attached to the red dates will adhere to the conveying assembly. The driving assembly starts to drive the cleaning assembly to move in the mounting frame.

[0037] See also Figure 1-4 The present invention provides a feeding device for a red date sorting machine, comprising a hopper 1, a conveying frame 2 arranged obliquely and connected to the hopper 1, a support frame 3 installed at the bottom of the hopper 1 and the conveying frame 2, and a conveying assembly 4 installed on the inner side of the conveying frame 2. The outer side of the conveying assembly 4 is provided with a plurality of partitions 5 distributed at equal distances and in contact with the inner side of the conveying frame 2, a red date gathering groove 6 is formed between two adjacent partitions 5, a rapping assembly 7 in contact with the inner side of the conveying assembly 4 is installed on the inner side of the conveying frame 2, and the conveying assembly 4 is provided with a rapping assembly 7 in contact with the inner side of the conveying assembly 4. Two mounting frames 8 are installed on the conveying frame 2, and a cleaning component 9 is movably installed in the mounting frame 8. A driving component 10 for driving the cleaning component 9 to move is also installed in the mounting frame 8. A rack plate 11 engaged with the cleaning component 9 is also installed in the mounting frame 8. Rectangular strip holes 12 are provided on the front and back sides of the inner wall of the conveying frame 2. A push plate 13 is hinged on the cleaning component 9, and a connecting rod 14 is hinged on the rapping component 7 and passes through the rectangular strip hole 12 and is hinged to the push plate 13.

[0038] The red dates to be sorted are poured into the hopper 1, and then the conveying component 4 is started, so that the multiple partitions 5 on the outside of the conveying component 4 rotate accordingly, so that the red dates to be sorted continuously fall into the red date gathering trough 6 and then are sent into the sorting machine for sorting as the conveying component 4 moves, completing the feeding process of the red dates. During the feeding process, the red date gathering trough 6 with consistent specifications is used to realize the quantitative transportation of the red dates, avoiding too many or too few red dates entering the sorting machine, improving the sorting effect of the sorting machine, and thus helping to improve the overall quality of the red dates.

[0039] The dust and impurities attached to the red dates will adhere to the conveying component 4. The driving component 10 is started to drive the cleaning component 9 to move in the mounting frame 8. The cleaning component 9 engages with the rack plate 11 during the movement in the mounting frame 8, so that the cleaning component 9 will also rotate in a circular motion during the horizontal movement. The horizontal movement of the cleaning component 9 allows the cleaning component 9 to move between two adjacent partitions 5 to clean the red date gathering groove 6, and at the same time it can be retreated to the outside of the partition 5 without affecting the movement of the partition 5 on the conveying component 4. The circular rotation of the cleaning component 9 can improve the cleaning effect of the red date gathering groove 6, realize automatic cleaning of the feeding device, and save manpower.

[0040] In the process of the driving component 10 driving the cleaning component 9 to move back and forth, the pushing plate 13 is used to drive the connecting rod 14 to deviate left and right, thereby driving the vibration component 7 to knock the conveying component 4 on the inner side of the conveying component 4, so that the red dates in the red date gathering groove 6 can fall completely into the sorting machine, avoiding the red dates from being stuck in the red date gathering groove 6, and no manpower is required for clearing. At the same time, it can also remove some dust and impurities in the red date gathering groove 6, thereby improving the cleaning effect.

[0041] The conveying frame 2 is also equipped with a baffle plate 15 located above the hopper 1. The conveying frame 2 is composed of two conveying side plates. The support frame 3 is installed at the bottom of the conveying side plate. The two mounting frames 8 are respectively installed on the two conveying side plates. The baffle plate 15 can block the red dates in the red date gathering groove 6 from the front and back sides to prevent the red dates from falling. The two conveying side plates are used to block the red dates on the conveying component 4 from the front and back sides. At the same time, the dust cleaning component 9 can move between the two side plates to provide moving space for the dust removing component 9.

[0042] The hopper 1 is a conical hopper, and the conveying frame 2 is arranged to pass through the left side of the inner wall of the hopper 1. The bottom end of the right side of the inner wall of the hopper 1 is tangent to the bottom end of the conveying frame 2, so that when the conveying component 4 inside the conveying frame 2 drives the partition 5 to move, the red dates in the hopper 1 can continuously fall into the red date gathering groove 6 and then be sent into the sorting machine for sorting as the conveying component 4 moves.

[0043] The conveying assembly 4 includes two rotating wheels 41 rotatably connected between the two conveying side plates, a conveying belt 42 that transmits power to the two rotating wheels 41, and a conveying motor 43 installed on one of the conveying side plates to drive one of the rotating wheels 41 to rotate. The conveying motor 43 starts one of the rotating wheels 41 to rotate. When one of the rotating wheels 41 rotates, the other rotating wheel 41 is driven to rotate through the conveying belt 42, so that the conveying belt 42 rotates as a whole to load the red dates that fall into the red date gathering groove 6.

[0044] The partition 5 is installed on the outside of the conveyor belt 42 and fits between the two conveyor side plates. The side of the partition 5 away from the conveyor belt 42 is flush with the edge of the conveyor side plate, so that the conveyor side plate blocks the red dates in the red date gathering groove 6 from the front and back sides to prevent the red dates from falling during the loading process.

[0045] The cleaning component 9 includes a sliding block 91 slidably connected to the mounting frame 8, a connecting shaft 92 rotatably connected between the two sliding blocks 91, a brush cylinder 93 installed on the outside of the connecting shaft 92, and a gear 94 installed on the outside of the connecting shaft 92 and meshing with the rack plate 11. When the driving component 10 starts to drive the sliding block 91 to move back and forth in the mounting frame 8, the gear 94 outside the connecting shaft 92 meshes with the rack plate 11, so that the brush cylinder 93 outside the connecting shaft 92 can also rotate in a circle during the left and right movement. The horizontal movement of the brush cylinder 93 allows the brush cylinder 93 to move between two adjacent partitions 5 to clean the red date gathering groove 6, and at the same time it can be retreated to the outside of the partition 5 without affecting the movement of the partition 5 on the conveyor belt 42. The circular rotation of the brush cylinder 93 can improve the cleaning effect of the red date gathering groove 6, realize automatic cleaning of the feeding device, and save manpower.

[0046] The sliding block 91 and the rack plate 11 are staggered in front and back, and the diameter of the brush cylinder 93 is less than or equal to the distance between two adjacent partitions 5, so that the brush cylinder 93 can extend between the two partitions 5 to clean the red date gathering groove 6.

[0047] The rapping assembly 7 includes a fixed shaft 71 installed on the inner side of the conveying frame 2, two swing rods 72 hinged on the outside of the fixed shaft 71, a rapping rod 73 connected to the top of the two swing rods 72 and in contact with the inner side of the conveying belt 42, a rubber sleeve 74 installed on the outside of the rapping rod 73, an arc-shaped hole 75 opened on the front and back sides of the inner wall of the conveying frame 2, and a limiting rod 76 installed on the opposite sides of the two swing rods 72 and extending into the arc-shaped hole 75. The connecting rod 14 is hinged on the bottom of the swing rod 72, and the push plate 13 is installed on the sliding block 91 and is located outside the mounting frame 8.

[0048] When the driving component 10 starts to drive the sliding block 91 to move, the pushing plate 13 moves left and right synchronously with the sliding block 91, thereby driving the connecting rod 14 to move left and right in the rectangular bar hole 12, so that the swing rod 72 swings left and right outside the fixed shaft 71 with the fixed shaft 71 as the center of the circle, and the vibrating rod 73 knocks the conveyor belt 42 on the inner side of the conveyor belt 42, so that the red dates in the red date gathering groove 6 can fall completely into the sorting machine, avoiding the red dates from being stuck in the red date gathering groove 6, without the need for manpower to dredge, and at the same time, it can also remove some dust and impurities in the red date gathering groove 6, thereby improving the cleaning effect. When the swing rod 72 swings left and right, the limit rod 76 moves in the arc hole 75, thereby improving the stability of the movement of the swing rod 72.

[0049] The driving assembly 10 includes a driving motor 101 installed in the mounting frame 8 and a screw rod 102 rotatably connected to the inner wall of the mounting frame 8 and connected to the output shaft of the driving motor 101. The sliding block 91 is threadedly connected to the outside of the screw rod 102. When the driving motor 101 is started, it drives the screw rod 102 to rotate. The sliding block 91 is slidably connected in the mounting frame 8 and threadedly connected to the outside of the screw rod 102, so that the sliding block 91 can move back and forth in the mounting frame 8, driving the cleaning assembly 9 to move for cleaning. At the same time, it can also make the vibration assembly 7 knock the conveyor belt 42 on the inner side of the conveyor belt 42 through the push plate 13 and the connecting rod 14 to prevent the red dates from getting stuck in the red date gathering groove 6.
