Description

Technical Field

[0001] This utility model relates to the field of dried fruit processing technology, specifically to a shell-cracking device for selling dried fruits. Background Technology

[0002] Longan, also known as dried longan, is a specialty fruit of southern my country. Rich in sugar and various vitamins, it is believed to have benefits such as nourishing the heart and spleen, replenishing blood, and calming the mind. Longan is processed into dried longan, which has long been considered a valuable tonic. However, most current dried longan sales rely on manual shelling, which is inconvenient for users to remove the shelled fruit, thus reducing work efficiency.

[0003] The prior art proposes a Chinese patent with publication number CN215224601U to solve the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: A shell-cracking device for selling dried longan includes a table, a horizontal plate at the top of the table, support rods bolted to both sides of the bottom of the horizontal plate, the bottom of the support rods being bolted to the table, a telescopic cylinder bolted to the top of the horizontal plate, a pressure plate bolted to the telescopic end of the telescopic cylinder, a gasket bolted to the bottom of the pressure plate, and a limit ring bolted to the top of the table. The device contains a placement basin. This invention lays the dried longan flat inside the basin, then activates a telescopic cylinder to move a pressure plate downwards. The pressure plate then moves a pad to tap the dried longan, effectively replacing manual tapping and improving work efficiency. The device uses a ball and a pole to remove the placement basin, allowing users to easily empty the tapped longan. However, existing technology requires manually removing the basin, emptying the dried fruit, and resetting it before starting the next tapping cycle, resulting in lower efficiency.

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides a shell-cracking device for selling dried fruits, including a processing table 1, a hopper 2, a collection box 3, and a reduction motor 10. The upper surface of the processing table 1 is rotatably connected to a crank 6 via a support frame 9. The rotating arm of the crank 6 is rotatably connected to a connecting rod 13 via a bushing. The bottom end of the connecting rod 13 is rotatably connected to a pressing rod 14. The outer wall of the pressing rod 14 is slidably connected to a limit plate 7, and the bottom end of the pressing rod 14 is fixedly connected to a pressure plate 5.

[0027] The outer wall of the pressure plate 5 is movably connected to a limiting pusher frame 4. Electric push rods 18 are fixedly connected to both sides of the limiting pusher frame 4 via mounting blocks. A rotating conveyor belt 15 for feeding is provided on the back of the limiting pusher frame 4. A first pulley 11 and a second pulley 12 are fixedly connected to the outer wall of the crank 6 near one end. The first pulley 11 is connected to a belt drive roller 17 via belt drive. The outer wall of the belt drive roller 17 is movably connected to the inner wall of one end of the rotating conveyor belt 15. The limiting pusher frame 4 is sufficient to completely push the dried fruits that have undergone shell-cracking into the collection box 3.

[0028] The output end of the geared motor 10 is movably connected to the outer wall of the second pulley 12 via a belt. The upper surface of the limiting plate 7 is provided with a guide sliding hole 8. The inner wall of the guide sliding hole 8 is slidably connected to the outer wall of the lower pressure rod 14. A partition plate is fixedly connected to the outer wall of the rotating conveyor belt 15.

[0029] A feeding chute is provided on the side of the limiting pusher frame 4 near the rotating conveyor belt 15. The fixed end of the electric push rod 18 is fixedly connected to the limiting frame 16 via a mounting plate. The inner wall of the limiting frame 16 is movably connected to both sides of the rotating conveyor belt 15, and the bottom surface of the hopper 2 is fixedly connected to the top of the limiting frame 16. The rotating conveyor belt 15, using a partition plate, can feed dried fruit into the limiting pusher frame 4 in small, multiple batches, reducing the accumulation of dried fruit in the limiting pusher frame 4 and preventing problems with shell removal.

[0030] Example 2

[0031] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the bottom surface of the support frame 9 is detachably fixed to the upper surface of the processing table 1 by bolts.

[0032] The collection box 3 is located on the side of the limiting pusher frame 4 away from the rotating conveyor belt 15.

[0033] The upper surface of the processing table 1 is provided with a conveyor belt placement groove 20 and a collection slot 19. The conveyor belt placement groove 20 is used to adapt to the installation of the rotating conveyor belt 15, and the inner wall of the collection slot 19 is engaged with the outer wall of the collection box 3.

[0034] Both ends of the limiting plate 7 are fixedly connected to the inner wall of the support frame 9.

[0035] The working principle of this shell-cracking device for selling dried fruits will be explained in detail below.

[0036] like Figure 1-5 As shown, when in use, the geared motor 10 and the electric push rod 18 are connected to an external controller. Then, the dried fruits that need to be shelled are put into the hopper 2. The bottom of the hopper 2 is located above the rotating conveyor belt 15. Some of the dried fruits will be put into the pressure plate 5 through the outlet at the bottom of the hopper 2. At this time, since the rotating conveyor belt 15 is stationary, the dried fruits will be blocked by the partition plate and will not be continuously put in.

[0037] Then, the geared motor 10 is started, which drives the crank 6 to rotate via the belt. The crank 6 then drives the pressing rod 14 to move up and down via the connecting rod 13. During the up and down movement, the pressing rod 14 moves up and down on the inner wall of the pressure plate 5 and the limiting pusher frame 4.

[0038] As the crank 6 rotates, it drives the first pulley 11 to rotate. The first pulley 11, in turn, drives the belt drive roller 17 to rotate via the belt. The belt drive roller 17 then drives the rotating conveyor belt 15 to rotate toward the position of the limiting pusher frame 4. At this time, the dried fruit on its surface is conveyed into the limiting pusher frame 4. Due to the obstruction of the partition plate, the amount of dried fruit particles put into the limiting pusher frame 4 each time is moderate, and no accumulation problem is caused.

[0039] During the process of conveying dried fruit by the rotating conveyor belt 15, the pressure plate 5 continuously applies pressure to the dried fruit inside the limiting pusher frame 4 to knock off the shells. After the rotating conveyor belt 15 has been in operation for a certain period of time, the reduction motor 10 stops. At this time, the electric push rod 18 starts, pushing the limiting pusher frame 4 to slide on the surface of the processing table 1, and transferring the dried fruit inside and the dried fruit that has completed the knocking off the shells. When the limiting pusher frame 4 moves above the collection box 3, all the dried fruit in the limiting pusher frame 4 will be transferred to the collection box 3. Then the electric push rod 18 pulls the limiting pusher frame 4 to reset. At this time, the reduction motor 10 starts again, and the subsequent knocking off of the dried fruit can be carried out.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
