[0007] Preferably, the pushing assembly includes: a connecting frame assembled on the outside of one side of the sorting cylinder, a communicating opening being provided on the outer wall of one side of the sorting cylinder, a limiting block being provided at the top of the connecting frame, and a first scraper being fixedly connected to the outer wall of the limiting block, and a second scraper being fixedly connected to the outer wall of the connecting frame, the second scraper passing through the communicating opening and extending into the sorting cylinder, the first scraper and the second scraper being located in two sorting frames respectively, and a telescopic groove being provided at the bottom of both the first scraper and the second scraper, with a scraper inserted into the bottom of the telescopic groove, and a plurality of multi-strand helical springs connecting the telescopic groove and the scraper.

[0008] Preferably, the bottom side of the scraper is arc-shaped, a pair of connecting rods are welded to the bottom of the limiting block, a pair of connecting holes are opened on the top of the connecting frame, and the bottom end of the connecting rod is inserted into the connecting hole. A threaded rod is installed on the connecting frame by threads, and the bottom end of the threaded rod is connected to the connecting frame by threads. A gasket is fitted on the bottom end of the threaded rod, and a handle is fitted on one side of the threaded rod. A rubber pad is glued to the bottom of the connecting frame, and the rubber pad is designed to fit snugly against the bottom of the sorting cylinder.

[0009] Preferably, a movable frame is fixedly connected to the bottom of the motor, a slide rail is screwed to the bottom end face of the sorting cylinder, and a magnet is slidably installed on the slide rail. The top of the movable frame is screwed to the bottom of the magnet, and a handle is fixedly connected to the outer wall of the movable frame.

[0010] Preferably, the slide rail is made of ferritic stainless steel and is magnetically connected to the magnet.

[0011] Preferably, a support plate is welded to one bottom end of the support rod, a bracket is fixedly connected to the bottom of the sorting cylinder, and an electric push rod is screwed to the top of the bracket. The telescopic end of the electric push rod is screwed to the bottom of the support plate.

[0012] Preferably, a conveyor frame is assembled on the other side of the sorting cylinder, and a pair of reinforcing frames are welded to the bottom of the conveyor frame. The other end of the reinforcing frame is screwed to the sorting cylinder, and a controller is assembled on the outer wall of the sorting cylinder.

[0013] Compared with related technologies, the multi-stage sorting conveyor for walnut processing provided by this utility model has the following beneficial effects:

[0014] 1. By pouring walnuts into the sorting cylinder, the sieve holes on the sorting frame can sort them according to their size. The motor drives the gears, and the gears and grooves work together to rotate the sorting frame and the collection frame through the sleeve, thus moving the walnuts continuously. When the size of the walnut is smaller than the sieve hole, it will fall into the bottom sorting frame and undergo secondary sorting. After sorting, the remaining walnuts will be stored in the collection frame. The pushing component can squeeze the walnut pits stuck in the sieve hole, allowing the walnuts to pass through the sieve hole and avoiding clogging the sieve hole, which would affect the sorting effect of the equipment.

[0015] 2. The first and second scrapers can block the walnuts. As the sorting frame moves, walnuts of suitable size will pass through the screen holes. If there are walnuts of suitable size but stuck in the screen holes due to irregular shell shape, they will pass through the screen holes under the pressure of the scrapers. When a walnut is stuck in the screen hole and the scraper's squeezing force cannot push it out, the scraper will retract into the telescopic groove to prevent the walnut from blocking the scraper and affecting the rotation of the sorting frame. When the stuck walnut passes the position of the scraper, the tension of the multi-strand spiral springs can make the scraper re-adhere to the inner wall of the sorting frame. Repeatedly squeezing the walnuts in the screen holes can make the walnuts fall off, ensuring the normal sorting of the equipment.

[0016] 3. By pulling the handle, the position of the movable frame on the slide rail can be moved, thereby separating the gear from the tooth groove. The position of the movable frame can be fixed by the magnetic attraction between the slide rail and the magnet. The support plate can be moved up by the electric push rod, which can move the sorting frame and the collection frame out of the sorting cylinder for easy removal of the sorted walnuts. When the electric push rod moves the sorting frame and the collection frame back to the sorting cylinder, the limiting plate can restrict the position of the sleeve. The inner contour of the conveyor frame is arc-shaped to prevent the walnuts from rolling off the sides of the conveyor frame during the conveying process. Attached Figure Description

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Example 1

[0027] A preferred embodiment of the multi-stage sorting conveyor for walnut processing provided by this utility model is as follows: Figures 1 to 6 As shown: A multi-stage sorting conveyor for walnut processing includes: a sorting cylinder 1; an movable opening 2 at the center of the bottom of the sorting cylinder 1; a support rod 3 inside the sorting cylinder 1, and a sleeve 4 sleeved on the support rod 3; two sorting frames 5 longitudinally welded to the outer wall of the sleeve 4; a plurality of sieve holes 6 equidistantly opened at the bottom of the sorting frames 5; a collection frame 7 welded to the outer wall of the sleeve 4, and the collection frame 7 located below the bottom of the two sorting frames 5; a pushing component 8 provided on one side of the sorting cylinder 1 to prevent walnuts from blocking the sieve holes 6; a toothed groove 9 opened at the bottom of the sleeve 4; a motor 10 provided below the bottom of the sorting cylinder 1; and a gear 11 fixed at the output end of the motor 10, the gear 11 meshing with the toothed groove 9.

[0028] In this embodiment, walnuts are poured into the sorting cylinder 1. The sieve holes 6 on the sorting frame 5 can be used to sort the walnuts according to their size. The motor 10 drives the gear 11. With the cooperation of the gear 11 and the tooth groove 9, the sleeve 4 can drive the sorting frame 5 and the collection frame 7 to rotate, thereby moving the walnuts continuously. When the size of the walnut is smaller than the sieve hole 6, it will fall into the bottom sorting frame 5 and be sorted again. After the sorting is completed, the remaining walnuts will be stored in the collection frame 7. The pushing component 8 can squeeze the walnut pits stuck in the sieve hole 6 so that the walnuts can pass through the sieve hole 6 and avoid clogging the sieve hole 6 and affecting the sorting.

[0029] In a further preferred embodiment of this utility model, the sizes of the sieve holes 6 on the two sorting frames 5 are different, and the size of the sieve hole 6 in the top sorting frame 5 is larger than the size of the sieve hole 6 in the bottom sorting frame 5.

[0030] In this embodiment, sieve holes 6 of different sizes can separate walnuts of different sizes.

[0031] In a further preferred embodiment of this utility model, the pushing component 8 includes: a connecting frame 801 assembled on the outside of one side of the sorting cylinder 1; a connecting port 802 is provided on the outer wall of one side of the sorting cylinder 1; a limiting block 803 is provided on the top of the connecting frame 801; a first scraper 804 is fixedly connected to the outer wall of the limiting block 803; a second scraper 805 is fixedly connected to the outer wall of the connecting frame 801; the second scraper 805 passes through the connecting port 802 and extends into the sorting cylinder 1; the first scraper 804 and the second scraper 805 are respectively located in two sorting frames 5; a telescopic groove 806 is provided at the bottom of both the first scraper 804 and the second scraper 805; a scraper 807 is inserted into the bottom of the telescopic groove 806; and a plurality of multi-strand helical springs 808 are connected between the telescopic groove 806 and the scraper 807.

[0032] In this embodiment, the first scraper 804 and the second scraper 805 can block the walnuts. As the sorting frame 5 moves, walnuts of suitable size will pass through the sieve hole 6. If there are walnuts of suitable size but stuck in the sieve hole 6 due to irregular shell shape, they will pass through the sieve hole 6 under the pressure of the scraper 807. When the walnut is stuck in the sieve hole 6 and the squeezing force of the scraper 807 cannot push the walnut off, the scraper 807 will retract into the telescopic groove 806 to prevent the walnut from blocking the scraper 807 and affecting the rotation of the sorting frame 5. When the stuck walnut passes the position of the scraper 807, the tension of the multi-strand helical spring 808 can make the scraper 807 re-adhere to the inner wall of the sorting frame 5. Repeatedly squeezing the walnut in the sieve hole 6 can make the walnut fall off.

[0033] In a further preferred embodiment of this utility model, the bottom side of the scraper 807 is arc-shaped, a pair of connecting rods 809 are welded to the bottom of the limiting block 803, a pair of connecting holes 810 are opened on the top of the connecting frame 801, and one bottom end of the connecting rod 809 is inserted into the connecting hole 810. A threaded rod 811 is installed on the connecting frame 801 by threads, and one bottom end of the threaded rod 811 is connected to the connecting frame 801 by threads. A gasket 812 is sleeved on one bottom end of the threaded rod 811, and a handle 813 is assembled on one side of the threaded rod 811. A rubber pad 814 is glued to the bottom of the connecting frame 801, and the rubber pad 814 is designed to fit snugly against the bottom of the sorting cylinder 1.

[0034] In this embodiment, the arc-shaped scraper 807 can easily squeeze the walnuts, and at the same time, it makes the retraction of the scraper 807 easier. By inserting the connecting rod 809 into the connecting hole 810, the limiting block 803 and the connecting frame 801 can be connected. The threaded rod 811 can be connected to the connecting frame 801 by rotating the handle 813. Under the clamping of the connecting frame 801 and the limiting block 803, the connecting frame 801 can be fixed on the sorting cylinder 1. The rubber pad 814 can increase the friction between the connecting frame 801 and the sorting cylinder 1.
