A fruit sorting and separating machine

Abstract

The application discloses a fruit sorting and separating machine, which comprises a screening box, a pushing cylinder, a brush cylinder and a rotating driving mechanism. The pushing cylinder is rotatably arranged in the screening box along an axis of the pushing cylinder and comprises a pushing shaft and a discharging shaft. The diameter of the discharging shaft is smaller than that of the pushing shaft. A spiral blade is arranged on the peripheral wall of the pushing shaft. The brush cylinder is rotatably arranged in the screening box along an axis of the brush cylinder. The upper end of the brush cylinder is close to one side of the pushing cylinder, and a screening space for supporting materials is formed between the pushing cylinder and the brush cylinder. The rotating driving mechanism is used for driving the pushing cylinder and the brush cylinder to rotate. The screening space formed by the pushing cylinder and the brush cylinder is used for receiving materials (shells and seeds). Through the reverse rotation of the pushing cylinder and the brush cylinder, a friction force acting towards two sides is applied to the materials in the screening space. Since the seeds are solid and have a large density, and the shells are hollow and have a small density, under the rotation of the pushing cylinder and the brush cylinder, the shells are driven to move towards two sides and separate from the screening space due to the friction force applied by the pushing cylinder and the brush cylinder, so that the separation of the shells and the seeds is realized.

[0035] Please refer to Figure 1 and Figure 2 In a preferred embodiment of the application, a fruit sorting and separating machine comprises a screening box 100, a propelling cylinder 200, a brush cylinder 300, a rotating driving mechanism 400 and a discharging hopper 500.

[0036] The push cylinder 200 is rotatably installed in the screening box 100 along its own axis. The push cylinder 200 includes a push shaft 210 and a discharge shaft 220. The discharge shaft 220 is coaxially connected to one end of the push shaft 210. The diameter of the discharge shaft 220 is smaller than that of the push shaft 210. The peripheral wall of the push shaft 210 is provided with a spiral blade 230.

[0037] The brush cylinder 300 is rotatably installed in the screening box 100 along its own axis, and the brush cylinder 300 is located on one side of the push cylinder 200. The upper end of the brush cylinder 300 near the push cylinder 200 forms a screening space 310 with the push cylinder 200 for supporting materials.

[0038] The rotary drive mechanism 400 drives the push cylinder 200 and brush cylinder 300 to rotate, and the push cylinder 200 and brush cylinder 300 rotate in opposite directions. The rotation of the push cylinder 200 and brush cylinder 300 both cause the material in the screening space 310 to tend to move upward at an angle. Figure 3 As shown, the push cylinder 200 and brush cylinder 300 are spaced apart on the left and right sides. The push cylinder 200 rotates counterclockwise, and the brush cylinder 300 rotates clockwise. It can be understood that seeds are usually solid with high density, while shells are hollow, arched structures with low density. Additionally, the outer surface of seeds is usually smooth, such as the smooth surface of camellia seeds, while the shells, after being peeled, have serrated edges and greater friction. Therefore, the shells in the screening space 310 are usually driven to the sides by the push cylinder 200 and brush cylinder 300, thus detaching the shells from the screening space 310 and achieving effective separation by utilizing the characteristics of the shells and seeds. The rotary drive mechanism 400 drives the push cylinder 200 to rotate, which in turn moves the material in the screening space 310 towards the feed shaft 220. This allows the material to be screened and separated while simultaneously moving towards the feed shaft 220, ensuring that the shells mixed with the seeds are continuously separated during the forward movement, guaranteeing the final separation and sorting effect. The discharge hopper 500 is located above the end of the push shaft 210 away from the discharge shaft 220, and is used to feed materials into the screening space 310. That is, one end of the push shaft 210 is located below the discharge hopper 500, and the other end is connected to the discharge shaft 220. The bottom of the discharge hopper 500 has a discharge port, which is located directly above the screening space 310.

[0039] The fruit sorting and separating machine provided by the application utilizes the screening space 310 formed by the pushing cylinder 200 and the brush cylinder 300 to receive the materials (shells and seeds), and by the reverse rotation of the pushing cylinder 200 and the brush cylinder 300, the materials in the screening space 310 are subjected to the friction force moving to both sides, and due to the solid and large density of the seeds and the hollow and small density of the shells, under the rotation of the pushing cylinder 200 and the brush cylinder 300, the shells are moved to both sides to separate from the screening space 310 due to the friction force applied by the pushing cylinder 200 and the brush cylinder 300, so as to realize the separation of the shells and the seeds, and the rotation driving mechanism 400 drives the rotation of the pushing cylinder 200 to drive the materials in the screening space 310 to move towards the discharge shaft 220, and the materials on the pushing shaft 210 are continuously subjected to the separation of the shells and the seeds, and when the materials are to be separated from the pushing shaft 210 and enter the area of the discharge shaft 220, the shells are separated at this time, and the seeds enter the area of the discharge shaft 220, and due to the smaller diameter of the discharge shaft 220 than the pushing shaft 210, a gap for the discharge of the seeds is formed, and the seeds directly fall from the side of the discharge shaft 220, so as to realize the discharge of the seeds. In addition, the peripheral wall of the discharge shaft 220 is a cylindrical surface and continuously rotates, and the seeds are not accumulated on the discharge shaft 220.

[0040] During the shelling process, some fruits that are not successfully shelled may still be mixed in, so that during the sorting, the fruits that are not successfully shelled are easy to be discharged together with the seeds. In order to further improve the separation and sorting function, with reference to Figure 4 In some embodiments of the application, the pushing shaft 210 comprises a feeding section 211, a shell screening section 212 and a fruit screening section 213 arranged in sequence in the direction towards the discharge shaft 220, the feeding section 211 is used to receive the materials falling from the discharge hopper 500, that is, the section of the screening space 310 corresponding to the feeding section 211 is used to receive the materials falling from the discharge hopper 500; the shell screening section 212 and the brush cylinder 300 are rotated to separate the shells out of the screening space 310; the fruit screening section 213 and the brush cylinder 300 are rotated to separate the fruits that are not shelled out of the screening space 310, so as to realize the successive separation of the materials.

[0041] With reference to Figure 4 In further embodiments of the application, the brush cylinder 300 is surrounded by a brush 370, and when the brush cylinder 300 rotates at high speed, the outer periphery of the brush 370 forms a dense friction surface 371 for increasing the friction force of the materials in the screening space 310. However, when the brush cylinder 300 acts on the materials through the brush 370, the brush 370 can embed into the bottom of the materials to push up the materials, not only relying on the friction force, and in addition, the fine and broken residues can be brushed up and separated out together with the shells. It can be understood that the peripheral wall of the pushing cylinder 200 is not a smooth surface, but a rough surface, which can provide friction force to the materials, so as to realize the separation of the materials.

[0042] Of course, in other embodiments, the brush cylinder 300 can also be a cylindrical surface, and the rotation of the cylindrical surface provides friction to the material, but the separation effect on fine slag is poor, and it is not as good as the effect of setting the brush 370.

[0043] Referring to Figure 4 In further embodiments of the application, the pitch of the helical blades 230 of the shell screening section 212 is greater than the pitch of the helical blades 230 of the fruit screening section 213, and the pitch of the helical blades 230 of the fruit screening section 213 is smaller than the fruit diameter of the unshelled fruit entering from the material hopper 500, and the diameter of the shelled seeds 202 is smaller than the pitch of the helical blades 230 of the fruit screening section 213 and can be embedded in the pitch of the helical blades 230. As shown in Figure 6 When the unshelled fruit 201 enters the fruit screening section 213, the unshelled fruit 201 cannot be stuck in the pitch of the helical blades 230, but is lifted by the helical blades 230, and the unshelled fruit contacts the outer peripheral wall of the helical blades 230. Compared with the contact of the seeds 202 with the peripheral wall of the advancing shaft 210, the unshelled fruit 201 is farther away from the axis of the advancing shaft 210 and the contact position with the helical blades 230 is higher, and the friction force is more distributed in the horizontal direction, so the unshelled fruit 201 receives a greater friction force than the seeds 202, and in addition, the unshelled fruit 201 is lifted by the helical blades 230, so that there is a large gap between the unshelled fruit 201 and the peripheral wall of the fruit screening section 213, thereby facilitating the insertion of the brush below the unshelled fruit 201 and rotating upward to push the unshelled fruit 201, and the unshelled fruit 201 is better driven by the fruit screening section 213 to be thrown out of the screening space 310 from the side, so that the unshelled fruit 201 in the material can also be separated, thereby avoiding mixing into the seed material and affecting subsequent processing. It can be understood that in order to improve the screening effect, the outer peripheral wall of the helical blades 230 is a friction surface or is provided with small sawteeth, thereby increasing the friction force with the unshelled fruit 201.

[0044] Referring to Figure 3 In further embodiments of the application, the screening box 100 is provided below the shell screening section 212 with a shell discharge guide plate 130, the shell discharge guide plate 130 is provided with two and is in a converging shape downward, thereby converging the shells separated from the two sides of the advancing cylinder 200 and the brush cylinder 300, and a shell collection box can be provided below the shell discharge guide plate 130, thereby realizing the collection of the shell material.

[0045] Referring to Figures 1 to 3 In further embodiments of the application, the screening box 100 is provided below the fruit screening section 213 with a fruit discharge inclined plate 140, the fruit discharge inclined plate 140 extends to the side wall of the screening box 100 and forms a fruit discharge opening 141, thereby guiding the unshelled fruit 201 out of the screening box 100 for easy collection.

[0046] In a further embodiment of the present invention, the propulsion cylinder 200 can adjust its axial position along a first preset direction, and the brush cylinder 300 can adjust its axial position along a second preset direction, thereby realizing position adjustment and facilitating equipment debugging; specifically, the first preset direction is perpendicular to the second preset direction, thereby realizing multi-dimensional position adjustment.

[0047] Reference Figure 5 In a further embodiment of the present invention, the first preset direction is the height direction, and the second preset direction is the radial horizontal direction of the brush cylinder 300. The second preset direction is... Figure 5 The left and right directions, the up and down adjustment of the push cylinder 200, and the left and right adjustment of the brush cylinder 300 can all adjust the contact position between the material and the brush cylinder 300 and the push cylinder 200. When the contact position between the material and the push cylinder 200 is closer to the top of the push cylinder 200, the shells and unshelled fruits 201 are more easily separated. However, if it is too close to the top of the push cylinder 200, the seeds may be thrown out. Therefore, the position needs to be adjusted to ensure the separation effect. For example, when the push cylinder 200 is adjusted downwards, the contact position between the material and the push cylinder 200 is closer to the top of the push cylinder 200, making it easier to separate the material out of the screening space 310.

[0048] Specifically, the push cylinder 200 has first journals 240 extending from the screening box 100 at both ends. A first bearing seat 250 is fitted on the first journal 240. A first connecting lug 260 is provided on the periphery of the first bearing seat 250. A bearing is provided between the first journal 240 and the first bearing seat 250 to reduce rotational friction. The first connecting lug 260 has a first connecting hole 270. The periphery of the screening box 100 has a first elongated hole 110 whose length direction is the height direction. The first connecting hole 270 is aligned with the first elongated hole 110 and is fixed by fasteners. The first connecting hole 270 can be aligned with different height positions of the first elongated hole 110 to realize the position adjustment of the push cylinder 200 in the height direction. The brush cylinder 300 has second journals 320 extending from the screening box 100 at both ends. A second bearing seat 330 is fitted on the second journal 320. A bearing is provided between the second journal 320 and the second bearing seat 330 to reduce rotational friction. The second bearing housing 330 has a second connecting lug 340 on its periphery, and the second connecting lug 340 has a second connecting hole 350. The screening box 100 has a second elongated hole 120 with a horizontal length direction on its peripheral wall. The second connecting hole 350 is aligned with the second elongated hole 120 and fixed by fasteners. The second connecting hole 350 can be aligned with different horizontal positions of the second elongated hole 120 to achieve horizontal position adjustment of the brush cylinder 300. The fasteners can be bolts and nuts. The first bearing housing 250 and the second bearing housing 330 are used to install the push cylinder 200 and the brush cylinder 300, and the design of the first elongated hole 110 and the second elongated hole 120 allows for position adjustment of the push cylinder 200 and the brush cylinder 300, thereby achieving equipment adjustment and bringing the equipment to a suitable state.

[0049] With reference to Figure 5 The first and second shaft necks 240 and 320 on the same side extend out of the first and second bearing seats 250 and 330 respectively and are connected with the first and second transmission wheels 280 and 360 respectively, and the rotary output shaft of the rotary driving mechanism 400 is connected with the first and second transmission wheels 280 and 360 through a transmission structure. The first and second transmission wheels 280 and 360 can be sprockets, and the transmission structure can be a chain, so as to realize the rotary driving of the pushing barrel 200 and the brush barrel 300. The rotary driving mechanism 400 can be a rotary motor.

[0051] The above only the preferred embodiments of the present application, and is not intended to limit the present application, for those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
