Description

Technical Field

[0001] The present invention belongs to the technical field of primary processing of agricultural products, and particularly relates to a primary processing machine for agricultural products, namely a wild jujube stone removing machine. Background Art

[0002] In recent years, traditional Chinese medicine has been attracting more and more attention from people. As a commonly used traditional Chinese medicine, wild jujube seeds are in increasing market demand. Wild jujube seeds are obtained by peeling off the pulp and the shell of mature wild jujubes.

[0003] At present, the mechanical equipment for producing wild jujube seeds on the market all discard the pulp of wild jujubes as garbage, and there is no processing equipment that can effectively collect the pulp of wild jujubes. The reason is that wild jujubes contain a relatively large amount of pectin. During the process of separating the fruit stones from the pulp, the pulp and the fruit stones will stick together, making it difficult to completely separate the wild jujube stones, and the processing machinery will also be stuck by the fruit glue and unable to operate normally.

[0004] Therefore, the current wild jujube stone removing machines on the market all adopt the method of flushing with water. During the processing, a large amount of water is used to wash away the peeled wild jujube pulp, leaving only the wild jujube stones. Processing one ton of wild jujubes requires consuming as much as 3 - 5 tons of water. This not only wastes a large amount of precious water resources, but also generates a large amount of sewage, and causes the wild jujube pulp to lose its recycling value because it is mixed with too much water and can only be discarded as garbage. The discarded wild jujube pulp will start to ferment and rot within a few hours, producing a stench and causing serious pollution. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a wild jujube stone removing machine, which does not require adding water during the process of separating the pulp and the fruit stones of wild jujubes, can fully separate the pulp and the fruit stones of wild jujubes, ensure that the fruit stones are clean without adhering pulp; the separated pulp is also clean and pollution-free, can be collected and fully utilized as raw materials for food and health products; at the same time, a large amount of water resources are saved, and the pollution generated during the processing of wild jujubes is completely solved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0054] In order to make the purpose, technical solutions and advantages of the present application clearer, the following describes and explains the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Based on the embodiments provided in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0055] As Figures 1-5 shown, this embodiment provides a wild jujube stone-removing machine, which includes a bracket 160, a stone-removing device and a clean-stone device installed on the bracket 160. Among them, the stone-removing device is connected in series upstream of the clean-stone device. The stone-removing device is used to realize the preliminary separation of the wild jujube pulp and the fruit stone, and collect the separated pulp; the clean-stone device is used to remove the residual pulp and pericarp on the fruit stone.

[0056] The stone-removing device includes a feed inlet 110, a sieve cage 122, a striking device, an outer cover 121, a pulp discharge port 130, a fruit stone discharge channel 140 and a first power device.

[0057] The feed inlet 110 is connected to the sieve cage 122 and is used to feed wild jujubes into the sieve cage 122. The pulp discharge port 130 is arranged below the sieve cage 122 and is connected to the sieve cage 122, and is used to discharge the wild jujube pulp separated by the sieve cage 122. It can be understood that the pulp discharge port 130 is connected with a pulp collection device (not shown in the figure). The fruit stone discharge channel 140 is configured such that one end close to the sieve cage 122 is connected to the sieve cage 122, and at the same time, the other end of the fruit stone discharge channel 140 far from the sieve cage 122 is connected to the clean-stone device, so as to be able to transport the wild jujube stones that have undergone meat-stone separation treatment in the sieve cage 122 to the clean-stone device. It should be noted that at this time, the wild jujube stones transported to the clean-stone device still have residual pulp and pericarp, which need to be further processed by the clean-stone device.

[0058] The first power device can provide power for the stone-removing device so that the meat-stone separation of wild jujubes can be realized in the stone-removing device.

[0059] The bracket 160 is configured as a support for the stone-removing device to realize the stability of the stone-removing device.

[0060] The sieve cage 122 is fixedly installed inside the outer cover 121, and both ends of it are configured to be closed by the outer cover 121. The sieve cage 122 is configured as a cylindrical hollow tube made of a metal perforated plate or a metal mesh, and the material is a metal material (such as 304 stainless steel); the sieve cage 122 is evenly and densely distributed with holes of the same shape, so that the sieve cage 122 forms a hollow state, so that the wild jujube pulp can be discharged from the sieve cage 122 while isolating the wild jujube stones in the sieve cage 122. A square (or other shape) hole is opened on the side wall of the sieve cage 122 near the clean-stone device end, and the outside of the hole is connected to the fruit stone discharge channel 140, and the size is matched with the cross-sectional size of the fruit stone discharge channel 140. The fruit stone discharge channel 140 passes through the outer cover 121 and leads to the inside of the clean-stone device.

[0061] Preferably, the wall thickness of the screening cage 122 is 0.3 - 2 mm, the diameter is 30 - 75 cm, and the length is 60 - 120 cm. The shape of the holes is circular or other regular or irregular shapes, the hole diameter is 2 - 5 mm, which can ensure that the wild jujube flesh is discharged from the screening cage 122 while isolating the wild jujube pits in the screening cage 122. The net distance between the holes is 1 - 5 mm. The size of the hole opening is 10 - 30 cm in length and 10 - 30 cm in width, and the length dimension of the pit discharge channel 140 is 20 - 60 cm.

[0062] In this embodiment, the pit discharge channel 140 is configured to incline downward at a certain angle, the inclination angle is 5 - 30°, and the end close to the pitting device is higher than the end close to the pit cleaning device; through the setting of the inclination angle, it can ensure that the pit discharge channel 140 conveys the wild jujube pits to the pit cleaning device more smoothly and quickly, and at the same time avoids the potential problem that the pit discharge channel 140 may be blocked by the wild jujube pits.

[0063] In this embodiment, the outer cover 121 is configured in a cuboid shape and wraps and fixes the screening cage 122 inside it. There are gaps between the wall plates on the front, back and top sides of the outer cover 121 and the screening cage 122, and the distance at the smallest gap is 2 - 10 cm. The left and right side walls of the outer cover 121 are fixedly connected to the screening cage 122. An inlet hole is provided on the right side wall of the outer cover 121, the diameter of the inlet hole is 10 - 30 cm, the inside of the inlet hole is communicated with the inside of the screening cage 122, and an inlet port 110 is installed outside the inlet hole. The lower bottom surface of the outer cover 121 is open and is communicated with the pulp discharge port 130 located below the outer cover 121, so as to discharge the pulp discharged from the mesh holes of the screening cage 122 into the pulp discharge port 130 below the outer cover 121 and finally send it to the pulp collection device.

[0064] In this embodiment, the hitting device is located inside the screening cage 122 and includes a rotating shaft 310 and a side cantilever 320. The rotating shaft 310 is coaxially arranged with the screening cage 122, and its two ends are respectively installed on the left side wall and the right side wall of the outer cover 121 through a pair of first bearings 400. The side cantilevers 320 are evenly arranged on the rotating shaft 310 at an interval of 5 - 20 cm, and the side cantilevers 320 are perpendicular to the rotating shaft 310. Both the rotating shaft 310 and the side cantilevers 320 are configured of metal materials (such as 304 stainless steel). The diameter of the rotating shaft 310 is 3 - 10 cm, the diameter of the side cantilevers 320 is 1.5 - 3 cm, and the distance between the end of the side cantilever 320 close to the screening cage 122 and the screening cage 122 is 0.5 - 2 cm.

[0065] In this embodiment, the first power device includes a first motor 151, a pulley 152 and a first belt 153. The pulley 152 is connected to the motor 151 through the first belt 153. The pulley 152 is installed at one end of the rotating shaft 310 close to the first motor 151. After the power is turned on, the first motor 151 drives the first belt 153 to move. Further, the first belt 153 can drive the rotating shaft 310 to rotate by itself through the pulley 152. During the rotation of the rotating shaft 310, the side cantilever 320 rotates accordingly and can strike the wild jujubes in the sieve cage 122 at the same time. By setting a certain rotating speed of the rotating shaft, it is ensured that during the process of the cantilever 320 striking the wild jujubes, the flesh of the wild jujubes is separated from the wild jujube pits, and the flesh of the wild jujubes can be discharged through the holes on the sieve cage 122, and the integrity of the wild jujube pits is ensured and they are not broken by the strike. The rotating speed of the rotating shaft 310 can be set to 500 - 1000 revolutions per minute.

[0066] In this embodiment, the pulp discharge port 130 is located below the lower bottom surface of the outer cover 121 and is configured as a stainless - steel inclined plane with both sides closed. The upper top surface of the pulp discharge port 130 is open and communicates with the lower bottom surface of the outer cover 121, so as to be able to receive the pulp discharged from the sieve cage 122 and then convey it to the pulp collection device. The pulp discharge port 130 extends 10 - 20 cm outside the support 160, which is more convenient for collecting the pulp.

[0067] Thus, the working process of wild jujube pit removal can be understood as follows: Untreated wild jujubes are added through the feeding port 110. The wild jujubes enter the sieve cage 122. The first motor 151 drives the first belt 153 to move. Further, the first belt 153 can drive the rotating shaft 310 to rotate by itself through the pulley 152. During the rotation of the rotating shaft 310, the side cantilever 320 rotates accordingly and can strike the wild jujubes in the sieve cage 122. Under the continuous strike of the cantilever 320, the flesh of the wild jujubes is separated from the pits. On the one hand, the flesh is discharged from the holes on the sieve cage 122 to the outside of the sieve cage 122 and flows down to the stainless - steel inclined plane of the pulp discharge port 130, and finally is sent to the pulp collection device through the pulp discharge port 130. On the other hand, the pits separated from the flesh are conveyed to the pit - cleaning device through the pit discharge channel 140. At this time, there is still flesh and peel remaining on the wild jujube pits conveyed to the pit - cleaning device, and the pit - cleaning device needs to further process them.

[0068] The pit - cleaning device includes a mesh cage 211, a longitudinal beam 212, a brush roller 213 and a second power device. The support 160 is configured as a support for the pit - cleaning device. The mesh cage 211 and the second power device 230 are fixedly connected to the support 160 to achieve the stability of the pit - cleaning device.

[0069] The cage 211 is configured in the shape of a hollow cylinder with a diameter of 0.5 to 1 m and a length of 2 to 6 m. One end close to the pitting device is the nuclear inlet end and is connected to the fruit pit discharge channel 140, so as to be able to receive the wild jujube pits processed by the pitting device; the end far from the pitting device is the nuclear outlet end, which is used to discharge the cleaned wild jujube pits. The cage 211 is made of a wire mesh, and the material of the wire mesh is a metal material (such as 304 stainless steel). The diameter of the wire making the wire mesh is set to 0.5 to 2 mm to reduce the weight of the wire mesh on the premise of ensuring that the wire mesh has sufficient stiffness. The aperture of the mesh holes of the wire mesh is configured to be 3 to 5 mm, which can ensure that residual substances such as pulp are discharged from the cage 211 while isolating the wild jujube pits in the cage 211. The cage 211 is arranged obliquely with an inclination angle of 5 to 30°, and the nuclear inlet end is higher than the nuclear outlet end. Through the setting of the inclination angle, the wild jujube pits can move towards the nuclear outlet end of the cage 211. On the one hand, it is convenient for the collection of wild jujube pits, and on the other hand, it prevents the wild jujube pits from accumulating at the connection where the cage 211 is connected to the discharge port 140.

[0070] The longitudinal beam 212 runs through the inside of the cage 211, and the two end portions of the longitudinal beam 212 extending out of the cage 211 are respectively fixedly installed on the bracket 160. The longitudinal beam 212 is parallel to the center line of the cage 211 and is located at a position close to the bottom of the side of the cage 211, 5 to 15 cm away from the bottom of the side of the cage 212.

[0071] The brush roller 213 is installed on the longitudinal beam 212 through a cantilever, and the axis of the brush roller 213 is parallel to the center line of the cage 211; the diameter of the brush roller 213 is 10 to 30 cm, and the length of the plastic fibers is 3 to 10 cm; the brush roller 213 is in close contact with the inner wall of the cage 211, so that the brush roller 213 can roll synchronously when the cage 211 rotates. Moreover, the brush fibers extend outwards by 0.5 to 3 mm through the mesh holes of the cage 211, so that the pulp and peel that are brushed off can be pushed outside the cage 211 through the mesh holes on the cage 211, preventing the pulp and peel from blocking the mesh holes of the cage 211.

[0072] In this embodiment, the second power device 230 includes a second motor 231, a speed reducer 232, a second belt 233, a transmission shaft 234, a driving gear 235, a driven gear 236, a second bearing 237, a cage hoop 238, and a support roller 239. The second motor 231 is installed at the lower part of the bracket 160 and is set at an inclined angle that is consistent with the cage 211. The speed reducer 232 is installed at the upper part of the bracket 160 and is set at an inclined angle that is consistent with the cage 211. The speed reducer 232 is connected to the second motor 231 through the second belt 233 for transmission. A transmission shaft 234 is arranged below the outer side of the lower side surface of the cage 211, and the axis of the transmission shaft 234 is parallel to the center line of the cage 211. Both ends of the transmission shaft 234 are rotatably installed on the bracket 160 through the second bearings 237. A driving gear 235 is installed at each end of the transmission shaft 234, the driven gear 236 meshes with the driving gear 235, and the diameter of the driving gear 235 is 10-20 cm. One end of the transmission shaft 234 close to the speed reducer 232 is connected to the speed reducer 232 for transmission.

[0073] The cage hoop 238 is installed around the wire mesh at the nuclear inlet end and the nuclear outlet end of the cage 211, and the driven gear 236 is installed around the wire mesh on the cage hoop 238. The support rollers 239 are arranged below the lower side surfaces of the nuclear inlet end and the nuclear outlet end of the cage 211, and the support rollers 239 are installed on the bracket 160. The cage hoop 238 is supported on the support rollers 239, enabling the cage 211 to rotate freely on the support rollers 239.

[0074] The second motor 231 is connected to the speed reducer 232 through the second belt 233, and then drives the cage 211 to rotate under the drive of the transmission shaft 234, the driving gear 235, and the driven gear 236, and limits the rotation speed of the cage 211 to 1-20 revolutions per minute to prevent the jujube pits from not coming into sufficient contact with the brush roller 213 due to too fast rotation speed and thus not being effectively processed.

[0075] Thus, the working process of the wild jujube kernel cleaning can be understood as follows: The wild jujube kernels with remaining pulp and pericarp after being processed by the de-kerneling device enter the wire cage 211 of the kernel cleaning device through the kernel discharge channel 140. The second motor 231 is connected to the speed reducer 232 through the second belt 233, and then drives the wire cage 211 to rotate through the transmission shaft 234, the driving gear 235, and the driven gear 236. At the same time, when the wire cage 211 rotates, it can drive the brush roller 213 to roll synchronously. Since the wire cage 211 has a downward inclination angle, the wild jujube kernels gradually move downward towards the kernel discharge end of the wire cage 211 as the wire cage 211 rotates. During the downward movement, the wild jujube kernels come into contact with the brush roller 213, and the brush roller 213 keeps rolling, brushing off the pulp and pericarp adhered to the wild jujube kernels, thus separating the clean wild jujube kernels. Since the brush fibers on the brush roller 213 can extend 0.5 - 3 mm outside the wire cage 211 through the mesh holes on the wire cage 211, the pulp and pericarp brushed off can be pushed outside the wire cage 211 by the brush through the mesh holes on the wire cage 211, thus ensuring that the mesh holes of the wire cage 211 will not be sealed by the pulp and pericarp.

[0076] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
