Description

Technical Field

[0001] The invention relates to the technical field of cashew nut processing, in particular to a screening device for cashew nut processing. Background Art

[0002] When cashews are purchased and sold, their prices vary due to their size and quality grade, so the cashews need to be screened accordingly during the production and processing process after they are picked.

[0003] At present, there are two ways of screening and packaging: one is to use manual labor, that is, to use manual inspection; the other is to use mechanical equipment, that is, to use screening equipment to complete the screening effect of cashew nuts. Before screening the cashew nuts, whether it is manual screening or mechanical screening, the cashew nuts need to be washed. After washing, more water will adhere to the surface of the cashew nuts. Although manual screening can avoid the influence of water stains on cashew nut screening to a certain extent, it takes a long time. When using mechanical equipment for screening, the stacked cashew nuts will also stick together due to the water tension of the water stains, thereby affecting the screening effect of the machine itself.

[0004] Therefore, the existing demand is not met, and we have proposed a screening device for cashew processing. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] For example, see Figure 1-Figure 14 A screening device for cashew processing includes a processing table 1, a screening cavity 103 is provided inside the processing table 1, and through the setting of the screening cavity 103, unqualified cashews screened out by the screening component 2 can fall into the screening cavity 103. The screening component 2 is rotatably provided on the processing table 1, and the screening component 2 is composed of a rotating wheel 201 and a plurality of rotating rods 202. The rotating wheel 201 is rotatably provided at the inner wall of the processing table 1, and a plurality of third movable grooves 203 for the rotating rods 202 to slide are provided inside the rotating wheel 201. Since the rotating wheel 201 is also fixedly connected with the output end of an external motor provided on the processing table 1, when the user starts the external motor, the rotating wheel 201 will rotate, thereby driving the plurality of rotating rods 202 provided inside the rotating wheel 201 to rotate synchronously, so that the plurality of rotating rods 202 can complete the collection of cashews in sequence, and then complete the screening of cashews during transportation.

[0040] The first storage box 101 and the second storage box 102 are connected to both ends of the processing table 1 respectively. The first storage box 101 is used to hold cashew nuts to be screened, and the second storage box 102 is used to hold the screened cashew nuts. Through the above-mentioned arrangement, when the rotating wheel 201 rotates, the rotating rod 202 arranged at the bottom of the rotating wheel 201 will gradually approach the first storage box 101 due to the action of rotation, and since a blocking plate is also arranged at the front end of the rotating rod 202, when the rotating rod 202 rotates to the inside of the first storage box 101, the blocking plate arranged at the front end of the rotating rod 202 will take the cashew nuts to be screened and deliver them to the rotating rod 202, and the arrangement of the blocking plate and the guard plates on both sides can also prevent the cashew nuts from scattering from the rotating rod 202 during the subsequent rotation to a certain extent.

[0041] When the rotating rod 202 completes the collection of the cashew nuts, since the rotation of the rotating wheel 201 is still in progress, the rotating rod 202 will continue to rotate, and when the rotating rod 202 continues to rotate for a certain angle, the rotating rod 202 will flip over, and then the cashew nuts that are temporarily stored inside the rotating rod 202 and have been screened are transported to the second storage box 102. The above design not only improves the transportation efficiency of the cashew nuts, but also ensures the stability of the cashew nuts during transportation and the accuracy after transportation.

[0042] A second slide bar 205 is arranged above the moving bar 209, and a connecting bar 223 is also installed on the top of the moving bar 209. The connecting bar 223 is slidably arranged inside the second slide bar 205. Since the other end of the second slide bar 205 is slidably arranged inside the second moving groove 105, the second moving groove 105 is divided into a third moving station 1051, a fourth moving station 1052 and a fifth moving station 1053. Figure 3 It can be seen that the third mobile station 1051, the fourth mobile station 1052 and the fifth mobile station 1053 are connected, and the fourth mobile station 1052 is further opened away from the center position of the processing table 1 on the basis of the third mobile station 1051. Therefore, when the rotating rod 202 rotates following the rotating wheel 201, the second slide bar 205 will also slide inside the third mobile station 1051 in the second moving groove 105. When the second slide bar 205 slides from the third mobile station 1051 into the fourth mobile station 1052, the second slide bar 205 will drive the moving rod 209 to move away from the center position of the processing table 1.

[0043] A plurality of top support blocks 211 are equidistantly arranged on the top of the moving rod 209, two third sliding rods 210 are movably sleeved on the moving rod 209, and a third sliding groove 212 is also provided on the inner wall of the rotating rod 202 for the third sliding rod 210 to slide. A first extrusion rod 219 is installed on the side of the moving rod 209. Through the arrangement of the third sliding rod 210 and the third sliding groove 212, the moving rod 209 can be moved more stably.

[0044] The inside of the rotating rod 202 is provided with screening rods 208 for screening cashew nuts. There are two groups of screening rods 208, and each group of screening rods 208 is arranged at equal distances. A limiting groove 2081 is provided at the bottom of the screening rod 208. One end of one group of screening rods 208 with the limiting groove 2081 is slidably set on the inner wall of one side of the rotating rod 202, and the other group of screening rods 208 without the limiting groove 2081 has one end slidably set on the inner wall of the other side of the rotating rod 202.

[0045] Connecting slide grooves 226 are provided at the inner walls on both sides of the rotating rod 202 , and movable sliders 2082 are installed at both ends of the screening rod 208 , and the movable sliders 2082 are slidably arranged inside the corresponding connecting slide grooves 226 .

[0046] Through the above arrangement, when the moving rod 209 moves, several supporting blocks 211 arranged on the moving rod 209 will also move synchronously. It should be noted that the top and part of the bottom of the screening rod 208 are arranged as an arc surface. When the supporting block 211 moves, the screening rod 208 will move up accordingly under the contact of the supporting block 211. Since one end of the screening rod 208 with a limiting groove 2081 and one end of the screening rod 208 without a limiting groove 2081 are alternately arranged on the surface of one side of the rotating rod 202, when one screening rod 208 is supported by the supporting block 211, the adjacent screening rod 208 will not be supported by the supporting block 211 due to the limiting groove 2081. This arrangement is to avoid the situation where two adjacent screening rods 208 are alternately lifted up, and the cashew nuts that slip into the gap between the adjacent screening rods 208 may be squeezed by the two screening rods 208, thereby causing unnecessary damage.

[0047] A second return spring 232 is also provided between the movable slider 2082 and the connecting slide groove 226. Through the setting of the second return spring 232, after the corresponding screening rod 208 is propped up, it can also be quickly reset through the return elastic force of the second return spring 232. This setting is also for the subsequent support block 211 to pass through this screening rod 208 again, and still drive the screening rod 208 to move up accordingly, thereby completing the screening effect of the cashew nuts, allowing the broken cashew nuts to fall from the gap between the two screening rods 208, and at the same time facilitating the liquid adhering to the cashew nuts to flow out smoothly.

[0048] On the one hand, there is a gap between two adjacent screening rods 208. On the other hand, when the cashews are temporarily stored on the rotating rod 202, the cashews are also piled up between several screening rods 208. Therefore, when several screening rods 208 are moved upward, a wave shape will be formed between the screening rods 208 that have not been moved and the screening rods 208 that are moved. In addition, since there are several supporting blocks 211 on the moving rod 209, the supporting block 211 arranged at the rear end of the moving rod 209 will also support the same screening rod 208, thereby driving the same screening rod 208 to move up and down reciprocatingly. Through this reciprocating movement setting, the cashews stacked on the screening rod 208 can also produce corresponding shaking.

[0049] Since a lot of water will adhere to the surface of the cashew nuts after washing, even after the cashew nuts are transferred to the rotating rod 202, the stacked cashew nuts will adhere together due to water tension. Therefore, when the screening rod 208 moves up and down, the water adhering to the cashew nuts can be separated from the cashew nuts under the above-mentioned shaking, so that the subsequent shaking and screening of the cashew nuts can be more effectively performed.

[0050] When the stacked cashew screening rods 208 move up and down and shake, some cashews that are smaller in size or broken during transportation will also fall from the gap between two adjacent screening rods 208 into the screening chamber 103 under this shaking. This arrangement also effectively completes the screening effect of the cashews temporarily stored on the rotating rod 202.

[0051] In this embodiment: when the user starts the external motor, the rotating wheel 201 will rotate accordingly on the processing table 1, so that the several rotating rods 202 arranged inside the rotating wheel 201 can complete the cashew nut picking in sequence. When the rotating rod 202 completes the picking, through the setting of the second moving groove 105, the rotating rod 202 is rotated and moved, so that the moving rod 209 arranged on the rotating rod 202 moves away from the center position of the processing table 1, so that the top support block 211 arranged on the moving rod 209 can contact the several screening rods 208 in sequence, so that the screening rod 208 can move up and down in a reciprocating manner. This setting also allows the cashew nuts temporarily stored on the rotating rod 202 to complete the corresponding screening, and when the rotating rod 202 rotates to the flipping state, the cashew nuts temporarily stored on the rotating rod 202 and have completed the screening can also be smoothly transported to the inside of the second storage box 102, thereby effectively completing the transportation of the cashew nuts.

[0052] Through the above arrangement, not only the transportation of cashew nuts to be processed can be completed, but also compared with the prior art, the present solution can effectively complete the screening effect of cashew nuts during the transportation of cashew nuts, so as to improve the overall efficiency of cashew nut processing to a certain extent. It should be noted that liquid is provided inside the first storage box 101 and the screening cavity 103, so that the cashew nuts can float on the surface of the liquid, and the liquid inside the first storage box 101 and the screening cavity 103 can be used to achieve the effect of screening and removing impurities in the cashew nuts.

[0053] Embodiment 2: This embodiment is intended to solve the problem that when the moving rod 209 moves, it can only support the screening rod 208 at the inner wall of one side of the rotating rod 202, so some cashews cannot be effectively screened. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 14 The rotating rod 202 is also equipped with a first extrusion block 213 and a second extrusion block 217 that change the moving position of the moving rod 209. When the second sliding rod 205 slides to the maximum displacement point of the third moving station 1051, the moving rod 209 will come into contact with the first extrusion block 213. Since the first extrusion block 213 is also provided with an extrusion slope, the moving rod 209 will be pressed by the extrusion slope of the first extrusion block 213. Figure 6 Move in the direction of the third sliding slot 212.

[0054] It should be noted that, on the one hand, the moving rod 209 and the third sliding rod 210 are movably connected, so when the moving rod 209 moves under the squeezing of the first squeezing block 213, the moving rod 209 will only move on the third sliding rod 210 and will not get stuck;

[0055] On the other hand, when the moving rod 209 contacts the first extrusion block 213, the top support block 211 set on the moving rod 209 is also just located between the corresponding adjacent gaps of the screening rods 208. Therefore, even if the moving rod 209 is still moved away from the center position of the processing table 1 driven by the second slide rod 205, the top support block 211 on the moving rod 209 will not squeeze the screening rod 208.

[0056] A stop block 224 for positioning is installed on the connecting rod 223, and two sets of stop springs 225 for fixing the stop block 224 are also arranged inside the second slide bar 205. Through this arrangement, on the one hand, the second slide bar 205 can slide inside the second moving groove 105 by Fig.13 The limiting spring piece 225 in the connecting rod 223 completes the positioning of the connecting rod 223, and then when the second sliding rod 205 moves, the moving rod 209 will also move synchronously with the second sliding rod 205; on the other hand, when the moving rod 209 is squeezed by the first squeezing block 213, Figure 6When the moving rod 209 moves in the direction of the third slide groove 212, the limit block 224 will squeeze the limit spring piece 225, so that the limit spring piece 225 releases the limit on the limit block 224, and after the moving rod 209 stops moving, the limit block 224 will be connected to the inside of the next set of limit spring pieces 225 to complete the positioning of the moving rod 209.

[0057] The rotating rod 202 is also provided with a first extrusion block 213 and a second extrusion block 217 for changing the moving position of the moving rod 209 . A first airbag 216 is installed on one side of the first extrusion block 213 , and a second airbag 218 is installed on one side of the second extrusion block 217 .

[0058] The first airbag 216 and the second airbag 218 are both connected to the extrusion plate 230. The first airbag 216 and the second airbag 218 are both provided with a connecting spring 221. A second extrusion rod 222 is also connected between the connecting spring 221 and the corresponding extrusion plate 230. It should be noted that according to Figure 7 It can be seen that the extrusion plate 230 is composed of a fixed plate 2301 and a movable plate 2302, and the movable plate 2302 is arranged at the inclined surface position of the second extrusion block 217. Fig.14 It can be seen that the movable plate 2302 is slidably arranged inside the fixed plate 2301, and a first return spring 231 is arranged between the fixed plate 2301 and the movable plate 2302. The first return spring 231 is used to realize the subsequent telescopic movement of the movable plate 2302.

[0059] Through the above arrangement, the moving rod 209 can be brought into contact with the extrusion plate 230 connected to the first airbag 216 while being squeezed and moved by the first extrusion block 213. The moving rod 209 can complete the squeezing of the first airbag 216 so that the first airbag 216 can complete the subsequent air supply effect on the connecting air groove 228.

[0060] At the same time, when the second slide bar 205 moves from the fourth moving station 1052 to the next third moving station 1051, the second slide bar 205 will also drive the moved moving rod 209 to reset accordingly, so that the top support block 211 provided on the moving rod 209 can complete the reset process in sequence. Figure 6 The squeezing support of the screening rod 208 arranged on the inner wall of the rotating rod 202 is arranged in a staggered manner. Since the limiting grooves 2081 provided on the two adjacent screening rods 208 are arranged in a staggered manner, the screening rod 208 supported by the support block 211 during the movement from right to left is completely different from the screening rod 208 supported from left to right, thereby achieving the effect of vibration of the support for the cashew nuts on each screening rod 208. Through the above-mentioned resetting movement, the screening effect of the cashew nuts accumulated on this part of the screening rod 208 can be effectively completed, thereby effectively improving the screening efficiency of the cashew nuts.

[0061] Moreover, before the second slide bar 205 moves from the fourth moving station 1052 to the next third moving station 1051, the first extrusion rod 219 disposed on the moving rod 209 will also contact the second extrusion block 217, and the extrusion of the second extrusion block 217 can also smoothly drive the moving rod 209 to move. Figure 6 The movable rod 209 is reset in a direction away from the third sliding groove 212, and during the reset process of the movable rod 209, the movable rod 209 can also complete the squeezing effect on the second airbag 218, thereby allowing the second airbag 218 to complete the air supply effect on the corresponding connecting air groove 228.

[0062] It should be noted that the first airbag 216 and the second airbag 218 are both provided with a connecting spring 221 and a second squeezing rod 222. By setting the connecting spring 221 and the second squeezing rod 222, after the squeezing of the moving rod 209 is released, the first airbag 216 and the second airbag 218 can be quickly reset by the reset elastic force of the connecting spring 221, so that when the moving rod 209 performs the corresponding movement subsequently, the first airbag 216 and the second airbag 218 can still play the corresponding effect.

[0063] The first airbag 216 and the second airbag 218 are respectively connected with first connecting air pipes 227 . The inner walls on both sides of the rotating rod 202 are provided with connecting air grooves 228 . The two first connecting air pipes 227 are respectively connected with the corresponding connecting air grooves 228 .

[0064] The connecting air groove 228 is connected to the corresponding plurality of screening rods 208 through the corresponding second connecting air pipes 233 , and the plurality of screening rods 208 are each provided with a plurality of air outlet holes 229 .

[0065] Through the above-mentioned arrangement, no matter whether the first airbag 216 or the second airbag 218 is squeezed, the first airbag 216 and the second airbag 218 will transport the internal gas through the corresponding first connecting air pipe 227 to the corresponding connecting air groove 228. Through the arrangement of several second connecting air pipes 233, the gas inside the connecting air groove 228 can be transported to the inside of the screening rod 208 in turn. It should be noted that the second connecting air pipe 233 has a certain elasticity. Therefore, even after the screening rod 208 moves, the elasticity of the second connecting air pipe 233 can ensure the air supply effect to the screening rod 208 within a certain range. Therefore, the corresponding several screening rods 208 will be filled with a certain amount of gas, and this part of the gas can be used through the air outlet 229 opened on the screening rod 208 to complete the cleaning effect of the debris adhering to the adjacent screening rod 208, and to a certain extent, the screening efficiency of several screening rods 208 is improved.

[0066] The first slide bar 204 is installed on the side of the rotating rod 202. The inner wall of the processing table 1 is provided with a first moving groove 104 and a second moving groove 105. The first moving groove 104 is divided into a first moving station 1041 and a second moving station 1042. Figure 3 It can be seen that the first moving station 1041 and the second moving station 1042 are connected, but the opening position of the second moving station 1042 is further moved closer to the center of the processing table 1 on the basis of the first moving station 1041. Therefore, when the rotating rod 202 rotates with the rotating wheel 201, the first sliding bar 204 set on the rotating rod 202 will slide inside the first moving station 1041 of the first moving groove 104. Since the rotating rod 202 is slidably set inside the third moving groove 203, when the first sliding bar 204 slides from the first moving station 1041 into the second moving station 1042, the first sliding bar 204 will drive the rotating rod 202 to move closer to the center of the processing table 1. The movement of the position, when the first sliding rod 204 completely slides into the second moving station 1042, the rotating rod 202 is just in the horizontal position after the flipping. Therefore, this arrangement not only allows the rotating rod 202 to avoid collision with the second storage box 102 and thus jamming when it moves to a position close to the second storage box 102, but the movement of the rotating rod 202 also allows the rotating rod 202 in the horizontal state after flipping to have no effect on the rotating rod 202 that is flipping and dumping, thereby allowing the flipped and dumped rotating rod 202 to smoothly transport the cashew nuts temporarily stored inside the rotating rod 202 to the second storage box 102.

[0067] At the same time, since the fifth moving station 1053 in the second moving groove 105 is further opened toward the center of the processing table 1 on the basis of the third moving station 1051, when the rotating rod 202 slides from the first moving station 1041 into the second moving station 1042 through the first slide bar 204, the second slide bar 205 will also slide from the third moving station 1051 into the fifth moving station 1053. This setting is also to avoid the rotating rod 202 from getting stuck if the second slide bar 205 does not move after the moving.

[0068] It should be noted that the rotating wheel 201 is provided with a first slide groove 206 for the first slide bar 204 to slide. Therefore, when the first slide bar 204 drives the rotating rod 202 to move closer to the center of the processing table 1, the first slide groove 206 can also avoid jamming.

[0069] It should be noted that a second slide groove 207 for the second slide bar 205 to slide is provided on the rotating wheel 201 and the rotating rod 202. This ensures that even if the rotating rod 202 moves closer to the center position of the processing table 1, the second slide bar 205 will not get stuck due to the opening of the second slide groove 207. It should be noted that the second slide bar 205 is slidably arranged on the inside of the second slide groove 207 provided on the rotating rod 202 by means of a slider. Through this restriction, the two can only slide and will not separate. In addition, this arrangement is also to avoid that when the second slide bar 205 moves to the first extrusion block 213 or the second extrusion block 217, a pulling force will be generated on the connecting rod 223. If the second slide bar 205 is not restricted, the connecting rod 223 may pull the second slide bar 205 out of the second movable groove 105, thereby affecting the subsequent movement effect.

[0070] At the same time, due to the continued rotation of the rotating wheel 201, the first sliding rod 204 will slide from the second movable station 1042 into the first movable station 1041 again, so that the rotating rod 202 is reset to the initial position again, so that the rotating rod 202 can complete the transportation and screening effect of the cashew nuts again during the subsequent rotation process.

[0071] In this embodiment: before the moving rod 209 moves to the maximum displacement, the moving rod 209 will contact the first extrusion block 213, and under the extrusion of the first extrusion block 213, the moving rod 209 will move accordingly. After the moving rod 209 moves, the resetting of the moving rod 209 will allow the supporting block 211 to complete the supporting effect of the screening rod 208 set on the other side of the rotating rod 202, so that the cashew nuts that have not been screened can also be effectively screened under this movement, thereby further improving the screening efficiency of the cashew nuts.

[0072] When the moving rod 209 moves away from the center of the processing table 1, through the setting of the first airbag 216, when the moving rod 209 completes the movement, the moving rod 209 will also complete the squeezing of the first airbag 216, so that the gas inside the first airbag 216 can be transported to the corresponding screening rod 208, and this part of the gas can be used through the air outlet 229 opened on the screening rod 208 to complete the cleaning effect of the debris adhering to the adjacent screening rod 208. Similarly, when the moving rod 209 is reset, the moving rod 209 will also squeeze the second airbag 218, so that the gas inside the second airbag 218 will also be transported to the corresponding screening rod 208, thereby completing the cleaning effect of the debris adhering to the adjacent screening rod 208.

[0074] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
