Technical Field
[0001] The utility model relates to the technical field of visual selection, in particular to a material distribution device and a conveying device of a visual selection machine. Background Art
[0002] As is known, in a visual selection machine in the visual selection field, a conveying roller of a conveying device is usually used to drive a conveyor belt to convey materials to be screened (such as nut kernels and beans). A visual recognition mechanism in the visual selection machine recognizes the materials on the conveyor belt to identify features such as the quality, shape, and type of the materials. Then, the planar position of the recognized materials is located. Based on the positioning information and the conveying speed of the conveyor belt, a rejection mechanism rejects the recognized materials that need to be rejected.
[0003] Generally, a vibrating mechanism is further arranged at the rear end of the conveying device to make the materials fall on the conveyor belt in multiple columns and at intervals from each other and then be conveyed by the conveyor belt.
[0004] However, for special-shaped materials (mostly non-circular materials, such as scattered walnut kernels and cashew nuts), after being distributed by the vibrating mechanism and falling on the conveyor belt, some material particles still overlap or are close to each other and are not separated from each other, thus affecting the subsequent recognition and rejection work.

[0031] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted in this utility model.
[0032] As Figure 1 and Figure 2 shown, an embodiment of this utility model discloses a material distribution device and a conveying device of a visual selection machine including this material distribution device. The conveying device further includes a vibrating mechanism 50 and a conveying platform (to distinguish it from the conveying platform in the material distribution device, this conveying platform may be referred to as the second conveying platform 60). The material distribution device is arranged in front of the vibrating mechanism 50, and the second conveying platform 60 is arranged in front of the material distribution device. After the material passes through the vibrating mechanism 50 and the material distribution mechanism in sequence, it is conveyed forward by the conveyor belt (to distinguish it from the conveyor belt of the conveying platform in the material distribution device, this conveyor belt may be referred to as the second conveyor belt 61) of the second conveying platform 60 in a multi-column arrangement. A visual recognition mechanism is arranged above and / or below the second conveyor belt 61. The visual recognition mechanism is used to recognize the material on the second conveyor belt 61. An ejection mechanism is arranged in front of the visual recognition mechanism. The ejection mechanism is used to eject the material that is required to be ejected and recognized by the recognition mechanism.
[0033] The vibrating mechanism 50 has a guide plate 51. A plurality of guide grooves 511 are arranged on the guide plate 51. When the vibrating mechanism 50 provides vibration, the material is divided into multiple columns by the guide grooves 511 on the guide plate 51 and moves forward and falls onto the material distribution device.
[0034] The material distribution device includes: a conveying platform (to distinguish it from the second conveying platform 60, this conveying platform may be referred to as the first conveying platform 10), a material distribution mechanism, a jet nozzle 33 and an impurity collection tank 40.
[0035] The first conveyor belt 11 is used to receive multiple columns of materials discharged from the material guiding tray 51 and convey the multiple columns of materials forward. There are multiple material distribution mechanisms, and the multiple material distribution mechanisms are arranged side by side in the width direction of the first conveyor belt 11; each material distribution mechanism includes a material disturbing component 21 and a separating component 22, the separating component 22 is located in front of the material disturbing component 21 and is butted against the material disturbing component 21; the material disturbing component 21 includes two relatively arranged material disturbing plates 211, both of the two material disturbing plates 211 are inclined, and, the two material disturbing plates 211 enclose an "eight" shape with the front port smaller than the rear port, and, the front ports of the two material disturbing plates 211 correspond to the two material guiding grooves 511 of the material guiding tray 51 of the vibrating mechanism 50, so that, the two columns of materials falling on the first conveyor belt 11 are located between the two material disturbing plates 211; the separating component 22 includes two outer guiding plates 221 and two inner guiding plates 222, the two outer guiding plates 221 and the two inner guiding plates 222 define two guiding channels in an "eight" shape, the two inner guiding plates 222 are pivotally connected at the rear end so that the included angle between the two inner guiding plates 222 is adjustable, so as to be able to adjust the angle of the two guiding channels. Preferably, a dulling component is arranged at the pivoting area of the two inner guiding plates 222 to avoid forming a sharp top at the pivoting area and damaging the materials. The air jet nozzle 33 is arranged above the material distribution mechanism to spray air flow towards the material distribution mechanism to make the light impurities move forward, and the impurity collecting trough 40 is arranged in front of the first conveying platform 10 to receive the light impurities. Preferably, a front cross beam 32 and a rear cross beam 31 are horizontally arranged on the first conveying platform 10, the material disturbing component 21 is fixed to the rear cross beam 31, the separating component 22 is fixed to the front cross beam 32, and the air jet nozzle 33 is installed at the rear cross beam 31.
[0036] The working process of the material distribution device is introduced below.
[0037] Under the action of the vibrating mechanism 50, the materials are divided into multiple columns on the material guiding tray 51 and are discharged from the front end of the material guiding tray 51 along the material guiding grooves 511 and fall on the first conveyor belt 11 of the first conveying platform 10.
[0038] Every two columns of materials fall between the two material disturbing plates 211 of each material disturbing component 21. Since both of the two material disturbing plates 211 are inclined and enclose an "eight" shape, during the forward movement of the two columns of materials along with the first conveyor belt 11, they will contact the material disturbing plates 211. Since the plate surface of the material disturbing plate 211 forms a certain angle with the conveying direction of the first conveyor belt 11, therefore, the material disturbing plate 211 generates a resistance (the resistance can be frictional force or thrust) on the materials contacting it, thereby changing the motion state of the materials, specifically changing the speed of the materials. If one of the materials that are overlapped or close to each other contacts the material disturbing plate 211, the motion state of this material will change, thereby generating a relative motion with respect to the non-contact material, and further may cause the separation of the two materials. For example, as Figure 2As shown, the walnut kernels A and B with interlocking special-shaped structures moving synchronously move away from each other after walnut kernel A contacts the material disturbing plate 211, as the motion state of walnut kernel A changes relative to walnut kernel B. If two materials that are interlocked or approaching each other both contact the material disturbing plate 211, since the forces exerted on the two materials by the material disturbing plate 211 cannot be the same, the degrees and directions of the changes in the motion states of the two materials cannot be the same either. Therefore, the two materials may also separate.
[0039] It should be noted that: Of course, theoretically speaking, after two materials moving synchronously and separated from each other contact the material disturbing plate 211, the two materials may instead move closer to each other or even interlock. However, during the actual test of this material separating device, the probability that two materials separated from each other due to contact with the material disturbing plate 211 move closer or even interlock is very small, much smaller than the probability that two materials that are interlocked or approaching each other due to contact with the material disturbing plate 211 move away from each other. Moreover, it was found during the test process that: By increasing the length of the material disturbing plate 211, the probability of moving away can be significantly increased, and by increasing the length of the material disturbing plate 211, the materials can be arranged at more uniform intervals.
[0040] The "V"-shaped structure of the two material disturbing plates 211 of the material disturbing member 21 causes the two columns of materials to move closer to each other while moving forward, and then are discharged from the front port of the material disturbing member 21, and then enter the separating member 22. Subsequently, the two guiding channels defined by the outer guiding plate 221 and the inner guiding plate 222 of the separating member 22 cause the two columns of materials to move away from each other again, and then the two columns of materials are discharged from the front ports of the two guiding channels and finally fall onto the second conveyor belt 61 of the second conveying platform 60. During the process of the materials passing through the separating member 22, the separating member 22 also has a certain separating effect on the materials that are still in an interlocked or approaching state. For example, when the materials pass through the rear pivoting area of the two inner guiding plates 222, the inner guiding plates 222 have a separating effect on the two materials. Another example is that the outer guiding plate 221 or the inner guiding plate 222 has a separating effect on the materials contacting them. Thus, the probability that the materials conveyed by the second conveyor belt 61 are in an interlocked or approaching state is reduced to the greatest extent, so as to improve the recognition accuracy of the visual recognition mechanism for the materials.
[0041] When the materials pass through the material separating device, the air nozzles 33 eject airflows to drive light impurities (such as the skins of the materials) to move forward and enter the impurity collecting trough 40.
