Therefore, the development of the relevant freshwater fish pretreatment processing technology and device has important significance for improving the processing efficiency and the fish utilization rate of freshwater fish bodies.
The head and tail directional conveying of the fish body is an important operation in the industrial processing process of the fish body. Before fish pretreatment processing such as removing heads and tails of fish bodies, cutting and removing dirty fish bodies, the fish bodies are generally required to be conveyed in a certain head and tail direction so as to improve the processing speed and efficiency. The traditional mode is that manual operation is adopted, so that the labor intensity is high, the efficiency is low, and the cost is high.

The tooth height is 4-6mm, the tooth thickness is 4-6mm, and the tooth length is 9-11 mm.
The distance between adjacent teeth parallel to the horizontal reciprocating vibration direction is 5-10 mm.
The fish body separating device is characterized by further comprising a fish body lifting device and a fish body separating device, wherein the discharge end of the fish body lifting device is located above the feed end of the fish body separating device, the discharge end of the chute of the fish body separating device is located above the feed area of the directional conveying belt, and the discharge areas at the two ends of the directional conveying belt are connected with inclined slideways.
The fish body separating device comprises a hopper, a shifting wheel and a sliding chute, the shifting wheel is positioned at the bottom of the hopper, the feeding end of the sliding chute is positioned below the shifting wheel, the discharging end of the sliding chute is positioned above the feeding area of the directional conveying belt, and the shifting wheel is connected with a second driving device.
In view of the problems in the background art, the inventor makes the following improvements:
(1) the horizontal reciprocating vibration table is obtained by using a special vibration principle, namely horizontal reciprocating vibration, and matching with a horizontally arranged vibration table top, wherein the vibration table top is driven by a first driving device through a transmission part to enable the vibration table top to generate horizontal reciprocating vibration. The research shows that: the fish scale structure and the gill structure on the surface of the fish body have the characteristic of directional growth, namely the fish scales and the gill grow in a stacked mode from head to tail and are achieved through friction anisotropy when the fish scales and the gill structure interact with a horizontal reciprocating vibration table surface, namely when the fish body slides on the surface of the vibration table surface along the head-tail direction respectively, the friction force borne by the fish body along the scale direction is smaller than the friction force borne by the fish body along the scale-reverse direction. When the vibration table-board vibrates horizontally and reciprocally, when the vibration direction is along the direction of the head of the fish body (the scale-resisting direction), the fish body moves towards the tail direction relative to the vibration table-board, so that a friction force is generated along the direction of the head of the fish body (the scale-resisting direction) and a corresponding displacement is generated, when the vibration table-board moves along the direction of the tail (the scale-resisting direction), the fish body continues to slide along the direction of the head due to inertia, the fish body moves towards the direction of the head relative to the directional conveyor belt, so that a friction force is generated along the direction of the tail (the scale-resisting direction) of the fish body and a corresponding displacement is generated, so that the friction force borne by the fish body along the scale direction is smaller than the friction force borne by the fish body towards the scale-resisting direction, the difference is obvious, and the displacement along the head direction is always larger than the displacement along the tail direction in the whole period, so as to realize the directional conveying of the fish body along the head direction (namely the direction of two ends of the vibration table surface).
Moreover, the horizontal reciprocating vibration mode can achieve the technical effects of middle-section feeding and synchronous discharging at two ends, so that the conveying efficiency can be greatly improved; moreover, because the vibration table top level sets up, does not have the acceleration that the fish body slided, the fish body can realize effective head and the tail location in shorter stroke, therefore the vibration table top can design shorter, when improving fish body conveying efficiency, has reduced equipment volume again and has taken up an area of the space.
(2) The surface of the directional conveying belt is uniformly provided with protruded teeth along the horizontal reciprocating direction, and the combination of the horizontal reciprocating vibration and the vibration table surface with the tooth-shaped protrusions is a necessary condition for realizing the head-tail directional conveying of the fish body, and the horizontal reciprocating vibration and the vibration table surface with the tooth-shaped protrusions are not limited. The teeth protruding from the surface of the directional conveying belt can act with fish scales and fish gills in the horizontal reciprocating vibration process, so that the difference between the friction force applied to the fish body in the scale-facing direction and the friction force applied to the fish body in the scale-reversing direction is greatly increased, and the quick and effective positioning is realized.
Furthermore, the larger the difference between the friction force applied to the fish body in the scale-oriented direction and the friction force applied to the fish body in the scale-inverted direction is, the faster the head and tail orientation speed of the fish body is, and the higher the accuracy is. The inventor researches and discovers that the two sides of the tooth and the side surface vertical to the horizontal reciprocating vibration direction are vertical surfaces, the area of the top surface of the tooth is not more than that of the bottom surface, the top surface of the tooth is a contact surface with the fish body, the smaller the area is better, and the most preferable tooth shape can be a tooth with a triangular, trapezoidal or square section (a section vertical to the horizontal reciprocating vibration direction) or other shapes meeting the two conditions.
Further, the size and spacing of adjacent teeth are related to the size of the scales of fish, preferably the height of the teeth is 4-6mm, the thickness of the teeth is 1-3mm, the length (maximum length) of the teeth is 4-6mm, and the spacing between adjacent teeth parallel to the horizontal reciprocating vibration direction is preferably controlled to be 5-10 mm.
Furthermore, the vibration amplitude and frequency of the horizontal reciprocating vibration table are related to the positioning efficiency, and are not suitable to be too small or too large. When the frequency and the amplitude of the vibration table surface are small, the acceleration of the vibration is possibly smaller than the maximum static friction force of the fish body in the scale following direction or the scale inversion direction, at the moment, the fish body does not have relative movement trend relative to the vibration table surface, and can move along with the vibration table surface, so that the obvious phenomenon of head and tail directional conveying can not occur; the fish body head and tail directional conveying effect on the vibration table top can be evaluated by using the directional conveying speed, and relevant experimental research shows that the fish body head and tail directional conveying speed is increased along with the increase of the vibration frequency and the vibration amplitude of the vibration table top, but the larger the vibration frequency and the vibration amplitude is, the better the fish body head and tail directional conveying effect is, when the vibration frequency and the vibration amplitude are increased to a certain degree, the increased amplitude of the fish body head and tail directional conveying speed is reduced, namely, the influence of the continuous increase of the vibration frequency and the vibration amplitude of the vibration table top on the fish body head and tail directional conveying is reduced, the overlarge vibration frequency and vibration amplitude are, the stability of the directional equipment is reduced, and the power. Preferably, the vibration amplitude is 100mm-180mm, and the vibration frequency is 3hz-5 hz.
