Description

TECHNICAL FIELD

[0001] The application relates to the field of fish bone crushing and grinding technology equipment, in particular to a grinding device for preparing fish bone calcium. BACKGROUND

[0002] Fish bone refers to the bone of a fish, and the fish bone contains rich calcium, and eating the fish bone regularly can prevent osteoporosis, and is very beneficial to teenagers in the growth period and the middle-aged and the old in the bone aging period. Meanwhile, the fish bone contains rich trace elements and can promote the absorption of calcium by the human body. However, the fish bone is relatively sharp, and direct consumption is easy to cause harm to the human body, so the calcium in the fish bone needs to be extracted. When the fish bone calcium is extracted, the fish fillet with a small amount of fish meat needs to be crushed and ground to prepare surimi.

[0003] The fish bone is usually ground by using a grinder. In the crushing and grinding process, an appropriate amount of water needs to be added so that the fish bone can be more fully ground and stirred. The water adding speed and the water adding amount need to be strictly controlled by the worker according to the fish fillet adding speed. If the water adding amount is too small, the fish fillet cannot be fully crushed and ground. If the water adding amount is too large, the subsequent drying process of the surimi is prolonged.

[0004] According to the related technology in the prior art, the worker needs to manually add water to the fish fillet in the crushing and grinding process, and the worker needs to participate in the whole process. The water adding speed and the water adding amount are influenced by the subjectivity, and the viscosity degree of the surimi is prone to fluctuation. SUMMARY

[0005] In order to automatically add water to the grinder according to the fish fillet adding speed, the application provides a grinding device for preparing fish bone calcium.

[0006] The application provides a grinding device for preparing fish bone calcium, which adopts the following technical scheme:

[0007] The grinding device for preparing fish bone calcium comprises a shell, a grinding cavity, a feeding channel for fish fillet entering the grinding cavity and a discharging channel for surimi discharging from the grinding cavity are arranged in the shell, a grinding mechanism is arranged in the grinding cavity, a transmission wheel is rotationally connected to the shell and the rotation axis is perpendicular to the feeding direction, the edge of the transmission wheel extends into the feeding channel, a water adding sliding cylinder is arranged in the shell, a sliding block is slidably connected in the water adding sliding cylinder, a transmission rod for reciprocating sliding of the water adding sliding cylinder is hinged to the sliding block, the transmission rod is rotationally connected to the eccentric position of the wheel disc of the transmission wheel at the end away from the sliding block, a transfer groove is arranged on the sliding block, a water storage tank for storing water is arranged on the shell, a water supplement pipe for connecting the water storage tank and the water adding sliding cylinder and a pipe for connecting the water adding sliding cylinder are arranged in the shell, and the transfer groove is periodically connected with the water supplement pipe and the feeding channel respectively with the sliding of the sliding block.

[0008] By adopting the technical scheme, when the fish fillets are added into the grinding cavity from the feeding channel, the fish fillets drive the transmission wheel to rotate, the transmission wheel drives the transmission rod to periodically reciprocate, and then drives the sliding block to reciprocate in the water adding sliding cylinder, the transfer groove also reciprocates with the sliding block, when the transfer groove moves to a position communicated with the water supplement pipe, the water in the water storage tank enters the transfer groove, when the transfer groove moves to a position communicated with the feeding channel, the water in the transfer groove enters the feeding channel and mixes with the fish fillets, automatic water adding is realized, and when no fish fillets are added into the feeding channel, the water adding work stops, and the water can be automatically added into the grinding device according to the adding speed of the fish fillets.

[0009] Optionally, the side surface of the transmission wheel is provided with a protrusion for increasing the friction with the fish fillets.

[0010] By adopting the technical scheme, the protrusion can increase the roughness of the surface of the transmission wheel, the friction coefficient between the transmission wheel and the fish fillets is increased, and then the friction between the two is increased, so that the phenomenon of slipping between the transmission wheel and the fish fillets is avoided, and the transmission wheel can more accurately rotate with the addition of the fish fillets.

[0011] Optionally, the side surface of the transmission wheel is provided with a receiving groove, the receiving groove is provided with a clamping block matched in shape and size with the receiving groove, the clamping block is rotationally connected to the transmission wheel and the rotation shaft is arranged on the side of the clamping block moving in the forward direction with the transmission wheel, and a first elastic member is connected between the bottom wall of the receiving groove and the clamping block, when the first elastic member is in a natural state, the end of the clamping block away from the bottom wall of the receiving groove is out of the receiving groove, and when the clamping block moves to the position abutting against the side wall of the feeding channel with the transmission wheel, the clamping block is gradually embedded into the receiving groove.

[0012] By adopting the technical scheme, when the first elastic member is in a natural state, the end of the clamping block away from the bottom wall of the receiving groove is out of the receiving groove, which helps to increase the roughness of the surface of the transmission wheel, avoids the phenomenon of slipping between the transmission wheel and the fish fillets, and makes the transmission wheel more accurately reflect the adding speed of the fish fillets. At the same time, the side wall of the feeding channel and the side surface of the transmission wheel can be kept in abutting state, preventing small fish fillets from entering the gap between the transmission wheel and the side wall of the feeding channel.

[0013] Optionally, the feeding channel is provided with an abutting plate, the length direction of the abutting plate is parallel to the length direction of the feeding channel, the abutting plate is slidingly connected to the side wall of the feeding channel and the sliding direction is perpendicular to the length direction of the abutting plate, a second elastic member is connected between the abutting plate and the side wall of the feeding channel, and the second elastic member is arranged on the side of the abutting plate away from the transmission wheel.

[0014] By adopting the technical scheme, when the fish fillets are added to the feeding channel, the pressure between the fish fillets and the transmission wheel is small or even no contact between the fish fillets and the transmission wheel due to the small cross section of the fish fillets, so that the fish fillets cannot drive the transmission wheel to rotate. The abutting plate is arranged, when the fish fillets enter the feeding channel, the abutting plate is pushed to slide away from the transmission wheel, and the second elastic member is compressed, so that the abutting plate always maintains the trend of extruding the fish fillets towards the transmission direction, and the abutting state between the fish fillets and the transmission wheel is always maintained.

[0015] Optionally, a screw rod is arranged in the discharging channel to facilitate the discharge of the surimi, the length direction of the screw rod is parallel to the length direction of the discharging channel, and the size of the screw rod is matched with the discharging channel. The housing is provided with a discharging motor for driving the screw rod to rotate.

[0016] By adopting the technical scheme, the screw rod is arranged and driven to rotate by the discharging motor, which helps to timely discharge the surimi entering the discharging channel, improves the discharging speed, and prevents the discharging channel from being blocked.

[0017] Optionally, a compression block is arranged in the grinding cavity to pressurize the grinding space, the compression block is slidably connected with the inner wall of the grinding cavity, and the housing is provided with an extrusion cylinder for driving the compression block to slide, and the extrusion cylinder is arranged on the side of the compression block away from the discharging channel.

[0018] By adopting the technical scheme, the extrusion cylinder drives the compression block to extrude the fish fillets entering the grinding cavity towards the direction close to the grinding machine and the discharging channel, which helps to timely release space to accommodate new fish fillets, thereby reducing the resistance of adding fish fillets.

[0019] Optionally, a filter screen is arranged between the grinding cavity and the discharging channel to prevent large fish fillets from passing through.

[0020] By adopting the technical scheme, the fish fillets need to be fully ground in the grinding cavity before obtaining surimi, and the filter screen is arranged to prevent the fish fillets that have not been fully ground from being discharged into the discharging channel in advance, thereby ensuring the quality of the surimi.

[0021] Optionally, the grinding mechanism includes a grinding knife and a grinding motor for driving the grinding knife to rotate, and the shape of the filter screen is matched with the action range of the grinding knife.

[0022] By adopting the technical scheme, the shape of the filter screen is matched with the action range of the grinding knife, which can avoid that part of the fish fillets is left in the dead angle of the action of the grinding knife, so that the fish fillets can be fully ground.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. The speed and amount of water added manually during grinding of fish fillets are easily affected by subjective factors. When the fish fillets enter the feeding channel, the driving wheel is driven to rotate, and the driving rod is driven to move periodically and reciprocally, so that the sliding block moves reciprocally in the water adding sliding cylinder. The transfer groove moves reciprocally with the sliding block. When the transfer groove moves to a position communicating with the water supplement pipe, the water in the water storage tank enters the transfer groove. When the transfer groove moves to a position communicating with the feeding channel, the water in the transfer groove enters the feeding channel and mixes with the fish fillets, so that automatic water adding is realized. The water adding speed changes with the speed of adding fish fillets. When no fish fillets are added to the feeding channel, the water adding work stops. The water can be added to the grinder automatically according to the speed of adding fish fillets.

[0025] 2. A filter screen is arranged between the grinding cavity and the discharging channel to prevent large fish fillets from passing through. The shape of the filter screen is adapted to the action range of the grinding knife, so that part of the fish fillets can be prevented from remaining in the dead angle of the action of the grinding knife, and the fish fillets can be fully ground.
