Description

Device for removing shell and tail of snail

technical field

The invention relates to special equipment for processing snails, more specifically, it relates to a device for removing shell tails of snails.

Background technique

Snail is an important aquatic benthic animal, which can be eaten in addition to purifying and protecting the water environment. Snails are cheap and good in quality, and have high nutritional value. Modern science has proved that snails have comprehensive nutrients, including 11.4 grams of protein, 3.8 grams of fat, and 1.5 grams of carbohydrates per 100 grams; in addition, they also contain inorganic salts, vitamin A, thioflavin, niacin, etc. Therefore, the demand for snails as food is also increasing. It is necessary to remove the tail of the snail before eating, so as to remove the impurities in the tail and make it easier to eat. So you need to use the snail tail removal machine.

From the current situation of the snail tail removal machine, the current snail tail removal machine has a drum-type tail removal machine, such as a kind of snail tail removal machine whose publication number is CN210580759U, which protrudes the tail of the snail out of the circumference of the drum through the drum. surface, and then remove the tail through the cutter, so as to realize the tail removal. However, when the snail rolls in the drum, its shell is prone to damage, especially the snail after the tail has been removed. In addition, such as the tail removal machine disclosed by the publication number CN108887366A, through the setting of the screening part, funnel part, push mechanism, control device and other components, the snail is placed in the tail-down state before the tail is removed. Then the snails are placed one by one into the conical groove to be cut off. However, when this tail removal machine is implemented, it cannot ensure that the tail of each snail is all facing one direction, and there will be a problem of omission. And the snails need to be removed one by one, which is less efficient and can not meet the requirements of removing the tails of large quantities of snails.

Generally speaking, judging from the current snail tail removal machines on the market, most of them need to adjust the direction of the snail tails to the same upward or downward direction, and need to remove the tails one by one. The efficiency is low and it is not suitable for large batches. The tail removal requirements of snails.

Detailed ways

Below in conjunction with embodiment, the present invention is further described, but does not constitute any restriction to the present invention, anyone makes the limited number of amendments in the scope of claims of the present invention, still within the scope of claims of the present invention.

Referring to Fig. 1-Fig. 5, a shell tail removal device for snails according to the present invention includes an installation box 1, a feeding box 2, a conveyor, a resetter 6, a shear assembly and a collection frame 11. Wherein, the feeding box 2, the conveyor, the arranger 6 and the cutting assembly are all installed in the installation box 1, and the collecting frame 11 is arranged at the output end of the conveyor.

Feeding box 2 is used for pre-storing the snails to be tailed. A conical storage hopper 21 is provided in the feeding box 2 , and a blanking passage 22 connected thereto is provided below the conical storage hopper 21 . An intermittent blanking mechanism is installed in the conical storage hopper 21, so that the prestored snails fall into the blanking channel 22 in a periodic intermittent blanking mode. A reciprocating blanking mechanism is installed in the blanking channel 22, which is used for the horizontal reciprocating vibration treatment of the falling snails, so that the snails fall evenly. The falling snails finally fall from the outlet at the bottom of the feeding box 2 .

In order to realize the periodic intermittent blanking function of the intermittent blanking mechanism, the intermittent blanking mechanism of this embodiment includes a conical plate 25 , a connecting rod 24 and an electric telescopic rod 23 . The conical plate 25 is movably inserted in the conical storage hopper 21, and the conical plate 25 matches the bottom of the conical storage hopper 21, so that the conical plate 25 can completely seal the bottom of the conical storage hopper 21; Rod 24 is fixedly installed on the top of conical plate 25, and the top of feeding box 2 is fixedly installed with a fixed frame 20, and electric telescopic rod 23 is fixedly installed in fixed frame 20, and the flexible end of electric telescopic rod 23 and connecting rod 24 are away from cone One end of shaped plate 25 is fixedly connected.

The conical plate 25 is driven to reciprocate up and down by the electric telescopic rod 23 . When the conical plate 25 moves upwards, its contact position with the conical storage hopper 21 will be separated, so that there is a gap between the conical plate 25 and the conical storage hopper 21, and the snail can drop to the falling position through the gap. In the feed channel 22. When the conical plate 25 moves downward and contacts the conical storage hopper 21 , the gap will be closed, and the snail is blocked in the conical storage hopper 21 . Reciprocating in this way, the periodic intermittent blanking function is realized. And conical plate 25 is set to conical shape, is conducive to the agitation of snail in the conical storage hopper 21, can effectively prevent that conical plate 25 and the conical storage hopper 21 phase separations when snail takes place blockage and can not blanking phenomenon.

In order to realize uniform blanking of snails in the blanking channel 22, the reciprocating blanking mechanism of this embodiment includes a buffer net 26, a reciprocating screw mandrel 27 and a motor. The mesh unilateral length of the buffer net 26 is 1.2-1.5 times of the body width of the snail, so that the snail passes through the buffer net 26. The buffer net 26 is slidably installed in the blanking channel 22, and the buffer net 26 always blocks the blanking channel 22 during the moving process. Its specific implementation method can be that the blanking channel 22 is set as a square, the two ends of the buffer net 26 all penetrate and extend to the outside of the blanking channel 22, and both sides of the buffer net 26 pass through the slide rails and the blanking channel 22. Swipe to connect. In this way, it can be ensured that the buffer net 26 can always block the blanking channel 22 when the sliding distance of the buffer net 26 is less than the length of the buffer net 26 extending to the outer portion of the blanking channel 22 .

The reciprocating screw mandrel 27 is rotatably installed on the outer wall of the charging box 2, and one side of the charging box 2 is provided with a through groove, and the slide block of the reciprocating screw mandrel 27 runs through the through groove and is fixedly connected with the buffer net 26, and the slide block of the reciprocating screw mandrel 27 The moving direction is consistent with the sliding direction of the buffer net 26 . The motor is fixedly installed on the side wall of the charging box 2, and the output shaft of the motor is fixedly connected with the reciprocating screw mandrel 27. The reciprocating movement of the buffer net 26 can be realized through the driving action of the motor, thereby realizing the uniform blanking of the snails. And when the snail falls on the buffer net 26, the buffer net 26 can buffer the snail, which can effectively reduce the falling speed of the snail and reduce the damage of the snail.

Conveyor is positioned at the below of feed box 2, and it is used for receiving the snail that falls from feed box 2. The conveyor has the same structure as the conveyors on the market, and is mainly composed of a motor, a driving wheel 4, a driven wheel 5 and a conveyor belt 3. As shown in FIG. 3 , the difference between the conveyor of this embodiment and the traditional conveyor is that the conveyor belt 3 of this embodiment is provided with a plurality of through-type screw grooves 7 arranged in combination. In addition, in this embodiment, the conveying direction of the conveyor is used as the row of through-type screw grooves 7 arranged and combined. Both the driving wheel 4 and the driven wheel 5 run through the inner ring of the conveyor belt 3 , and the peripheral surfaces of the driving wheel 4 and the driven wheel 5 are provided with through-type transverse slots 16 matching the through-type screw grooves 7 .

The output end of the conveyor is positioned at the outside of the installation box 1, and the collection frame 11 is arranged below the output end of the conveyor for receiving the tailed snails.

The through-type screw groove 7 is used to hold a snail, and its inner cavity is a tapered structure. Specifically, take the through-type screw groove 7 on the surface of the conveyor belt 3 as an example, the upper and lower sides of the through-type screw groove 7 have no bottom, and the big mouth is on the top and the small mouth is on the bottom. When the snails with the same specifications or close to them fall into the through-type screw groove 7, the tails of the snails are either up or down, as shown in Figure 5. The upright snail 12 is the tail down, and the inverted snail 14 is the tail down. . When the tail of the snail is facing down, its tail is just exposed outside the small mouth, and its cutting position is shown as the lower cutting line 15 in Figure 5; The cutting position is as shown in the upper cutting line 13 in Figure 5, so as to achieve the purpose of removing the snail tail in the through-type screw groove 7. In addition, according to statistics, the apex angle of the cone of the snail is 52-60°, therefore, the angle between the opposite surfaces of the through-type screw groove 7 is set to be the same, so as to achieve better dressing and tail removal effects.

After the snail falls on the conveyor surface, some snails will not completely fall into the through-type screw groove 7, for example, the snail is horizontally placed on the through-type screw groove 7 opening. In order to make these snails that do not fully fall into the through-type screw groove 7 be placed in the through-type screw groove 7, the present embodiment is realized by the resetter 6.

As shown in FIG. 4 , the arranger 6 includes a base 61 and several finger posts 62 . The base 61 is arranged above the conveyor on one side of the cutting assembly, and several finger columns 62 are fixedly arranged on the bottom of the base 61 . Finger posts 62 are arranged between every two adjacent rows of through-type screw grooves 7 . When the snail does not completely fall into the through-type screw groove 7, the two ends of the snail will protrude from the range of the upper opening of the through-type screw groove 7, and when it passes through the finger-shaped post 62, the finger-shaped post 62 will be formed with it. Intervene to make it move. Because the gap between the through-type screw grooves 7 is very narrow, the moving snails will lose their balance, and then fall in the through-type screw grooves 7, thereby realizing the placement of the snails.

Since the snail shell is relatively brittle, in order to reduce the phenomenon of damage to the snail shell during the blocking process of the snail by the finger-shaped post 62, the finger-shaped post 62 of this embodiment is made of elastic materials, such as rubber and PU leather.

After the snails are reset, they can be sent to the cutting component for cutting. In order to remove the tail of snails with different tail orientations, the shearing assembly of this embodiment includes an upper shearing wheel 8 , a lower shearing wheel 9 and a pressure wheel 10 . Last shearing wheel 8 is rotated and installed in installation box 1, and is positioned at the top of conveyer belt 3 surfaces, and the gap of upper shearing wheel 8 and conveyer surface is less than the protruding height of snail tail. The lower cutting wheel 9 is rotatably installed in the installation box 1 and is located between the upper belt body and the lower belt body of the conveyor belt 3 . The gap between the lower shearing wheel 9 and the bottom of the through-type screw groove 7 positioned on the upper body is less than the protruding height of the snail tail. The upper shearing wheel 8 and the lower shearing wheel 9 are driven by a reduction motor. The pressure roller 10 is rotated and arranged above the surface of the conveyor, the vertical position of the pressure roller 10 is consistent with the vertical position of the lower shear wheel 9, and the gap between the pressure roller 10 and the conveyor is smaller than that in the through-type screw groove 7 The minimum height of the snail protruding. That is, the pressing wheel 10 can compress the snail whose tail is downward.

When the tail is removed, the snail is sent to the bottom of the pinch wheel 10 and is pressed by the pinch wheel 10, and the lower shearing wheel 9 cuts off the snail tail with the snail tail facing downward. When the upward snail tail was delivered to the upper shearing wheel 8 below, its tail was cut off by the upper shearing wheel 8 . When the upper shearing wheel 8 cuts off the tail of the snail with the tail facing upward, the interference between the tail of the snail and the upper shearing wheel 8 will make the snail obtain a pressure, so that it is firmly pressed in the through-type screw groove 7, Thereby realize the snail tail cut off.

Preferably, the surface of the pressure roller 10 is attached with an elastic layer made of soft elastic material, such as rubber or TPE material.

What is described above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise of not departing from the structure of the present invention, some deformations and improvements can also be made, and these will not affect the implementation of the present invention effect and utility of the patent.
