Description

Technical Field

[0001] This utility model relates to the field of food processing equipment, specifically to a snail spiral section cutting machine. Background Technology

[0002] The preparation of snail rice noodles and snail and duck feet stew requires a large number of snails. When cooking snail-related dishes, the spiral part of the snail needs to be cut to remove its feces and internal organs. Most existing snail tail-cutting devices involve continuously rotating the snail in a drum, using gravity to cause it to fall into a circular hole, where blades on the outside of the drum cut the snail's tail. Because the rotation speed of the drum and the cutting force of the blades are constant and uncontrollable, the success rate of tail-cutting is unpredictable.

[0003] The inventor's previous Chinese patent application, "202222751232.3 Snail Cutting Machine," utilized the cooperation between a snail support groove and a snail tail hole, along with a cover plate for clamping, achieving a good cutting effect on the spiral part of the snail. However, after prolonged use, some problems were discovered, such as: the cover is a one-piece plate structure, the snail shell is slippery, resulting in poor clamping effect, and the snail easily flying out during cutting; and the hinge structure of the snail support, after long-term operation, suffers from poor engagement between the hinge and the snail support due to wear, leading to chain slippage during rotation. Therefore, further improvements are necessary. Summary of the Invention

[0004] This utility model aims to provide a snail spiral section cutting machine. The snail spiral section cutting machine has a scientific and reasonable structural design, a high success rate of tail cutting, a small size, low cost, and a more stable working process. It is especially suitable for restaurants, snail wholesale and retail outlets, snail breeding bases, etc. to cut the tails of snails.

[0005] The aforementioned snail spiral section cutting machine includes a housing, a snail support plate, a drive mechanism, and a tail-cutting mechanism; A drive shaft and a driven shaft are respectively arranged between the front and rear side walls inside the housing; the drive shaft and the driven shaft are arranged longitudinally at intervals, and a drive wheel and a driven wheel are respectively provided on them, and the drive wheel and the driven wheel can rotate based on the drive shaft and the driven shaft; multiple sets of screw support plates are provided, and the left and right parts of each set of screw support plates are hinged to form a surrounding belt structure, and the surrounding belt formed by each set of screw support plates is mounted around the drive wheel and the driven wheel; the drive shaft is connected to the drive mechanism; The snail support plate is provided with a snail support groove. When the snail support plate is located above the surrounding area, the snail support groove is an inverted frustum-shaped groove. The bottom opening diameter of the frustum-shaped groove is slightly larger than the diameter of the spiral part of the snail to be cut. When the snail is placed in the snail support groove, the tail of the snail extends out from the bottom of the snail support groove below the snail support plate. Each group of screw support plates has a rotating shaft seat on the top surface near the forward direction, and the cover plate shaft is installed on the rotating shaft seat; a cover plate is installed on the cover plate shaft, and the cover plate can rotate based on the cover plate shaft.

Several rubber bands B are provided on the top surface of the cover plate. The rubber bands B are arranged to cover the top of the snail pressing hole and are in a taut state. The sum of the thickness of the cover plate and the snail support plate is less than the height of the snail body's spiral layers. A tail-cutting mechanism is provided between the driving wheel and the driven wheel. The tail-cutting mechanism is set at the bottom of the snail support plate located above in the surrounding belt and is used to cut off the spiral part of the snail passing through it.

[0006] The bottom surface of the cover plate is a downward sloping surface along the forward direction, and the top surface of the screw support plate is an upward sloping surface along the forward direction. The inclination angles of these two sloping surfaces are the same.

[0007] The inclined plane has an angle of 5-10° relative to the horizontal plane.

The front end of connecting rod A is hinged to the preceding screw plate in the forward direction, the rear end of connecting rod A is hinged to the front end of connecting rod B, and the rear end of connecting rod B is hinged to the following screw plate. The sum of the lengths of connecting rod A and connecting rod B is greater than the distance between two adjacent screw plates, so that the hinge point of connecting rod A and connecting rod B protrudes upward when moving forward. A hook plate is provided on the rear end of connecting rod A. The rubber band A is a rubber ring structure. The rubber ring simultaneously wraps around and hooks the rear end of connecting rod A and two sets of pulling bolts, which are respectively limited by the hook plate and the bolt head of the pulling bolt. The lower middle part of the housing is provided with a tensioning and resetting mechanism, which includes a rotating arm, a resetting shaft, a resetting bearing, and a tension spring. There are two sets of rotating arms and tension springs.

The front ends of the two sets of rotating arms are also fixedly connected to one end of the tension spring, and the other end of the tension spring is installed on the front and rear side walls of the housing through the spring shaft. The reset bearing is mounted on the reset shaft and is located inside the movement trajectory of connecting rod A and connecting rod B. Under the action of the pull spring, it applies downward pressure to connecting rod A and connecting rod B, keeping the connection between connecting rod A and connecting rod B stable, while simultaneously tensioning the surrounding belt structure.

[0012] The tail-cutting mechanism includes a tail-cutting motor and a tail-cutting blade. The tail-cutting motor is installed inside the housing, and the output shaft of the tail-cutting motor is vertically upward, with a circular tail-cutting blade on it. A protective plate is provided above the tail-cutting blade.

[0013] The two ends of the driven shaft are respectively mounted on the front and rear side walls inside the housing via driven bearings and driven bearing seats, and the two ends of the driving shaft are respectively mounted on the front and rear side walls inside the housing via driving bearings and driving bearing seats. The driving wheels are provided in two sets, located on the front and rear sides of the driving shaft, and the driven wheels are provided in two sets, located on the front and rear sides of the driven shaft.

The driving mechanism is a drive motor, which is installed on the rear side inside the housing. Its output shaft is connected to the drive shaft, driving the drive wheel to rotate, which in turn drives the surrounding belt to rotate.

[0014] The bottom plate of the shell is provided with a discharge port at one end, and a guide plate is provided at the bottom of the shell. The guide plate is connected to the left side wall, front side wall and rear side wall of the shell respectively, and its end extends to the bottom of the discharge port. The guide plate is inclined downward in the direction of the discharge port.

[0015] The working process of this utility model is as follows: The drive motor is started, which drives the circular belt structure composed of various snail support plates to rotate in a cycle. At the same time, the tail-cutting motor is started, which drives the tail-cutting blade to rotate. The snails are manually placed into the slots on the left-side snail support plate. The bolt heads of the positioning bolt and the pulling bolt are pressed down by the cover mechanism, so that the cover plate is closed on the snail support plate. The protective rod prevents the cover plate from lifting during cutting, thus preventing the snails from leaving the cutting position. The snails advance to the tail-cutting blade and are cut off at the tail. Then they continue to advance and rotate downwards after reaching the right side. Under the action of their own weight and the pulling action of the rubber band A, combined with the inclined structure of the bottom surface of the cover plate, the cover plate opens, and the snails fall from the snail placement slots and are finally discharged from the snail outlet into the pre-placed container.

[0016] The beneficial effects of this utility model are as follows: This utility model, including a screw support base and cover plate, as well as screw grooves and screw pressing holes, combined with a linkage structure design such as rubber band B, can effectively achieve the fixed clamping of screws of different sizes.

[0017] This utility model, through its uniquely designed capping mechanism, can precisely fasten the cap onto the screw support, achieving the clamping effect of the screw support groove and screw pressing hole on the screw.

[0018] This utility model features a protective rod structure that effectively prevents the cover from opening abnormally during the snail cutting process, prevents splashing during snail tail trimming, and ensures the safety of operators.

[0019] This utility model features a protective plate for the tail-cutting mechanism, which effectively avoids potential safety hazards to operators caused by the tail-cutting blade during operation.

[0020] This utility model features a uniquely designed tensioning and reset mechanism that effectively prevents chain slippage caused by poor meshing between the sprocket and the screw support due to wear and tear during long-term operation.

[0021] This invention overcomes the shortcomings of existing technology, has a more scientific and reasonable structural design, a high success rate in tail trimming, a small equipment size, low cost, and a more stable working process. It is especially suitable for restaurants, snail wholesale and retail outlets, snail farming bases, and other places that need to trim the tails of snails. Attached Figure Description
