Description

Technical Field

[0001] The utility model relates to the technical field of tender gorgon fruit shelling, in particular to a tender gorgon fruit shelling knife group and tender gorgon fruit shelling automation equipment. Background Art

[0002] Gorgon fruit is an annual aquatic herb. Because the receptacle and the bracts resemble a chicken's head, Gorgon fruit is also called chicken head rice. Gorgon fruit is a precious economic crop that can be used as both medicine and food.

[0003] Gorgon fruit is divided into southern and northern Gorgon fruit. Southern Gorgon fruit mainly harvests tender Gorgon fruit, while northern Gorgon fruit mainly harvests old Gorgon fruit. If southern Gorgon fruit is not harvested in time, it will also become old Gorgon fruit. Old Gorgon fruit is generally shelled with a conventional Gorgon fruit shelling machine, which is more efficient, but the peeled old Gorgon fruit pulp has low economic value. However, using a conventional Gorgon fruit shelling machine to shell tender Gorgon fruit, it is impossible to obtain intact pulp. The shelling problem of tender Gorgon fruit has become a major problem affecting its deep processing and widespread promotion for household consumption.

[0004] The main reasons why the tender gorgon fruit cannot be shelled by using a conventional gorgon fruit shelling machine are:

[0005] 1. The flesh of young water chestnut is delicate and easily bursts and breaks under the action of external force.

[0006] 2. Compared with the flesh, the shell of tender water chestnut is harder and not easy to be destroyed.

[0007] 3. Conventional water chestnut shelling machines will squeeze, vibrate or cut the water chestnuts with great force when shelling, which can easily damage the flesh.

[0008] Therefore, the existing shelling machine cannot realize the shelling operation of tender water chestnut.

[0009] In order to avoid damaging the flesh of the gorgon fruit and maintain the economic value of the tender gorgon fruit, the gorgon fruit shelling still has to be done manually by farmers. Manual peeling generally involves putting an iron nail (finger sheath) on the thumb and then operating the iron nail to peel the gorgon fruit from the top. If the farmer is unskilled or distracted, the flesh of the gorgon fruit may stick to the shell and be peeled off together.

[0010] Manual peeling is inefficient. Generally, manual peeling for eight hours a day can peel about 2-3 kg. For Gorgon fruit farmers, due to the low efficiency of peeling tender Gorgon fruit, they can only watch the tender Gorgon fruit that cannot be peeled become old Gorgon fruit, and the tender Gorgon fruit with high economic value becomes old Gorgon fruit with low economic value. For farmers, this is a huge economic loss. For consumers, the stock of tender Gorgon fruit on the market is small, which is far from meeting people's consumption demand for tender Gorgon fruit.

[0011] At the same time, it is difficult to ensure food hygiene when peeling by hand. During the processing, human hands, tools, and environment may cause contamination to the water chestnuts, seriously affecting the quality of the water chestnuts.

[0012] In view of this, solving the problem that the existing conventional water chestnut shelling machine cannot perform the tender water chestnut shelling operation and solving the problem that manual shelling is inefficient and easily causes food contamination have become the topics to be studied and solved by the utility model.

[0017] The knife holder is fixedly arranged at the bottom of each of the upright posts, and the knife holder has a knife groove for installing a cutting knife;

[0018] The cutter is mounted on the knife groove of the knife holder, the blade of the cutter is arranged to face upward, the tip of the cutter extends a distance toward the inside of the cavity, the three-dimensional inclination of one of the cutters is configured such that the cutter is inclined at an angle a around the X axis, an angle b around the Y axis, and an angle c around the Z axis in the XYZ coordinate system, wherein the angle a is the upward inclination of the cutter toward the inside of the cavity, and the other cutters are evenly distributed and arranged on the knife holder in the same three-dimensional inclination array around the center of the circle, and each cutter is suspended at the bottom of the column;

[0019] The floating mechanism is a mechanism that allows the size of the cavity to adapt to the outer diameter of the tender water chestnut. The floating mechanism is correspondingly arranged on the outside of the column. The floating mechanism includes a fixed part and a floating part.

[0021] The relevant contents of this utility model are explained as follows:

[0022] 1. In the above technical scheme of the utility model, in view of the problem that the existing conventional water chestnut shelling machine cannot perform the shelling operation of tender water chestnuts and the manual shelling is inefficient and easy to cause food contamination, a knife group and automated equipment that can be used for the shelling operation of tender water chestnuts are studied and designed. In the knife group, the floating mechanism enables the column and the cutter to be set in a floating manner, so that the cavity with a large top and a small bottom also changes with the change of the particle size of the tender water chestnuts, so that the knife group can adapt to tender water chestnuts of various particle sizes, without the need for pre-screening of particle sizes and configuring knife groups of various specifications, saving a lot of process costs and knife group preparation costs. In the knife group, the inner side of the column is arc-shaped, and the combination of multiple columns forms a conical cavity, so that the tender water chestnuts are not easy to be distorted during the movement from top to bottom, so as to avoid the distorted tender water chestnuts being cut off by the cutter, thereby avoiding the situation of damaging the flesh and peeling poorly. In the utility model, under the premise of the floating setting of the cutter, the cutter is designed to be three-dimensionally inclined, that is, the blade of the cutter is inclined in three dimensions. The design of the angle c inclined around the Z axis allows the cutter to deviate from the center of the circle, so that when the tender water chestnut is peeled, the cutter can not only cut deeply obliquely, but also ensure that the flesh is not damaged when the shell is cut off; the design of the inclination angle b around the Y axis, when the tender water chestnut is pressed downward into the cavity, under the action of the inclination angle b of the cutter, the shell of the tender water chestnut will be separated outward along the inclined direction after being peeled, so as to better achieve the separation of the water chestnut meat and the shell; the design of the inclination angle a around the X axis, and the angle a is the direction of the cutter facing the cavity The inner direction is tilted upward, so that after the cutter peels off the outer shell of the tender water chestnut, the shell is less likely to stick to the blade, the outer shell can be more easily separated from the blade, and the peeled water chestnut flesh no longer contacts the cutter, thereby preventing the cutter from damaging the flesh; and the cutter is tilted in three dimensions according to the scheme of the utility model, so that the tender water chestnut can rotate in the opposite direction of the tilt angle b around the Y axis during the process of being pressed down, because the tender water chestnut rotates during the peeling process, and the shape of the cut outer shell is arc-shaped. After the outer shell of the tender water chestnut is cut, it is peeled off by the cutter and away from the blade head as the tender water chestnut rotates, so it is easier to peel and will not damage the flesh inside.

The above distance size setting is the preferred solution of the utility model, which can further optimize the shelling effect and efficiency of the tender water chestnut shelling knife group.

[0026] 5. In the technical solution of the first aspect, the distance d is 1.2 mm; the distance e is 3 mm; the height f is 6 mm; the upper diameter of the cavity is 13 mm, and the lower diameter of the cavity is 6 mm. The above distance size settings are further preferred solutions of the utility model, which can further improve the shelling effect and efficiency of the tender water chestnut shelling knife set.

[0027] 6. In the technical solution of the first aspect, the cutter is provided with a breaking line for breaking and changing the cutter. This allows the cutter head to be directly broken off when the cutter blade becomes blunt after being used for a period of time, and the remaining cutter can be pushed inward a set distance, thereby facilitating maintenance and reducing the time for changing the cutter.

[0028] 7. In the technical solution of the first aspect, the knife holder is fixed at the bottom of the column, and the knife groove on the knife holder is configured to be consistent with the three-dimensional inclination of the cutter. In this way, the cutter only needs to place the blade in the knife groove, and no additional adjustment of the cutter is required. Its three-dimensional inclination is consistent with the inclination of the knife groove, and no angle adjustment is required.

[0029] 8. In the technical solution of the first aspect, the number of the columns is 3, and the cross-section of the columns is a sector-shaped circular ring. The use of columns with this structure is convenient for design, production, installation and positioning, ensuring that the gorgon fruit will not deviate when pressed down. The utility model is not limited to this, and the number of columns can also be 4, 5, 6, etc., and can be arranged as needed.

[0030] 9. In the technical solution of the first aspect above, the floating part in the floating mechanism includes an elastic member that provides an elastic force, and the elastic force of the elastic member is configured to be adjustable. This is to prevent the floating mechanism from applying too tight or too loose force to the column and the cutter during use, and to adjust the elastic force so that the elastic member always maintains a good floating effect. As for the arrangement of the elastic member in the floating mechanism, the elastic member can be a spring, which is sleeved on a threaded guide rod fixed to the column, and the fixed part can be a spring box. A nut that can adjust the spring travel can be set on the guide rod, and opposite action surfaces are set on the spring box and the guide rod connected to the column. Then, the spring is sleeved on the guide rod and acts on the action surface to realize the floating effect of the floating mechanism.

[0031] 10. In the technical solution of the first aspect above, the tip of the cutter is similar to a utility knife, and the tip is set at an inclined angle of 30° to 60° to ensure that the peeled Euryale ferox meat does not touch the cutter when moving downward.

Embodiment 1

[0066] As attached Figure 1 As shown, the first embodiment of the utility model discloses a tender water chestnut shelling knife group, which is used for the automatic shelling operation of tender water chestnuts 9. The tender water chestnut shelling knife group includes a column 1, a knife holder 2, a cutting knife 3, and a floating mechanism 4;

[0067] The number of the pillars 1 is greater than or equal to three, and the plurality of pillars 1 are evenly distributed around the center of the circle and enclose a cavity 10 that is larger at the top and smaller at the bottom for the tender water chestnut 9 to pass through, and the cavity 10 has a central axis that is consistent with the center line of the inscribed arc of the pillars 1 from top to bottom, and the direction of the central axis is defined as the Z axis, then the plane perpendicular to the Z axis is the XY plane, and the XY plane has an X axis and a Y axis, the Y axis passes through the midpoint of the inscribed arc of one of the pillars 1 on the XY plane and is perpendicular to the Z axis, and the X axis is perpendicular to the Y axis, thereby forming an XYZ coordinate system;

[0068] The tool holder 2 is fixedly arranged at the bottom of each of the columns 1, and the tool holder 2 has a knife groove 21 for installing a cutter 3; the cutter 3 is installed on the knife groove 21 of the tool holder 2, and the blade 31 of the cutter 3 is arranged to face upward, and the tip of the cutter 3 extends a distance toward the inside of the cavity 10, and the three-dimensional inclination of one of the cutters 3 is configured so that the cutter 3 is inclined at an angle a around the X axis, an angle b around the Y axis, and an angle c around the Z axis in the XYZ coordinate system, wherein the angle a is the upward inclination of the cutter 3 toward the inside of the cavity 10, and the other cutters 3 are evenly distributed on the tool holder 2 in the same three-dimensional inclination array around the center of the circle, and each cutter 3 is suspended at the bottom of the column 1;

[0069] The floating mechanism 4 is a mechanism that allows the size of the cavity 10 to adapt to the outer diameter of the tender water chestnut 9. The floating mechanism 4 is correspondingly arranged on the outer side of the column 1. The floating mechanism 4 includes a fixed part 41 and a floating part 42. The fixed part 41 is positioned and connected to the frame of an external tender water chestnut shelling automation equipment. One end of the floating part 42 is connected to the fixed part 41, and the other end is connected to the column 1. The floating forces the column 1 and the cutter 3 to always have a tendency to synchronously move toward the inside of the cavity 10.

[0070] In the first embodiment of the present utility model, the purpose of the utility model is achieved mainly through the following aspects.

[0071] Firstly, the floating mechanism 4 enables the column 1 and the cutting knife 3 to be floatingly arranged, so that the cavity 10 which is larger at the top and smaller at the bottom also changes with the change of the particle size of the tender water chestnut 9, so that the knife group can adapt to the tender water chestnut 9 of various particle sizes, without the need for pre-screening of particle sizes and configuration of knife groups of various specifications, thus saving a lot of process costs and knife group preparation costs.

[0072] Secondly, in the knife set, the inner side of the column 1 is arc-shaped, and the combination of multiple columns 1 forms a conical cavity 10, so that the tender water chestnut 9 is not easy to be distorted during the movement from top to bottom, so as to avoid the distorted tender water chestnut 9 being cut off by the cutting knife 3, thereby avoiding the situation of damaging the flesh and peeling properly.

[0073] Thirdly, under the premise of the floating setting of the cutter 3, the cutter 3 is designed to be three-dimensionally inclined, that is, the blade 31 of the cutter 3 is inclined in three dimensions. The design of the angle c inclined around the Z axis allows the cutter 3 to deviate from the center of the circle, so that when the tender water chestnut 9 is peeled, the cutter 3 can not only cut deeply obliquely, but also ensure that the flesh is not damaged when the shell is cut off; the design of the inclination angle b around the Y axis, when the tender water chestnut 9 is pressed downward toward the cavity 10, under the action of the inclination angle b of the cutter 3, the shell of the tender water chestnut 9 will be separated outward along the inclined direction after being peeled, thereby better realizing the separation of the water chestnut meat and the shell; the design of the inclination angle a around the X axis, and the angle a is the direction of the cutter 3 toward the cavity 10. 0 is tilted upward in the direction of the interior, so that after the cutter 3 peels off the outer shell of the tender water chestnut 9, the shell is less likely to stick to the blade, and the outer shell can be more easily separated from the blade 31, and the peeled water chestnut seeds no longer come into contact with the cutter 3, so as to avoid the cutter 3 damaging the flesh; and this cutter 3 is tilted in three dimensions according to the scheme of the utility model, so that the tender water chestnut 9 can produce a rotation in the opposite direction of the tilt angle b around the Y axis during the process of being pressed down, because the tender water chestnut 9 rotates during the shelling process, and the shape of the cut outer shell is arc-shaped. After the outer shell of the tender water chestnut 9 is cut, it is peeled off by the cutter 3 and away from the blade as the tender water chestnut 9 rotates, so it is easier to peel off without damaging the flesh inside. For the process of the cutter 3 peeling the tender water chestnut 9, please refer to Fig.10 and Fig.11 .

[0074] In the solution of the first embodiment of the present invention, the three-dimensional inclination of the cutter 3 is configured such that the cutter 3 is inclined at an angle a around the X axis, at an angle b around the Y axis, and at an angle c around the Z axis in the XYZ coordinate system. Figure 4 , Figure 5 , Figure 6 , Figure 7 ,like Figure 4 The cutter 3 shown in FIG. 1 is not tilted in three dimensions, wherein the Y axis is perpendicular to the Z axis and passes through the midpoint of the inscribed arc of one of the columns 1 on the XY plane, wherein the blade of the cutter 3 suspended at the bottom of the column 1 also extends along the Y axis; the next step, as Figure 5 The cutter 3 shown in the figure is in a state after being tilted at an angle a around the X-axis. At this time, the cutter 3 is tilted at 30° around the X-axis, and the cutter head is facing upwards. Figure 6 The cutter 3 is shown in the state after being tilted around the Y axis at an angle b. At this time, the cutter 3 is tilted around the Y axis by 30°. The last step is as follows: Figure 7 The cutter 3 is shown in a state after being tilted around the Z axis at an angle c, where the cutter 3 is tilted 30° around the Z axis. In this way, a three-dimensional tilt is formed, and the tool holder 2 is fixed in this three-dimensional tilt, so that the cutter 3 placed thereon can form a three-dimensional tilt without adjustment.

The above angles are set as the preferred scheme of the present invention, which can further optimize the shelling effect and efficiency of the tender water chestnut shelling knife group. Furthermore, the angle a is 30°; the angle b is 30°; the angle c is 30°. The above angles are set as the further preferred scheme of the present invention, which can further improve the shelling effect and efficiency of the tender water chestnut shelling knife group. The tip of the cutting knife is similar to that of a utility knife, and the tip is set at an inclined angle of 30°~60° to ensure that the peeled water chestnut meat does not touch the cutting knife when moving downward.

Furthermore, the distance d is 1.2 mm; the distance e is 3 mm; the height f is 6 mm; in the natural state, the upper diameter of the cavity 10 is 13 mm, and the lower diameter of the cavity 10 is 6 mm. The above distance size is set as a further preferred scheme of the present utility model, which can further improve the shelling effect and efficiency of the tender water chestnut shelling knife group.

[0077] In the solution of the first embodiment of the present utility model, Fig.12 As shown, the cutter 3 is provided with a breaking line 32 for breaking and changing the cutter. In this way, if the blade 31 of the cutter 3 is not sharp after being used for a period of time, the head of the cutter 3 can be directly broken, and the remaining cutter 3 can be pushed inward for a set distance, so as to facilitate maintenance and reduce the time for replacing the cutter 3.

[0078] In the solution of the first embodiment of the utility model, the knife holder 2 is fixed at the bottom of the column 1, and the knife groove 21 on the knife holder 2 is configured to be consistent with the three-dimensional inclination of the cutter 3. In this way, the cutter 3 only needs to place the blade in the knife groove 21, and there is no need to adjust the cutter 3. Its three-dimensional inclination is consistent with the inclination of the knife groove 21, and there is no need to adjust the angle.

[0079] In the solution of the first embodiment of the utility model, the number of the columns 1 is 3, and the cross-sectional shape of the columns 1 is a sector-shaped circular ring. The use of the columns 1 of this structure is convenient for design, production, installation and positioning, ensuring that the water chestnuts will not deviate when pressed down. The utility model is not limited to this, and the number of the columns 1 can also be 4, 5, 6, etc., and can be arranged as needed.
