DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0048] See also Figures 1 to 8 In an embodiment of the present invention, a fish dry-curing device based on automatic high-uniform salting includes: a frame structure 1, a bottom plate 5, a sliding sleeve 16 and a retaining assembly, so that during the reciprocating motion of the loosening rod 17, grooves at different positions can be drawn on the salt, and the number of grooves is twice the number of the loosening rods 17, so that the salt can be dispersed faster in the hopper 3 and the dispersion effect is better, ensuring that the salt can be evenly spread on the fish during salting, thereby improving the curing effect.

[0049] The frame structure 1 is provided with a hopper 3, and the two are connected via a high-frequency vibration generator 2;

[0050] The bottom plate 5 is slidably fitted with the bottom of the hopper 3, and a conducting hole 501 is provided on the bottom plate 5, and the conducting hole 501 is adapted to the material hole 301 provided at the bottom of the hopper 3, and can control the conduction state of the material hole 301. Specifically, a limiting guide plate 4 is provided on the side of the hopper 3, and the limiting guide plate 4 is slidably connected with the bottom plate 5;

[0051] The hopper 3 is connected to the bottom plate 5 via a pushing structure, and the pushing structure includes a No. 1 electric telescopic rod 6 fixedly connected to the hopper 3, and a No. 1 groove wheel 7 is rotatably mounted on the telescopic end of the No. 1 electric telescopic rod 6;

[0052] The pushing structure also includes a driving plate 8 fixedly connected to the bottom plate 5, and a guide groove is provided on the driving plate 8. The No. 1 groove wheel 7 can roll in the guide groove, and the guide groove includes an inclined groove 801 provided on the driving plate 8, and each of the two ends of the inclined groove 801 is connected to a vertical groove 802, and the length direction of the vertical groove 802 is perpendicular to the upper end surface of the bottom plate 5.

[0053] Under the guidance of the limiting guide plate 4, the bottom plate 5 can move along the length direction of the hopper 3, so that the conducting hole 501 and the material hole 301 are overlapped or misaligned. In detail, when the conducting hole 501 and the material hole 301 are overlapped, the material hole 301 is in a conducting state. At this time, the salt in the hopper 3 can be scattered onto the fish through the material hole 301 and the conducting hole 501, so as to be marinated. When the conducting hole 501 and the material hole 301 are misaligned, the material hole 301 is in a blocked state, so as to prevent the salt in the hopper 3 from spilling.

[0054] In detail, in the initial state, the material hole 301 is in a blocked state, that is, the conductive hole 501 is in a misaligned state with the material hole 301. At this time, the salt can be poured into the hopper 3, and the high-frequency vibration generator 2 is used to vibrate the hopper 3, so that the salt can be distributed more evenly in the hopper 3, so that during the pickling process, the salt can be evenly distributed on the fish, thereby improving the pickling effect.

[0055] In the initial state, the No. 1 sheave 7 is in the vertical groove 802 at the upper part of the inclined groove 801. When the salt is evenly distributed in the hopper 3, the No. 1 electric telescopic rod 6 can be controlled to work and drive the No. 1 sheave 7 to move vertically downward. During this process, the No. 1 sheave 7 cooperates with the inclined groove 801 to drive the bottom plate 5 to move relative to the hopper 3. When the No. 1 sheave 7 moves to the vertical groove 802 at the lower part of the inclined groove 801, the conducting hole 501 and the material hole 301 are in an overlapping state, so that the material hole 301 is conductive and the salt application action can be performed.

[0056] It should be noted that when the No. 1 groove wheel 7 is in the vertical groove 802, since the bottom plate 5 can only move in the horizontal direction, and the movement direction of the bottom plate 5 is always perpendicular to the length direction of the vertical groove 802, when the No. 1 groove wheel 7 enters the vertical groove 802, it has a locking effect on the bottom plate 5, thereby improving the stability of the bottom plate 5.

[0057] Through the above arrangement, when controlling the movement of the No. 1 electric telescopic rod 6, the No. 1 groove wheel 7 can cooperate with the inclined groove 801 to drive the bottom plate 5 to move relative to the hopper 3, and make the conducting hole 501 and the material hole 301 overlap or misalign, thereby changing the conduction state of the material hole 301, so that the material hole 301 can be opened or closed according to actual needs.

[0058] See also Figure 7-8 The sliding sleeve 16 is connected to a driving assembly provided on the hopper 3, and the driving assembly can drive the sliding sleeve 16 to reciprocate along the length direction of the hopper 3;

[0059] The loosening rods 17 are provided in multiple groups and are arranged equidistantly along the length direction of the sliding sleeve 16;

[0060] The driving assembly includes a support frame 9 detachably mounted on the hopper 3, two sets of transmission wheels 11 are rotatably mounted on the support frame 9, a transmission belt 12 is sleeved between the two sets of transmission wheels 11, and a rotating shaft of one set of the transmission wheels 11 is connected to a No. 1 driving device 10 arranged on the support frame 9;

[0061] The driving assembly further includes a transverse frame 14 connected to the sliding sleeve 16. Specifically, the sliding sleeve 16 is slidably mounted on the transverse frame 14. The transverse frame 14 and the transmission belt 12 are connected via a chimeric structure. Two sets of guide members 15 are symmetrically arranged in the hopper 3. The sliding connection portion 1401 formed at the end of the transverse frame 14 can move along the length direction of the guide member 15.

[0062] The interlocking structure includes two protrusions 1402 arranged along the length direction of the transverse frame 14 , and an interlocking wheel 13 is rotatably mounted on the transmission belt 12 , and the interlocking wheel 13 can roll between the two protrusions 1402 .

[0063] When the salt is poured into the hopper 3, on the one hand, the high-frequency vibration generator 2 can drive the hopper 3 to vibrate, so that the salt in the hopper 3 generates high-frequency vibration, so that the salt can be evenly distributed in the hopper 3 (it takes a long time), and on the other hand, the No. 1 driving device 10 will work and make the transmission wheel 11 and the transmission belt 12 move. At this time, the interlocking wheel 13 will follow the movement of the transmission belt 12, wherein the transmission belt 12 can be regarded as consisting of two circular segments and two straight segments, so that the interlocking wheel 13 can cooperate with the protrusion 1402 when following the movement of the transmission belt 12, and drive the transverse frame 14 to reciprocate along the length direction of the guide member 15, so as to drive the loosening rod 17 to move along the length direction of the hopper 3. In this process, the salt can be divided into several grooves, which accelerates the dispersion effect of the salt in the hopper 3 and enables the salt to be quickly and evenly distributed in the hopper 3.

[0064] Through the above arrangement, when the high-frequency vibration generator 2 is working, the loosening rod 17 can move along the length direction of the hopper 3, so that the salt can be drawn into several grooves, so that the salt can be dispersed in the hopper 3 faster and with better dispersion effect, ensuring that the salt can be evenly spread on the fish when applying the salt, thereby improving the pickling effect.

[0065] See also Figure 5 , Figure 8 The retaining assembly is connected to the sliding sleeve 16, and the retaining assembly cooperates with the trigger member 30 provided on the hopper 3, so that the sliding sleeve 16 can move along the width direction of the hopper 3 when the sliding sleeve 16 moves to the end of the stroke;

[0066] The holding assembly includes a connecting frame 21 slidably connected to the transverse frame 14. Specifically, the connecting frame 21 is slidably arranged through the transverse frame 14, a second groove wheel 20 is rotatably mounted on the connecting frame 21, and the connecting frame 21 is connected to the transverse frame 14 through a spring 22;

[0067] The retaining assembly further includes a stopper 19 disposed on the sliding sleeve 16, and the stopper 19 is in rolling cooperation with the second groove wheel 20;

[0068] The stopper 19 is symmetrically provided with two grooves 1901 on one side facing the second groove wheel 20, and an outer protrusion 1902 is formed in the middle of the two grooves 1901, and the second groove wheel 20 can switch between the two grooves 1901 through the outer protrusion 1902;

[0069] One end of the trigger member 30 is provided with an inclined guide surface, and the trigger wheel 18 symmetrically and rotationally mounted on the sliding sleeve plate 16 is adapted to the inclined guide surface.

[0070] In the initial state, the second groove wheel 20 is in one of the grooves 1901, and the spring 22 is in a stretched state. When the sliding sleeve 16 moves to the end of the stroke, one set of trigger wheels 18 will abut against the inclined guide surface on the trigger member 30. Then, under the trend of the inclined guide surface, the sliding sleeve 16 drives the limit member 19 to move along the length direction of the transverse frame 14. At this time, the second groove wheel 20 can be separated from the groove 1901, so that the spring 22 is further stretched and the second groove wheel 20 is moved toward the outer protrusion 19 02 movement, until the second groove wheel 20 moves past the outer protrusion 1902, the spring 22 will release the elastic potential energy and actively drive the sliding sleeve 16 to move, and then when the second groove wheel 20 moves to another groove 1901, the position of the loosening rod 17 changes, so that when the loosening rod 17 moves in the opposite direction, new grooves can be drawn on the salt, that is, in the process of the reciprocating motion of the loosening rod 17, grooves twice the number of the loosening rod 17 can be drawn on the salt, thereby further improving the dispersion effect of the salt in the hopper 3.

[0071] Preferably, the distance between the two grooves 1901 is half of the distance between two adjacent loosening rods 17, so that when the loosening rod 17 moves in the reverse direction, a new groove can be drawn between two adjacent grooves.

[0072] Through the above arrangement, during the reciprocating motion of the loosening rod 17, grooves at different positions can be drawn on the salt, and the number of grooves is twice the number of the loosening rods 17, which can further accelerate the speed of dispersing the salt in the hopper 3, thereby achieving the effect of making the salt dispersed more evenly in the hopper 3.

[0073] It is worth noting that the material hole 301 can be opened only after the salt is completely dispersed in the hopper 3.

[0074] See also Figure 1-2 A second clamping plate 25 is also rotatably mounted on the frame structure 1, and the rotating shaft of the second clamping plate 25 is connected to a second driving device 23 disposed on the frame structure 1;

[0075] The second clamping plate 25 is connected to a first clamping plate 24 parallel thereto, and the first clamping plate 24 and the second clamping plate 25 are connected by two sets of parallel connecting rods 27, one end of one set of the connecting rods 27 is provided with an extension part 28, and the extension part 28 is connected to a second electric telescopic rod 29 rotatably mounted on the first clamping plate 24;

[0076] The first splint 24 and the second splint 25 are provided with hollow parts 26 .

[0077] Since the No. 1 splint 24 and the No. 2 splint 25 are in a parallel state, the two connecting rods 27 are in a parallel state, so that the No. 1 splint 24, the No. 2 splint 25 and the two connecting rods 27 can form a parallelogram, and in the process of placing the fish body, the connecting rod 27 is in a vertical state, and at this time there is a larger distance between the No. 1 splint 24 and the No. 2 splint 25, so that it is convenient to take and place the fish body. After the fish body is placed, the No. 2 electric telescopic rod 29 is controlled to move, and at this time the connecting rod 27 can deflect, so that the No. 1 splint 24 and the No. 2 splint are in a parallel state. The distance between the clamps 25 is reduced, thereby achieving the clamping of the fish body. Subsequently, the material hole 301 is opened, and the salt contacts the fish body through the hollow part 26 to be partially pickled. After the pickling is completed, the No. 2 electric telescopic rod 29 moves in the opposite direction. At this time, the distance between the No. 1 clamp 24 and the No. 2 clamp 25 first increases and then decreases, and at the same time, the solid position between the two adjacent hollow parts 26 and the hollow part 26 are switched. At this time, salt can be sprinkled on the position on the fish body where no salt is sprinkled, thereby achieving the pickling of one side of the fish body.

[0078] Furthermore, after one side of the fish body is marinated, the second drive device 23 works and drives the first clamping plate 24 and the second clamping plate 25 to flip 180 degrees, and repeats the above steps to marinate the other side of the fish body, thereby achieving marination of the entire fish body and improving the uniformity of marination.

[0079] Through the above arrangement, on the one hand, the fish body can be clamped, thereby ensuring the stability of the fish body when the No. 1 clamping plate 24 and the No. 2 clamping plate 25 are turned over, so that both sides of the fish body can be pickled. On the other hand, the position switching between the No. 1 clamping plate 24 and the No. 2 clamping plate 25 can be achieved, so that the position on the fish body covered by the No. 1 clamping plate 24 or the No. 2 clamping plate 25 can be effectively pickled, thereby improving the uniformity of pickling.

[0080] As an embodiment of the present invention, a method for high-uniform salting using the fish dry-curing equipment based on automatic high-uniform salting is also proposed, comprising the following steps:

[0081] Step 1: pour a predetermined amount of salt into the hopper 3, and start the high-frequency vibration generator 2 and the driving assembly;

[0082] Step 2: The driving assembly drives the loosening rod 17 to move along the length direction of the hopper 3 to allocate the salt in the hopper 3;

[0083] Step 3: When the loosening rod 17 follows the driving assembly to move to the end of the stroke, the holding assembly cooperates with the trigger member 30 to make the sliding sleeve 16 move along the width direction of the hopper 3, and then the loosening rod 17 follows the driving assembly to move in the reverse direction;

[0084] Step 4: Place the fish body to be pickled between the No. 1 clamping plate 24 and the No. 2 clamping plate 25, and move the bottom plate 5 relative to the hopper 3 to make the material hole 301 conductive, so that the salt falls onto the No. 2 clamping plate 25 through the material hole 301 and contacts the fish body through the hollow portion 26, and then the No. 2 electric telescopic rod 29 moves to move the No. 2 clamping plate 25 relative to the No. 1 clamping plate 24, so that the originally covered area of ​​the fish body is pickled;

[0085] Step 5: The second driving device 23 works to turn over the first clamping plate 24 and the second clamping plate 25, and then repeat the above step 4 to marinate the other side of the fish body.
