The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

A processing table 3 for pre-processing samples is rotatably connected, a linkage member 27 is plugged into the processing table 3 and is rotatably connected to the processing table 3, a knife disc 9 for chopping food is fixedly connected to one end of the lifting rod 8, a mixing member 10 for uniformly mixing the chopped food is arranged at the bottom of the knife disc 9, and the knife disc 9 is in a grid shape; a driving member 11 includes a linear drive 5 fixedly connected to the base 1, a mounting plate 6 is fixedly arranged at the movable end of the linear drive 5, a rotating motor 7 is fixedly connected to the mounting plate 6, an output pipe of the rotating motor 7 passes through the mounting plate 6, and is fixedly connected to the lifting rod 8;

[0037] A sampling slot 36 is provided at the bottom of the processing table 3, a moving slot 34 is provided at the top of the sampling slot 36, a baffle 33 is slidably inserted in the moving slot 34, three groups of moving slots 34 and baffles 33 are provided, evenly distributed at the bottom of the processing table 3, and the spacing between the three groups of moving slots 34 and baffles 33 is the same as the spacing between the three groups of linkage members 27;

[0038] The mixing element 10 includes a connecting rod 101 plugged into the bottom end of the blade disc 9, one end of the connecting rod 101 is fixedly connected to a connecting column 102, a rotating rod 105 is provided at the side end of the connecting column 102, three groups of rotating rods 105 are provided, and the spacing between the three groups of rotating rods 105 is the same as the spacing between the three groups of baffles 33, the bottom end of the rotating rod 105 and the top of the baffle 33 are both embedded with magnets, and the magnetic poles of the two magnets are opposite, so that the bottom end of the rotating rod 105 is magnetically connected to the top of the baffle 33.

[0039] When the rotating rod 105 rotates with the lifting rod 8, it abuts against the linkage member 27 and drives it to rotate, so that the collecting member 22 on the rotating disk 2 moves to the discharge hole of the sampling slot 36. At the same time, under the action of centrifugal force, the rotating rod 105 flips ninety degrees and pushes the baffle 33 to move into the moving slot 34.

[0040] For this purpose, in the present technical solution, the linear drive 5 adopts the existing technology, which is composed of a motor, a screw, a guide rail, a transmission part and a control system. The screw is driven to rotate by the motor, and the screw is connected to the slider on the guide rail. When the screw rotates, the slider produces a linear motion along the guide rail.

[0041] Reference Fig. 9The side end of the connecting column 102 is provided with a receiving groove 103, and the receiving grooves 103 are arranged in three groups and are evenly distributed on the side end of the connecting column 102. A group of connecting ears 104 are fixedly connected in each group of receiving grooves 103, and a rotating rod 105 is arranged on the connecting ear 104. The rotating rod 105 consists of an outer rod 1051, a middle rod 1052 and an inner rod 1053. The middle rod 1052 is slidably plugged with the outer rod 1051, and the inner rod 1053 is slidably plugged with the middle rod 1052. The outer rod 1051 is hinged with the connecting ear 104. Springs 26 are fixedly arranged between the opposite ends of the middle rod 1052 and the outer rod 1051 and between the opposite ends of the inner rod 1053 and the middle rod 1052, so that there is an elastic tension between the middle rod 1052 and the outer rod 1051 and between the inner rod 1053 and the middle rod 1052. When the spring 26 is at its original length, the outer rod 1051 is located inside the middle rod 1052, and the inner rod 1053 is located inside the middle rod 1052. The elastic tension between the rotating rods 105 is less than the centrifugal force exerted on the rotating rod 105. When the connecting column 102 rotates, affected by the centrifugal force, the middle rod 1052 slides out of the outer rod 1051, and the inner rod 1053 slides out of the middle rod 1052, stirring and mixing the chopped food. When the connecting column 102 moves downward, the rotating rod 105 abuts against the processing table 3, and when subjected to the force exerted by the abutment, it rotates upward around the connecting ear 104. At this time, due to the influence of gravity and the elastic tension, the middle rod 1052 retracts into the outer rod 1051, and the inner rod 1053 retracts into the middle rod 1052, so that the rotating rod 105 is received in the receiving groove 103.

[0042] The above scheme is adopted: through the design of three groups of receiving grooves 103 and connecting ears 104, the rotating rod 105 can effectively stir and mix the chopped food under the action of centrifugal force to ensure uniformity, and the elastic tension design enables the middle rod 1052 and the inner rod 1053 to retract flexibly, thereby ensuring the stability of the rotating rod 105 during movement and avoiding uneven mixing. When the connecting column 102 rotates or moves downward, the rotating rod 105 can automatically retract into the receiving groove 103, thereby improving the operational safety and efficiency of the equipment.

[0043] Reference Figures 7 and 8The linkage member 27 includes a plug plate 23 fixedly connected to the top of the rotating disk 2, a cavity 24 is provided at the side end of the plug plate 23, a stopper 25 is inserted in the cavity 24, the top of the stopper 25 is an inclined surface, one end of the stopper 25 is fixedly connected to a spring 26, one end of the spring 26 is fixedly connected to the inner wall of the cavity 24, multiple groups of springs 26 are arranged, evenly distributed at one end of the stopper 25, the plug plate 23 is plugged into the processing table 3 and is rotatably connected to the processing table 3, the stopper 25 passes through the processing table 3 and is rotatably connected to the processing table 3, the collecting member 22 includes a fixing frame 221 plugged into the rotating disk 2, a collecting box 222 is clamped at the top of the fixing frame 221, and a side end of the fixing frame 221 A taking groove 223 is provided, a rotating groove 31 is provided at the bottom of the processing table 3, and the rotating groove 31 runs through the inner wall of the processing table 3, the insert plate 23 is rotatably plugged into the rotating groove 31, the stopper 25 is arranged in the rotating groove 31, and one end of the rotating groove 31 passes through the rotating groove 31, when the knife disc 9 moves down to cut the food in the processing table 3, it abuts against the inclined surface of the stopper 25, so that the stopper 25 is pressed into the cavity 24, when the knife disc 9 leaves the processing table 3, the stopper 25 is reset under the action of the spring 26, and when the rotating rod 105 rotates, it abuts against the stopper 25, driving the linkage member 27 to rotate in the rotating groove 31, and driving the collecting member 22 on the rotating disk 2 to rotate synchronously.

[0044] The above scheme is adopted: the plug plate 23 is plugged and rotatably connected to the processing table 3, and the stop block 25 passes through the processing table 3, ensuring the stable connection between the linkage member 27 and the processing table 3, so that it is not easy to loosen or error during operation. The stop block 25 can achieve precise abutment and linkage with the rotating rod 105 through the rotating groove 31. When the rotating rod 105 rotates, the stop block 25 drives the linkage member 27 to rotate synchronously in the rotating groove 31, ensuring the coordinated operation of the entire system.

[0045] Reference Figures 4 to 6 The sampling trough 36 includes a feed trough 32, a connecting trough 35 and a feeding trough 38, wherein the top of the connecting trough 35 is connected to the feed trough 32, and the bottom of the connecting trough 35 is connected to the bottom of the feeding trough 38. There are three groups of feed troughs 32, and the bottom of the processing table 3 is evenly opened. The spacing between the three groups of feed troughs 32 is the same as that of the three groups of collecting parts 22. The cross-section of the connecting trough 35 is an inverted trapezoid, and the connecting trough 35 is an annular groove, and the feeding trough 38 is spiral.

[0046] The above scheme is adopted: the three groups of feeding chutes 32 evenly distributed at the bottom of the processing table 3 can effectively guide the food fragments into the processing table 3, ensuring the uniform distribution of the food fragments and providing a stable basis for subsequent processing. The inverted trapezoidal cross-section and the annular groove structure of the connecting groove 35 can effectively gather the scattered food fragments, avoiding the dispersion of the food fragments and ensuring the accuracy and consistency of sampling. The gathered food fragments can be efficiently discharged from the processing table 3 through the spiral feeding trough 38, which can effectively utilize the space and transport the food fragments from the inside of the processing table 3 to the output end of the equipment, thereby improving the overall work efficiency.

[0047] Reference Fig.11 The top of the processing table 3 is fixedly connected to a support plate 37. Three groups of support plates 37 are arranged, which are evenly distributed on the top of the processing table 3. A top drop plate 4 for pushing down the food stuck in the knife disc 9 is rotatably connected to the support plate 37. The top drop plate 4 is located at the upper end of the knife disc 9. The lifting rod 8 passes through the top drop plate 4 and is fixedly connected to the knife disc 9. The lifting rod 8 is clamped with the top drop plate 4. When the knife disc 9 moves up, it is plugged into the top drop plate 4, so that the food stuck in the knife disc 9 is pushed out and falls into the processing table 3.

[0048] By adopting the above scheme, the food stuck in the knife disc 9 can be effectively ejected through the push-down plate 4, ensuring that the food falls smoothly into the processing table 3, thereby improving the processing efficiency. The stability of the push-down plate 4 above the knife disc 9 is ensured by the rotational connection with the support plate 37 and the clamping connection with the lifting rod 8, thereby avoiding displacement or loosening during operation.

[0049] The working principle of the present invention is as follows: when in use, the blade disc 9 is first lifted by the linear drive 5, and then the food is placed in the processing table 3, and then the blade disc 9 is moved down by the linear drive 5 to cut the food, and then the blade disc 9 is lifted again, and the top drop plate 4 is inserted into the blade disc 9, and the food stuck in the blade disc 9 is dropped into the processing table 3, and then the blade disc 9 and the top drop plate 4 are rotated by the rotating motor 7, and the cutting point is changed to cut the food again until the food becomes the required size, and then the blade disc 9 is continued to be controlled to rise, and the top drop plate 4 is inserted into the blade disc 9. At this time, the mixing element 10 rises accordingly, and the rotating rod 105 rotates ninety degrees under the action of gravity, and then the rotating motor 7 drives the rotating rod 105 to rotate clockwise. When the rotating rod 105 rotates, it is affected by the centrifugal force, and the middle rod 1052 slides out of the outer rod 1051, and the inner rod 1053 slides out of the middle rod 1052, so that the food in the processing table 3 is crushed. When the rotating rod 105 moves to the top of the baffle plate 33, the baffle plate 33 is driven to move in the moving groove 34 under the action of magnetism, so that the material drop groove 32 is exposed, and the food fragments are pushed into the material drop groove 32 under the thrust of the rotating rod 105. At this time, the rotating motor 7 stops working and the rotating rod 105 no longer moves. Since the distance between the collecting member 22, the linkage member 27 and the material drop groove 32 is the same, when the rotating rod 105 stops moving on the material drop groove 32, the collecting member 22 moves to the discharge port of the sampling groove 36, and the food fragments falling into the material drop groove 32 pass through the connecting groove 35 and fall into the sampling groove 36, and slide into the collecting box 222 under the action of the slope of the spiral of the sampling groove 36;The plug plate 23 is firmly plugged and rotatably connected to the processing table 3. At the same time, the design of the rotating groove 31 and the stop block 25 ensures stable rotation during the food processing process, thereby improving the reliability and operating efficiency of the equipment. The abutment between the rotating rod 105 and the stop block 25 enables the linkage member 27 to accurately follow the movement of the rotating rod 105 in the rotating groove 31, thereby driving the collecting member 22 on the rotating disk 2 to rotate synchronously, effectively cooperating with the operation of the entire system. Multiple groups of springs 26 are evenly distributed at one end of the stop block 25, ensuring that the stop block 25 can respond quickly and remain stable when abutted by the inclined surface of the knife disc 9, thereby enhancing the interactive effect between the processing table 3 and the knife disc 9. Through the components such as the sampling groove 36, the moving groove 34 and the baffle plate 33 inside the processing table 3, combined with the design of the blanking groove 32 and the connecting groove 35, A complete food processing and sampling system is formed, which can effectively manage and process food fragments, improve the efficiency and controllability of the operation, and effectively push the mixed food fragments from the mixing element 10 to the sampling trough 36 through the coordinated movement of the moving trough 34 and the baffle 33, and then discharge them through the spiral feeding trough 38, which optimizes the process and efficiency of food processing. The food fragments are mixed and stirred through the connecting rod 101, the connecting column 102 and the rotating rod 105, etc., to ensure the uniformity and consistency of the food after full mixing. The rotating rod 105 automatically contacts the processing table 3 and the linkage 27 with the movement of the lifting rod 8, and pushes the movement of the baffle 33 through the magnetic connection, so as to realize the precise processing and sampling process of the food fragments, and improve the intelligence and accuracy of the operation. ;

[0050] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.
