[0008] As a further improvement of the present invention, the blades are arc-shaped.

[0009] As a further improvement of the utility model, the crushing structure includes a transversely arranged rotating shaft, which is rotatably connected to the crushing chamber, and a plurality of crushing wheels are connected to the rotating shaft, and each crushing wheel is arranged at intervals along the length direction of the rotating shaft; the rotating shaft is linked to a rotating motor, and the rotating motor is installed on the box body.

[0013] Beneficial Effects

[0014] Compared with the prior art, the advantages of the food crushing sampler for food testing of the utility model are:

[0015] 1. After the food is placed at the feeding port, the food is first cut into multiple flake structures by the food slicing structure. When the flake food falls into the crushing chamber and is squeezed and crushed by the crushing roller, the load of the crushing roller can be reduced and the life of the equipment can be extended. The crushed material falls on the filter below. If the food particles are still not large enough to pass through the filter, they will be lifted up by the rotating blades in the material lifting structure and move upward. The lifted food particles will fall back between the two crushing rollers and be crushed again until the food particles are small enough to pass through the filter. This structure ensures that the food particles entering the crushing chamber are of basically the same size.

[0016] 2. After the food particles enter the crushing chamber, they are further crushed by the crushing wheel. When the pull-out baffle plate is placed above the sample grid, it prevents the food particles from falling, which can extend the crushing time of the crushing wheel on the food particles and allow the food to be fully crushed. After the crushing is completed, pull open the pull-out baffle plate, and the food particles fall into the pull-out sample box. Pull it out to collect the crushed and evenly mixed food samples.

[0017] 3. The blades are arc-shaped. When the blades scrape up the food particles at the bottom of the crushing chamber, the probability of the food particles sliding off the back side of the blades can be reduced, so that the food particles will fall only when they reach the top of the crushing roller with the blades.

[0018] 4. The filter is set on the pull-out plate, and the pull-out plate is connected to a vibrator. The vibration of the vibrator can reduce the accumulation of food particles on the filter and speed up the speed of food particles passing through the filter. Pulling out the pull-out plate can facilitate the replacement or cleaning of the filter.

[0019] The present invention will become more clear through the following description in conjunction with the accompanying drawings, which are used to explain the embodiments of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0024] Example

[0025] The specific implementation of the utility model is as follows Figure 1 to Figure 2 As shown, a food crushing sampling machine for food testing includes a box body 1, in which a feeding port 11, a crushing chamber 12, a crushing chamber 13 and a sample grid 14 are connected in sequence from top to bottom. A food slicing structure 2 is provided at the feeding port 11, and two crushing rollers 3 arranged in parallel are provided in the crushing chamber 12. The crushing rollers 3 are linked to a crushing roller driving device 5, and the crushing roller driving device 5 is specifically a motor. The vertical cross-section of the crushing chamber 12 is basically circular, and a material lifting structure 4 is also rotatably connected in the crushing chamber 12. A filter screen 6 is provided between the crushing chamber 12 and the crushing chamber 13, and a crushing structure 7 is provided in the crushing chamber 13.

[0026] The cross section of the feeding port 11 in the vertical direction is trapezoidal, and the food slicing structure 2 includes a swing arm 21, and a blade assembly 22 is connected to the swing arm 21. The blade assembly 22 is provided with at least two parallel and spaced blades, and the blades are sharpened on the edges of the blades except for the portion connected to the swing arm 21. One end of the swing arm 21 is hinged to the edge of the feeding port 11, and the other end is a free end, and the blade assembly 22 is adapted to the inner cavity of the feeding port 11.

[0027] The discharge port 11 includes a fixed inclined plate 111, two side plates 113 and a movable inclined plate 112. The fixed inclined plate 111 and the movable inclined plate 112 are arranged opposite to each other, the fixed inclined plate 111 is connected to the side plates 113, and the upper ends of the movable inclined plate 112 are hinged to the side plates 113 on both sides. A fixed seat 102 is provided on the box body 1, and a push rod 101 is movably connected to the fixed seat 102, and one end of the push rod 101 is pressed against the outer side surface of the movable inclined plate 112. Specifically, the middle part of the push rod 101 is connected to the fixed seat 102 by a threaded connection or a rotating clamp. Among them, one end of the swing arm 21 is hinged to the upper end of the fixed inclined plate 111 of the discharge port 11. When the food is just placed on the discharge port 11, in order to facilitate cutting, the distance between the fixed inclined plates 111 and the fixed inclined plates 111 is gradually reduced from top to bottom, specifically by the push rod 101 pressing against the outer side surface of the movable inclined plate 112. As Figure 1 As shown, by pressing the swing arm 21 counterclockwise downward, the blade assembly 22 enters the feeding port 11 to slice the food. After slicing, in order to facilitate the falling of the flaky food, the end of the push rod 101 is kept away from the outer side of the movable inclined plate 112, and the movable inclined plate 112 sags under the combined action of its own weight and the weight of the food, and the flaky food falls by itself and enters the crushing chamber 12.

[0028] The material lifting structure 4 includes a vertically arranged rotating ring 41, which is in the shape of a circular ring. The outer wall of the rotating ring 41 rotates with the inner wall of the circular crushing chamber 12 of the box body 1, and a plurality of blades 42 are connected to the rotating ring 41 around its rotation axis. The two crushing rollers 3 are both located in the middle of the rotating ring 41, and the crushing rollers 3 are rotatably connected to the box body 1. The material lifting structure 4 also includes a rotating drive motor 43, which is installed outside the box body 1, and the output end of the rotating drive motor 43 is connected to a driving gear 44, and the rotating ring 41 is provided with a rack 45 meshing with the driving gear 44. By sequentially linking the rotating drive motor 43, the driving gear 44, the rack 45 and the rotating ring 41, the blades 42 on the rotating ring 41 can be driven to rotate around the rotation center of the rotating ring 41, so that the food particles that are not completely crushed and fall on the filter screen 6 are lifted up again, so that the food particles are crushed again by the rotating crushing rollers 3.

[0029] The blade 42 is arc-shaped, and the concave surface of the blade 42 faces forward in the rotation direction.

[0030] The crushing structure 7 includes a transversely arranged rotating shaft 71, which is rotatably connected to the crushing chamber 13, and a plurality of crushing wheels 72 are connected to the rotating shaft 71, and each crushing wheel 72 is arranged at intervals along the length direction of the rotating shaft 71. The rotating shaft 71 is linked to a rotating motor 73, and the rotating motor 73 is installed on the box body 1. The crushing wheels 72 further crush the food particles in the crushing chamber 13 by rotating at a high speed, and stir and mix them at the same time.

[0031] The filter 6 is arranged on a horizontally withdrawable pull-out plate 16, and the pull-out plate 16 is connected to a vibrator 8. The pull-out plate 16 is slidably connected transversely relative to the housing 1. The vibration of the vibrator 8 can reduce the accumulation of food particles above the filter 6, and speed up the speed at which food particles pass through the filter 6. By withdrawing the pull-out plate 16, the filter can be easily replaced or cleaned.

[0032] A pull-out baffle plate 15 is provided between the crushing chamber 13 and the sample grid 14, and the pull-out baffle plate 15 is slidably connected to the box body 1 in a transverse direction. A pull-out sample box 9 is provided in the sample grid 14, and a sample receiving port is provided at the top of the pull-out sample box 9. When the pull-out baffle plate 15 is placed above the sample grid 14, food particles are prevented from falling, and the crushing time of the crushing wheel 72 for food particles can be extended, so that the food can be fully crushed. After the crushing is completed, the pull-out baffle plate 15 is pulled open, and the food particles fall into the pull-out sample box 9, which can be pulled out to collect the crushed and evenly mixed food samples.
