On the rotating rod 3 is provided with a second one-way ratchet pawl (not shown in the figure) that cooperates with the second ratchet wheel 34. The output shaft of the driving member 1 is connected to one of the rotating shafts 4 on both sides through a first belt, and a second belt is provided between the rotating shafts 4 on the same side. The first belt drive and the second belt drive in the present utility model can both be replaced by a chain drive. The user should select a suitable drive method according to the actual situation. The addition of the drive gears involved in the chain drive and the installation method of the chain are both mature prior arts and will not be elaborated in this specification. When the driving member 1 rotates forward, the first ratchet wheel 43 and the first one-way ratchet pawl cooperate, the rotating shaft 4 drives the reciprocating lead screw 41 to rotate, the reciprocating lead screw 41 drives the threaded block 42 to reciprocate, the second ratchet wheel 34 and the second one-way ratchet pawl do not cooperate, that is, the rotating rod 3 does not drive the reciprocating rod 31 to rotate, and the reciprocating block 32 does not reciprocate up and down. When the driving member 1 rotates in reverse, the first ratchet wheel 43 and the first one-way ratchet pawl do not cooperate, that is, the rotating shaft 4 does not drive the reciprocating lead screw 41 to rotate, the second ratchet wheel 34 and the second one-way ratchet pawl cooperate, the rotating rod 3 drives the reciprocating rod 31 to rotate, the reciprocating rod 31 drives the reciprocating block 32 to reciprocate up and down. The first ratchet wheel 43 and the first one-way ratchet pawl, and the second ratchet wheel 34 and the second one-way ratchet pawl are prior arts and will not be elaborated in this specification.

[0023] See Figures 1 to 4 In a further embodiment, connecting rods 33 are provided on both sides of the bottom of the reciprocating block 32. The connecting rods 33 are fixedly connected to the top of the sliding plate 71. The connecting rods 33 are used to connect the sliding plate 71 and the reciprocating block 32. When the driving member 1 rotates in the reverse direction, the reciprocating block 32 reciprocates up and down under the action of the reciprocating rod 31. The reciprocating block 32 drives the connecting rods 33 to move, that is, the sliding plate 71 reciprocates up and down. The cutting tool 72 at the bottom of the sliding plate 71 reciprocates up and down. On the one hand, the cutting tool 72 can better crush food. On the other hand, when cleaning the cutting tool 72, the reciprocating up and down of the cutting tool 72 can make the cutting tool 72 cleaner. At the same time, the cutting tool 72 is detachably arranged, so that different cutting tools 72 can be replaced when crushing different foods.

[0024] See Figures 1 to 4 In a further embodiment, one end of the connecting rod 6 is rotatably connected to the threaded block 42, and the other end of the connecting rod 6 is rotatably connected to one side of the baffle 9. The baffle 9 passes through the crushing box 7. The baffle 9 is slidably connected to the scraping plate 91 and cooperates with the connecting rod 6 on the same side respectively. When the driving member 1 rotates forward, the reciprocating lead screw 41 drives the threaded block 42 to descend. An opening is provided at the bottom of the crushing box 7 for discharging food. Baffles 9 are respectively inserted through both sides of the bottom of the crushing box 7. The connecting rod 6 pushes the baffle 9 into the crushing box 7, so that the two baffles 9 cooperate to close the opening at the bottom of the crushing box 7 to prevent food from leaking out during crushing. When the crushing is completed, the driving member 1 continues to rotate forward, and the reciprocating lead screw 41 drives the threaded block 42 to rise. Then the connecting rod 6 separates the two baffles 9. Because the two baffles 9 move away from each other, there is a certain gap between the two baffles 9. Therefore, a certain amount of food can be discharged according to the opening degree of the gap between the two baffles 9.

[0025] See Figures 1 to 4 In a further embodiment, when the baffle 9 is separated, the upper scraping plate is used to scrape off the remaining food on the baffle 9, and the lower scraping plate is used to support the baffle 9 to prevent the baffle 9 from tilting during movement. The metering of food sampling can be controlled by the separation degree of the baffle 9.

[0026] See Figures 1 to 4 In a further embodiment, a feed inlet 5 is provided on one side of the crushing box 7. An opening is provided at the bottom of the base 8. The size of the opening is the same as that of the baffle 9 and is directly opposite to the baffle 9. The opening can facilitate the collection of sampled food.

[0027] See Figures 1 to 4 In a further embodiment, the driving member 1 is a rotary motor.

[0028] In the implementation process of the present utility model: When food needs to be crushed and sampled, the driving member 1 rotates forward, the first ratchet wheel 43 and the first one-way ratchet pawl cooperate, the rotating shaft 4 drives the reciprocating lead screw 41 to rotate, the reciprocating lead screw 41 drives the threaded block 42 to reciprocate, the second ratchet wheel 34 and the second one-way ratchet pawl do not cooperate, that is, the rotating rod 3 does not drive the reciprocating rod 31 to rotate, the reciprocating block 32 does not reciprocate up and down, the reciprocating lead screw 41 drives the threaded block 42 to descend, the connecting rod 6 pushes the baffle 9 into the crushing box 7, so that the baffle 9 is closed to prevent food leakage during crushing. When the driving member 1 rotates reversely, the first ratchet wheel 43 and the first one-way ratchet pawl do not cooperate, that is, the rotating shaft 4 does not drive the reciprocating lead screw 41 to rotate, the second ratchet wheel 34 and the second one-way ratchet pawl cooperate, the rotating rod 3 drives the reciprocating rod 31 to rotate, the reciprocating rod 31 drives the reciprocating block 32 to reciprocate up and down, the reciprocating block 32 drives the connecting rod 33 to move, that is, the sliding plate 71 reciprocates up and down, and the cutter 72 at the bottom of the sliding plate 71 reciprocates up and down to crush the food. After crushing is completed, the driving member 1 continues to rotate forward, the reciprocating lead screw 41 drives the threaded block 42 to rise, and then the connecting rod 6 separates the two baffles 9. Because the two baffles 9 move away from each other, there is a certain gap between the two baffles 9. Therefore, a certain amount of food can be discharged according to the opening degree of the gap between the two baffles 9.
