[0002] A chopper is a common kitchen appliance, also called a food processor or blender. Its main function is to chop ingredients such as meat, vegetables, fruits, etc. into minced or pureed substances.

[0003] Existing shredders, such as a grinding device with automatic collection function disclosed in the China Patent Library (application number: 202223004965.7), include a base, a No. 1 motor is fixedly installed on one side of the base, and a driving gear is fixedly connected to the output end of the No. 1 motor. A rotating rod is rotatably connected between the bases, and a driven gear is fixedly installed on one end of the rotating rod. A grinding barrel is fixedly connected between the rotating rods, and a barrel cover is provided above the grinding barrel. A discharge pipe is fixedly installed on one side of the grinding barrel near the top surface, and a threaded pipe cover is provided at one end of the discharge pipe. A No. 2 motor is installed inside the grinding barrel, and a blade is fixedly installed on the output end of the No. 2 motor.

[0004] In the above-mentioned grinding device, motor No. 1 drives the grinding barrel to swing through gear transmission, which makes it convenient to pour out the powder in the grinding barrel and facilitates use. However, when the grinding barrel swings, its weight is completely borne by motor No. 1, which accelerates the wear of motor No. 1 and affects its life. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes a shredder to solve the technical problem of how to increase the service life.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a shredder, comprising a frame, a barrel and a motor fixed at the bottom of the barrel, a blade is arranged in the barrel, a main shaft of the motor extends into the barrel and is connected to the blade, a left rotating shaft and a right rotating shaft are respectively arranged horizontally on both sides of the barrel, and the left rotating shaft and the right rotating shaft are coaxially arranged, the adjacent ends of the left rotating shaft and the right rotating shaft are fixed on the barrel, and the ends of the left rotating shaft and the right rotating shaft that are far away are rotatably arranged on the frame, characterized in that a rod-shaped limiting member 1 is vertically fixed on the outer side wall of the left rotating shaft, and the axes of the limiting member 1 and the barrel are arranged parallel; a rod-shaped limiting member 2 is horizontally fixed on the frame at the rear side of the left rotating shaft, and the limiting member 1 abuts against the limiting member 2 when the barrel swings to a vertical position; a limiting groove is arranged on the outer side wall of the right rotating shaft, and a limiting rod matching the limiting groove is also arranged on the frame, and one end of the limiting rod can be inserted into the limiting groove or extended out of the limiting groove when the barrel swings to a vertical position under the action of external force.

[0007] When in use, limit piece 1 and limit piece 2 cooperate to make the barrel body swing to a vertical position, align the limit rod with the limit slot, and insert one end of the limit rod into the limit slot to completely lock the left and right rotating shafts, so as to lock the barrel body in a vertical state and perform the shredding operation stably.

[0008] Under the action of the limiting structure composed of the limiting rod and the limiting member 1 and the limiting member 2, the barrel body is stably kept in a vertical state, and the limiting structure is not subjected to force when the barrel body swings, which can effectively reduce the load of the limiting structure when in use, thereby extending the life of the shredder.

[0009] In the above-mentioned shredder, the above-mentioned limit rod is horizontally arranged and located in front of the right rotating shaft, and the axes of the limit rod and the right rotating shaft are vertically arranged, so that the layout of the limit rod and the limit groove is more reasonable, which is conducive to design and assembly.

[0010] In the above-mentioned shredder, the limit rod is slidably connected to the frame so that the limit rod can slide back and forth along its own axis, thereby improving the movement accuracy of the limit rod, making the barrel state switching smoother and more convenient to use.

[0011] In the above-mentioned shredder, a spring is also provided on the frame to make the limit rod have a tendency to move backward, so that when the barrel body is in a vertical state, the limit rod automatically extends into the limit groove under the action of the spring to lock the barrel body, so that the limit rod operation can be performed completely manually, which not only simplifies the structure but also facilitates operation.

[0012] In the above-mentioned shredder, there are two limit grooves distributed along the circumference of the right rotating shaft, and the ends of the limit rod can be respectively inserted into the two limit grooves. When in use, when the end of the limit rod is inserted into one of the limit grooves, the barrel body is locked in a vertical state; when the end of the limit rod is inserted into the other limit groove, the barrel body is locked in a tilted state, which is convenient for taking out the shredded objects in the barrel body.

[0013] In the above-mentioned shredder, the limit groove is strip-shaped and its length extends along the axial direction of the right rotating shaft. The width of the limit groove is open on one side. The ends of the limit rod can be pressed on the other side of the width of the limit groove to limit the clockwise or counterclockwise rotation of the right rotating shaft respectively, so as to reduce the matching accuracy requirements of the limit groove and the limit rod and facilitate processing.

[0014] In the above-mentioned shredder, the spring is sleeved on the limit rod, and a ring-shaped limit seat is provided on the rear end side wall of the limit rod, and the two ends of the spring act on the frame and the limit seat respectively. The above-mentioned design can ensure the stable operation of the spring.

[0015] In the above-mentioned shredder, a long rod is fixed to the right end side wall of the right shaft, and the angle between the axes of the long rod and the right shaft is an acute angle, so as to provide a more relaxed gripping point for the user to swing the barrel for easy use.

[0016] As another solution, in the above-mentioned shredder, a driving member for automatically driving the limit rod to slide is fixedly provided on the frame.

[0017] In the above-mentioned shredder, the types of the first limiting member and the second limiting member are both bolts, which is convenient for installation.

[0018] Compared with the prior art, this shredder has the following advantages:

[0019] 1. The cooperation between the first and second limit members not only makes the barrel body swing to a vertical position, but also makes the limit rod align with the limit groove. That is, in the present application, the cooperation between the first and second limit members has a dual-purpose effect, which simplifies the structure and facilitates assembly.

[0020] 2. Under the action of the limiting structure composed of the limiting rod and the limiting member 1 and the limiting member 2, the barrel body is kept in a stable vertical state, and the limiting structure is not subjected to force when the barrel body swings, which can effectively reduce the load of the limiting structure when in use, thereby extending the life of the shredder.

[0028] Specifically,

[0029] like Figure 2 and Figure 4 As shown, a left rotating shaft 6 and a right rotating shaft 7 are respectively arranged horizontally on both sides of the barrel body 2, and the left rotating shaft 6 and the right rotating shaft 7 are arranged coaxially. The adjacent ends of the left rotating shaft 6 and the right rotating shaft 7 are fixed on the barrel body 2, and the ends of the left rotating shaft 6 and the right rotating shaft 7 that are far away are rotatably arranged on the frame 1. Among them, a rod-shaped limiting member 8 is vertically fixed on the outer wall of the left rotating shaft 6, and the axes of the limiting member 8 and the barrel body 2 are arranged parallel, and the frame 1 is horizontally fixed with a rod-shaped limiting member 2 9 on the rear side of the left rotating shaft 6, and the limiting member 1 8 abuts against the limiting member 2 9 when the barrel body 2 swings to a vertical position to limit the counterclockwise rotation of the left rotating shaft 6; a limiting groove 7a is arranged on the outer wall of the right rotating shaft 7, and a limiting rod 10 matching the limiting groove 7a is also arranged on the frame 1, and one end of the limiting rod 10 can be inserted into the limiting groove 7a or extended out of the limiting groove 7a when the barrel body 2 swings to a vertical position under the action of external force.

[0030] When in use, the limit member 1 8 and the limit member 2 9 cooperate to make the barrel body 2 swing to a vertical position, and align the limit rod 10 with the limit groove 7a, and insert one end of the limit rod 10 into the limit groove 7a to completely lock the left rotating shaft 6 and the right rotating shaft 7, so as to lock the barrel body 2 in a vertical state and perform the shredding operation stably.
