Utility Model Content

[0005] The purpose of the utility model is to provide a grain grinder that is easy to maintain, which solves the problem that the grinder in the above-mentioned technology cannot sieve the grain when in use, resulting in the processed grain containing some residues after the grinding, and its internal parts age after long-term use and the grinder cannot be quickly opened for replacement.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grain grinder that is easy to maintain, comprising a machine body and a lifting mechanism arranged outside the machine body, wherein the lifting mechanism comprises a working component and a rotating component;

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The feed pipe and the reflux pump are connected to the machine body and the outer shell. When the grain is crushed, the reflux pump transports the crushed grain from the feed pipe to the outer shell. Then the motor drives the turntable to rotate, and the belt and the hopper rotate synchronously to lift the grain powder and transport it to the discharge pipe and the discharge box. The uncrushed fragments cannot fall into the discharge pipe due to their own weight. The fragments will flow back from the feed pipe to the machine body and be crushed again, avoiding the problem of too much backlog of feed being unable to feed and causing the feed pipe to be blocked and unable to discharge, and the problem of too slow discharge speed and low efficiency.

[0017] 2. The connecting piece and the buckle block are installed on the outer wall of the machine body by setting. When it is necessary to replace parts or feed materials inside the machine body, the card block is pushed to open the cover from behind the connecting piece, and the first rocker slides into the second rocker through the sliding shaft and aligns with it. Conversely, when it needs to be closed, the cover is buckled down to allow the buckle block to enter from the connecting piece. At this time, when the buckle block hits the card block, it will rotate outward to allow the buckle block to be stuck in the connecting piece, and then the card block automatically rotates back to clamp the buckle block. The baffle will prevent the card block from sliding too far, thereby avoiding the situation where the machine body cannot be opened quickly due to the need for disassembly and replacement, resulting in a waste of time and low efficiency.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-2 As shown, a grain grinder that is easy to maintain in the figure includes a machine body 1 and a lifting mechanism arranged outside the machine body 1, and the lifting mechanism includes a working component and a rotating component;

[0026] The working assembly includes a shell 2, the outer wall of the body 1 is fixedly connected to the shell 2, the outer wall of the shell 2 is fixedly connected to a feed pipe 3, the outer wall of the feed pipe 3 is fixedly connected to a reflux pump 4, the outer wall of the shell 2 is fixedly connected to a discharge pipe 5, and one end of the discharge pipe 5 is fixedly connected to a discharge box 6;

[0027] In this embodiment, the rotating assembly includes a first motor 7, the outer wall of the housing 2 is fixedly connected to the motor 7, one end of the motor 7 is rotatably connected to a turntable 8, the outer wall of the turntable 8 is rotatably connected to a belt 9, and the outer wall of the belt 9 is fixedly connected to a hopper 10.

[0028] Among them, Figure 2 As shown, the body 1 fits tightly with the surface of the reflux pump 4, and the appearance of the discharge box 6 is conical, which is conducive to the grain to directly enter the outer shell 2 for screening and discharging after being crushed, and to speed up the efficiency, avoid the problem of excessive backlog of materials that causes the feed pipe 3 to be blocked and unable to discharge materials, and the problem of low efficiency due to too slow discharging speed, thereby realizing the fixed control operation of the feed pipe 3 and the discharge pipe 5.

[0029] Example 2

[0030] See also Figure 2 As shown, the present embodiment provides a grain grinder that is easy to maintain. In addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features: two groups of turntables 8 are arranged, and the position relationship of the two groups is symmetrical about the midpoint of the outer shell 2, which is conducive to the two groups of turntables 8 rotating at a faster speed and higher efficiency, avoiding the problem of too slow conveying speed or failure to convey, and realizing the control operation of the rotation of the turntable 8.

[0031] In this embodiment, the hopper 10 forms a rotating structure with the motor 7 through the belt 9 and the turntable 8, which is beneficial for the grain to be transported and screened through multiple groups of hoppers 10 after being crushed, avoiding the situation where some of the crushed grain remains uncrushed and causes the problem of low quality, thereby realizing the control operation of the rotation of the hopper 10.

[0032] Example 3

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the present embodiment provides a grain grinder which is easy to maintain. In addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features: the outer wall of the body 1 is fixedly connected with a connecting piece 11, the outer wall of the connecting piece 11 is rotatably connected with a clamping block 12, the outer wall of the clamping block 12 is fixedly connected with a baffle 13, the outer wall of the body 1 is fixedly connected with a buckle block 14, the outer wall of the body 1 is fixedly connected with a first rocker arm 15, the outer wall of the first rocker arm 15 is fixedly connected with a sliding shaft 16, and the outer wall of the sliding shaft 16 is slidably connected with a second rocker arm 17.

[0034] Among them, the buckle block 14 forms a buckle structure with the connecting piece 11 through the clamping block 12 and the baffle 13, which is beneficial for only moving the clamping block 12 when it is necessary to disassemble and replace the parts inside the body 1, avoiding the situation where the body 1 cannot be opened quickly due to the need for disassembly and replacement, resulting in time waste and low efficiency, and realizing the control operation of the opening and closing of the body 1.

[0035] In this embodiment, the outer wall of the second rocker 17 is provided with a sliding groove that matches the sliding shaft 16. The body 1 forms a sliding structure with the second rocker 17 through the first rocker 15 and the sliding shaft 16, which is conducive to the lid being directly hung on the side of the body 1 when opening the body 1, and is also more convenient when closing, avoiding damage during the opening or closing process, and realizing fixed control operation of the body 1.

[0036] During use: first, the feed pipe 3 and the reflux pump 4 are connected to the machine body 1 and the outer shell 2. When the grain is crushed, the crushed grain is transported from the feed pipe 3 to the outer shell 2 through the reflux pump 4, and then the motor 7 drives the turntable 8 to rotate, and the belt 9 and the hopper 10 rotate synchronously to lift the grain powder and transport it to the discharge pipe 5 and the discharge box 6. The uncrushed fragments will not be able to fall into the discharge pipe 5 due to their own weight. The fragments will flow back from the feed pipe 3 to the machine body 1 and be crushed again, avoiding the problem of too much backlog of material that cannot be fed, resulting in the feed pipe 3 being blocked and unable to discharge material, and the problem of too slow discharge speed and low efficiency.

[0037] Finally, by setting the connecting piece 11 and the buckle block 14 to be installed on the outer wall of the body 1, when it is necessary to replace parts or feed materials inside the body 1, the block 12 is pushed to open the lid from behind the connecting piece 11, and the first rocker 15 slides from the second rocker 17 through the sliding shaft 16 to align with it. Conversely, when it needs to be closed, the lid is buckled down to allow the buckle block 14 to enter from the connecting piece 11. At this time, when the buckle block 14 hits the block 12, it will rotate outward to allow the block 14 to be stuck in the connecting piece 11, and then the block 12 will automatically rotate back to clamp the block 14. The baffle 13 will prevent the block 12 from sliding too far, thereby avoiding the situation where the body 1 cannot be opened quickly due to the need for disassembly and replacement, resulting in a waste of time and low efficiency.
