DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1, as Figure 1-2 As shown, the present invention provides a technical solution: a pill crushing device, comprising a crushing cylinder 1, a cover plate 4 and a quantitative feeding frame 18, a hinge seat 2 is installed on the side wall of the top of the crushing cylinder 1, and a hinge shaft 3 is arranged between the inner walls of the hinge seat 2, the outer wall of the hinge shaft 3 is hinged with a cover plate 4, and an arc-shaped sealing ring 5 adapted to the inner wall of the crushing cylinder 1 is installed at the bottom end of the cover plate 4, and a rubidium magnetic block 6 is arranged on one side of the crushing cylinder 1 and the cover plate 4, and the rubidium magnetic blocks 6 are fitted with each other, a motor 9 is arranged at the top of the cover plate 4, a crushing shaft 10 is installed at the output end of the motor 9 through a bearing, and a plurality of crushing blades 11 are installed on the outer wall of the crushing shaft 10, a feeding port 12 is opened at the top of the cover plate 4, a feeding frame 7 is arranged at the bottom end of the crushing cylinder 1, and an electromagnetic valve 8 is arranged on the inner wall of the feeding frame 7, and the operator turns the cover plate 4 around the hinge shaft 3, and the two groups of rubidium magnetic blocks 6 are pressed against each other. The magnetic blocks 6 fit tightly together, and the arc-shaped sealing ring 5 fits tightly against the inner wall of the pulverizing cylinder 1, reaching a closed state at the pulverizing cylinder 1. At this time, the motor 9 can be started to drive the pulverizing shaft 10 to rotate, and the pulverizing shaft 10 drives the pulverizing blade 11 to pulverize the pills in the pulverizing cylinder 1. After the pulverizing is completed, the solenoid valve 8 can be opened to discharge the pills from the discharge frame 7. When it is necessary to clean the inside of the pulverizing cylinder 1, the operator pulls the handle at the position of the cover plate 4 to flip it toward the side of the hinge shaft 3, so that the cover plate 4 flips around the hinge shaft 3, thereby driving the pulverizing shaft 10 and the pulverizing blade 11 to flip and separate from the pulverizing cylinder 1. At this time, the operator can clean the pulverizing cylinder 1 and the pulverizing blade 11 separately, which solves the problem that the blade is set on the inner wall of the pulverizing cylinder 1, resulting in four corners at the pulverizing blade 11 and in the pulverizing cylinder 1, and then the cleaning is not thorough.

[0018] Embodiment 2, as Figure 1-4As shown, the present invention provides a technical solution: a pill crushing device, comprising a quantitative feeding frame 18 provided at the top of a feeding port 12, a quantitative slot 19 provided inside the quantitative feeding frame 18, a positioning seat 13 provided inside the quantitative feeding frame 18, and a cylinder 14 provided inside the positioning seat 13, a quantitative mechanism for positioning and feeding provided at the output end of the cylinder 14, the quantitative mechanism comprising a push rod 15 and a limiting ball 16, a push rod 15 installed at the output end of the cylinder 14, and a material blocking mechanism installed at the top of the push rod 15 The limiting ball 16 has an outer wall matched with the inner wall of the quantitative groove 19, and a guide frame 21 for guiding is installed on the outer wall of the push rod 15. By starting the cylinder 14, the limiting ball 16 is driven to move upward, so that the gap below the quantitative groove 19 flows out, and the pills can fall into the feed port 12 and be put into the crushing cylinder 1. Since the limiting ball 16 moves upward to the gap position above the quantitative groove 19, the pills above the quantitative feeding frame 18 are stopped from being fed, so that the pills fall into the crushing cylinder 1 in batches and in a quantitative manner, reducing labor.

[0019] Embodiment 3, as Figure 1-4 As shown, the present invention provides a technical solution: a pill crushing device, including a cover plate 4 having a threaded groove 17 at the top thereof, and a quantitative feeding frame 18 having an empty groove therein, wherein a positioning screw 20 meshing with the inner wall of the threaded groove 17 is arranged inside the empty groove, and the positioning screw 20 can be rotated to separate from the threaded groove 17, so that the position of the quantitative feeding frame 18 can be removed, so as to facilitate the placement of quantitative feeding frames 18 with different feeding diameters.

[0020] Working principle: First, turn on the external power supply. After the operator puts the pills into the quantitative feeding frame 18, they pass through the quantitative slot 19 and stay above the limit ball 16. At this time, the operator can start the cylinder 14 to drive the limit ball 16 to move upward, so that the position below the quantitative slot 19 flows out of the gap, and the pills can fall into the feed port 12 and be put into the crushing cylinder 1. Since the limit ball 16 moves upward to the gap position above the quantitative slot 19, the pills above the quantitative feeding frame 18 are stopped from being fed, so that the pills fall into the crushing cylinder 1 in batches and quantitatively, reducing labor. The motor 9 can be started to drive the crushing shaft 10 to rotate, and the crushing shaft 1 0 drives the crushing blade 11 to crush the pills in the crushing cylinder 1. After the crushing is completed, the solenoid valve 8 can be opened to discharge the pills from the discharge frame 7. When it is necessary to clean the crushing cylinder 1, the operator pulls the handle at the cover plate 4 to flip it toward the side of the hinge shaft 3, so that the cover plate 4 flips around the hinge shaft 3, thereby driving the crushing shaft 10 and the crushing blade 11 to flip and separate from the crushing cylinder 1. At this time, the operator can clean the crushing cylinder 1 and the crushing blade 11 respectively, which solves the problem that the blade is set on the inner wall of the crushing cylinder 1, resulting in four corners at the crushing blade 11 and in the crushing cylinder 1, and then the cleaning is not thorough.

[0021] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
