[0046] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0047] This utility model embodiment provides a uniform feeding structure for a crusher. Please refer to [reference needed]. Figures 1-6 The uniform feeding structure of the crusher is installed on the top of the crusher and includes a material receiving unit, a screw conveyor cylinder 3 and a lifting gate assembly 4.

[0048] Specifically,

[0049] The support unit, located at the top of the crusher 5, includes a mounting base 10 and a support plate 11, with the support plate 11 located on both sides of the crusher 5.

[0050] The material receiving unit includes a pouring box 22 and a material receiving frame 21. Material is poured from the pouring box 22 into the material receiving frame 21.

[0051] The material feeding box 22 has a discharge port 220. A rotating column 221 is installed through the bottom side wall of the material feeding box 22 near its discharge port 220. The rotating column 221 is rotatably connected between two support plates 11, allowing the material feeding box 22 to be tilted. A movable plate 222 is fixed to one end of the outer wall of the material feeding box 22 facing away from the discharge port 220. The other end of the movable plate has a triangular prism-structured insertion part 2220. The edge of the top of the crusher 5 has an insertion groove that matches the insertion part; that is, when the center of gravity of the material feeding box 22 is vertically downward, the insertion part 2220 fits into the insertion groove. A weighing sensor 23 is installed at the bottom of the material feeding box 22 to sense the weight of the Chinese herbal medicine pile inside. The Chinese herbal medicine pile can be added by means of a conveyor or manually.

[0052] The material container 21 is used to hold the pile of traditional Chinese medicine. A discharge port 220 is located below the pouring box 22, meaning that by tilting the pouring box 22, the pile of traditional Chinese medicine inside can be poured into the material container 21 through the discharge port 220. An object detection sensor is installed inside the material container 21 via a mounting box 24 to detect whether there is any pile of traditional Chinese medicine inside the container 21. This object detection sensor can be a photoelectric sensor, an infrared sensor, etc.

[0053] The screw conveyor cylinder 3 is used for conveying the Chinese herbal medicine stockpile to the pulverizer 5. The Chinese herbal medicine stockpile falls into the screw conveyor cylinder 3 through the material container 21 and is then conveyed to the pulverizer 5 by the screw conveyor cylinder 3. The screw conveyor cylinder 3 includes a cylinder body 30 and a screw rod 31.

[0054] The cylinder 30 has a feed hole on one side wall. A material holding frame 21 is inserted and fixed into the feed hole on the side away from the discharge box 22, with the side of the material holding frame 21 near the feed hole open, allowing communication between the material holding frame 21 and the cylinder 30. The material holding frame 21 is angled relative to the cylinder 30, with its feed end higher than its discharge end. The herbal medicine stockpile is transported into the cylinder 30 through the feed hole via the angled material holding frame 21. A discharge pipe 300, matching the pulverizer 5, is located at the bottom of the circumferential wall of the cylinder 30, near the other side of the cylinder 30, for discharging material from the cylinder 30 to the pulverizer 5. The cylinder 30 is connected to the pulverizer 5 via a mounting base 10.

[0055] A screw rod 31 is located inside the cylinder 30, with one end near the feed hole and the other end protruding outside the cylinder and fitted with a motor 32. The motor 32 drives the screw rod 31 to rotate. When the Chinese herbal medicine pile in the container frame 21 falls into the cylinder 30 through the feed hole, the motor 32 drives the screw rod 31 to rotate, pushing the Chinese herbal medicine pile towards the discharge pipe 300, so that the Chinese herbal medicine pile in the cylinder 30 falls into the pulverizer 5 through the discharge pipe 300.

[0056] The lifting gate assembly 4 is installed on the cylinder 30 to match the feed through hole, and is used to block or open the feed through hole. The lifting gate assembly includes a fixed plate 41, a gate body 42, a lifting plate 43, and a control processor 44.

[0057] The fixing plate 41 is symmetrical about the axis of the cylinder 30 and is located on the inner wall area of ​​the cylinder opposite to the receiving frame 21, which is located outside the feed through hole; the two fixing plates 41 are respectively provided with sliding grooves on their opposite surfaces.

[0058] The gate body 42 is slidably connected to the slide groove to match the feed through hole, and is used to block or open the feed through hole. When the gate body 42 rises along the extension direction of the slide groove, the feed through hole can be opened; when the gate body 42 falls along the extension direction of the slide groove, the feed through hole can be blocked. The top end of the gate body 42 protrudes through the cylinder 30.

[0059] The lifting plate 43 has one end connected to the top of the door body, and the other end is provided with a downward-extending mounting column 430. The mounting column 430 is connected to a cylinder 40. The cylinder 40 drives the mounting column 430 to rise and fall along the extension direction of the slide groove, which can drive the door body 42 to rise and fall in the same direction. When the cylinder 40 drives the door body 42 to rise, the feed hole is open, and at this time, the Chinese medicine pile in the receiving frame 21 can fall into the screw conveyor cylinder 3; conversely, when the feed hole is blocked by the door body 42, the Chinese medicine pile in the receiving frame 21 cannot be transferred to the screw conveyor cylinder 3.

[0060] The control processor 44 is electrically connected to the cylinder 40, the weighing sensor 23, and the object detection sensor. Specifically, the input terminals of the control processor 44 are connected to the weighing sensor 23 and the object detection sensor, respectively, and the output terminal of the control processor 44 is connected to the cylinder 40. The control processor 44 can be a PLC (Programmable Logic Controller).

[0061] The weighing sensor 23 senses the added weight in the feeding bin 22 and transmits this weight signal to the control processor 44. The control processor 44 processes the signal into a weight value and compares it with a preset weight range that has an upper and lower weight limit. When the measured weight does not exceed the weight range, the control processor 44 controls the gate 42 to rise. In other words, the cylinder 40 will only drive the gate 42 to rise when the amount of Chinese medicine in the feeding bin 22 reaches a certain level, so that the amount of Chinese medicine entering the pulverizer 5 is stably maintained within a certain range. This helps to ensure intermittent and uniform feeding to the pulverizer 5 without affecting the pulverizing effect. When the object detection sensor detects that there is no Chinese medicine in the material container 21, it transmits a signal to the control processor 44 to control the cylinder 40 to drive the gate 42 to descend and block the feed opening.

[0062] Based on the above embodiments, the working principle of this application is as follows:

[0063] Weighing sensor 23 senses the weight of the Chinese herbal medicine pile in the feeding bin 22. When the measured weight is within the weight range set by the control processor 44, the control processor 44 controls the cylinder 40 to drive the door 42 to rise, tilting the feeding bin 22. The Chinese herbal medicine pile falls into the receiving frame 21 and is then transported through the feed hole to the screw conveyor cylinder 3, which then transports it to the pulverizer 5. At this time, when the object detection sensor detects that there is no Chinese herbal medicine pile in the receiving frame 21, the control processor 44 controls the cylinder 40 to drive the door 42 to descend, sealing the cylinder 30. The above is one feeding process, and the above process is repeated for each subsequent feeding.

[0064] Based on the above embodiments, the advantages of this application are:

[0065] By setting the receiving frame 21 at an angle relative to the screw conveyor cylinder 3, it is beneficial for the Chinese medicine stockpile to fall quickly to the feed through hole by its own gravity. Furthermore, by adding a weighing sensor 23, an object detection sensor, and a control processor 44 to the feeding structure, and having them work together to control the amount of Chinese medicine stockpile entering the pulverizer 5, it is possible to ensure intermittent and uniform feeding to the pulverizer 5. This avoids the phenomenon that the pulverizer will have poor pulverization effect if too much material is manually added to the feeding mechanism in the traditional pulverizer, thus reducing the dependence on manual labor.
