[0015] Figure 2 for Figure 1 Cross-sectional view of the mixing cylinder.

[0016] The figure marks in the drawings of the specification include: support frame 1, mixing barrel 2, driver 3, hopper 4, material disturbance frame 5, discharge chute 6, base 7, telescope 8, material shaking column 9, elastic buffer block 10, adjustable limiting assembly 11, spline block 111, regulator 112. DETAILED DESCRIPTION

[0017] The utility model is further described in detail below through specific implementation methods:

[0018] like Figure 1As shown, an embodiment of the utility model proposes a medicinal raw material mixing device, comprising a support frame 1, a mixing drum 2 and a driver 3; wherein the mixing drum 2 is octahedral and is rotatably connected to the support frame 1, the rotation center line of the mixing drum 2 is colinear with the connecting line of its two oppositely arranged vertices, and a hopper 4 with an adjustable sealing state is arranged at a different vertex on the mixing drum 2, and the central axis of the hopper 4 is arranged perpendicular to the rotation center line of the mixing drum 2; the driver 3 is arranged on the support frame 1 and is connected to the mixing drum 2 to drive the mixing drum 2 to rotate.

[0019] When feeding, start the driver 3 to drive the mixing drum 2 to rotate until the hopper 4 is rotated to the top of the mixing drum 2, the driver 3 stops running, and then the hopper 4 is opened to add the raw materials from the hopper 4 into the mixing drum 2. After the feeding is completed, the hopper 4 is sealed; then the driver 3 is started again to drive the mixing drum 2 to rotate, and the raw materials continue to roll in the mixing drum 2. After the raw materials are mixed in the mixing drum 2 for a certain period of time, the raw materials are mixed evenly in the mixing drum 2; then when the mixing drum 2 rotates to make the hopper 4 rotate to the bottom of the mixing drum 2, the driver 3 stops running. At this time, the hopper 4 is opened to discharge the evenly mixed raw materials from the mixing drum 2.

[0020] The medicinal raw material mixing device uses the shape design of the mixing drum 2 and the arrangement of the mixing drum 2 on the support frame 1 to enable the driver 3 to drive the mixing drum 2 to rotate, so that the block or rod-shaped Chinese medicinal raw materials can continuously roll in the mixing drum 2, and have a better mixing effect; at the same time, the shape design of the mixing drum 2 also makes it convenient for the evenly mixed raw materials to be quickly discharged from the hopper 4 in the mixing drum 2 during discharge, without any dead corners.

[0021] In this embodiment:

[0022] The mixing drum 2 is in the shape of a regular octahedron, and the left and right vertices of the mixing drum 2 are planarized so that the left and right vertices of the mixing drum 2 are fixedly connected with rotating shafts, and the two rotating shafts are rotatably connected to the support frame 1, one of the rotating shafts is connected to the driver 3, and the driver 3 can be a motor. A hopper 4 is set at a vertex on the top of the mixing drum 2, and the mixing drum 2 can be rotated to place the hopper 4 above the mixing drum 2 for feeding or to place the hopper 4 below the mixing drum 2 for discharging.

[0023] The hopper 4 is provided with a retaining baffle, which can be slid out of the hopper 4 to open the hopper 4 for feeding or discharging; the retaining baffle can be slid into the hopper 4 to seal the mixing barrel 2, so that the raw materials can be stably tumbled and mixed in the mixing barrel 2. The cooperation between the retaining baffle and the hopper 4 is a prior art.

[0024] It is worth noting that by starting and stopping the driver 3, it is not possible to accurately control whether the hopper 4 is above or below the mixing drum 2. The driver 3 can be stopped first, and when the mixing drum 2 stops rotating, the mixing drum 2 can be manually rotated to make the hopper 4 above or below the mixing drum 2 for feeding or discharging.

[0025] In order to better understand this solution, the structure will be further optimized below.

[0026] In order to further improve the stirring effect of the raw materials in the mixing barrel 2, as Figure 2 As shown, according to another embodiment of the utility model, in the medicinal raw material mixing device, a material disturbing frame 5 is fixedly arranged in the mixing barrel 2. During the rotation of the mixing barrel 2, the raw materials are continuously tumbled in the mixing barrel 2, and the raw materials hit the material disturbing frame 5 during the tumbling process, so as to increase the tumbling degree of the raw materials, thereby improving the mixing effect of the raw materials.

[0027] Based on the above scheme:

[0028] The material disturbing frame 5 comprises a cross fixed in the mixing drum 2, the cross is coplanar with the rotation center line of the mixing drum 2, and the central axis of the hopper 4 intersects with the cross at the intersection of the cross.

[0029] The material disturbing frame 5 is designed as a cross, which has a simple structure and can meet the requirements for raw material mixing, while also enhancing the structural strength of the mixing barrel 2. The arrangement of the cross in the mixing barrel 2 prevents the cross from hindering the feeding or discharging of the hopper 4.

[0030] like Figure 1 As shown, according to another embodiment of the utility model, a medicinal raw material mixing device is provided, wherein a discharge chute 6 is obliquely arranged on the support frame 1 , and a high end of the discharge chute 6 is located below the mixing barrel 2 and on the central axis of the hopper 4 .

[0031] Here:

[0032] After the raw materials are evenly mixed in the mixing drum 2, the mixing drum 2 is rotated to rotate the hopper 4 below it. At this time, the high end of the discharge chute 6 is located below the opening of the hopper 4, and the raw materials discharged from the opening of the hopper 4 fall into the discharge chute 6 and are discharged.

[0033] like Figure 1 As shown, according to another embodiment of the utility model, the medicinal raw material mixing device further includes a base 7, the support frame 1 is slidably arranged on the top of the base 7 along the horizontal direction, and a telescopic device 8 for driving the support frame 1 to slide is fixedly arranged on the base 7.

[0034] The telescopic device 8 may be a cylinder, and the telescopic adjustment of the cylinder enables the support frame 1 to slide back and forth horizontally on the base 7, which is beneficial to the discharge of the mixing barrel 2 and the discharge trough 6 and avoids the raw materials from being stuck on the cross.

[0035] Based on the above scheme:

[0036] The base 7 is fixedly connected with a material shaking column 9 for cooperating with the material discharging chute 6 . The material discharging chute 6 collides with the material shaking column 9 once per cycle as the supporting frame 1 moves.

[0037] During discharging, the cylinder is telescopically adjusted to make the support frame 1 slide back and forth horizontally on the base 7. Each time the support frame 1 slides back and forth on the base 7, the bottom of the discharge trough 6 collides with the shaking column 9, which is beneficial to speed up the flow of raw materials in the discharge trough 6 and avoid blockage.

[0038] In order to improve safety, an elastic buffer block 10 is provided at the point where the bottom of the discharge trough 6 collides with the material shaking column 9; when the material shaking column 9 collides with the discharge trough 6, it contacts the elastic buffer block 10, thereby reducing the impact force when the bottom of the discharge trough 6 collides with the material shaking column 9 and improving safety in use; the elastic buffer block 10 can be made of materials such as rubber.

[0039] In order to ensure that the feeding and discharging process of the mixing drum 2 is carried out stably, Figure 1 As shown, according to another embodiment of the utility model, in the medicinal raw material mixing device, an adjustable limiting component 11 cooperating with the mixing barrel 2 is arranged between the support frame 1 and the mixing barrel 2, and the adjustable limiting component 11 is used to lock or unlock the mixing barrel 2.

[0040] When the mixing drum 2 is in the process of feeding or discharging materials, the adjustable limiting component 11 locks the mixing drum 2, and the mixing drum 2 works stably at this time; when the mixing drum 2 needs to be rotated to mix the raw materials, the adjustable limiting component 11 first unlocks the mixing drum 2.

[0041] Based on the above scheme:

[0042] The adjustable limiting assembly 11 includes a spline groove and a spline block 111. The spline groove is provided on a rotating shaft fixedly connected to the mixing barrel 2 and rotatably connected to the support frame 1. The spline block 111 is connected to an adjuster 112 fixedly arranged on the support frame 1. The adjuster 112 is used to drive the spline block 111 to move to connect or disconnect with the spline of the spline groove.

[0043] The regulator 112 may be a cylinder, which extends to allow the spline block 111 to be inserted into the spline groove for spline connection, thereby locking the mixing barrel 2; the cylinder contracts to allow the spline block 111 to be withdrawn from the spline groove for disengagement from the spline connection, thereby unlocking the mixing barrel 2. The spline block 111 is specifically a square block, and the spline groove is a square groove. When the mixing barrel 2 is rotated to allow the hopper 4 to be located above or below the mixing barrel 2, the spline block 111 can be smoothly inserted into the spline groove for spline connection, or withdrawn from the spline groove for disengagement from the spline connection.

[0044] When using this solution:

[0045] The adjuster 112 operates to make the spline block 111 withdraw from the spline groove and disengage the spline connection;

[0046] The driver 3 is started to drive the mixing drum 2 to rotate until the hopper 4 is located above the mixing drum 2. The driver 3 stops running and the regulator 112 operates to make the spline block 111 fit into the spline groove for spline connection. At this time, the hopper 4 is opened, and various raw materials are added from the hopper 4 to the mixing drum 2. After the addition is completed, the hopper 4 is closed and the regulator 112 operates to make the spline block 111 withdraw from the spline groove to disengage the spline connection.

[0047] The driver 3 is started to drive the mixing drum 2 to rotate, and various raw materials are continuously rolled and mixed in the mixing drum 2. After mixing for a period of time, the various raw materials are evenly mixed until the hopper 4 is located below the mixing drum 2. The driver 3 stops running and the regulator 112 runs to make the spline block 111 embed into the spline groove for spline connection. At this time, the hopper 4 is opened; at the same time, the telescopic device 8 runs, the support frame 1 slides back and forth, and the raw materials discharged from the hopper 4 fall on the discharge chute 6 and slide away.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
