Description

Technical Field

[0001] This utility model relates to the field of veterinary drug processing technology, and in particular to a square cone mixer for veterinary drug powder. Background Technology

[0002] In veterinary drug processing, a cone mixer is needed to mix various powdered veterinary drug raw materials to obtain veterinary drug powder. The cone mixer achieves the mixing operation through a rotating cone-shaped sealed cylinder. Existing cone mixers have a large cylinder mounting frame that rotates on the frame. The cylinder mounting frame is equipped with a clamping mechanism, which allows the cylinder to be detachably installed on the cylinder mounting frame. This allows the mixed veterinary drug powder to be transported to the next process and installed with another cylinder for mixing another veterinary drug powder. However, the clamping mechanism clamps the four corners of the cylinder. It is necessary to simultaneously clamp or release the four corners of the cylinder to smoothly change the cylinder, which reduces the cylinder changing efficiency and thus reduces the processing efficiency of veterinary drugs.

[0003] Therefore, a cone mixer for veterinary drug powder is needed to solve the above problems. Utility Model Content

[0004] This utility model proposes a cone mixer for veterinary drug powder, in which the rotating shaft of the material cylinder is directly connected to the rotating shaft motor through a gear pair. The locking component facilitates the quick installation and removal of the rotating shaft of the material cylinder from the lifting frame. In conjunction with an independent mobile trolley, it shortens the time for changing the material cylinder and improves the processing efficiency of veterinary drugs.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A veterinary drug powder cone mixer includes a frame and a material cylinder. The material cylinder has a horizontally mounted rotating shaft on each side. A pair of lifting frames are slidably mounted on the frame in a vertical direction. Each rotating shaft is rotatably mounted on a corresponding lifting frame via a locking assembly. One rotating shaft is connected to a shaft drive motor via a gear pair. Each locking assembly includes a bearing seat fixedly mounted on the lifting frame. A locking pin and a closing pressure rod are fixedly mounted on the bearing seat. A bearing cover plate is hinged to the bearing seat, forming an installation cavity between the bearing seat and the bearing cover plate. A tension spring is provided between the bearing cover plate and the corresponding lifting frame. A locking rocker arm is hinged to the bearing cover plate. One end of the locking rocker arm has a locking groove adapted to the locking pin. An unlocking knob is threaded onto the locking rocker arm, abutting against the other end of the locking rocker arm. A compression spring is provided between the locking rocker arm and the bearing cover plate.

[0007] As a preferred technical solution, each of the rotating shafts is equipped with a rotating bearing, and the two rotating bearings are respectively matched with the corresponding mounting cavities.

[0008] As a preferred technical solution, the locking rocker arm is hinged to the corresponding bearing cover plate via a hinge shaft, which is located between the locking groove and the unlocking knob.

[0009] As a preferred technical solution, the compression spring and the unlocking knob are respectively disposed on both sides of the end of the locking rocker arm.

[0010] As a preferred technical solution, each of the mounting cavities is respectively disposed between the corresponding locking rocker arm and the corresponding closing pressure rod.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0012] Since the veterinary drug powder cone mixer includes a material cylinder, a locking assembly, and a lifting frame, the material cylinder containing veterinary drug raw materials is moved so that the rotating shaft is above the corresponding bearing seat. The lifting frame moves upward, and the rotating shaft abuts against and pushes the corresponding closing pressure rod, causing the bearing cover plate to rotate towards the corresponding bearing seat. When the rotating shaft is in the installation cavity, under the action of the compression spring, the locking rocker arm engages with the corresponding locking pin, and the bearing cover locks with the corresponding bearing seat. That is, the locking assembly locks the material cylinder.

[0013] This invention connects the rotating shaft of the feed cylinder directly to the rotating shaft motor via a gear pair. The locking component facilitates quick installation and removal of the rotating shaft of the feed cylinder from the lifting frame. Combined with an independent mobile trolley, it shortens the time for changing the feed cylinder and improves the processing efficiency of veterinary drugs.

[0014] Because the veterinary drug powder cone mixer includes a locking assembly, which consists of a bearing seat and a bearing cover plate hinged together, the locking groove and the locking pin are engaged and disengaged by locking the rocker arm, compressing the spring and unlocking the knob, thereby locking and disengaging the bearing seat and the bearing cover plate, and thus locking and unlocking the rotating shaft by the locking assembly.

[0015] By fixing a closing pressure rod to the bearing cover plate, the rotating shaft during the descent process abuts against and pushes the closing pressure rod, thereby driving the bearing cover plate to rotate, thus realizing the automatic closing of the bearing cover plate. Then, by locking the rocker arm, locking the locking pin and compressing the spring, the rotating shaft is locked.

[0016] This invention mounts the rotating shaft onto the lifting frame via a locking assembly, eliminating the need for a large material cylinder mounting frame. This significantly reduces the overall weight and size of the equipment. The rotating shaft drive motor only drives the material cylinder to rotate, eliminating the need to move the bulky frame and reducing the equipment's energy consumption. Attached Figure Description

A tension spring 11 is provided between the bearing cover plate 9 and the corresponding lifting frame 4. A locking rocker arm 12 is hinged to the bearing cover plate 9. One end of the locking rocker arm 12 is provided with a locking groove 13 that matches the locking pin 7. An unlocking knob 14 is threaded onto the locking rocker arm 12. The unlocking knob 14 abuts against the other end of the locking rocker arm 12. A compression spring 15 is provided between the locking rocker arm 12 and the bearing cover plate 9.

[0032] Each rotating shaft 3 is equipped with a rotating bearing 16, and the two rotating bearings 16 are respectively matched with the corresponding mounting cavity 10.

[0033] Additionally, the locking rocker arm 12 is hinged to the corresponding bearing cover plate 9 via a hinge shaft 17, which is located between the locking groove 13 and the unlocking knob 14.

[0034] like Figure 7 As shown, the compression spring 15 and the unlocking knob 14 are respectively located on both sides of the end of the corresponding locking rocker arm 12.

[0035] Each mounting cavity 10 is respectively located between the corresponding locking rocker arm 12 and the corresponding closing pressure rod 8.

[0036] like Figure 1 , Figure 2 and Figure 8 As shown, each lifting frame 4 is fixedly equipped with a pair of sliders 18, and the frame 1 is fixedly equipped with two pairs of vertically arranged slide rails 19.
