[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figure 1-2 The embodiments of this utility model include:

[0025] An adjustable vertical mortar mixer has the following structure: a frame body 1, a mixing unit 2, and a hopper unit 3. The mixing unit and the hopper unit are mounted on the frame body and are movably connected to each other.

[0026] Preferably, the bottom of the frame body is provided with rollers 11.

[0027] In a further preferred embodiment, a push-pull armrest 12 is provided on the side of the frame body.

[0028] The stirring unit 2 includes a stirring fixing frame 21, a fixing frame base 22, a locking waist-shaped hole, a locking screw hole, a locking bolt, a locking nut, a stirrer 23, and a stirring driver.

[0029] A stirring bracket and multiple locking screw holes are provided on the bracket base, with the locking screw holes located on the outer periphery of the stirring bracket. The frame body has multiple sets of locking slotted holes. Locking bolts pass through these slotted holes and locking screw holes and connect to locking nuts to secure the bracket base to the frame body. The upper end of the stirrer is rotatably connected to the stirring bracket. The stirring driver is located on top of the stirring bracket and connected to the stirrer to drive its rotation.

[0030] When the position of the agitator needs to be adjusted (especially after changing the hopper), the locking nut and locking bolt can be loosened, and then the position of the fixed frame base can be moved back and forth. When it is adjusted to the appropriate position, the locking nut and bolt can be tightened.

[0031] More preferably, the agitator includes an agitation connecting shaft whose upper end is connected to the agitation fixing frame and whose lower end extends into the hopper, and a plurality of agitation blades disposed on the agitation connecting shaft.

[0032] More preferably, the stirring actuator can adopt a common driving structure such as a motor.

[0033] The hopper unit 3 includes a mixing hopper 31, a base 32, a rotating table 33, a rotating drive unit 39, a contour limiting groove 34, a clamping part 35, and a protective cover 36.

[0034] The base is mounted on the frame body, and the rotary table is movably connected to the base. The output end of the rotary drive unit is connected to the bottom surface of the rotary table to drive the rotary table to rotate on the base. The top surface of the rotary table is provided with a contouring limiting groove, and the lower part of the mixing hopper is movably mounted in the contouring limiting groove.

[0035] More preferably, the rotary drive unit can adopt a common drive structure such as a motor.

[0036] Preferably, the rotary table and the rotary drive unit are detachably connected to facilitate the replacement of different rotary tables. Multiple contouring limiting grooves of different sizes can be arranged concentrically on the rotary table from top to bottom, that is, the diameter of the contouring limiting grooves decreases from top to bottom. This not only allows for the placement of different mixing hoppers, but also eliminates the need to replace the rotary table.

[0037] In a further preferred embodiment, the bottom surface of the rotary table is rotatably connected to the base via bearings to improve the smoothness and stability of the rotary table's rotation.

[0038] The clamping part is movably mounted on the base outside the contour limiting groove to move closer to or further away from the mixing hopper, thereby clamping or releasing the mixing hopper. An elastic buffer pad is provided on the inner wall of the clamping part. Specific Implementation

[0039] The clamping part includes a left clamping part and a right clamping part. The bidirectional lead screw 37 is mounted on the base through a bearing seat. The left clamping part and the right clamping part are respectively connected to two lead screw nuts on the bidirectional lead screw, so that the rotation of the lead screw in the bidirectional lead screw drives the lead screw nuts and the clamping part to move back and forth synchronously, so as to clamp or release the mixing hopper. Specific Implementation

[0040] The base is provided with multiple guide grooves, and each guide groove is movably connected to a clamping part, that is, the bottom of the clamping part is slidably connected to the guide groove.

[0041] The clamping part can move back and forth under the action of a translational actuator such as a cylinder. Alternatively, an adjusting slotted hole can be provided on the guide groove / clamping part, and an adjusting screw hole can be provided on the clamping part / guide groove. Then, the adjusting bolt is passed through the adjusting slotted hole and the adjusting screw hole and connected to the adjusting nut to fix the clamping part.

[0042] In a further preferred embodiment, the inner wall of the clamping part is provided with a contoured pressing surface, which can be set and adjusted according to the shape of the outer wall of the mixing hopper, and can specifically adopt an arc-shaped or planar structure.

[0043] Further preferably, the clamping part can be disassembled for maintenance and replacement.

[0044] The bottom of the protective cover is movably connected to the clamping part, and its upper part extends toward the mixing hopper to form a top cover 38, thereby covering the top opening of the mixing hopper.

[0045] Further preferably, the top cover is provided with clearance grooves. After the clamping part is clamped, multiple clearance grooves can form clearance holes that allow the agitator to pass through and move. An observation port and a feeding port can also be provided to meet different usage needs.

[0046] More preferably, the protective cover can be an inverted L-shaped structure.

[0047] Preferably, the bottom of the protective cover can be connected to the clamping part by means of screw fixing, plugging, or other methods. For example, the upper part of the clamping part is provided with a slot, and the lower part of the protective cover can be plugged into the slot for fixation.

[0048] When it is necessary to replace the mixing hopper, first remove the clamping part outward to keep it away from the outer wall of the mixing hopper. After taking the mixing hopper out of the contour limiting groove, place the new mixing hopper in the corresponding contour limiting groove. Adjust the clamping part so that it is close to and tightly attached to the outer wall of the mixing hopper to fix the mixing hopper. At the same time, the protective cover will gradually move closer under the action of the clamping part to cover the opening of the mixing hopper.

[0049] The beneficial effects of this adjustable vertical mortar mixer are:

[0050] 1. Not only can different mixing bins be replaced according to actual usage needs, but the mixing bins can also be precisely and stably clamped and positioned to prevent displacement and detachment during operation, thereby improving mixing efficiency and quality;

[0051] 2. By setting up a protective cover, it is possible to effectively prevent the splashing and spillage of materials and dust, reduce pollution to the surrounding environment, prevent user misoperation, and improve product safety.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
