Description

Technical Field

[0001] This utility model relates to the field of concrete mixer technology, and in particular to an adjustable concrete mixer. Background Technology

[0002] A mixer consists of a base, mixing tank, drive wheel, servo motor, transmission device, and support frame. It is a common piece of equipment used to mix concrete.

[0003] Existing technologies, such as the invention with publication number CN109203242A, disclose a portable concrete mixing tank. This patent uses a tank body and a support frame to support the tank body. Multiple transmission gear rings are distributed around the circumference of the tank body. The transmission gear rings mesh with transmission gears on the support frame. The transmission gears are located on both sides of the tank body. One side of the transmission gear is driven by a drive device on the support frame. The support frame is a split structure, with the split parts located on both sides of the tank. The split parts are two parts and are fixed together by a connector. This type of portable concrete mixing tank has the advantages of convenient installation and disassembly, small volume during transportation, and suitability for outdoor operations.

[0004] The inventors discovered in daily use that in existing technologies, belts that are too loose or too tight will reduce transmission efficiency. If the belt is too loose, it may cause slippage, while if it is too tight, it may increase friction, affecting the operating efficiency of the motor and transmission disc. Inappropriate belt tension will cause excessive wear on equipment components such as motors, transmission discs, and pulleys, reducing their service life and increasing maintenance costs.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable concrete mixer.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable concrete mixer, comprising a base and an adjustment structure. A mixing tank is mounted on the upper surface of the base, and a transmission device is mounted on the upper surface of the base. A transmission wheel is mounted at one end of the transmission device and is connected to the mixing tank. Four supports are fixedly connected to the lower surface of the base. A servo motor is mounted on one side of one of the supports. The servo motor is connected to one of the supports via the adjustment structure. An adjustment structure is provided on the inner wall of one of the supports. The adjustment structure includes a sliding groove, which is formed on the support. A slider is slidably connected to the wall, and the servo motor is mounted on the slider. A connecting plate is fixedly connected to one side of the servo motor. A plug rod is slidably connected to the inner wall of the connecting plate. Several insertion holes are opened between the connecting plates near the plug rod. The insertion holes are slidably connected to the plug rod. A tension spring is sleeved on the arc surface of the plug rod. The two ends of the tension spring are fixedly connected to the plug rod and the connecting plate, respectively. A sliding rod is fixedly connected to the lower surface of the base. A slip ring is slidably connected to the arc surface of the sliding rod. A connecting block is fixedly connected to the slip ring near the servo motor. The connecting block is connected to the servo motor. The servo motor is connected to the transmission wheel through a transmission belt.

[0008] The effect achieved by the above components is as follows: when the tension of the transmission belt needs to be adjusted by adjusting the position of the servo motor, the plug rod is pulled to move, the plug rod drives the tension spring to stretch, and then the plug rod separates from the insertion hole. Then the connecting plate is pulled to move, the connecting plate drives the servo motor to move, the servo motor drives the slider to move, the slider slides on the inner wall of the slide groove, the servo motor drives the connecting block to move, the connecting block drives the slip ring to move, the slip ring slides on the arc surface of the slide rod, and after moving to the appropriate position, the plug rod is aligned with the insertion hole. Then the plug rod tension spring is released to retract and drive the plug rod to be inserted into the insertion hole for fixation.

[0009] Preferably, a spring is provided inside the slide groove, and the two ends of the spring are fixedly connected to the slider and the slide groove, respectively.

[0010] The effect achieved by the above components is that the spring's rebound force can drive the servo motor to move, and the servo motor drives the transmission belt to tighten quickly.

[0011] Preferably, a limiting rod is fixedly connected inside the slide groove, the limiting rod is slidably connected to the slider, and the spring is sleeved on the arc surface of the limiting rod.

[0012] The effect achieved by the above components is that the limiting rod can limit the spring, prevent the spring from deforming during use, and improve the service life of the spring.

[0013] Preferably, a handle is fixedly connected to the end of the insertion rod away from the insertion hole, and the handle is a plastic rod.

[0014] The effects achieved by the above components are: the relatively low cost of plastic materials can reduce the manufacturing cost of the handlebar, and the handlebar can drive the two inserts to move, avoiding the need to pull the inserts one by one.

[0015] Preferably, the bracket has an auxiliary structure on the side away from the transmission wheel. The auxiliary structure includes two fixed rods, which are fixedly connected to the bracket. A sliding frame is slidably connected to the surface of the fixed rods. A connecting plate is fixedly connected to the side of the two sliding frames that are close to each other. A storage box is fixedly connected to the end of the two connecting plates that are close to each other. A screw is threadedly connected to the side of the sliding frame away from the storage box, and the screw abuts against the fixed rod.

[0016] The effect achieved by the above components is as follows: when it is necessary to place the storage box to collect exposed materials, pull the storage box to move it. The storage box moves the connecting plate, which in turn moves the sliding frame. Then, align the sliding frame with the fixing rod, insert the sliding frame into the fixing rod, and the sliding frame moves the screw. After moving to the appropriate position, tighten the screw to fix it.

[0017] Preferably, the cross-section of the fixing rod is rectangular, and the fixing rod is a stainless steel rod.

[0018] The effect achieved by the above components is that the stainless steel material can increase the service life of the fixing rod and prevent the fixing rod from rusting during use.

[0019] Preferably, a handle is fixedly connected to the side of the storage box away from the bracket, and the handle has a "U" shaped cross-section.

[0020] The effect achieved by the above components is that when the storage box needs to be moved, the bracket pulls the handle, and the handle moves the storage box, making it more convenient to move the storage box.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by adjusting the structure, the existing technology addresses the issue that both excessively loose and excessively tight belts can lead to reduced transmission efficiency. Excessive looseness can cause slippage, while excessive tightness can increase friction, affecting the operating efficiency of the motor and transmission disc. Inappropriate belt tension can also cause excessive wear on equipment components such as the motor, transmission disc, and pulleys, reducing their lifespan and increasing maintenance costs. This device allows for convenient adjustment of the servo motor's height and prevents loosening when connecting the servo motor to the transmission pulley. The belt can be tightened by adjusting the servo motor for operation.

[0023] In this invention, by operating the auxiliary structure, the concrete overflowing during mixing and the material leaking out during feeding can be conveniently collected and used. Attached Figure Description
