Technical Field

[0001] This utility model relates to the field of concrete mixers, specifically a shock-absorbing concrete mixer that facilitates material discharge. Background Technology

[0002] A concrete mixer is a machine that mixes cement, sand, aggregate, and water to produce concrete. It mainly consists of a mixing drum, feeding and discharging mechanisms, a water supply system, a prime mover, a transmission mechanism, a frame, and support devices. Based on working characteristics, it can be classified as intermittent (batch) or continuous; based on mixing principle, it can be classified as gravity-fed or forced-mixed; based on installation method, it can be classified as fixed or mobile; based on discharge method, it can be classified as tilting or non-tilting; and based on mixing drum structure, it can be classified as pear-type, drum-type, double-cone, disc vertical shaft type, and groove horizontal shaft type, etc.

[0003] In the existing technology, a concrete mixer is a mechanical device used to mix raw materials such as cement, sand, water and admixtures in a certain proportion and stir them into uniform concrete that meets the engineering requirements. The concrete mixer mainly mixes by rotating the mixing drum and then discharges the concrete by pushing the blades. However, since the mixing drum of the concrete mixer is placed horizontally, some concrete is easily left inside the mixer when the concrete is discharged, which leads to waste. Utility Model Content

[0004] To address the shortcomings of existing technologies, since the mixing drum of a concrete mixer is placed horizontally, some concrete tends to remain inside the mixer during discharge, leading to waste. This invention proposes a shock-absorbing concrete mixer that facilitates discharge.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a shock-absorbing concrete mixer that facilitates material discharge, including a concrete mixer, wherein the bottom of the concrete mixer is provided with an inclined mechanism.

[0006] The tilting mechanism includes an L-shaped base plate located at the bottom of the concrete mixer. A connecting plate is hinged to the top of the L-shaped base plate, and the top of the connecting plate is fixedly connected to the bottom of the concrete mixer. A first fixing plate is fixedly connected to the top of the L-shaped base plate, and a motor is fixedly connected to one side of the first fixing plate. The output shaft of the motor passes through one side of the first fixing plate and is fixedly connected to a first bevel gear. A second fixing plate is fixedly connected to the top of the L-shaped base plate, and an L-shaped rotating plate is rotatably connected to one side of the second fixing plate. A second bevel gear is rotatably connected to one side of the L-shaped rotating plate, and the teeth of the second bevel gear mesh with the teeth of the first bevel gear. A threaded rod is threadedly connected to the inner cavity of the L-shaped rotating plate and the second bevel gear. A concave block is fixedly connected to the bottom of the connecting plate, and the surface of the threaded rod is rotatably connected to the inner cavity of the concave block via a rotating shaft.

[0007] Preferably, a spring is fixedly connected to the bottom of the L-shaped base plate, a placement plate is fixedly connected to the bottom of the spring, a damper is fixedly connected to the top of the placement plate, and the top of the damper is fixedly connected to the bottom of the L-shaped base plate.

[0008] Preferably, a limiting groove is formed on the surface of the second fixing plate, and a T-shaped rotating block is rotatably connected to the inner cavity of the limiting groove. One side of the T-shaped rotating block is fixedly connected to one side of the L-shaped rotating plate.

[0009] Preferably, a fixing block is fixedly connected to one side of the threaded rod, and the diameter of the fixing block is larger than the diameter of the threaded rod.

[0010] Preferably, a support block is fixedly connected to the top of the L-shaped base plate, and a rubber block is provided at the bottom of the connecting plate, with the bottom of the rubber block fixedly connected to the top of the support block.

[0011] Preferably, a reinforcing rod is fixedly connected to one side of the second fixing plate, and the bottom of the reinforcing rod is fixedly connected to the top of the L-shaped base plate.

[0012] Preferably, the surface of the motor is provided with a protective shell, and one side of the protective shell is fixedly connected to one side of the first fixing plate.

[0013] The advantages of this utility model are:

[0014] This invention relates to a motor that drives a second bevel gear via a first bevel gear. The second bevel gear then moves a threaded rod, which rotates inside a concave block. As the threaded rod moves, it pushes the connecting plate and the concrete mixer to tilt via the concave block. This tilting allows the concrete to slide out through the inclined surface and gravity when discharging, preventing excessive residue and reducing waste. Furthermore, the vibrations generated during operation are absorbed by the connecting plate and L-shaped base plate above the spring, which in turn absorbs the vibrations, thus damping the concrete mixer and making it more stable. The L-shaped base plate also compresses the damper, preventing rebound when the spring returns to the L-shaped base plate. This solves the problem of concrete residue remaining inside the horizontally placed mixing drum, leading to waste. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a vibration-damping concrete mixer that facilitates material discharge. (See also...) Figure 1-6 A shock-absorbing concrete mixer for easy discharge includes a concrete mixer 1, with an inclined mechanism 2 at the bottom of the concrete mixer 1. The concrete mixer 1 can be used to manufacture concrete. The concrete mixer 1 is mainly composed of a power system, a mixing system, a support system, a control system, and a safety protection system. Cement, sand, gravel, water, and additives are fed into the mixing drum through the feed inlet according to a preset ratio. Then, the mixing shaft drives the blades inside the mixing drum to rotate at high speed, achieving rapid and uniform mixing. After mixing is completed, the discharge port opens, and the concrete is discharged under the push of the blades.

[0026] The tilting mechanism 2 includes an L-shaped base plate 201, located at the bottom of the concrete mixer 1. A connecting plate 202 is hinged to the top of the L-shaped base plate 201 via a hinge. The top of the connecting plate 202 is fixedly connected to the bottom of the concrete mixer 1. A first fixing plate 203 is fixedly connected to the top of the L-shaped base plate 201. A motor 204 is fixedly connected to one side of the first fixing plate 203. The output shaft of the motor 204 extends through one side of the first fixing plate 203. A first bevel gear 205 is fixedly connected to the output shaft of the motor 204. A second fixing plate 206 is fixedly connected to the top of the base plate 201. An L-shaped rotating plate 207 is rotatably connected to one side of the second fixing plate 206. A second bevel gear 208 is rotatably connected to one side of the L-shaped rotating plate 207. The teeth of the second bevel gear 208 mesh with the teeth of the first bevel gear 205. A threaded rod 209 is threadedly connected to the inner cavity of the L-shaped rotating plate 207 and the second bevel gear 208. A concave block 210 is fixedly connected to the bottom of the connecting plate 202. The surface of the threaded rod 209 is rotatably connected to the inner cavity of the concave block 210 through a rotating shaft.

[0027] The L-shaped base plate 201 is located at the bottom of the concrete mixer 1. Its upper side can be used to connect to the connecting plate 202, allowing the connecting plate 202 to rotate. The connecting plate 202 is connected to the concrete mixer 1, enabling the concrete mixer 1 to rotate as well. The first fixing plate 203 can be used to support the motor 204, ensuring the motor 204 is stable on one side of the first fixing plate 203. The motor 204 can drive the first bevel gear 205 to rotate. The second fixing plate 206 can be used to support the L-shaped rotating plate 207, allowing the L-shaped rotating plate 207 and the second bevel gear 208 to rotate on one side of the first bevel gear 205. The L-shaped rotating plate 207 can be used to connect to the second bevel gear 208, allowing the second bevel gear 208 to be positioned on one side of the first bevel gear 205. This allows... When the first bevel gear 205 rotates, it can drive the second bevel gear 208 to rotate together. The threaded rod 209 is located inside the second bevel gear 208 and can be moved by the rotating second bevel gear 208. The concave block 210 can be connected to the connecting plate 202 and the threaded rod 209, so that when the threaded rod 209 moves, it can squeeze and drive the connecting plate 202 and the L-shaped base plate 201 to tilt. The L-shaped rotating plate 207 can rotate on one side of the second fixed plate 206, so that the second bevel gear 208, the threaded rod 209 and the concrete mixer 1 can tilt together. At this time, the tilted concrete mixer 1 can discharge concrete while allowing the internal concrete to slide out through the inclined surface and gravity, without leaving too much residue, thus reducing waste.

[0028] Reference Figure 4A spring 4 is fixedly connected to the bottom of the L-shaped base plate 201, a placement plate 3 is fixedly connected to the bottom of the spring 4, and a damper 5 is fixedly connected to the top of the placement plate 3. The top of the damper 5 is fixedly connected to the bottom of the L-shaped base plate 201. The placement plate 3 is located at the bottom of the L-shaped base plate 201 and can be connected to the L-shaped base plate 201 through the spring 4. This allows the vibration of the concrete mixer 1 during use to be absorbed by the elastic force of the spring 4, thereby playing a shock absorption role for the concrete mixer 1 and making the concrete mixer 1 more stable. The damper 5 can play a damping role, so that when the spring 4 returns to the L-shaped base plate 201, the L-shaped base plate 201 and the concrete mixer 1 will not rebound.

[0029] Reference Figure 3 A limiting groove 6 is provided on the surface of the second fixed plate 206. A T-shaped rotating block 7 is rotatably connected to the inner cavity of the limiting groove 6. One side of the T-shaped rotating block 7 is fixedly connected to one side of the L-shaped rotating plate 207. The inside of the limiting groove 6 can be used to place the T-shaped rotating block 7, and the L-shaped rotating plate 207 can be reinforced by the T-shaped rotating block 7, so that the L-shaped rotating plate 207 is not easy to detach from the second fixed plate 206 when rotating on one side of the second fixed plate 206.

[0030] Reference Figure 5 A fixing block 8 is fixedly connected to one side of the threaded rod 209. The diameter of the fixing block 8 is larger than the diameter of the threaded rod 209. The fixing block 8 can limit the threaded rod 209, so that the threaded rod 209 is less likely to disengage from the second bevel gear 208 when it moves inside the second bevel gear 208.

[0031] Reference Figure 4 A support block 9 is fixedly connected to the top of the L-shaped base plate 201, and a rubber block 10 is provided at the bottom of the connecting plate 202. The bottom of the rubber block 10 is fixedly connected to the top of the support block 9. The support block 9 can support one side of the bottom of the connecting plate 202, making the connecting plate 202 more stable on the upper side of the L-shaped base plate 201. The rubber block 10 can also act as a buffer, reducing noise when the connecting plate 202 presses on the upper side of the support block 9.

[0032] Reference Figure 3 A reinforcing rod 11 is fixedly connected to one side of the second fixing plate 206. The bottom of the reinforcing rod 11 is fixedly connected to the top of the L-shaped base plate 201. The reinforcing rod 11 can reinforce the second fixing plate 206, making the second fixing plate 206 more secure on the upper side of the L-shaped base plate 201 and less prone to breakage or damage.

[0033] Reference Figure 3The surface of the motor 204 is provided with a protective shell 12. One side of the protective shell 12 is fixedly connected to one side of the first fixing plate 203. The protective shell 12 can protect the motor 204, making it less likely for the motor 204 to be damaged by foreign objects on the side of the first fixing plate 203, and also less likely to get contaminated with concrete.

[0034] Working Principle: When using this device, concrete is first produced using the concrete mixer 1. When the concrete needs to be discharged, the motor 204 is started to drive the first bevel gear 205 to rotate. The first bevel gear 205 drives the second bevel gear 208 to rotate together, which in turn drives the threaded rod 209 to move. Simultaneously, the threaded rod 209 rotates inside the concave block 210. At the same time, the threaded rod 209 also drives the second bevel gear 208 and the L-shaped rotating plate 207 to rotate together. The L-shaped rotating plate 207 rotates on one side of the second fixed plate 206, and the second bevel gear 208 also rotates on the surface of the first bevel gear 205. When the threaded rod 209 moves, it pushes the connecting plate 202 and the concrete mixer 1 to tilt through the concave block 210. This causes the concrete mixer 1 to discharge... During concrete mixing, the concrete can be tilted to allow it to slide out through the slope and gravity, preventing excessive residue and reducing waste. Furthermore, the vibrations generated during operation of the concrete mixer 1 are absorbed by the connecting plate 202 and the L-shaped base plate 201 above the spring 4. The spring 4 absorbs these vibrations through its elasticity, thus damping the concrete mixer 1 and making it more stable. Simultaneously, the L-shaped base plate 201 compresses the damper 5, ensuring its damping effect. This prevents the L-shaped base plate 201 and the concrete mixer 1 from rebounding when the spring 4 returns to its original position. This solves the problem of some concrete remaining inside the concrete mixer 1 when it is discharged, which is often due to the horizontal placement of the mixing drum, leading to waste.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
