Description

Technical Field

[0001] The invention relates to the technical field of agricultural waste treatment, in particular to a chain mixer. Background Art

[0002] As an efficient and multifunctional agricultural machinery, the chain mixer has played an indispensable role in agricultural production. Its working principle is mainly to drive the mixing blades and rotating shafts through chain transmission to mix, stir and grind various agricultural raw materials such as fertilizers, feeds, pesticides, etc. The application of this machinery has greatly improved the efficiency of agricultural production, reduced costs and improved product quality.

[0003] However, in actual use, the chain mixer has also exposed some defects, among which the most prominent one is the noise pollution problem. During the operation of the traditional chain mixer, due to the friction and collision of the chain, blades and other parts, a lot of noise will be generated. This noise not only affects the working environment, but also may cause damage to the hearing of the operator. Operators who are in a high-noise environment for a long time may experience symptoms of occupational diseases such as hearing loss and tinnitus, which may even affect their physical health and work efficiency in severe cases.

[0004] The noise pollution problem is not only related to the health of operators, but may also cause other harms to agricultural production. First, the noise will interfere with the operator's attention, making it difficult for them to accurately judge the operating status and mixing effect of the mixer, thus affecting production quality and efficiency. Secondly, a long-term high noise environment may also have an adverse effect on the crops around the mixer and interfere with their normal growth. Finally, the noise may also cause trouble to the lives of surrounding residents, causing complaints and disputes, which is not conducive to the harmonious and stable development of agricultural production.

[0005] Therefore, it is urgent to research and develop a chain mixer that can reduce noise pollution and solve the above-mentioned technical problems. Summary of the invention

[0006] The present invention aims to provide a chain mixer, which can reduce the noise generated when the mixer is in operation.

[0007] In order to achieve the above object, the present invention provides a chain mixer, the specific implementation scheme is as follows:

[0008] A chain mixer comprises a frame, a stirring tank is arranged in the frame, a stirring assembly is arranged in the stirring tank, a driving assembly is arranged on the frame and is connected to the stirring assembly, and the stirring assembly is driven by the driving assembly to rotate in the stirring tank along the circumferential direction of the frame;

[0009] A soundproof cover is provided on the frame, and the drive assembly is covered by the soundproof cover in a soundproof area formed by the soundproof cover and the outer wall of the frame;

[0010] A shock absorbing assembly is provided on the frame at a position within the sound insulation area, and the driving assembly is mounted on the shock absorbing assembly.

[0011] Compared with the prior art, the chain mixer of the present invention provides a stirring assembly in a stirring tank of a frame of the chain mixer, and stirs and mixes the agricultural waste entering the stirring tank under the driving action of a driving assembly on the frame. During the entire stirring process, the driving assembly is covered by a soundproof cover and arranged in a soundproof area formed between the soundproof cover and the frame, which can reduce the degree of transmission of noise generated by the driving assembly in the process of driving the stirring assembly to the outside world, and a shock-absorbing assembly is installed on the frame, and the driving assembly is installed using the shock-absorbing assembly. The mechanical vibration generated during the operation of the driving assembly is buffered, reduced or even offset by the shock-absorbing assembly, thereby further reducing the degree of noise generation.

[0012] In some embodiments, the shock absorbing assembly includes a shock absorbing frame, a shock absorbing rod and a shock absorbing platform, the shock absorbing frame is connected to the frame, the shock absorbing platform is arranged on the shock absorbing frame, the shock absorbing rod is arranged between the shock absorbing platform and the shock absorbing frame, the bottom end of the shock absorbing rod passes through the shock absorbing frame and is movably connected with the shock absorbing frame, the shock absorbing spring is sleeved on the shock absorbing rod, one end of the shock absorbing spring abuts against the shock absorbing frame, and the other end abuts against the shock absorbing platform.

[0013] A shock absorbing platform is arranged on a shock absorbing frame, and the shock absorbing platform is movably connected with the shock absorbing frame through a shock absorbing rod and a shock absorbing spring structure arranged on the shock absorbing rod is used as a shock absorbing component. When a driving component is arranged on the shock absorbing platform, the mechanical vibration generated by the operation of the driving component acts on the shock absorbing platform, and the shock absorbing platform is transmitted to the shock absorbing rod. The shock absorbing rod compresses the shock absorbing spring, and the shock absorbing spring elastically deforms to absorb and disperse the vibration energy, thereby reducing the spread of mechanical vibration and noise, thereby reducing the noise generated when the chain mixer is in operation.

[0014] In some of the embodiments, a shock absorbing gasket is provided on the shock absorbing platform, and the driving assembly is provided on the shock absorbing gasket and connected to the shock absorbing platform.

[0015] By arranging shock-absorbing pads on the shock-absorbing platform, the vibration energy can be effectively absorbed and dispersed, thereby reducing the spread of mechanical vibration and noise.

[0016] In some embodiments, the sound insulation cover includes an inner layer, a middle layer and an outer layer, the inner layer and the frame form the sound insulation area, the middle layer is wrapped around the outer peripheral wall of the inner layer, and the outer layer is wrapped around the outer peripheral wall of the middle layer.

[0017] The sound insulation cover is provided with a structure including an inner layer, a middle layer and an outer layer, so that the sound insulation effect of the sound insulation cover is improved.

[0018] In some embodiments, the inner layer is a porous foam plastic layer, the middle layer is a glass wool layer, and the outer layer is a metal plate layer.

[0019] By using a porous foam plastic layer as the inner layer, it can absorb sound waves and convert them into heat energy, thereby reducing the spread of noise. Using a glass wool layer as the middle layer can effectively block the propagation of sound waves and further reduce the noise level. Using a metal plate layer as the outer layer can prevent the sound insulation cover from being eroded and damaged by the external environment.

[0020] In some embodiments, the driving assembly includes a driving motor, a transmission chain and a reduction gearbox. The driving motor is disposed on the shock absorbing platform, the motor shaft of the driving motor is drivingly connected to the reduction gearbox, the reduction gearbox is drivingly connected to the transmission chain, and the transmission chain is drivingly connected to the stirring assembly; or the motor shaft of the driving motor is drivingly connected to the transmission chain, the transmission chain is drivingly connected to the reduction gearbox, and the reduction gearbox is drivingly connected to the stirring assembly.

[0021] By adopting a drive motor transmission to connect the reduction box and the transmission chain, it is ensured that the drive motor can drive the stirring mechanism to operate, thereby improving the driving stability of the drive component.

[0022] In some embodiments, the stirring assembly includes a rotating disk, a connecting shaft, a rotating shaft and stirring blades. The rotating disk is arranged in the stirring tank, the rotating shaft is arranged on the rotating disk, and a plurality of stirring blades are arranged on the outer peripheral wall of the rotating shaft. The connecting shaft is arranged in the stirring tank, one end of which is transmission connected to the rotating disk, and the other end of which is transmission connected to the reduction box or the transmission chain.

[0023] The driving assembly and the rotating disk are connected by a connecting shaft. The rotating disk is driven by a driving motor to rotate and drive the rotating shaft and the stirring blades on the rotating shaft to rotate to stir and mix the agricultural waste entering the stirring tank.

[0024] In some of the embodiments, a noise detection sensor is provided on the frame or the soundproof cover, and a controller is provided on or outside the frame, and the controller is electrically connected or communicatively connected to the noise detection sensor.

[0025] By arranging a noise detection sensor on the frame or the soundproof cover, the operating status and noise level of the mixer can be monitored in real time and transmitted to the controller.

[0026] In some embodiments, the controller includes a data acquisition module and a data analysis module. The data acquisition module receives and stores the detection data transmitted by the noise detection sensor. The data analysis module compares the preset standard data with the received detection data to evaluate the noise level.

[0027] By setting up a data acquisition module and a data analysis module on the controller, the reception, storage and comparison of noise detection data can be realized, thereby improving the accuracy of noise detection.

[0028] In some of the embodiments, an alarm is provided on the rack or the controller, and the alarm is electrically or communicatively connected to the controller.

[0029] By setting an alarm on the rack or controller, when the noise level is higher than the preset noise standard, the alarm is controlled to operate and sound an alarm, ensuring that the operator can perform maintenance on the sound insulation of the chain mixer in time.

[0030] Based on the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0031] A stirring assembly is arranged in a stirring tank of a frame of a chain mixer, and the agricultural waste entering the stirring tank is stirred and mixed by the stirring assembly under the driving action of a driving assembly on the frame. During the whole stirring process, the driving assembly is covered by a soundproof cover in a soundproof area formed between the soundproof cover and the frame, which can reduce the degree of noise generated by the driving assembly in the process of driving the stirring assembly and transmitted to the outside world. In addition, a shock-absorbing assembly is installed on the frame, and the driving assembly is installed using the shock-absorbing assembly. The mechanical vibration generated during the operation of the driving assembly is buffered, reduced or even offset by the shock-absorbing assembly, thereby further reducing the degree of noise generation.
