Description

Technical Field

[0001] This utility model belongs to the field of grease injection technology, specifically a grease injection device. Background Technology

[0002] Grease is a thick, oily, semi-solid substance used in the friction parts of machinery for lubrication and sealing. It is also used on metal surfaces to fill gaps and prevent rust. Grease injection is a process in which high-viscosity grease is precisely pressurized and delivered to the friction parts or lubrication points of mechanical equipment through a specialized grease injection device (such as an electric, pneumatic, or manual pump) to form a long-lasting lubricating film, reduce wear, and prevent corrosion. The process involves grease storage, pressurization, delivery, and control. Grease is widely used in industrial equipment, automobiles, wind power, and other fields, and can effectively extend equipment life and improve operational reliability.

[0003] In existing technologies, during the grease injection process, the grease in the tank is prone to solidification due to long-term storage, which increases the transport resistance, affects the discharge speed of the grease, and may even cause blockage, thereby reducing the injection efficiency.

[0004] Therefore, this utility model provides a grease injection device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A grease injection device of this utility model includes a tank; a cover plate is hinged to the top of the tank, and an inlet is connected to the top of the cover plate; an outlet is connected to one side of the tank, and a grease injection assembly is connected to one end of the outlet; a motor is fixedly connected to the bottom of the tank, and a straight shaft is fixedly connected to the top of the motor; the straight shaft is rotatably connected to the tank; multiple agitator plates are fixedly connected to the outside of the straight shaft; during operation, grease is poured into the tank from the inlet for storage, and grease is output from the outlet; when adding grease to instruments, the grease injection assembly is activated; the grease injection assembly includes interconnected one-way valves. Specialized pumps, hoses, and nozzles are used to transfer grease from the container to the designated location. During this process, the motor starts, driving the linear shaft to rotate, which in turn drives the agitator plate to rotate within the container. The agitator plate stirs the grease, reducing the risk of it solidifying and maintaining its fluidity, thus minimizing the impact on the efficiency of grease application to instruments.

[0007] Preferably, multiple support rods are fixedly connected to the outside of the stirring plate. A rotating block is rotatably connected to one end of each support rod, and multiple stirring rods are fixedly connected to the outside of the rotating block. During operation, the stirring plate rotates inside the tank to agitate the grease. During this process, the support rods also extend into the grease. The rotating block is rotatably connected to the support rods. When the stirring plate rotates, the stirring rods, encountering resistance in contact with the grease, also move, thereby causing the rotating block to rotate, achieving a further agitation effect on the grease. Working together with the stirring plate, the agitation efficiency of the grease is accelerated, and the solidification of the grease is reduced. The support rods extend the distance of the stirring plate, allowing the grease closer to the inner wall of the tank to also be agitated, maintaining the fluidity of the grease. By setting up support rods, rotating blocks, and stirring rods to further agitate the grease, the agitation efficiency of the grease is improved.

[0008] Preferably, a heating plate is provided on the outer side of the stirring rod. The heating plate is fixedly connected to the tank body. During operation, the heating plate is installed on the inner side of the tank body. After the heating plate is activated, it heats the grease inside, thereby increasing the fluidity of the grease and reducing the phenomenon of grease solidification. In conjunction with the stirring plate, rotating block and stirring rod, the heated grease is stirred more evenly, so that the grease in the tank body is heated evenly, thereby improving the grease injection efficiency and reducing the possibility of blockage in the grease injection component.

[0009] Preferably, the bottom of the cover plate is provided with heat insulation cotton, which is fixedly connected to the tank body. During operation, the heat insulation cotton is connected to the outside of the tank body to keep the inside of the tank warm and reduce the situation where the heat inside the tank is lost too quickly.

[0010] Preferably, an observation window is provided on one side of the heating plate. The observation window is fixedly connected to the tank body. The observation window is made of transparent material. During operation, the observation window facilitates observation of the grease level in the tank body, enabling timely replenishment of grease and reducing the risk of cavitation in the grease injection assembly.

[0011] Preferably, the observation window is provided with multiple scale bars on its outer side. The scale bars are fixedly connected to the observation window. During operation, the scale bars can indicate the amount of lubricating grease used in the tank and also facilitate quantitative calculation.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The grease injection device of this utility model, by setting a motor to drive a straight shaft and a stirring plate to rotate, so that the stirring plate stirs the grease in the tank, reducing the phenomenon of grease solidification, maintaining the fluidity of grease, and improving the efficiency of grease injection on instruments.

[0014] 2. The grease injection device of this utility model further agitates the grease by setting a support rod, a rotating block, and a stirring rod, thereby improving the agitation efficiency of the grease. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 2As shown in the embodiment of this utility model, a grease injection device includes a tank 1; a cover plate 11 is hinged to the top of the tank 1, and an inlet 12 is connected to the top of the cover plate 11; an outlet 13 is connected to one side of the tank 1, and a grease injection assembly 14 is connected to one end of the outlet 13; a motor 15 is fixedly connected to the bottom of the tank 1, and a straight shaft 16 is fixedly connected to the top of the motor 15; the straight shaft 16 is rotatably connected to the tank 1; and multiple agitator plates 17 are fixedly connected to the outside of the straight shaft 16. During operation, grease is injected into the tank 1 from the inlet 12 for storage, and grease is output from the outlet 13. When grease is applied to instruments, the grease injection assembly 14 is activated. The grease injection assembly 14 includes interconnected one-way valves, Specialized pumps, hoses, and nozzles are used to transfer grease from tank 1 to designated locations. During this process, motor 15 starts, driving the linear shaft 16 to rotate, which in turn drives the agitator 17 to rotate within tank 1. The agitator 17 agitates the grease within tank 1, reducing the risk of grease solidification due to prolonged settling time, which could lead to blockage of the grease injection assembly 14 and consequently, low grease transfer efficiency. By configuring motor 15 to drive the linear shaft 16 and agitator 17 to rotate, the agitator 17 agitates the grease within tank 1, reducing the likelihood of grease solidification, maintaining grease fluidity, and minimizing the impact on the efficiency of grease injection into instruments.

[0024] like Figures 1 to 3 As shown, multiple support rods 2 are fixedly connected to the outside of the stirring plate 17. A rotating block 21 is rotatably connected to one end of each support rod 2. Multiple stirring rods 22 are fixedly connected to the outside of the rotating block 21. During operation, the stirring plate 17 rotates inside the tank 1 to agitate the grease. During this process, the support rods 2 also extend into the grease. The rotating block 21 is rotatably connected to the support rods 2. When the stirring plate 17 rotates, the stirring rods 22 will also move due to resistance in contact with the grease, thereby causing the rotating block 21 to rotate, achieving a further agitation effect on the grease. Working together with the stirring plate 17, the agitation efficiency of the grease is accelerated, and the solidification of the grease is reduced. The support rods 2 extend the distance of the stirring plate 17, so that the grease closer to the inner wall of the tank 1 can also be agitated, maintaining the fluidity of the grease. By setting the support rods 2, rotating block 21, and stirring rods 22 to further agitate the grease, the agitation efficiency of the grease is improved.

[0025] like Figures 1 to 5As shown, a heating plate 3 is provided on the outside of the stirring rod 22. The heating plate 3 is fixedly connected to the tank body 1. During operation, the heating plate 3 is installed on the inside of the tank body 1. After the heating plate 3 is activated, it will heat the grease inside, thereby increasing the fluidity of the grease and reducing the phenomenon of grease solidification. In conjunction with the stirring plate 17, the rotating block 21, and the stirring rod 22, the heated grease is stirred more evenly, so that the grease in the tank body 1 is heated evenly, thereby improving the grease injection efficiency and reducing the possibility of blockage in the transmission of the grease injection component 14.

[0026] like Figures 1 to 5 As shown, the bottom of the cover plate 11 is provided with heat insulation cotton 4, which is fixedly connected to the tank body 1. During operation, the heat insulation cotton 4 is connected to the outside of the tank body 1 to keep the inside of the tank body 1 warm and reduce the situation where the heat inside the tank body 1 is lost too quickly.

[0027] like Figures 1 to 5 As shown, an observation window 5 is provided on one side of the heating plate 3. The observation window 5 is fixedly connected to the tank 1. The observation window 5 is made of transparent material. During operation, the observation window 5 facilitates observation of the grease condition in the tank 1, enabling timely replenishment of grease and reducing the occurrence of air extraction in the grease injection assembly 14.

[0028] like Figure 1 As shown, the observation window 5 is provided with multiple scale bars 6 on its outer side. The scale bars 6 are fixedly connected to the observation window 5. During operation, the scale bars 6 can indicate the amount of lubricating grease used in the tank 1 and also facilitate quantitative calculation.

[0029] Working principle: Grease is poured into tank 1 through inlet 12 for storage and discharged through outlet 13. When grease is added to the instrument, grease injection assembly 14 is activated. Grease injection assembly 14 includes interconnected one-way valves, a dedicated pump, hoses, and nozzles, etc., to transfer the grease in tank 1 and add it to the designated location. During this process, motor 15 starts, which drives the linear shaft 16 to rotate, thereby driving the agitator 17 to rotate inside tank 1. The agitator 17 agitates the grease in tank 1, reducing the grease's tendency to stand for too long, which can lead to increased adhesion and cause the grease injection assembly 14 to malfunction. Blockage can occur, leading to inefficient grease delivery. To address this, motor 15 drives the linear shaft 16 and agitator 17 to rotate. The agitator 17 stirs the grease in the container 1, reducing grease solidification and maintaining its fluidity. This minimizes the impact on the efficiency of grease application to instruments. As the agitator 17 rotates within the container 1, stirring the grease, the support rod 2 extends into the grease. The rotating block 21 is rotatably connected to the support rod 2. When the agitator 17 rotates, the stirring rod 22, encountering resistance in contact with the grease, also moves, thereby driving the rotating block 21... The rotation of the rod further agitates the grease, working in conjunction with the agitator 17 to accelerate the agitation and reduce solidification. The support rod 2 extends the distance of the agitator 17, ensuring that the grease closer to the inner wall of the tank 1 is also agitated, maintaining its fluidity. The support rod 2, rotating block 21, and agitator 22 further agitate the grease, improving agitation efficiency. The heating plate 3, installed inside the tank 1, heats the grease upon activation, further increasing its fluidity and reducing solidification. The stirring plate 17, rotating block 21, and stirring rod 22 are used to stir the heated grease more evenly, making the grease in the tank 1 heated evenly, thereby improving the grease injection efficiency and reducing the possibility of blockage in the grease injection component 14. The heat insulation cotton 4 is connected to the outside of the tank 1 to keep the inside of the tank 1 warm and reduce the possibility of too fast heat loss in the tank 1. The observation window 5 makes it easy to observe the grease in the tank 1 and replenish the grease in time to reduce the possibility of the grease injection component 14 being pulled dry. The scale bar 6 makes it easy to indicate the amount of grease used in the tank 1 and also facilitates quantitative calculation.
