[0001] This utility model belongs to the technical field of dust removal equipment, specifically relating to a dust removal device for processing total mixed rations for dairy cows. Background Technology

[0002] Total Mixed Ration (TMR) mixing equipment is a core piece of machinery in livestock farming. It is mainly used to uniformly mix roughage, concentrate, and various nutritional additives into a nutritionally balanced diet. The TMR mixing equipment in the ranch is stationary and has a fixed operating workshop. The workshop is in a semi-enclosed state. Because there are many types of feed used to feed dairy cows, consisting of hay and concentrate, a forklift is needed to add various feed ingredients into the TMR mixing equipment during the feeding process.

[0003] In actual use, the feeding of materials by the forklift and the mixing of hay will generate a lot of dust. Workers who are in this environment for a long time will suffer from health problems. There is a lack of dust removal devices for processing total mixed rations for dairy cows. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device for processing total mixed rations (TMR) for dairy cows, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for processing total mixed ration (TMR) for dairy cows, comprising a TMR mixer and a dust removal mechanism. The dust removal mechanism includes a housing, with a partition installed inside the housing. Multiple through-hole mounting cylinders are installed on the partition, and a connected filter bag is installed at the bottom end of each mounting cylinder. A negative pressure fan for creating negative pressure above the mounting cylinders is installed on the housing. The outer side of the filter bag is connected to the top of the interior of the TMR mixer.

[0006] The housing is connected to a backflushing mechanism, which includes an air supply pipe. Inside the housing, above the partition, is an air supply pipe for supplying air. Each air supply pipe has a connecting branch pipe above each mounting cylinder. The bottom end of the branch pipe is slidably connected to a sliding pipe. A spring is installed between the sliding pipe and the branch pipe. The sliding pipe has a connecting groove, and the bottom end of the sliding pipe communicates with the interior through the connecting groove. The bottom end of the sliding pipe is used to abut against and block the top end of the mounting cylinder.

[0007] In a preferred embodiment, the bottom end of the sliding tube is disc-shaped, and the top end of the mounting cylinder is provided with a groove. The disc-shaped bottom end of the sliding tube extends into the groove and abuts against the mounting cylinder to block it.

[0008] In a preferred embodiment, a connecting pipe is installed at one end of the filter bag in the housing, and an extraction pipe is installed at the top of the TMR mixer. The other end of the extraction pipe is installed on the connecting pipe, and the outside of the filter bag is connected to the top of the interior of the TMR mixer through the connecting pipe and the extraction pipe.

[0009] In a preferred embodiment, an air compressor is installed on the outside of the housing, one end of the air supply pipe is installed on the air tank of the air compressor, the air supply pipe is connected to the air tank of the air compressor, and a solenoid valve is installed on the air supply pipe.

[0010] In a preferred embodiment, the bottom of the box has an open funnel-shaped structure, and a cover plate for closing is rotatably connected to the bottom of the box.

[0011] In a preferred embodiment, a bracket is installed at the bottom of the box, and the bottom of the box is suspended by the bracket.

[0012] In a preferred embodiment, the plurality of mounting cylinders are arranged in a rectangular array, and the air supply pipes are provided in multiple forms.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a negative pressure fan to create a negative pressure state inside the housing, and a negative pressure is also created above the TMR mixer via the extraction pipe. This removes dust generated during the TMR mixing process. Filter bags intercept the dust. Activating the solenoid valve allows high-pressure gas to enter the branch pipe through the air supply pipe, pushing the sliding tube downwards. The sliding tube then seals the top of the mounting cylinder. The high-pressure gas enters the connecting groove and is ejected from the bottom, blowing air onto the filter bags. Under the high-pressure airflow, the filter bags rapidly expand and vibrate, blowing away the dust on their surface. The intermittent activation of the solenoid valve creates a pulsed airflow, effectively saving gas consumption and preventing excessive airflow from stirring up fallen dust. By sealing the top of the mounting cylinder, all the pulsed airflow enters the filter bags, preventing it from spreading to the top of the housing, reducing losses, and improving work efficiency.

[0024] Please see Figures 1-6 This utility model provides a dust removal device for processing total mixed ration (TMR) for dairy cows, including a TMR mixer 1 and a dust removal mechanism 2. The dust removal mechanism 2 includes a housing 24, with a partition 27 installed inside the housing 24. Multiple through-hole mounting cylinders 28 are installed on the partition 27. Filter bags 26 are installed at the bottom of the mounting cylinders 28, so that dust entering the housing 24 can only be filtered by the filter bags 26 and reach the top of the housing 24. A negative pressure fan 22 is installed on the housing 24 to create a negative pressure above the mounting cylinders 28. The outer side of the filter bags 26 is connected to the top of the TMR mixer 1, which facilitates the creation of a negative pressure inside the housing 24 and facilitates the extraction of dust from the TMR mixer 1.

[0025] A backflushing mechanism 3 is connected to the housing 24. The backflushing mechanism 3 includes an air supply pipe 33. An air supply pipe 33 for supplying air is installed inside the housing 24 above the partition 27. Each air supply pipe 33 is connected to a branch pipe 35 above each mounting cylinder 28. A sliding pipe 34 is slidably connected to the bottom end of the branch pipe 35. A spring 36 is installed between the sliding pipe 34 and the branch pipe 35. A connecting groove 38 is provided on the sliding pipe 34. The bottom end of the sliding pipe 34 is connected to the interior through the connecting groove 38, which facilitates the movement of the sliding pipe 34 by high-pressure gas. The bottom end of the sliding pipe 34 is used to abut and block the top end of the mounting cylinder 28, thereby reducing the outward spread of high-pressure gas.

[0026] Specifically, such as Figure 5 As shown, the bottom end of the sliding tube 34 is disc-shaped, and the top end of the mounting cylinder 28 is provided with a groove 37. The disc-shaped bottom end of the sliding tube 34 extends into the groove 37 and abuts against the mounting cylinder 28 to block it, which facilitates sealing.

[0027] Specifically, such as Figure 1 As shown, a connecting pipe 25 is installed at one end of the filter bag 26 in the housing 24, and an extraction pipe 21 is installed at the top of the TMR mixer 1. The other end of the extraction pipe 21 is installed on the connecting pipe 25. The outside of the filter bag 26 is connected to the top of the inside of the TMR mixer 1 through the connecting pipe 25 and the extraction pipe 21, so as to facilitate the formation of negative pressure in the TMR mixer 1 through the extraction pipe 21.

[0028] Specifically, such as Figure 2 As shown, an air compressor 32 is installed on the outside of the housing 24. One end of the air supply pipe 33 is installed on the air tank of the air compressor 32. The air supply pipe 33 is connected to the air tank of the air compressor 32. A solenoid valve 31 is installed on the air supply pipe 33 to provide high-pressure gas and control the operation of the high-pressure gas.

[0029] Specifically, such as Figure 3 As shown, the bottom of the box 24 has an open funnel-shaped structure, and the bottom of the box 24 is rotatably connected to a cover plate 4 for sealing, which facilitates the discharge of dust.

[0030] Specifically, such as Figure 2 As shown, a bracket 23 is installed at the bottom of the box 24, and the bottom of the box 24 is suspended by the bracket 23 to facilitate the collection and reception of dust.

[0031] Specifically, such as Figure 3 As shown, multiple mounting cylinders 28 are arranged in a rectangular array, and multiple air supply pipes 33 are provided, so that high-pressure gas can be delivered into each mounting cylinder 28.

[0032] The working principle and usage process of this utility model: The TMR mixer 1 is used for mixing and stirring forage. During operation, the cover plate 4 at the bottom of the housing 24 is closed, and the negative pressure fan 22 is started. The negative pressure fan 22 creates a negative pressure state inside the housing 24. Through the connecting pipe 25 and the extraction pipe 21, a negative pressure is formed above the inside of the TMR mixer 1, thereby removing the dust generated during the mixing process of the TMR mixer 1. The dust enters the interior of the housing 24 and is filtered by the filter bag 26, so that the dust is intercepted on the outside of the filter bag 26. Clean air is discharged through the negative pressure fan 22. After a period of use, the negative pressure fan 22 is turned off, the cover plate 4 is opened, and the air compressor 32 is started. The air compressor 32 generates high-pressure gas in the air tank. The solenoid valve 31 is activated to connect the air supply pipe 33 with the air tank of the air compressor 32. The high-pressure gas enters the branch pipe 35 through the air supply pipe 33. In the initial state, the spring 36 is in a contracted state, and the top of the connecting groove 38 is blocked by the outer wall of the branch pipe 35. The high-pressure gas exits from the bottom of the branch pipe 35. The gas is ejected, pushing the sliding tube 34 downward. The spring 36 is stretched, and the disc-shaped bottom end of the sliding tube 34 extends into the settling groove 37 and abuts against the mounting cylinder 28, thus sealing the top of the mounting cylinder 28. At this time, as the sliding tube 34 moves downward, the top of the connecting groove 38 connects with the bottom end of the branch pipe 35. High-pressure gas enters the connecting groove 38, is ejected through the bottom end of the connecting groove 38, and enters the mounting cylinder 28, blowing air onto the filter bag 26. Under the high-pressure airflow, the filter bag 26 rapidly expands and shakes, thereby removing dust from the surface of the filter bag 26. Dust is blown out by intermittently activating the solenoid valve 31, thereby forming a pulsed airflow to facilitate impact on the filter bag 26. The intermittent impact avoids excessive gas consumption and prevents excessive airflow from causing the fallen dust to be stirred up again. By sealing the top of the mounting cylinder 28, the pulsed airflow can be fully introduced into the filter bag 26, preventing it from spreading to the top of the housing 24, reducing losses, and improving working efficiency. The fallen dust is discharged through the funnel-shaped bottom of the housing 24, thus facilitating dust treatment.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
