Description

Technical Field

[0001] The utility model relates to the field of baling machines, in particular to a baling machine with a dust removal device. Background Art

[0002] A baler is a commonly used agricultural machinery and equipment, which is used to bale forage, straw and the like of crops. For example, a pre-pressing chamber of a round baler with patent number CN214338752U is provided. In this patent, an upper conveying system, a forced conveying system, a rotating roller mechanism and the like are arranged to cooperate with each other, so that the baler can achieve continuous feeding, and the baler can operate non-stop, thus saving time and improving work efficiency.

[0003] Through research and analysis, it is found that when the above-cited patent performs baling operations on forage, straw, etc., since the pre-pressing chamber of the round baler is not equipped with a dust suction device, during the baling process, the forage passes through the channel from the feeding system into the baling chamber, and a certain amount of dust may be generated in this process. Specifically, when the forage is conveyed along the channel, due to friction and impact, the forage may scatter fine particles and debris dust. These dust particles may accumulate in the channel and the baling chamber, and may be emitted into the surrounding environment through the ventilation system. Especially under long-term use, the accumulation of dust may cause dust pollution in the environment and affect the health of the operator. Therefore, it is necessary to improve the shortcomings and defects of the prior art. Utility Model Content

[0023] Example:

[0024] Reference Figure 1-5 A baler with a dust removal device comprises: a baler body 1, a picking roller 3 is installed in the baler body 1, a tool shell 2 is fixedly installed on the outer side of the baler body 1, a dust suction cavity tube 4 is fixedly installed on the inner wall of the tool shell 2, a plurality of dust suction nozzles 5 with openings facing downwards are evenly distributed on the dust suction cavity tube 4, one end of the dust suction cavity tube 4 is connected to a blowing device 6 through a connecting tube 1 61, and a dust suction device 8 is connected to the side of the dust suction cavity tube 4 away from the blowing device 6 through a connecting tube 2 7, the blowing device 6 and the dust suction device 8 are fixedly connected to both sides of the tool shell 2 respectively, and the output end of the dust suction device 8 faces downwards.

[0025] The input direction of the dust nozzle 5 is perpendicular to the inclined surface 21 of the bottom edge of the tool housing 2 .

[0026] A filter screen 51 is fixedly mounted on the input port of the dust suction nozzle 5 .

[0027] A rectangular shell 80 is provided on the dust collecting device 8, and the input end of the rectangular shell 80 is fixedly connected to the connecting pipe 27. A mounting plate is fixedly installed on the side of the rectangular shell 80 close to the connecting pipe 27, and a servo motor 82 is fixedly installed on the mounting plate. The power output end of the servo motor 82 is transmission-connected to the fan 81, and a filtering structure is fixedly installed on the output end of the rectangular shell 80 away from the connecting pipe 27. The filtering mechanism includes a cover plate 83 and a cylindrical filter element 84. The cover plate 83 and the cylindrical filter element 84 are an integrally formed structure. The cylindrical filter element 84 is located in the rectangular shell 80, and the cover plate 83 is fixedly connected to the opening of the rectangular shell 80. A vent hole 831 is preset in the middle of the cover plate 83 to communicate with the cylindrical filter element 84.

[0028] The servo motor 82 can drive the fan 81 to rotate in both counterclockwise and clockwise directions.

[0029] Fixing blocks 85 are installed and fixed at the four vertex positions in the rectangular housing 80 , and the cover plate 83 is threadedly connected and fixed to the threaded holes on the fixing blocks 85 via bolts 86 .

[0030] A one-way valve 9 is installed at the connection portion between the connecting pipe 1 61 and the dust suction chamber pipe 4;

[0031] like Figure 3 As shown, the one-way valve 9 installed at the connection between the connecting pipe 61 and the dust suction chamber tube 4 can allow the gas blown out from the blowing device 6 to enter the dust suction chamber tube 4 normally through the connecting pipe 61, and at the same time prevent the gas blown out from the dust suction device 8 from breaking the blockage of the filter 51 on the dust suction nozzle 5, thereby preventing the gas mixed with dust from being blown into the blowing device 6.

[0032] Working principle: When the utility model is in working state, the pick-up roller 3 in the baler body 1 starts to operate to bale crops such as grass and straw on the ground. During the baling process, a large amount of dust particles will be generated because the pick-up roller 3 picks up grass and straw and contacts with the ground soil. By starting the servo motor 82 in the blowing device 6 and the dust suction device 8, the dust generated by the running state of the pick-up roller 3 can be adsorbed. The adsorbed dust particles enter the dust suction cavity 4 through the dust suction nozzle 5. The filter 51 on the dust suction nozzle 5 can filter the large-sized grass mixed in the dust. Figure 3 As shown, the dust sucked into the dust suction chamber 4 flows to the right through the connecting pipe 2 7 and enters the dust suction device 8. Starting the blowing device 6 can promote the dust accumulated in the dust suction chamber 4 to enter the dust suction device 8 more quickly. Figure 4As shown, the servo motor 82 is started to drive the fan 81 to rotate and generate suction, so that the dust is sucked into the rectangular housing 80 through the connecting pipe 27 and filtered by the cylindrical filter element 84. The dust is collected on the outer surface of the cylindrical filter element 84 or in the closed area formed by the cylindrical filter element 84 and the rectangular housing 80. The purified gas can be discharged outward through the vent hole 831 in the middle of the cover plate 83. The design of the rectangular housing 80 opening downward, and the combination of the fixing block 85 and the bolt 86 to quickly install and disassemble the filter mechanism composed of the cover plate 83 and the cylindrical filter element 84 facilitates the operator to clean or replace the surface of the cylindrical filter element 84, thereby improving the filtering effect of the dust collection device 8;

[0033] When the filter 51 on the dust nozzle 5 is clogged during long-term working and affects the dust adsorption effect, the blowing device 6 can be turned off and the servo motor 82 can be started to drive the fan 81 to rotate in the opposite direction, and a blowing force is generated on the filter 51 through the connecting pipe 2 7, the dust suction chamber tube 4 and the dust suction nozzle 5 in turn. The blown gas can clear the clogged filter 51, reducing the cleaning burden of the operator on the filter 51, thereby improving the dust suction effect of the dust suction chamber tube 4 and effectively reducing the dust generated by the baling operation state of the baler body 1.
