Description

Technical Field

[0001] This utility model relates to the technical field of agricultural machinery, and in particular to an integrated machine for crushing and baling straw. Background Technology

[0002] In agricultural production, harvested straw is usually crushed and then packaged. This facilitates transportation and storage, reduces contact with air, and extends shelf life.

[0003] In existing technologies, a crushing device is typically connected to a filtering device, which in turn connects to a baling machine, following a process of crushing, filtering, and finally baling. However, this method has significant drawbacks: firstly, crushing before filtering results in the removal of finely crushed straw particles along with dust and other impurities, leading to resource waste. Secondly, multiple pieces of equipment need to be assembled on-site, making the process cumbersome, increasing operational complexity, and impacting production efficiency. Utility Model Content

The air inlet 506 is located at the bottom of the fan housing 501 and is positioned at the front end inside the screen body 301. The air outlet of the fan 5 is located above the impeller 503. When the blower 5 is working, the fourth shaft 502 drives the impeller 503 to rotate, which generates a negative pressure inside the blower housing 501. The negative pressure draws the material on the screen body 301 into the air inlet 506. Then, the material enters the air duct 6 through the air outlet by the negative pressure and the pushing action of the impeller 503 blades. After passing through the air duct 6, it enters the dust removal screen 7.

[0042] The cylinder body of the first hydraulic cylinder 902 is mounted on the frame 1, and the end of the cylinder rod of the first hydraulic cylinder 902 is connected to the first push plate 903. The first hydraulic cylinder 902 is used to drive the first push plate 903 to push and compress the material falling from the crushing box 8 forward. The cylinder body of the second hydraulic cylinder 905 is mounted on the frame 1, and the end of the cylinder rod of the second hydraulic cylinder 905 is connected to the second push plate 906.

[0045] Furthermore, in a preferred embodiment, a scale and multiple sensors are also included. The scale is installed at the bottom inside the baler housing 901. When the first hydraulic cylinder 902 is in the retracted state, the first push plate 903 and the baffle 904 are both located behind the feed inlet 909. At this time, the feed inlet 909 is in the open state, and the material from the crushing box 8 will fall onto the scale. When the weight reaches the preset weight, the signal from the pressure sensor triggers the first hydraulic cylinder 902 to work, causing the first hydraulic cylinder 902 to extend forward, driving the first push plate 903 and the baffle 904 to move forward. The material is gradually compressed by the first push plate 903. When the extension reaches the limit position, the first displacement sensor is triggered to send a signal to the second hydraulic cylinder 905. The second hydraulic cylinder 905 drives the second push plate 906 to move downward. The second push plate 906 compresses the material pushed by the first push plate 903 for the second time.

[0053] Working principle:

[0054] First, material is fed into hopper 201. After being conveyed by conveyor belt device 202 and agitated by stirring rod 207, the material falls from the first discharge port 204 onto vibrating dust collector screen 3. Through vibration screening, dust and other impurities in the material fall through the screen holes of screen body 301 onto waste conveyor belt assembly 4. Waste conveyor belt assembly 4 then conveys the dust and other impurities to extended waste conveyor belt assembly 21, which in turn conveys them to transport vehicles. Simultaneously, fan 5 draws material from the front end of screen body 301 into air inlet 506. Next, the material enters the dust collector screen 7 through air duct 6. Under the blowing action of the wind, dust and other fine impurities are discharged through the screen holes of the dust collector screen 7. The material after secondary filtration falls into crushing box 8. Then, multiple crushing blades 803 crush the material from the dust collector screen 7, and the crushed material falls into baler 9. The baler 9 compresses the material into a square shape and pushes it out from the second discharge port 910, where it is then wrapped and packaged by the wire wrapping and cutting system 26.

[0055] This invention comprises a feeding device 2, a vibrating dust collector 3, a waste conveyor belt assembly 4, a fan 5, a dust collector 7, a crushing box 8, and a baler 9. Material is conveyed to the vibrating dust collector 3 via the feeding device 2, where it undergoes preliminary screening. The screened-out dust and other impurities are conveyed and collected via the waste conveyor belt assembly 4. The pre-screened material is then driven by the fan 5 to the dust collector 7 for secondary screening, followed by crushing in the crushing box 8, and finally baled by the baler 9. Compared to the existing technology's pre-crushing and post-screening process, which easily results in the filtration of finely crushed straw along with dust and other impurities, this invention reduces material waste and lowers particulate matter emissions.

[0056] This utility model is used for straw crushing and baling. By integrating multiple functions such as feeding, vibration screening, collection of waste from primary screening, secondary screening, crushing and baling into one unit, it significantly improves work efficiency, reduces production costs, and thus effectively increases farmers' economic benefits.

[0057] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
