Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a self-propelled straw granulator with a debris removal mechanism. Background Art

[0002] With the popularization of mechanized agricultural production, most agricultural planting has been mechanized. With the improvement of environmental protection awareness, the burning of crop straw after planting has been banned and replaced by recycling. The crop straw after harvest can be used as fuel, fertilizer or animal feed, and has a high utilization value.

[0003] In the prior art, there are various agricultural machines such as straw pickers, straw balers, and straw pelletizers. However, when recycling straw, on the one hand, the transportation cost of the straw is high, and on the other hand, due to the large amount of dust in the straw, the straw picking device will also bring part of the dust into the straw due to contact with the ground when picking up the straw, thus affecting the effective utilization of the straw. In particular, when used as animal feed, the dust will seriously affect the quality of the feed, and a special dust cleaning step is required, resulting in increased recycling costs.

[0004] At present, there is an existing self-propelled biomass pellet picking machine (such as patent number: CN209997593U), which discloses a self-propelled biomass pellet picking machine, including a frame, wheels and a carriage, a straw picking and crushing kneading and cutting device is installed at the front end of the frame, a kneading and cutting device and a throwing device are arranged above the straw picking device, and a soil filtering device penetrating into the interior is arranged at the upper end of the carriage; the soil filtering device is a circular cylindrical structure, and a plurality of vertically arranged strip holes are opened on its side wall to accommodate dust passing through and block the straw; the straw picking device picks up the straw on the ground and transports it to the kneading and cutting device, and the kneading and cutting device kneads and crushes the straw and transports it to the soil filtering device through the throwing device. The utility model can effectively reduce the amount of dust in the straw, improve the quality of the straw, and does not require secondary treatment, thereby reducing the recycling cost.

[0005] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0006] 1. The existing device only filters dust through the soil filtering device, so the dust is filtered through only one step of the soil filtering device. Only one filtering process cannot guarantee that the dust is completely filtered, and the soil filtering device knocks the dust off through the collision of the inner wall with the straw to remove the dust. It is very difficult to completely shake off the dust through the collision. Therefore, the existing device has the problem of single and imperfect dust removal effect.

[0007] 2. The existing device mainly removes dust in terms of impurities, but its removal function for some stone-like impurities is not perfect, so the existing device has a problem of low impurity removal coverage. Utility Model Content

The two air inlets of the first fan 4 are located at the end of the first fan 4 away from the crawler automatic engineering vehicle 1, and the two air outlets of the first fan 4 pass through the outer wall of the crawler automatic engineering vehicle 1 toward the two cutting devices 7.

[0036] The feed port 5 is fixedly connected to the top surface of the crawler automatic engineering vehicle 1, and a second fan 501 is fixedly installed at one end of the feed port 5. The second fan 501 is provided with two air inlets and two air outlets. The two air inlets of the second fan 501 are located at the end of the second fan 501 away from the feed port 5, and the two air outlets of the second fan 501 are located at the end of the second fan 501 close to the feed port 5, and both air outlets penetrate the outer wall of the feed port 5 toward the inner side of the feed port 5. A dust exhaust groove 502 is provided on the side of the feed port 5 away from the second fan 501, and the feed port 5 is funnel-shaped as a whole.

[0037] The two second motors 701 are installed directly below the feed port 5, and the two second motors 701 are fixedly connected to the inner bottom surface of the crawler-type automatic engineering vehicle 1 on the side close to the first fan 4. A transmission shaft 702 is fixedly installed on the end of the second motor 701 away from the crawler-type automatic engineering vehicle 1, and a plurality of cutting blades 703 are fixedly connected to the transmission shaft 702.

[0038] Three mounting grooves 103 are fixedly opened at one end of the crawler-type automatic engineering vehicle 1 away from the first fan 4 , and the first motor 604 is fixedly installed in each of the three mounting grooves 103 .

[0039] There are three fixed frames 601 in total, and the three fixed frames 601 are all fixedly connected to the inner wall of the crawler automatic engineering vehicle 1. The three fixed frames 601 are connected to three screening tubes 602 for rotation together. One end of the screening tube 602 close to the first motor 604 is fixedly connected to an end plate 603, and one end of the end plate 603 close to the first motor 604 is fixedly connected to the driving shaft of the first motor 604. A section of the screening tube 602 close to the end plate 603 is provided with four discharge ports 605, and a section of the screening tube 602 away from the first motor 604 is provided with a plurality of screening holes 606.

[0040] The second impurity removal device 6 is arranged obliquely as a whole, wherein the end close to the first motor 604 is lower, and the end close to the cutting device 7 is higher.

[0041] The second motor 701 is started to drive the transmission shaft 702, and the transmission shaft 702 drives the cutting blade 703 to crush the straw, and the first fan 4 is started to blow it to the three screening tubes 602, and the first motor 604 is started to drive the end plate 603, and the end plate 603 drives the screening tube 602 to rotate in the fixed frame 601, and the straw fragments are continuously turned over as the screening tube 602 rotates. Impurities in the straw fragments, such as dust and stones, fall into the inner bottom surface of the crawler automatic engineering vehicle 1 through the sieve holes 606 during the continuous turning process, and are finally discharged through the impurity discharge trough 101. Because the second impurity removal device 6 is tilted as a whole, under the action of gravity, the straw will eventually fall into the discharge trough 102 through the discharge port 605, and finally fall into the connecting square tube 2 to be transmitted to the granulator body for subsequent processing, thereby solving the technical problems that the existing device has a single and imperfect dust removal effect and a low impurity removal coverage rate.

[0042] Working principle:

[0043] In the first step, the straw is poured in from the feed port 5. During the pouring process, the second fan 501 is started. The second fan 501 blows air to the straw through its air outlet, and the impurities in the straw are blown to the dust exhaust groove 502, and finally blown out through the dust exhaust groove 502. Since the straw body is large, it will be blocked by the dust exhaust groove 502, and then fall into the cutting device 7 under the action of gravity.

[0044] The second step is to start the second motor 701 to drive the transmission shaft 702, and the transmission shaft 702 drives the cutting blade 703 to crush the straw, start the first fan 4 to blow it to the three screening tubes 602, start the first motor 604 to drive the end plate 603, and the end plate 603 drives the screening tube 602 to rotate in the fixed frame 601, and the straw fragments are continuously turned over as the screening tube 602 rotates. Impurities in the straw fragments, such as dust and stones, fall into the inner bottom surface of the crawler automatic engineering vehicle 1 through the sieve holes 606 during the continuous turning process, and are finally discharged through the impurity discharge trough 101. Because the second impurity removal device 6 is tilted as a whole, the straw will eventually fall into the discharge trough 102 through the discharge port 605 under the action of gravity, and finally fall into the connecting square tube 2 to be transmitted to the granulator body for subsequent processing.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
