Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to an annular attached plate combined grass feeding roller. Background Art

[0002] The baler can compress and shape the remaining straw and forage grass in rural areas, such as corn stalks, rice straw, cereal straw, peanut straw and sheep grass, into bales, which are mainly used as feed for ruminants such as cattle and sheep, and can be used as reserve feed in pastoral areas, while solving the storage and transportation problems of forage grass. When the baler is working, the straw is forced into the compression chamber through the rotation of the picking roller, the grass pressing roller and the forced feeding roller. After reaching a certain density, the net winding mechanism starts to work, and the net rope enters the compression chamber to wrap the compressed straw. After the net rope reaches the set number of turns, the cutter cuts the net rope, and the rear box opens to release the baled straw.

This application solves the problem that the existing round balers are typical machines for forage harvesting and silage operations. At present, they are widely used in China, but there is a lack of round hay balers for thicker crop straw. However, the grass roller of the hay baler in this application does not have a structure to increase the friction between the straw and the grass roller. In practice, the insufficient friction between the grass feeding roller of the hay baler and the straw will cause the straw to fail to be smoothly fed into the baling mechanism, affecting the baling efficiency and the quality of the hay bales.

[0014] Beneficial Effects

[0015] The utility model provides a ring-shaped attached plate combined grass feeding roller. Compared with the prior art, it has the following beneficial effects:

[0016] 1. In the utility model, the friction between the straw feeding roller and the straw is successfully enhanced by the annular attached plate body and the convex block, which not only greatly improves the feeding speed of the straw when baling the straw, but also significantly reduces the risk of clogging of the feeding port. The straw passes through the feeding port smoothly, so that the speed of the baler in the whole operation process is greatly improved, thereby improving the production efficiency. More importantly, this design optimizes the performance of the baler, making the baler more efficient and stable when processing crops such as straw, greatly reducing the labor intensity of farmers and improving the automation level of agricultural production;

[0017] 2. In the utility model, by providing a lifting structure and an adjusting structure, when it is necessary to adjust the height of the grass feeding roller so as to bundle straw of different thicknesses, the adjusting handle is turned to drive the threaded rod to rotate, so that the threaded rod slides downward or upward inside the outer frame. When the threaded rod slides downward, the lifting seat is pushed downward to make the middle grass feeding roller slide downward. At this time, the tension spring is in a stretched state, and thinner straw is bundled. When the threaded rod slides upward, the lifting seat that loses the downward squeezing force will be affected by the restoring elastic force of the tension spring, and the lifting seat slides upward, driving the middle grass feeding roller to slide upward, and thicker straw is bundled. The functionality of the baler is increased, and the adjustment process of the position of the grass feeding roller is greatly facilitated, making the use of the baler more convenient and reliable.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4 The utility model provides two technical solutions, which specifically include the following embodiments:

[0026] Embodiment 1:

[0027] A grass feeding roller of annular attached plate combination type comprises a grass feeding roller body 1, a convex block 3 is arranged on the side surface of the grass feeding roller body 1, a plurality of convex blocks 3 are arranged, a ring-shaped attached plate body 2 is welded to the side surface of the grass feeding roller body 1, outer frames 4 are arranged at both ends of the grass feeding roller body 1, the outer frame 4 is installed at the front end of a baler, a lifting structure 5 is arranged on the inner surface of the outer frame 4, the lifting structure 5 comprises a lifting seat 505 and a lifting block 502, a lifting groove 501 is opened on the inner surface of the outer frame 4, a lifting rod 503 is fixedly connected to the inside of the lifting groove 501, a lifting block 502 is slidably connected to the surface of the lifting rod 503, both ends of the grass feeding roller body 1 are rotatably connected to the inside of the lifting seat 505, the lifting seat 505 and the lifting block 502 are fixedly connected to each other, and the lifting block 502 and the lifting groove 501 are arranged on the inner surface of the outer frame 4. A tension spring 504 is arranged between the inner top ends, and the tension spring 504 is arranged on the surface of the lifting rod 503. When the lifting block 502 descends in the lifting groove 501, the tension spring 504 is in a stretched state, and the lifting seat 505 is also in a descending state, driving the middle grass feeding roller body 1 to descend, so as to achieve the purpose of baling thinner rice straw. Twelve annular attached plate bodies 2 are arranged, and the spacing between the twelve annular attached plate bodies 2 is 125mm. The twelve annular attached plate bodies 2 are used to increase the friction between the grass feeding roller body 1 and the rice straw, thereby greatly improving the feeding speed of the rice straw and significantly reducing the risk of clogging the feeding port. The rice straw passes through the feeding port smoothly, so that the speed of the baler in the whole operation process is greatly improved, thereby improving the production efficiency.

[0028] When working, first, an outer frame 4 is installed at the front end of the baler. Inside the lifting seat 505, the grass feeding roller body 1 is connected by rotation, so that the grass feeding roller body 1 can rise and fall under the drive of the lifting seat 505. The function of the annular attached plate body 2 set on the side surface of the grass feeding roller body 1 is to increase the friction between the grass feeding roller body 1 and the straw, thereby increasing the feeding speed of the straw and reducing the risk of clogging the feeding port. When the baler starts working, the lifting seat 505 and the lifting block 502 interact with each other, so that the grass feeding roller body 1 and the annular attached plate body 2 descend together. When the lifting block 502 descends inside the lifting slot 501, the tension spring 504 is stretched, and the lifting seat 505 is also in a descending state, driving the grass feeding roller body 1 in the middle to descend. During this process, the straw is smoothly fed into the grass feeding roller body 1. Due to the presence of the annular attached plate body 2, the straw can generate greater friction with the annular attached plate body 2 when passing through the grass feeding roller body 1, which enables the straw to pass through the feeding port more smoothly, thereby increasing the speed of the baler during the entire operation process, thereby greatly improving the production efficiency. In general, this annular attached plate combined grass feeding roller increases the friction between the grass feeding roller body 1 and the straw through the setting of the annular attached plate body 2, effectively increases the feeding speed of the straw, reduces the risk of clogging the feeding port, and greatly increases the speed of the baler during the entire operation process, thereby improving production efficiency.

When the adjustment handle 701 rotates to drive the threaded rod 702 to rise, the lifting seat 505 that loses the downward pressure will slide upward due to the elastic force of the tension spring 504 to reset, thereby driving the middle grass feeding roller body 1 to slide upward, so as to achieve the purpose of baling thicker straw. The outer surface of the lifting seat 505 is provided with a driving structure 6. 6 includes a driving motor 601 and a motor seat 602, the motor seat 602 and the lifting block 502 are fixedly connected to each other, the driving motor 601 is installed at the upper end of the motor seat 602, the output end of the driving motor 601 is connected to the driving shaft, one end of the grass feeding roller body 1 is provided with a driving groove 603, the inner surface of the driving groove 603 is provided with a clamping groove 604, the driving shaft is connected to the inside of the driving groove 603 through the clamping groove 604, the driving motor 601 is installed on the motor seat 602, the motor seat 602 rises and falls with the lifting of the lifting block 502, and the driving motor 601 drives the driving shaft to rotate, thereby driving the middle The grass feeding roller body 1 rotates to achieve the purpose of baling the straw. A positioning structure 8 is installed at one end of the upper surface of the outer frame 4. The positioning structure 8 includes a fixing rod 801 and a positioning pin 804. The fixing rod 801 is fixedly connected to a corner of the upper surface of the outer frame 4. The inner upper end of the fixing rod 801 is slidably connected to a telescopic rod 802.

This process is conducive to baling thicker straw. At the same time, after the driving motor 601 is started, it can drive the grass feeding roller body 1 to rotate, further realizing the baling of the straw. After the adjustment is completed, the operator can calibrate through the scale lines 9 on the outer surface of the outer frame 4 to ensure that the two ends of the grass feeding roller are at the same level to ensure the smooth progress of the baling operation. In summary, during the operation of the baler, the adjustment structure 7, the driving structure 6 and the positioning structure 8 cooperate with each other to achieve precise control of the position, height and rotation of the grass feeding roller body 1, thereby improving the efficiency and quality of the straw baling operation.
