Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural baling equipment, in particular to a spiral variable bin structure and a baler. Background Art
[0002] The baler is used for baling agricultural straw bales. The basic principle of straw bale forming is to arrange a number of forming rollers in a compression chamber. The operation of the forming rollers compresses the straw entering the compression chamber. Since there are multiple forming rollers evenly distributed in a circular shape in the forming rollers, when the straw continuously enters the compression chamber, the straw is pressed into a cylindrical shape with the help of the operation and extrusion of the forming rollers. When the pressure sensor measures that the pressure reaches the set threshold, the compression is stopped and the straw bale is released by opening the rear hatch. However, it is difficult to increase the density of the straw bale with the forming rollers arranged in a circular shape.
[0003] In the prior art, in order to increase the density of the straw bale, a structural form is adopted in which each forming roller can move toward the center of the circle on which the forming rollers are arranged. A plurality of forming rollers are driven synchronously toward the center position by a hydraulic cylinder to increase the density of the straw bale or change the diameter of the straw bale. However, this structural form increases the drive loss because the forming rollers need to move, resulting in higher costs and greater difficulty in maintenance. Utility Model Content

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.
[0036] like Figure 1 and Figure 2 As shown, the utility model discloses a spiral variable chamber structure, including a grass pressing roller 1 and a driving assembly 2, wherein: the grass pressing roller 1 is rotatably connected to the compression chamber, and a plurality of grass pressing rollers are arranged in the form of a spiral line structure, and the grass pressing rollers 1 are arranged with a gradually decreasing distance from the line connecting the center of the spiral line from the direction close to the grass inlet to the direction away from the grass inlet; specifically, as shown in FIG. Figure 2 As shown in the figure, the inner thick solid line is the shape of the grass bale, and the outer thick solid line is the spiral line of the center point of the grass pressing roller 1. Through the above arrangement, the grass pressing roller 1 is arranged in a non-circular shape, but the diameter structure is changed, so that the grass bale can be squeezed by the grass pressing roller 1 at any time when it rotates in the compression chamber, thereby ensuring the density of the grass bale. The drive assembly 2 is connected to the grass pressing roller 1, and is used to drive multiple grass pressing rollers 1 to rotate in the same direction. It should be pointed out here that in the embodiment of the utility model, the drive assembly 2 has a variety of structural forms, for example, it can be Figure 1As shown in the figure, the grass pressing roller 1 is driven to rotate by a chain installed on the gear of the grass pressing roller 1, or a plurality of motors can be used to drive the grass pressing roller 1 in a gear meshing manner; in the above method, since the position of each grass pressing roller 1 does not need to be changed, the cost and maintenance difficulty are reduced compared with the prior art.
[0037] In the above embodiment, the grass pressing rollers 1 are arranged in a spiral line, so that the distance between each grass pressing roller 1 and the center of the spiral line is gradually reduced, so that each grass pressing roller 1 will squeeze the grass after entering the compression chamber. Compared with the grass pressing rollers 1 arranged in a circular shape in the prior art, the pressure on the grass is more uniform, thereby further improving the density of the straw bale.
[0038] Alternatively, if Figure 2 As shown in , the grass pressing roller 1 is arranged in an Archimedean spiral or an equiangular spiral. Among the existing two-dimensional spirals, the Archimedean spiral and the equiangular spiral expand more evenly. The equiangular spiral is widely used, and the shaping and growth of many plants also adopt the form of equiangular spirals. In some embodiments of the utility model, an equiangular spiral is used. Its equation is Parameter a determines the magnification of the spiral. For example, the diameter of the existing baler bale is generally 1.2 meters. When a is 78, the distance between the point on the curve and the center of the spiral is taken as the radius to form a maximum circle with a diameter of 1450.8mm and a minimum circle with a diameter of 1406.5mm. The maximum circle diameter enclosed by this section of the spiral is 1420mm. After deducting the roller diameter of 222mm, the diameter of the working round bale is between 1200-1250mm, which can meet the existing requirement of 1.2 for bales. Similarly, changing the value of a and intercepting different angles of θ can obtain a spiral that meets the requirements.
[0039] Alternatively, if Figure 3 As shown in the figure, the grass pressing roller 1 comprises an axis head 11, a connecting shaft 12 fixedly connected to the axis head 11 coaxially, an axis disc 13 fixedly connected to the other end of the connecting shaft 12, a roller 14 fixedly connected to the axis head 11 and the axis disc 13, and a plurality of webs 15 fixedly connected between the connecting shaft 12 and the roller 14. Through the structural form of the connecting shaft 12 and the plurality of webs 15, the weight of the grass pressing roller 1 can be reduced on the one hand, and the structural strength of the grass pressing roller 1 can be improved on the other hand.
[0040] Optionally, in order to further reduce weight and improve structural strength, in the present utility model, as Figure 3 As shown in , the connecting shaft 12 is a hollow shaft, and the shaft head 11, the connecting shaft 12, the shaft disc 13, the roller 14 and the web 15 are all connected by plug welding. Regarding the welding of the web 15, it can be realized by opening holes corresponding to the web on the roller 14.
[0041] Alternatively, if Figure 4 and Figure 5 As shown in the figure, in order to further increase the friction between the roller 14 and the straw bale, the surface of the roller 14 has a convex structure. Specifically, the convex structure is a spiral structure (not shown in the figure) symmetrically arranged from the center of the roller 14 to both sides of the axial direction. By setting the symmetrical spiral convex structure, while increasing the friction, the straw in the compression chamber can also be evenly spread to both ends to better increase the density of the straw bale. Or as Figure 6 As shown in , the protruding structure is a strip-shaped structure extending axially and protruding radially. The arrangement of the strip-shaped structure can further improve the structural strength of the roller 14 while increasing the friction with the grass.
[0042] Alternatively, if Figures 7 to 9 As shown in , in order to reduce the difficulty of installing the forming roller, both ends of the roller 14 have a retaining ring 16 and a nylon disk 161 installed on the outside of the retaining ring 16. The nylon disk 161 has an external thread. The retaining ring 16 is respectively sleeved on the shaft disk 13 and the shaft head 11. Both ends of the roller 14 have internal threads that are screwed to the external threads on the nylon disk 161. Through such an arrangement, the axial clearance at both ends of the roller 14 is reduced, and replacement is convenient. In addition, the retaining ring 16 has an internal threaded hole, which is connected to the retaining ring 16 on the side of the shaft disk 13 by bolts. Through such an arrangement, when installing specifically, as shown in FIG. Figure 8 As shown in , the compression chamber side plate is connected to the retaining ring 16 by bolts. When the bolts are tightened, the retaining ring 16 will drive the nylon disk 161 to contact the compression chamber side wall, thereby reducing the gap between the compression chamber side wall and the roller 14; similarly, in the embodiment of the utility model, as Fig. 9 As shown in , the shaft head 11 side is also connected in sequence with a bearing seat 17, a first nut 171, a sprocket 18 and a second nut 181. When the connection is performed specifically, the bearing seat 17 has a bearing inside, and by tightening the first nut 171, the same principle can reduce the gap between the compression chamber side plate and the shaft head 11 side, and finally the sprocket 18 is fixed to the shaft head 11 through the second nut 181; through the above-mentioned settings, the difficulty of installation can be reduced, and the gap can be reduced to reduce the occurrence of grass entanglement at both ends of the roller 14.
[0043] In an embodiment of the utility model, a baler is also provided, comprising any of the above-mentioned spiral variable bin structures.
[0044] Application scenario of an exemplary embodiment:
[0045] like Figures 1 to 9As shown, when installing, first install the retaining ring 16 and the nylon disk 161 on both sides of the shaft head 11 and the shaft disc 13, then insert the shaft head 11 side into the bearing seat 17, then tighten the shaft disc 13 side with bolts, and then install the shaft head 11 side into the bearing chamber, and tighten it with the first nut 171 to reduce the gap between the two sides of the roller 14 and the compression chamber, and finally install the sprocket 18 and the second nut 181; through the above arrangement, the cost is reduced, the gap is reduced, and the convenience of installation is improved. When baling, the grass enters the compression chamber from the entrance, and contacts and squeezes the grass pressing roller 1 on the spiral line in turn under the rotation of the grass pressing roller 1, and finally fills the space in the entire grass pressing roller 1. When the pressure reaches the set threshold, the hatch opens, the grass bale falls from the compression chamber, and then the baling operation of the next grass bale is carried out.
