DETAILED DESCRIPTION

[0024] The utility model will be described in further detail below in combination with the drawings.

[0025] Embodiment 1

[0026] Referring to Figures 1-3 , the baling press comprises a baling press main push head 1, a final pressure oil cylinder 2 and a material box 3, the baling press main push head 1 is connected with four final pressure oil cylinders 2, and the baling press main push head 1 moves in the door opening 3.1 of the material box 3 under the drive of the four final pressure oil cylinders 2 to compress the material (not shown) located between the material box 3 and the initial pressure push head 4.

[0027] The baling press main push head 1 comprises an end face 1.1, a top face 1.2, a bottom face 1.3, a front side face 1.4 and a rear side face 1.5, the end face 1.1 is a material compression face (i.e. a surface that contacts and compresses the material), the top face 1.2, the bottom face 1.3, the front side face 1.4 and the rear side face 1.5 are all adjacent to the material compression face, the top face 1.2 and the bottom face 1.3 are opposite in the vertical direction respectively, and the front side face 1.4 and the rear side face 1.5 are opposite in the front-rear direction respectively, wherein the front side face 1.4 is a surface of the baling press main push head 1 that faces away from the initial pressure push head 4, and the rear side face 1.5 is a surface of the baling press main push head 1 that faces towards the initial pressure push head 4; a part of the front side face 1.4 that is far away from the end face 1.1 is recessed inward to form a stepped face 10.

[0028] Preferably, the baling press main pusher 1 comprises a pusher body 11 and an end plate 12, the end face 1.1, the top face 1.2, the bottom face 1.3, the front side face 1.4 and the rear side face 1.5 are located on the pusher body 11, and the end plate 12 is fixed to one end of the pusher body 11 away from the end face 1.1, and the end plate 12 is used to connect with the cylinder rod 2.1 of the final pressing cylinder 2. Among them, Figure 1 The baling press shown in the middle of the figure only has one baling press main pusher 1 on one side of the material box 3, but those skilled in the art can understand that one baling press main pusher 1 can also be arranged on both sides of the material box 3 respectively, and each baling press main pusher 1 is driven by multiple final pressing cylinders 2.

[0029] The principle of reducing the wear of the main pusher and the material box door hole in the embodiment scheme is analyzed as follows.

[0030] As Figure 4 shown, the existing baling press main pusher 1 also has an end face 1.1, a top face 1.2, a bottom face 1.3, a front side face 1.4 and a rear side face 1.5, and the top face 1.2, the bottom face 1.3, the front side face 1.4 and the rear side face 1.5 are all perpendicular to the end face 1.1, and the front side face 1.4 is not provided with a recessed step face. In actual use, before the baling press main pusher 1 enters the inside of the material box 3, the primary pressing pusher 4 first compresses the material, and after the compression is completed, the baling press main pusher 1 enters the inside of the material box 3 under the drive of the final pressing cylinder 2 to further compress the material, and there is a certain gap between the baling press main pusher 1 and the primary pressing pusher 4. In the process of compressing the material, when the A point at the front of the baling press main pusher 1 is blocked by material or for other reasons, a large extrusion force F will be generated, which will make the baling press main pusher 1 have a tendency to deflect clockwise. Since the baling press main pusher 1 is closely attached to the door hole 3.1, the B point and the C point of the door hole 3.1 of the material box 3 will be subjected to counter forces F1 and F2 respectively, wherein the counter force of the B point is greater than that of the C point, and the counter force F1 of the B point is F×L AC / L BC , L AC , L BC respectively represent the distance between AC and the distance between BC. Therefore, the longer the compression distance (stroke) of the baling press main pusher 1, the longer L ACThe larger the size is, the greater the friction force borne by the point B of the door hole 3.1 of the material box 3 is, and the point B of the door hole 3.1 of the material box 3 is prone to wear and even structural damage. The reason why the single baling machine main push head 1 is prone to the tendency of clockwise deflection is that the single baling machine main push head 1 is connected with multiple final pressure oil cylinders 2, and the cylinder rod 2.1 of the single final pressure oil cylinder 2 is relatively slender. Compared with the case that the single baling machine main push head 1 is fixedly connected with a single thick final pressure oil cylinder 2, the slender cylinder rod 2.1 is more prone to elastic deformation, and the rigidity provided by the baling machine main push head 1 is insufficient to limit the movement track of the baling machine main push head 1.

[0031] In the scheme provided by the utility model, a part of the front side 1.4 away from the end surface 1.1 is inwardly recessed to form a stepped surface 10, and the stepped surface 10 is used to actively adapt to the clockwise deflection tendency of the baling machine main push head 1, so that excessive wear and damage to the point B (i.e. the side of the door hole close to the initial pressure push head) of the door hole 3.1 of the material box 3 are avoided.

[0032] In order to better coordinate the actions of the multiple final pressure oil cylinders 2, the cylinder rod 2.1 is movably connected with the baling machine main push head 1. In this way, the baling machine main push head 1 can swing (rotate) relative to the cylinder rod 2.1 to a certain extent, and in combination with the stepped surface 10 design of the baling machine main push head 1, the actions of the multiple final pressure oil cylinders 2 can be well coordinated, and the wear of the baling machine main push head 1 and the door hole 3.1 of the material box 3 can be reduced. The movable connection between the cylinder rod 2.1 and the baling machine main push head 1 can be realized at least in the following two ways, and of course, other forms of movable connection can also be adopted by those skilled in the art as long as the baling machine main push head 1 can swing relative to the cylinder rod 2.1.

[0033] As shown in FIG. 1, the movable connection between the cylinder rod 2.1 and the baling machine main push head 1 can be realized in the following two ways. Figure 5 As shown in FIG. 1, the movable connection between the cylinder rod 2.1 and the baling machine main push head 1 can be realized in the following two ways.

[0034] As shown in FIG. 1, the movable connection between the cylinder rod 2.1 and the baling machine main push head 1 can be realized in the following two ways. Figure 6 As shown in FIG. 1, the movable connection between the cylinder rod 2.1 and the baling machine main push head 1 can be realized in the following two ways.

[0035] Embodiment 2

[0036] As Figure 7 shown, on the basis of Embodiment 1, the part of bottom surface 1.3 away from end surface 1.1 is also concave to form step surface 10, and the principle of setting step surface 10 on front side surface 1.4 is the same, so that it can avoid excessive wear and damage to the upper side of the door hole of material box 3.

[0037] Embodiment 3

[0038] As Figures 8-9 shown, the difference from Embodiment 1 is that front side surface 1.4 is not provided with step surface 10, but is provided with inclined surface 16 (as Figure 8 shown), or the part of front side surface 1.4 away from end surface 1.1 is inclined surface 16 (as Figure 9 shown), and the angle between inclined surface 16 and end surface 1.1 is less than 90 degrees. The angle between inclined surface 16 and end surface 1.1 refers to the angle formed by the intersection of the extension of inclined surface 16 and end surface 1.1, and the angle is less than 90 degrees, which achieves the same or similar technical effect of concave step surface 10 in Embodiment 1.

[0039] Further preferably, bottom surface 1.3 is inclined surface, or the part of bottom surface 1.3 away from end surface 1.1 is inclined surface 16 (not shown), and the angle between inclined surface 16 and end surface 1.1 is less than 90 degrees.

[0040] The embodiments of the utility model are described above in combination with the drawings, and in the case of no conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other. The utility model is not limited to the above-mentioned specific embodiments, and the above-mentioned specific embodiments are only illustrative, but not limited, and the ordinary skilled in the art can make many forms under the inspiration of the utility model without departing from the purpose of the utility model and the scope protected by the claims, and these all belong to the protection scope of the utility model.
