Description

Technical Field

[0001] This utility model relates to the field of chipper technology, specifically a push rod device for a chipper. Background Technology

[0002] The wood chipper is one of the main machines in the raw material preparation section of wood chip production. It uses wood chips, bamboo chips, and veneer fragments as raw materials to plane them into wood chips of a certain thickness, which are then used as raw materials for manufacturing particleboard. Generally, the raw materials are shaving by friction between two rotating rollers.

[0003] Chinese patent CN216266613U discloses a push rod device for a disc slicer, which is a key component of the disc slicer and is suitable for slicing and extruding raw materials such as bamboo. The technical solution is as follows: The push rod device for the disc slicer includes a cylinder, a push rod shaft, and a pressure plate; one end of the push rod shaft is provided with a limiting sleeve, which is installed on the push rod shaft by a locking nut, and the limiting sleeve limits the movement direction of the push rod shaft; a limiting plate is provided in the middle of the push rod shaft, through which the push rod shaft passes, and the limiting plate limits the movement direction of the push rod shaft; the other end of the push rod shaft is provided with a linear slider bearing, through which the push rod shaft passes, and the linear slider bearing limits the movement direction of the push rod shaft.

[0004] In the above technical solution, multiple cylinders are used to drive multiple push rods to move, which makes the production cost of the device high. Furthermore, since adjacent cylinders are connected by a connecting plate, if one of the cylinders fails, the entire device will become unusable, thus reducing the device's practicality.

[0005] Based on this, the present invention proposes a push rod device for a chipper. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a push rod device for a chipper, which enables a single motor to drive multiple push rod shafts through a drive assembly, reducing production costs and improving the device's practicality.

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides an improved push rod device for a chipper. The technical solution of this utility model is as follows:

[0026] like Figures 1-5As shown, a push rod device for a chipper includes a base 1, on which a housing 2 is fixedly connected. The inner diameter of the base 1 is the same as that of the housing 2. Multiple feed inlets 3 are provided on the base 1, arranged in a circular array around the center of the base 1. Multiple fixed housings 4 are fixedly connected inside the base 1. A drive assembly 5 is provided inside the housing 2. The drive assembly 5 includes a fixed box 51, a motor 52, a first gear 53, a second gear 54, a nut 55, a first screw 56, a connecting box 57, and a push rod shaft 58. The fixed box 51 is fixedly connected inside the housing 2, the motor 52 is fixed inside the housing 2 by bolts, and the first gear 53 is fixed inside the housing 2 by bolts. Fixed on the output shaft of motor 52, gear 1 53 is rotatably connected to fixed box 51, multiple gear 2 54 are rotatably connected to fixed box 51, gear 2 54 are arranged in a circular array with the center of gear 1 53 as the center, gear 1 53 meshes with gear 2 54, multiple nuts 55 are fixedly connected to multiple gear 2 54 respectively, multiple screws 1 56 are threadedly connected to multiple nuts 55 respectively, multiple connecting boxes 57 are fixedly connected to multiple screws 1 56 respectively, multiple connecting boxes 57 are slidably connected to multiple fixed shells 4 respectively, multiple push rod shafts 58 are respectively set in multiple connecting boxes 57, and auxiliary components 6 are provided on the outer shell 2.

[0027] Furthermore, such as Figure 2 and Figure 3 As shown, the drive assembly 5 also includes a limiting ring 59 and a push plate 510. Multiple limiting rings 59 are fixedly connected to multiple fixed housings 4, and multiple push plates 510 are fixedly connected to multiple push rod shafts 58. The push plate 510 is located at the bottom of the push rod shaft 58.

[0028] Furthermore, such as Figures 1-3 As shown, the drive assembly 5 also includes through holes 511. Multiple through holes 511 are formed on the housing 2. The diameter of the through holes 511 is slightly larger than the diameter of the screw 56. The screw 56 is located directly below the through holes 511.

[0029] Furthermore, such as Figures 1-3 As shown, the auxiliary component 6 includes a rotating door 61 and a sliding ring 62. Multiple rotating doors 61 are hinged to the outer shell 2 and are arranged in a circular array with the center of the outer shell 2 as the center. The sliding ring 62 is slidably connected to the outer shell 2.

[0030] Furthermore, such as Figure 3 and Figure 5 As shown, the auxiliary component 6 also includes a rotating plate 63 and a screw 64. Multiple rotating plates 63 are respectively hinged to multiple connecting boxes 57. Two rotating plates 63 are provided on one connecting box 57. The two are symmetrical about the push rod shaft 58. Multiple screws 64 are respectively threaded to multiple rotating plates 63.

[0031] Furthermore, such as Figure 3 and Figure 5 As shown, the auxiliary component 6 also includes a mounting plate 65. Multiple mounting plates 65 are fixedly connected to multiple push rod shafts 58 respectively. Multiple mounting plates 65 are slidably connected to multiple connecting boxes 57 respectively. The mounting plate 65 has threaded holes. The mounting plate 65 is fixed to the rotating plate 63 by the screw 64 to realize the installation of the push rod shaft 58.

[0032] The specific working method is as follows: Material is placed into base 1 through feed inlet 3. The shaving machine is started to shave the material. Motor 52 is started, and its output shaft drives gear 1 53 to rotate. Since gear 1 53 meshes with gear 2 54, gear 2 54 rotates accordingly, driving nut 55 to rotate. Because nut 55 is threaded onto screw 1 56, screw 1 56 moves downwards with the rotation of nut 55, causing connecting box 57 and push rod shaft 58 to move downwards, and push plate 510 moves downwards accordingly. The push plate 510 pushes the material. When the push rod shaft 58 needs to be replaced, the sliding ring 62 is pushed upward so that the sliding ring 62 moves away from the rotating door 61. Then the rotating door 61 is opened by rotating it, and the screw 64 is rotated so that the screw 64 disengages from the rotating plate 63 and the mounting plate 65. After the screw 64 is removed from the rotating plate 63, the rotating plate 63 is opened by rotating it, and the mounting plate 65 is removed from the connecting box 57. The mounting plate 65 and the push rod shaft 58 can then be removed from the fixed housing 4 for replacement.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
