Description

Technical Field

[0001] This utility model relates to the technical field of connection structure between the press assembly and the large gearbox, specifically a plug plate structure for connecting the press assembly to the large gearbox body. Background Technology

[0002] The connecting rod connecting the large gearbox and the press assembly is located at the top of the machine and is an independent connecting mechanism that adjusts the working depth of the rake. The large gearbox and press assembly are connected via the connecting rod mechanism (including the connecting rod and a straight plate with adjustment holes). The working height of the gearbox can be limited by the adjustment holes on the straight plate, thereby adjusting the working depth of the rake. (Since the rake under the large gearbox is rotating during operation, it cannot provide vertical support to the gearbox; in addition, the three-point suspension above only provides forward tension during operation; therefore, the press roller needs to be connected to the large gearbox via the connecting rod mechanism, working in conjunction with the three-point suspension to support the gearbox during operation, thus limiting the working depth of the rake). The entire connecting rod structure occupies a relatively large space. Utility Model Content

[0003] The purpose of this utility model is to provide a large gearbox plug plate structure for connecting the press assembly, so as to solve the problems of large volume and high production cost of existing connecting rod structures.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a large gearbox end plate structure for connecting a pressing assembly, comprising an end plate, a bracket, a bracket support, and a pin. The end plate and the bracket support are both fixedly connected to the large gearbox. The end plate and the bracket support have holes with the same layout. One end of the bracket is movably connected to the end plate via a pin, and the other end is fixedly connected to the pressing assembly.

[0005] Preferably, the bull leg is connected to the press assembly by bolts, and the bolts have at least two holes.

[0006] Preferably, the end cap plate has a window for connecting to the large gearbox body, and is fixedly connected by welding.

[0007] Preferably, the end plate has a connecting block on the side facing the bracket, and is welded to the bracket through the connecting block.

[0008] Preferably, the bottom and sides of the bracket are provided with connecting plates, which are welded to the end plate.

[0009] Preferably, the upper end of the bracket has a notch, and the notch is welded to the large gearbox body.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the original connecting rod structure spanning across the press assembly and the large gearbox has been eliminated, the structure is simpler, the overall volume is greatly reduced, the drive rake space is saved, and the production cost is reduced.

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example

[0018] Please see Figures 1 to 4 A plug plate structure for a large gearbox connecting a pressing assembly includes a plug plate 1, a bracket 2, a bracket support 3, and a pin 4. The plug plate 1 and the bracket support 3 are both fixedly connected to the large gearbox 5. The plug plate 1 and the bracket support 3 have holes 9 with the same layout. By selecting appropriate holes 9 and inserting pins 11 and cotter pins 12, the range of motion of the bracket 2 is limited, thereby limiting the working depth of the rake. One end of the bracket 2 is movably connected to the plug plate 1 through the pin 4, and the other end is fixedly connected to the pressing assembly 6.

[0019] As shown in the figure, one end of the bracket 2 has a shaft hole 21 for connecting pin 4, and the other end has three bolt holes 22. Bolts are inserted to fix the bracket 2 to the pressing assembly 6.

[0020] In a preferred embodiment of this invention, the end plate 1 is provided with a window 10 for connecting the large gearbox 5, and the end of the large gearbox 5 is inserted into the window 10 and fixedly connected by welding.

[0021] In a preferred embodiment of this invention, the end plate 1 is provided with a connecting block 7 on the side facing the bracket 3, and is welded to the upper part of the bracket 3 through the connecting block 7.

[0022] In a preferred embodiment of this invention, the bottom and sides of the bracket 3 are provided with connecting plates 8, which are welded to the end plate 1.

[0023] As a preferred embodiment of this example, the upper end of the bracket 3 has a notch 30, and the notch 30 is welded to the large gearbox 5.

[0024] In a preferred embodiment of this invention, the bracket 3 has an insertion hole 31 for inserting the connecting block 7, and a pin hole 32 for inserting the pin 4.

[0025] Since the rake blade under the large gearbox 5 is in a rotating state during operation, it cannot provide vertical support to the large gearbox. In addition, the three-point suspension above only provides forward pulling force during operation. Therefore, the pressure roller needs to be connected to the large gearbox 5 through the bracket 2 and the end plate 1 to support the large gearbox 5 in conjunction with the three-point suspension during operation, thereby limiting the working depth of the rake blade. The working depth of the rake blade is adjusted by adjusting the insertion position of the pin 4 into the hole 9.

[0026] The operation is as follows: After the drive harrow is attached to the tractor, lift the drive harrow and insert pin 4 into hole H. This position represents the shallowest harrowing depth (i.e., the highest position of the large gearbox relative to the drive harrow during operation). Start the tractor and move forward via the power take-off shaft (the tractor's power is output from the power take-off shaft, transmitted through the drive shaft to the drive harrow's transmission box, and then transmitted from the transmission box to the various gear shafts within the large gearbox. The gear shafts are connected to the cutter head and harrow blades via splines and rotate accordingly, at which point the drive harrow is in working condition). After traveling a certain distance, stop and check the working depth. If the working depth meets the requirements, continue working at that depth. If it does not meet the requirements, insert the pin into hole G and continue the above operation until the required working depth is reached. In other words, start by testing the harrowing depth from H to D. If H does not meet the requirements, insert pin G; if G does not meet the requirements, insert pin F; and continue trying E, D, C, etc., until the requirements are met. Generally speaking, the order of insertion depth from shallow to deep is HGFEDC.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
