[0002] The chassis of a tractor is a power transmission device. Its function is to transmit the power of the engine to the drive wheels so that the tractor can move. In the existing technology, the engine is generally mounted on the chassis by shims. The shims are located between the engine and the bracket and play a supporting role. Moreover, the shims are mostly cast in one piece.

[0003] Shims are typically fixed to the top of the chassis with bolts, and the engine is fixed to the top of the shim with bolts. In order to accommodate the installation and fixing of engines of different specifications, the holes on the shims for connecting the engine are mostly elongated. During installation, in order to prevent the bolts from turning freely, the operator needs to use two wrenches, one for fixing the bolts and the other for turning the nuts, which is time-consuming and laborious.

[0004] Therefore, in order to solve the above problems, a high-strength chassis support casting for high-horsepower tractors is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength chassis bracket casting for high-horsepower tractors, in order to solve the problem mentioned in the background art that in order to be suitable for the installation and fixing of engines of different specifications, the holes on the shims for connecting the engine are mostly elongated. During installation, in order to avoid the bolts from turning freely, the operator needs to use two wrenches, one for fixing the bolts and the other for rotating the nuts, which is time-consuming and laborious.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength chassis support casting for a high-horsepower tractor, comprising: a chassis body, wherein an mounting groove is provided on the top surface of the chassis body, and an engine is mounted on the top surface of the chassis body; A connecting structure is installed on the chassis body. The connecting structure includes a shim, which is movably installed on the top surface of the chassis body. The front ends of the shim are connected to the first bolts by threads. The front end of the chassis body is inserted with a second bolt. The top ends of the shim have through grooves. The bottom ends of the shim have limit grooves. Rubber strips are adhered to the inner walls of the limit grooves. A third bolt is movably installed inside the limit grooves. The outer side of the middle part of the third bolt is connected to a nut by threads. The outer side of the upper end of the third bolt is connected to a cap by threads.

[0007] Preferably, the shim is horizontally positioned on the top surface of the chassis body, with both ends of the shim located on the upper side of the mounting groove.

[0008] Preferably, the rear end of the second bolt passes through the pad and is threaded to the front of the middle part of the pad.

[0009] Preferably, the through groove communicates with the inside of the limiting groove, and the engine covers the upper side of the through groove.

[0010] Preferably, the middle part of the third bolt passes through the pad through the through groove, the upper end of the third bolt passes through the engine, the rubber strip is clamped on both sides of the third bolt, and the bottom side wall of the third bolt is attached to the inner wall of the limiting groove.

[0011] Preferably, the cap is positioned on the outside of the nut.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By opening a limiting groove on the bottom surface of the shim, the angle of the third bolt can be limited, preventing the third bolt from rotating when tightening the nut and causing it to spin freely. In addition, a rubber strip is provided on the inner wall of the limiting groove, which can be clamped on both sides of the third bolt to position the third bolt inside the groove, avoiding the need for hand-holding and improving the convenience of connecting the engine and the shim.

[0013] This utility model, through a connecting structure, places a shim on the top surface of the chassis body. A second bolt penetrates the front of the chassis body and is rotated so that its rear end screws into the center of the front of the shim, thus fixing the shim at an angle on the top surface of the chassis body. At this point, both ends of the shim are located above two sets of mounting slots. A first bolt is then inserted upwards through the mounting slot and rotated so that its upper end screws into the two ends of the shim, thus fixing the shim to the top surface of the chassis body. Moving the engine to the top surface of the shim allows it to cover the upper side of the through slot. A third bolt is then inserted upwards through the through slot and the engine, with its bottom end positioned... Inside the limiting groove, the rubber strip abuts against the bottom sidewall of the third bolt, limiting the position of the third bolt inside the groove to prevent it from falling down. The bottom sidewall of the third bolt can also fit against the inner wall of the limiting groove, limiting the angle of the third bolt inside the groove. At this time, the operator can free up both hands to screw the nut onto the top of the third bolt without manually supporting and fixing it, making the installation of the engine on the shim more convenient. Finally, the cap is screwed onto the top of the third bolt. The cap can be fitted over the outside of the nut to protect it from corrosion and ensure the ease of disassembly and assembly of the device. Attached Figure Description

The front ends of the shim 21 are connected to the first bolt 22 by threads. The front end of the chassis body 1 is inserted with a second bolt 23. The top ends of the shim 21 have through grooves 24, and the bottom ends of the shim 21 have limit grooves 25. Rubber strips 26 are adhered to the inner wall of the limit grooves 25. A third bolt 27 is movably installed on the inner side of the limit grooves 25. The outer side of the middle of the third bolt 27 is connected by threads. The nut 28 is movably connected, and the upper outer side of the third bolt 27 is movably connected to the cap 29 by thread. By opening a limiting groove 25 on the bottom surface of the pad 21, the angle of the third bolt 27 can be limited to prevent the third bolt 27 from rotating when the nut 28 is tightened, thus preventing it from spinning freely. In addition, a rubber strip 26 is provided on the inner wall of the limiting groove 25, which can be clamped on both sides of the third bolt 27 to position the third bolt 27 inside the through groove 24, eliminating the need for hand-holding and improving the convenience of the connection between the engine 12 and the pad 21.

[0019] Furthermore, the shim 21 is horizontally arranged on the top surface of the chassis body 1, with both ends of the shim 21 located on the upper side of the mounting groove 11. The first bolt 22 in the mounting groove 11 can fix the shim 21 to the top surface of the chassis body 1.

[0020] Furthermore, the rear end of the second bolt 23 penetrates the pad 21 and is threadedly connected to the front of the middle part of the pad 21. The second bolt 23 can limit the angle of the pad 21 on the chassis body 1.

[0021] Furthermore, the through groove 24 is connected to the inside of the limiting groove 25, the engine 12 covers the upper side of the through groove 24, and the third bolt 27 in the limiting groove 25 can be exposed on the top surface of the pad 21 through the through groove 24.

[0022] Furthermore, the middle part of the third bolt 27 passes through the shim 21 via the through groove 24, the upper end of the third bolt 27 passes through the engine 12, the rubber strip 26 is clamped on both sides of the third bolt 27, and the bottom side wall of the third bolt 27 is attached to the inner wall of the limiting groove 25.
