Description

Technical Field

[0001] This utility model relates to the field of tractor chassis technology, and in particular to a compact tractor chassis assembly. Background Technology

[0002] The chassis of a tractor is the device that transmits power to the drive wheels and working device, enabling the tractor to move and complete mobile or stationary operations. However, current agricultural tractors still have some shortcomings in use. For example, agricultural tractor chassis are usually equipped with a tow hook for trailer towing, one end of which is threaded. The tow hook needs to be installed through the thread each time it is used, and it also needs to be disassembled after use, making it cumbersome to use and inconvenient to store. Furthermore, the tow rope is prone to detaching from the hook when it becomes loose, making it difficult to secure the tow rope to the hook.

[0003] To address the aforementioned issues, existing patent (CN221417867U) discloses a novel agricultural tractor chassis assembly, including a chassis frame. A mounting block is fixedly connected to the side wall of the chassis frame. A groove is formed on the side wall of the mounting block, and a movable plate with an L-shaped structure is slidably connected inside the groove. A hook is threadedly connected to the side wall of the movable plate, and a limiting screw is threadedly connected through the side wall of the hook. Symmetrically symmetrical grooves are formed on the side wall of the movable plate, and a limiting block is slidably connected inside each groove. A second spring is fixedly connected to the side wall of each limiting block, and limiting grooves are symmetrically formed on the side wall of the groove. This invention, by incorporating a winding reel, pull rope, limiting ring, sliding rod, second spring, movable plate, and groove, allows the hook to retract into the groove after use for easy reuse. Furthermore, the movable plate, hook, and limiting screw create a closed structure for the hook, preventing the traction rope from detaching from the hook when it becomes loose.

[0004] However, in the aforementioned prior art, the tractor chassis is directly exposed to the outside. Since key components such as the engine, gearbox, and transmission system are directly mounted on the chassis, dirt, stones, and other debris can easily impact and corrode these key components. Summary of the Invention

[0005] The purpose of this utility model is to provide a compact tractor chassis assembly, which solves the technical problem in the prior art where the chassis of the tractor is directly exposed to the outside, and because key components such as the engine, gearbox and transmission system are directly set on the chassis, dirt, stones and other debris can easily cause impact and erosion to the key components.

[0006] To achieve the above objectives, this utility model employs a compact tractor chassis assembly, comprising a chassis body and a protection mechanism. The protection mechanism includes a drive shaft, a drive wheel, and a protection component. The drive shaft is rotatably connected to the chassis body and located below the chassis body. The drive wheel is fixedly connected to the drive shaft and located outside the drive shaft. The protection component includes a protective base plate, a protective bushing, a baffle, a suction element, and an auxiliary component. The protective base plate is detachably connected to the chassis body and located below the drive shaft. The protective bushing is fixedly connected to the protective base plate and located outside the protective base plate. The baffle is detachably connected to the chassis body and located on the side of the chassis body adjacent to the protective base plate. The suction element is fixedly connected to the baffle and located outside the baffle. The auxiliary component is slidably connected to the baffle and located below the baffle.

[0007] The adsorption component includes a telescopic spring and a protective plate. The telescopic spring is fixedly connected to the baffle and is located on the side of the baffle away from the chassis body. The protective plate is fixedly connected to the telescopic spring and is located on the outside of the telescopic spring.

[0008] The adsorption component further includes a rubber adsorption layer, which is fixedly connected to the protective plate and located on the side of the protective plate away from the telescopic spring.

[0009] The adsorption component further includes a fixed sleeve, a telescopic rod, and a buffer pad. The fixed sleeve is fixedly connected to the baffle and is located below the telescopic spring. The telescopic rod is slidably connected to the fixed sleeve and is located on the side of the protective plate away from the rubber adsorption layer. The buffer pad is fixedly connected to the fixed sleeve and is located outside the telescopic rod.

[0010] The auxiliary components include a mudguard, mounting bolts, and an extension plate. The mudguard is detachably connected to the protective plate and is located below the protective plate. The mounting bolts are bolted to the protective plate and are located below the mudguard, with the mounting bolts penetrating through the mudguard. The extension plate is fixedly connected to the mudguard and is located on the outside of the mudguard.

[0011] This utility model discloses a compact tractor chassis assembly. In practical use, a protective base plate is installed on the underside of the chassis body using bolts. A protective bushing encloses the drive shaft, and a baffle is installed on the outside of the chassis body. The protective base plate, together with the protective bushing, protects the chassis body and the drive shaft. The drive shaft drives the drive wheels, causing the chassis body to move. When the tractor experiences a collision, the suction component absorbs the impact force, thereby reducing the damage to the chassis body. This method effectively solves the problem.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] This utility model provides a compact tractor chassis assembly, including a chassis body 101 and a protection mechanism. The protection mechanism includes a drive shaft 102, a drive wheel 103, and a protection component. The protection component includes a protective base plate 104, a protective bushing 105, a baffle 106, an adsorption element, and auxiliary components. The adsorption element includes a telescopic spring 107, a protective plate 108, a rubber adsorption layer 109, a fixing sleeve 110, a telescopic rod 111, and a buffer pad 112. The auxiliary components include a mudguard 113, mounting bolts 114, and an extension plate 115. The aforementioned solution solves the problem that the tractor chassis is directly exposed to the outside, and because key components such as the engine, gearbox, and transmission system are directly mounted on the chassis, mud, stones, and other debris can easily impact and corrode these key components.

[0021] In this specific embodiment, the drive shaft 102 is rotatably connected to the chassis body 101 and located below the chassis body 101. The drive wheel 103 is fixedly connected to the drive shaft 102 and located outside the drive shaft 102. The protective assembly includes a protective base plate 104, a protective bushing 105, a baffle 106, an adsorption component, and auxiliary components. The protective base plate 104 is detachably connected to the chassis body 101 and located below the drive shaft 102. The protective bushing 105 is fixedly connected to the protective base plate 104 and located outside the protective base plate 104. The baffle 106 is detachably connected to the chassis body 101 and located on the side of the chassis body 101 adjacent to the protective base plate 104. The adsorption component is connected to the baffle 106. The auxiliary component is fixedly connected and located outside the baffle 106. The auxiliary component is slidably connected to the baffle 106 and located below the baffle 106. The protective base plate 104 is installed below the chassis body 101 using bolts. The protective bushing 105 wraps around the drive shaft 102. The baffle 106 is installed on the outside of the chassis body 101 by bolts. The protective base plate 104, together with the protective bushing 105, protects the chassis body 101 and the drive shaft 102. The drive shaft 102 drives the drive wheel 103 to move, causing the chassis body 101 to move. When the tractor is involved in a collision, the adsorption component adsorbs the impact force, thereby reducing the damage to the chassis body 101. This method can effectively solve the problem.

[0022] The telescopic spring 107 is fixedly connected to the baffle 106 and is located on the side of the baffle 106 away from the chassis body 101. The protective plate 108 is fixedly connected to the telescopic spring 107 and is located on the outside of the telescopic spring 107. When the protective plate 108 is impacted, the telescopic spring 107 is compressed, thereby reducing the impact force.

[0023] Secondly, the rubber adsorption layer 109 is fixedly connected to the protective plate 108 and is located on the side of the protective plate 108 away from the telescopic spring 107. The rubber adsorption layer 109 is disposed on the outside of the protective plate 108, and the rubber adsorption layer 109 initially adsorbs the impact force.

[0024] Meanwhile, the fixed sleeve 110 is fixedly connected to the baffle 106 and located below the telescopic spring 107. The telescopic rod 111 is slidably connected to the fixed sleeve 110 and located on the side of the protective plate 108 away from the rubber adsorption layer 109. The buffer pad 112 is fixedly connected to the fixed sleeve 110 and located outside the telescopic rod 111. One end of the telescopic rod 111 is fixedly connected to the protective plate 108. Thus, when the protective plate 108 compresses the telescopic spring 107 backward, the telescopic rod 111 slides inside the fixed sleeve 110. When the telescopic rod 111 slides completely to the fixed sleeve 110, the buffer pad 112 contacts the protective plate 108, thereby further improving the reduction of impact force. The telescopic rod 111, in conjunction with the fixed sleeve 110, supports the protective plate 108, enabling the protective plate 108 to move stably.

[0025] Additionally, the mudguard 113 is detachably connected to the protective plate 108 and is located below the protective plate 108. The mounting bolt 114 is bolted to the protective plate 108 and is located below the mudguard 113, with the mounting bolt 114 penetrating through the mudguard 113. The extension plate 115 is fixedly connected to the mudguard 113 and is located on the outside of the mudguard 113. The mudguard 113 is installed below the protective plate 108 by the mounting bolt 114. The mudguard 113 and the extension plate 115 prevent mud or impurities from flying into the telescopic spring 107 and the fixing sleeve 110. When the protective plate 108 moves, the mudguard 113 slides on the outside of the protective base plate 104.

[0026] Using a compact tractor chassis assembly according to this embodiment, by setting the drive shaft 102, the drive wheel 103, and the protective components, in specific use, the protective base plate 104 is bolted to the underside of the chassis body 101, the protective bushing 105 wraps around the drive shaft 102, and the baffle 106 is bolted to the outside of the chassis body 101. The protective base plate 104, in conjunction with the protective bushing 105, protects the chassis body 101 and the drive shaft 102. The drive shaft 102 drives the drive wheel 103, causing the chassis body 101 to move. When the tractor experiences a collision, the rubber adsorption layer 109 initially absorbs the impact force. The guard plate 108 compresses the telescopic spring 107 backward, thereby reducing the impact force. The telescopic rod 111 slides within the fixed sleeve 110. When the telescopic rod 111 slides completely into the fixed sleeve 110, the buffer pad 112 contacts the guard plate 108, thereby further enhancing the reduction of the impact force. The mudguard 113 is installed below the guard plate 108 by the mounting bolt 114. The mudguard 113 and the extension plate 115 prevent mud or impurities from flying into the telescopic spring 107 and the fixed sleeve 110, thereby effectively protecting the key components of the tractor chassis, effectively preventing mud, stones and other debris from impacting and corroding the key components, and effectively reducing the impact force damage to the chassis assembly.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
