Description

Technical Field

[0001] The present application belongs to the field of agricultural machinery, and specifically relates to a tractor. Background Art

[0002] In recent years, as the core power equipment of agricultural mechanization, the functionality and adaptability of the traction device of the tractor directly affect the working efficiency and scope of use. At present, the tractor industry's escape design mainly focuses on the optimization of the four-wheel drive system. However, this type of technical solution has inherent limitations. When the vehicle is stuck in extreme working conditions such as deep mud and sand, it is difficult to achieve effective escape by relying solely on the four-wheel drive system.

[0003] A few tractors use a fixed connection structure to fix the traction device to the rear of the vehicle body. Although this can help to get out of trouble to a certain extent, this type of design has significant defects. First, the fixed connection method causes the traction device to occupy the rear interface of the vehicle for a long time, severely limiting the functional expandability of the tractor to connect other agricultural machinery and directly affecting the vehicle's multi-scenario applicability efficiency; secondly, the integrated structure makes it difficult to disassemble the traction device during maintenance and replacement, significantly increasing the maintenance time cost and operation complexity; more importantly, the existing traction device lacks an auxiliary parking device. When the vehicle is on a slope or soft ground, it is difficult to achieve reliable parking and fixation by relying solely on the traction device, and there is a risk of secondary slipping.

[0068] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present application, and are not used to limit the present application.

[0069] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0070] Currently, in the tractor industry, the design for getting out of trouble focuses on the optimization of four-wheel drive. There are few vehicles that get out of trouble by equipping with a traction device. Vehicles equipped with a traction device often adopt a fixed connection, which to a certain extent affects the original vehicle functions, and is not convenient for disassembly, thus inconvenient for maintenance and affecting the convenience. Moreover, the existing tractors lack an auxiliary parking device. When the vehicle is on a slope or soft ground, it is difficult to achieve reliable parking and fixation solely by relying on the traction device, and there is a risk of secondary vehicle rollback.

[0071] To solve the above problems, the present invention provides a tractor 1, such as Figure 1 and Figure 2 As shown, a tractor 1 includes a frame, a front traction device 2, a rear traction device 3 and an auxiliary parking device 50, wherein the front traction device 2 is detachably connected to the front end of the frame; the rear traction device 3 is detachably connected to the rear end of the frame; the auxiliary parking device 50 includes an anchor bracket 51 and an anchor mechanism 52, the anchor bracket 51 is connected to the rear traction device 3, and the hinged end of the anchor mechanism 52 is hinged to the anchor bracket 51, and the anchor mechanism 52 can rotate between an avoidance position and an auxiliary parking position relative to the anchor bracket 51, and the anchor mechanism 52 is used to be rotated to the avoidance position, and the auxiliary parking end of the anchor mechanism 52 is away from the ground, and the anchor mechanism 52 is used to be rotated to the auxiliary parking position, and the auxiliary parking end is inserted into the ground to realize auxiliary parking.

[0072] By providing detachable traction devices at both the front and rear ends of the tractor 1, the tractor 1 has multiple operation modes, including a separate operation mode, a single operation mode, and a combined operation mode. In the separate operation mode, the tractor 1 works alone without connecting the traction device, and the working efficiency of the tractor 1 is higher; in the single operation mode, the tractor 1 is only connected to the front traction device 2 or the rear traction device 3, and the empty rear end or front end can be connected to other agricultural implements, so that the tractor 1 can be applied to a variety of agricultural scenes; in the combined operation mode, the front and rear ends of the tractor 1 are respectively connected to the front traction device 2 and the rear traction device 3, and if the tractor 1 is stuck in the mud, it can help the tractor 1 to get out of trouble quickly.

[0073] Furthermore, an auxiliary parking device 50 is provided at the rear end of the tractor 1, and the auxiliary parking device 50 realizes parking through a rotatable anchoring mechanism 52, such as Figure 3 As shown, when the anchor mechanism 52 rotates to the avoidance position, the auxiliary parking end of the anchor mechanism 52 is away from the ground and can be stored on the tractor 1. When parking is required, the anchor mechanism 52 can be rotated to the auxiliary parking position, and the auxiliary parking position can be inserted into the ground to help the tractor 1 to park. This rotatable anchor mechanism 52 prevents the anchor mechanism 52 from automatically unfolding due to the driving of the tractor 1; when unfolding is required, the anchor mechanism 52 is rotated until it is inserted into the ground, so that the tractor 1 can be stably parked in place, helping the tractor 1 to tow better.

[0074] In addition, adding a traction device enables the tractor 1 to rescue other equipment or vehicles. Both the front traction device 2 and the rear traction device 3 can adopt a winch structure and can be used to extricate external equipment from trouble. When using the tractor 1 with a traction device for rescue, ensure that the tractor 1 is stationary. Connect the trapped equipment through the traction device. Connect one end of the tow rope to the trapped equipment and the other end to the traction device of the tractor 1. After connection, check whether it is locked. The tow rope can be evenly retracted through the traction device to assist in extricating from trouble.

[0075] It should be noted that when the front traction device 2, the rear traction device 3 and the auxiliary parking device 50 are installed on the tractor 1, the front end of the tractor 1 can be fixed by connecting the tow rope of the front traction device 2 to a fixed object. Cooperating with the auxiliary parking device 5 inserted into the ground can ensure the traction stability of the tractor 1 when the rear traction device 3 pulls an external equipment by retracting the tow rope.

[0076] In some embodiments, the anchoring mechanism 52 includes at least two side support rods 521 and an intermediate support rod 522. The first ends of the side support rods 521 are hinged to the anchoring bracket 51, and the intermediate support rod 522 is connected between the side support rods 521, so that the side support rods 521 can rotate together. Specifically, in this embodiment, the anchoring mechanism 52 includes two side support rods 521. The two side support rods 521 are respectively hinged to both ends of the anchoring bracket 51, and the intermediate support rod 522 is connected between the two side support rods 521, so that the two side support rods 521 can rotate together. A single side support rod 521 is prone to deformation or fracture due to excessive local stress. By using the intermediate support rod 522 to force the side support rods 521 on both sides to move synchronously, the risk of tilting of the anchoring bracket 51 caused by the lag of the unilateral support rod action can be eliminated, ensuring a stable anchoring process. Moreover, if one side support rod 521 is accidentally damaged, the intermediate support rod 522 can still transfer part of the load through the side support rod 521 on the other side, avoiding the complete failure of the anchoring mechanism 52 and effectively improving the safety of the anchoring mechanism 52.

[0077] In some embodiments, the side support rod 521 includes a hinged section 5211, a load-bearing section 5212, and an anchoring section 5213. The first end of the hinged section 5211 is hinged to the anchoring bracket 51, that is, the side support rod 521 is hinged to the anchoring bracket 51 through the hinged section 5211. The first end of the hinged section 5211 is the hinged end of the anchoring mechanism 52. The second end of the hinged section 5211 is connected to the first end of the load-bearing section 5212, and the cross-sectional dimension of the load-bearing section 5212 is larger than that of the hinged section 5211. The anchoring section 5213 includes a connecting portion 5215 and an anchoring portion 5216. The second end of the load-bearing section 5212 is connected to the connecting portion 5215 of the anchoring section 5213. The anchoring section 5213 is inclined such that the distance between the anchoring portion 5216 and the hinged section 5211 is greater than the distance between the connecting portion 5215 and the hinged section 5211. The anchoring section 5213 is the parking assistance end of the anchoring mechanism 52 and is used to insert into the ground for auxiliary parking.

[0078] The cross-sectional dimension of the load-bearing section 5212 is larger than that of the hinged section 5211. The larger cross-sectional area of the load-bearing section 5212 significantly improves the compressive and bending resistance capabilities and adapts to the concentrated ground load. During the forward movement of the tractor 1, the load-bearing section 5212 can be driven by the hinged section 5211. Since the stress decreases as the cross-sectional area increases, it can avoid local overload at the bottom causing deformation or fracture, and can effectively improve the load-bearing capacity, stability, and service life of the anchoring mechanism 52.

[0079] As Figure 3 shown, further, the anchoring section 5213 is inclined relative to the load-bearing section 5212. During the forward movement of the tractor 1, a downward force can be applied to the anchoring section 5213, enabling the anchoring section 5213 to insert into the ground. The distance between the anchoring portion 5216 and the hinged section 5211 is greater than the distance between the connecting portion 5215 and the hinged section 5211. When inserting into the ground, the anchoring portion 5216 first contacts the ground. When the inclined anchoring section 5213 inserts, it pushes the soil to both sides, reducing the direct resistance in the vertical direction and facilitating the better inclined insertion of the anchoring section 5213 into the ground.

[0080] In some embodiments, the two sides of the anchoring portion 5216 are symmetrically provided with chamfers 5214. The chamfers 5214 are used to make the width of the anchoring portion 5216 smaller than the width of the connecting portion 5215, facilitating the insertion of the anchoring portion 5216 into the ground. When inserting into the ground, the anchoring portion 5216 first contacts the ground. The symmetrically arranged chamfers 5214 make the width of the anchoring portion 5216 smaller than the width of the connecting portion 5215. When the anchoring portion 5216 contacts the ground, it has a smaller contact area and can be better inserted into the ground.

[0081] In some embodiments, a reinforcing plate 523 is connected to the connection between the side support rod 521 and the middle support rod 522. The reinforcing plate 523 is inclined, one side is connected to the side support rod 521, and the other side is connected to the middle support rod 522, so that the side support rod 521, the middle support rod 522 and the reinforcing plate 523 form a triangular reinforcing structure to enhance the stability of the anchoring structure. In this embodiment, the reinforcing plates 523 are connected between the two side support rods 521 and the middle support rod 522, so that the anchoring mechanism 52 is evenly stressed and the stability is enhanced.

[0082] In some embodiments, Figure 4 and Figure 5 As shown, the auxiliary parking device 50 also includes a limit member 53, the connection end of the limit member 53 is hinged to the rear traction device 3, specifically, the hinged end of the limit member 53 is hinged to the integrated shell of the traction assembly, and the rotating end of the limit member 53 can rotate in a horizontal position and a vertical position relative to the connection end; the limit member 53 is used to be rotated to a horizontal position, and the rotating end abuts against the anchoring mechanism 52, and the limit member 53 is used to be rotated to a vertical position, and the rotating end is away from the anchoring mechanism 52. When the anchoring mechanism 52 needs to be in an avoidance state, the limiter 53 is rotated to a horizontal position, and the rotating end at this time abuts against the anchoring mechanism 52, stopping the anchoring mechanism 52, so that the anchoring mechanism 52 cannot rotate, and the avoidance state is maintained and stored on the tractor 1; when the anchoring mechanism 52 needs to be switched to a parking assist state, the limiter 53 is rotated to a vertical position, and at this time, the limiter 53 releases the stop on the anchoring mechanism 52, and the anchoring mechanism 52 can rotate until it rotates to the anchoring section 5213 and inserts into the ground for parking.

[0083] In some embodiments, Figure 6 , Figure 7 and Figure 8 As shown, the front traction device 2 includes: a traction unit 10 and a quick-release assembly 20, the traction unit 10 includes an integrated shell 11 and a driving member 111 and a winding member 112 installed on the integrated shell 11, the driving member 111 drives the winding member 112 to rotate to retract and release the traction rope on the winding member 112, the integrated shell 11 is provided with an integrated cavity 113, the winding member 112 is accommodated in the integrated cavity 113, and the driving member 111 is located outside the integrated cavity 113; the integrated shell 11 is used to be detachably connected to the frame of the tractor 1 through the quick-release assembly 20.

[0084] The front traction device 2 is a modular device, which can be quickly installed when needed without changing the original vehicle structure. It only needs to use a snap-on structure to connect the quick-release assembly 20 to the frame of the tractor 1. The front traction device 2 has a simple structure. By accommodating each component in the integrated shell 11, the components are protected and the weight of the front traction device 2 is reduced. At the same time, the driving member 111 drives the winding member 112 to rotate to retract and release the traction rope to apply traction force, so that the front traction device 2 has both lightweight characteristics and traction force, and can achieve efficient towing and escape.

[0085] In some embodiments, the quick-release assembly 20 includes a transverse bracket 21 and a vertical bracket 22, the traction unit 10 is connected to the transverse bracket 21, the first end of the transverse bracket 21 is connected to the tractor 1 through a buckle structure; the vertical bracket 22 is vertically arranged and connected to the second end of the transverse bracket 21. The traction unit 10 is connected to the transverse bracket 21, the vertical bracket 22 is connected to the transverse bracket 21, and the vertical bracket 22 is arranged in front of the front traction device 2, which can protect the front traction device 2 and prevent the front traction device 2 from being damaged by external collisions.

[0086] In some embodiments, the transverse bracket 21 includes a first transverse frame 211, a second transverse frame 212, a first connecting frame 213 and a mounting bracket 214. The first ends of the first transverse frame 211 and the second transverse frame 212 are connected to the tractor 1, and the second ends of the first transverse frame 211 and the second transverse frame 212 are respectively connected to the two ends of the first connecting frame 213. The mounting bracket 214 is connected between the first transverse frame 211, the second transverse frame 212 and the first connecting frame 213, and is used to install the integrated shell 11. The transverse bracket 21 is connected by multiple brackets to avoid using plates to increase weight, thereby achieving lightweight front traction device 2. The brackets can be connected by bolts or welding, which is not specifically limited in this embodiment.

[0087] In some embodiments, the vertical bracket 22 includes a first vertical bracket 221, a second vertical bracket 222, and a second connecting bracket 223. The first ends of the first vertical bracket 221 and the second vertical bracket 222 are connected to the first connecting bracket 213, and the second ends of the first vertical bracket 221 and the second vertical bracket 222 are respectively connected to the two ends of the second connecting bracket 223; the first vertical bracket 221, the second vertical bracket 222, the second connecting bracket 223, and the first connecting bracket 213 constitute a hollow portion 24, and the traction rope on the winding member 112 passes through the hollow portion 24. Similarly, the vertical bracket 22 also adopts the bracket method to avoid using a plate to increase weight. The first vertical bracket 221, the second vertical bracket 222, the second connecting bracket 223, and the first connecting bracket 213 constitute a hollow portion 24, which further reduces the weight of the front traction device 2. At the same time, the traction rope can pass through the hollow portion 24 to connect to external equipment.

[0088] In some embodiments, the quick-release assembly 20 further includes reinforcing rods 23 symmetrically disposed on both sides of the quick-release assembly 20; both ends of one reinforcing rod 23 are respectively connected between the first horizontal frame 211 and the first vertical frame 221, and both ends of the other reinforcing rod 23 are respectively connected between the second horizontal frame 212 and the second vertical frame 222. Using the reinforcing rods 23 to form a triangular stable structure between the horizontal frame and the vertical frame can enhance the stability between the horizontal frame and the vertical frame.

[0089] In some embodiments, the driving member 111 is connected to the side surface of the integrated housing 11 and passes through the side surface of the integrated housing 11 to be connected to the winding member 112 in the integrated cavity 113. The driving member 111 can be hydraulically driven or electrically driven. The driving member 111 is disposed outside the integrated housing 11, which is convenient for controlling the start or stop of the driving member 111 during use.

[0090] In some embodiments, the integrated housing 11 includes a plurality of side plates, and the plurality of side plates enclose an integrated cavity 113 with an opening 114. Specifically, the plurality of side plates are respectively a left side plate, a top plate, a right side plate, a bottom plate, and a rear side plate. The left side plate, the right side plate, the top plate, the bottom plate, and the rear side plate enclose an integrated cavity 113 that is closed on five sides and has an opening 114 on one side. When the integrated housing 11 is installed on the mounting bracket 214, the opening 114 faces the hollow portion 24, and the towing rope passes through the opening 114 and the hollow portion 24 in sequence and is connected to an external device.

[0091] In some embodiments, at least one guiding member 115 is disposed at the opening 114, and the guiding member 115 is used to guide the winding and unwinding direction of the towing rope. In this embodiment, two guiding members 115 are disposed at the opening 114 and are respectively disposed on both sides of the opening 114. Disposing the guiding member 115 at the opening 114 can prevent the rope from being in hard contact with the opening 114 and being worn. After the guiding member 115 is worn, it can be directly disassembled and replaced from the opening 114 without opening the main body of the integrated housing 11.

[0092] In some embodiments, a plurality of lifting rings 116 are provided at the top of the integrated housing 11, and the lifting rings 116 are spaced apart and distributed in the edge area of the top of the integrated housing 11. The lifting rings 116 are used for a lifting device to hook or manual lifting to transfer the traction unit 10. The lifting rings 116 are spaced apart and distributed in the edge area of the top of the integrated housing 11, and the force is uniform when transferring the traction unit 10, avoiding damage to the traction unit 10.

[0093] In some embodiments, such as Figure 9 and Figure 10As shown, the rear traction device 3 includes a traction assembly 40 and a mounting assembly 30; the mounting assembly 30 includes a mounting plate 31, a quick-connect frame 32, and a positioning frame 33 that are connected to the mounting plate 31. The traction assembly 40 is mounted on the mounting plate 31. The quick-connect frame 32 is provided with a quick-connect hole 323 for quick connection with the tractor 1 through a quick-connect pin, and the positioning frame 33 is used for positioning and clamping connection with the positioning member 105 of the tractor 1.

[0094] The traction assembly 40 of the rear traction device 3 and the traction unit 10 of the front traction device 2 can be the same traction equipment, such as a winch or other traction equipment, or different traction equipment, as long as traction can be achieved. The present invention does not impose too many restrictions on this.

[0095] The rear traction device 3 realizes quick disassembly and assembly with the tractor 1 through the mounting assembly 30. The mounting assembly 30 includes a mounting plate 31, a quick-connect frame 32, and a positioning frame 33. The mounting plate 31 is used for mounting the traction assembly 40. The quick-connect frame 32 is connected to the tractor 1 through the quick-connect hole 323 on the quick-connect plate 322 and is positioned and clamped with the suspension 101 of the tractor 1 through the positioning frame 33. This connection method does not require complex tools or a lot of time, significantly improving the operation efficiency, especially in the scenario of frequently replacing agricultural implements. It eliminates the complex link mechanism, has a compact overall structure, reduces the load on the suspension 101 system, and is beneficial to the efficient power transmission of the tractor 1.

[0096] In some embodiments, the quick-connect frame 32 includes: a first main body plate 321 and at least two quick-connect plates 322 provided on the first main body plate 321. Each quick-connect plate 322 is provided with a quick-connect hole 323 for a quick-connect pin to pass through, and the first main body plate 321 is connected to the mounting plate 31. Specifically, during the actual connection process, the suspension 101 of the tractor 1 has a corresponding connection hole 103, and the quick-connect pin sequentially passes through the quick-connect hole 323 and the quick-connect pin to realize the connection between the rear traction device 3 and the tractor 1. Setting at least two quick-connect plates 322 can improve the connection stability. Moreover, by connecting through the quick-connect pin, the rear traction device 3 is allowed to swing freely within a certain angle to adapt to uneven terrain or changes in the posture of agricultural implements, reducing wear or deformation of mechanical components caused by rigid connection.

[0097] In some embodiments, the positioning frame 33 includes a second main body plate 331 and a positioning pin 332. The positioning pin 332 is used for positioning and clamping engagement with the positioning member 105 of the tractor 1. The positioning pin 332 is arranged at the end of the second main body plate 331 along the vehicle width direction of the tractor 1, and the second main body plate 331 is connected to the mounting plate 31. The design of the clamping engagement between the positioning pin 332 and the positioning member 105 can achieve rapid alignment of mechanical components, reduce the adjustment time during installation, and is particularly suitable for scenarios where farm implements are frequently replaced, thus improving the operation efficiency. The positioning pin 332 arranged along the vehicle width direction can prevent the second main body plate 331 from interfering with the positioning of the positioning pin 332, and at the same time can also share the lateral torque generated during the traction operation of the tractor 1, avoiding structural deformation caused by stress concentration.

[0098] In some embodiments, the first main body plate 321 is installed at the upper end of the mounting plate 31, the second main body plate 331 is installed at the lower end of the mounting plate 31, and the first main body plate 321, the second main body plate 331 and the mounting plate 31 enclose an avoidance space for the tractor 1. By reserving the avoidance space, it is ensured that the components of the tractor 1 itself will not come into direct contact with the rear traction device 3 during movement, eliminating component wear, deformation or accidental damage caused by friction or collision; avoiding rigid structures from squeezing key components of the tractor 1 and reducing the risk of failures caused by mechanical interference; when the tractor 1 operates on rough ground, the suspension 101 system needs to frequently adjust the height and angle, and the avoidance space provides physical tolerance for the free movement of the suspension 101 mechanism, ensuring that the rear traction device 3 is always stably connected while not restricting the dynamic adaptability of the tractor 1.

[0099] In some embodiments, both the first main body plate 321 and the second main body plate 331 are arc-transition connected to the mounting plate 31. That is, the first main body plate 321, the second main body plate 331 and the mounting plate 31 can form an integrated structure through connection methods such as welding. Stress concentration points are likely to form at right-angle or sharp-corner joints. Especially under dynamic loads such as the jolting of the tractor 1 and the impact of farm implements, it may cause weld cracking or fatigue fracture of the plate. The arc transition disperses the stress through a smooth curvature, avoids local stress peaks, and improves the fatigue resistance strength and extends the structural life. Moreover, the arc connection has no dead corners, reduces debris adhesion, is convenient for flushing or cleaning, and reduces the maintenance frequency.

[0100] In some embodiments, the traction assembly 40 is connected to the mounting plate 31 through a plurality of connecting members 34, and the plurality of connecting members 34 are spaced apart on the mounting plate 31. In actual use, the connecting member 34 can be a bolt or other components that can achieve connection, and the present invention does not make specific limitations. Using a plurality of connecting members 34 spaced apart can effectively improve the stability of the connection between the traction assembly 40 and the mounting plate 31.

[0101] Specifically, the suspension 101 includes an upper pull rod 102 which has a connection hole 103 thereon. The connection hole 103 can be adapted to the quick connection hole 323 on the quick connection frame 32. A quick connection pin shaft sequentially passes through the quick connection hole 323 and the connection hole 103 to realize the connection between the rear hitch device 3 and the tractor 1; alternatively, the suspension 101 includes a lower pull rod 104 having a positioning member 105. The positioning pin 332 and the positioning member 105 are in clamping and positioning cooperation, and the positioning pin 332 is clamped in the positioning member 105, which can also realize the connection between the rear hitch device 3 and the tractor 1.

[0102] In another embodiment, the suspension 101 includes an upper pull rod 102 which has a connection hole 103 thereon. The connection hole 103 can be adapted to the quick connection hole 323 on the quick connection frame 32. A quick connection pin shaft sequentially passes through the quick connection hole 323 and the connection hole 103 to realize the connection between the rear hitch device 3 and the tractor 1; meanwhile, the positioning pin 332 and the positioning member 105 are in clamping and positioning cooperation, and the positioning pin 332 is clamped in the positioning member 105. The quick connection hole 323 and the positioning pin 332 together realize the connection between the rear hitch device 3 and the tractor 1. The quick connection pin shaft ensures the connection between the upper pull rod 102 and the rear hitch device 3, with high tensile strength; the clamping mechanism of the lower pull rod 104 provides stable support, reduces the risk of loosening during operation, and ensures safety during high-intensity operation.

[0103] The tractor provided by the present invention has a detachable front hitch device and rear hitch device, which can not only help the tractor quickly get out of trouble, but also enable the tractor to have multiple operation modes and be applicable to a variety of agricultural scenarios; an auxiliary parking device is also provided at the rear end of the tractor. When parking is required, the anchoring mechanism can be rotated to the auxiliary parking position. At this time, the auxiliary parking position can be inserted into the ground to help the tractor park, prevent sliding accidents, and increase the safety of parking.
