Description

Technical Field

[0001] The utility model relates to the technical field of tractors, in particular to a combined front counterweight structure and a tractor. Background Technique

[0002] During the agricultural operation of a tractor, it is necessary to adjust the counterweight according to different agronomic requirements, so as to maximize the traction efficiency and save fuel. During heavy-load operations, if the number of counterweights is insufficient, the tires are likely to slip during operation, damaging the soil aggregate structure and causing energy waste, increasing the fuel consumption rate. During light-load operations, if there are too many counterweights, it will cause soil compaction, affecting agricultural yields. At the same time, due to the heavy vehicle weight, it will also cause excessive fuel consumption. Therefore, during agricultural production, it is necessary to adjust the number of tractor counterweights according to agronomic requirements.

[0003] Existing tractor front counterweights have an integral front counterweight method, which is installed as an integral structure through the tractor's front suspension system. However, the weight of this type of front counterweight is not adjustable, and it is impossible to adjust the counterweight according to light-load and heavy-load operations. When a tractor with a front suspension system does not match the front-mounted implement, it is difficult to adjust the mass ratio of the tractor's front and rear axles when installing this type of counterweight. Summary of the Utility Model

[0004] In view of the technical problem that the existing integral counterweight cannot quickly adjust the weight, the utility model provides a combined front counterweight structure and a tractor.

[0053] The principles and features of the present utility model will be described below. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0054] In a first aspect, the present utility model provides a combined front counterweight structure, which is specifically described as follows.

[0055] Embodiment 1

[0056] As Figure 1 and Figure 2 , a combined front counterweight structure includes a front counterweight main body 2 detachably connected to a front suspension system 1 of a walkable mechanical device and a front counterweight base 3 disposed on the lower side of the front counterweight main body 2. A plug-in structure is provided between the front counterweight main body 2 and the front counterweight base 3, and the plug-in structure completes the plug-in action as the walkable mechanical device advances.

[0057] The beneficial effect of this embodiment is that after the front counterweight main body 2 is installed on the front suspension system 1, the front counterweight base 3 is placed on the ground. As the mechanical device advances, the front counterweight main body 2 and the front counterweight base 3 are connected through the plug-in structure to complete the increase of the counterweight. It is possible to increase or decrease the front counterweight main body 2 and the front counterweight base 3 according to the demand for counterweight, thus solving the technical problem that the existing integral counterweight cannot quickly adjust the weight.

[0058] Embodiment 2

[0059] As Figures 1 to 5 , on the basis of Embodiment 1, there is one front counterweight base 3, and the front counterweight base 3 is connected to the lower side of the front counterweight main body 2 through a plug-in structure.

[0060] The beneficial effect of adopting the preferred solution in the above embodiment is that the weight of the entire front counterweight structure can be adjusted by increasing or decreasing the front counterweight base 3.

[0061] When the mechanical equipment is operating under light load, only the front counterweight main body 2 is carried. When heavy load operation is required, the front counterweight base 3 is placed on the ground. As the mechanical equipment advances, the front counterweight main body 2 and the front counterweight base 3 are connected through the plug-in structure to complete the weight increase.

[0062] Embodiment 3

[0063] As Figures 1 to 5 , on the basis of Embodiment 1, there are at least two front counterweight bases 3, and the front counterweight bases 3 are stacked up and down. A plug-in structure is provided between the front counterweight main body 2 and the uppermost front counterweight base 3, and a plug-in structure is also provided between adjacent two front counterweight bases 3. The plug-in structure completes the plugging action as the walkable mechanical equipment advances.

[0064] The beneficial effect of adopting the preferred solution in the above embodiment is that after the front counterweight main body is installed on the front suspension system, multiple front counterweight bases 3 are placed on the ground at one time. As the mechanical equipment advances, the front counterweight main body 2 is connected to the uppermost front counterweight base 3 through the plug-in structure and is sequentially connected to other front counterweight bases 3 through the plug-in structure to complete the weight increase. The front counterweight main body 2 and the front counterweight bases 3 can be increased or decreased according to the weight requirement, thus solving the technical problem that the existing integral counterweight cannot quickly adjust the weight.

[0065] When the mechanical equipment is operating under light load, only the front counterweight main body 2 is carried or the number of the front counterweight bases 3 is relatively reduced. When heavy load operation is required, because the increased counterweight is relatively heavy and not easy to install, multiple front counterweight bases 3 are placed on the ground in sequence (preferably, multiple front counterweight bases 3 are arranged at intervals in a straight line), and then the mechanical equipment moves the front counterweight main body 2 forward through the front suspension, and through the plug-in structure carried by the counterweight, the sequential plugging operation of the front counterweight main body 2 and multiple front counterweight bases 3 is completed.

[0066] As a specific solution of the above embodiment, the number of multiple front counterweight bases 3 can be two, three, four, five, etc. In the figure, only one front counterweight base 3 is shown.

[0067] Embodiment 4

[0068] As Figures 1 to 5On the basis of Embodiment 2 or 3, the plug-in structure includes a first plug-in block 4 and a first plug-in slot 41 matched with the first plug-in block 4, and the slot width of the first plug-in slot 41 is smaller than the slot bottom width.

[0069] The beneficial effect of adopting the preferred scheme in the above embodiment is that, as the movable mechanical equipment moves forward, the first plug-in block 4 is inserted into the first plug-in slot from the lateral opening of the first plug-in slot 41, and because the slot width of the first plug-in slot 41 is smaller than the slot bottom width, the front counterweight body 2 and the topmost front counterweight base 3, or the two front counterweight bases 3 are plugged in and hung by the plug-in of the first plug-in block 4, thereby completing the rapid counterweight operation.

[0070] In the embodiment of the utility model, the first plug-in slot 41 can be a dovetail slot or a step slot, and the figure shows a dovetail slot. The first plug-in block 4 can be a corresponding dovetail block or a step block.

[0071] When the first plug-in slot 41 adopts a dovetail slot and the first plug-in block 4 adopts a corresponding dovetail block, the slot depth of the first plug-in slot 41 is less than the thickness of the first plug-in block 4, so that when the first plug-in block 4 is plugged into the first plug-in slot 41, the front counterweight body 2 and the front counterweight base 3, or the two front counterweight bases 3 will not contact each other, thereby reducing friction and facilitating the formation of plug-in.

[0072] On the basis of the above-mentioned embodiment, a plurality of first plugging blocks 4 located on the same plane are arranged at intervals, and a plurality of first plugging slots 41 located on the same plane are arranged at corresponding intervals.

[0075] The beneficial effect of adopting the preferred solution in the above embodiment is that, as the mobile mechanical device moves forward, the first plug-in block 4 is inserted into the first plug-in slot 41 from the front side of the front counterweight body 2 or the front counterweight base 3 .

[0076] In one exemplary embodiment, the first insertion slot 41 does not penetrate through the rear sides of the front counterweight body 2 and the front counterweight base 3 ; in another exemplary embodiment, the first insertion slot 41 penetrates through the rear sides of the front counterweight body 2 and the front counterweight base 3 .

[0077] The front side of the front counterweight body 2 or the front counterweight base 3 refers to the side thereof facing away from the mechanical device.

[0078] likeFigure 6 , as one of the parallel solutions of the above embodiments, the plugging structure includes a plurality of L-shaped rods 5 arranged at intervals. The L-shaped rod 5 includes a vertical rod 51 fixedly connected to the upper side of each front counterweight base 3 at the lower end and a cross rod 52 fixedly connected to one end of the upper end of the vertical rod 51. The other end of the cross rod 52 extends toward the rear end of the front counterweight body 2 or the front counterweight base 3. Second slots 53 adapted to and for inserting the L-shaped rods 5 are formed at the lower ends of the front counterweight body 2 and each front counterweight base 3, and the second slots 53 are open toward the front side of the front counterweight body 2.

[0079] As the front counterweight body 2 advances, the cross rod 52 on the front counterweight base 3 placed on the ground is inserted into the second slot 53.

[0080] The end of the other end of the cross rod 52 is in the shape of a frustum of a cone to facilitate quick insertion into the second slot 53.

[0081] Embodiment 6

[0082] Such as Figure 2 and Figure 3 , on the basis of Embodiment 5, the width of the first plugging block 4 gradually decreases from the front end to the rear end.

[0083] The beneficial effect of adopting the preferred solution in the above embodiment is that it makes it easier for the first plugging block 4 to be inserted into the first plugging slot 41 from the side opening of the first plugging slot 41 to complete the quick plugging operation; at the same time, it prevents the first plugging block 4 from coming out of the first plugging slot 41 as the mechanical equipment advances.

[0084] Embodiment 7

[0085] Such as Figure 2 and Figure 3 , on the basis of Embodiment 6, the thickness of the first plugging block 4 gradually decreases from the front end to the rear end.

[0086] The beneficial effect of adopting the preferred solution in the above embodiment is that it facilitates the first plugging block 4 to be more easily inserted into the first plugging slot 41 from the side opening of the first plugging slot 41.

[0087] Embodiment 8

The first plugging slot 41 is formed on the upper side of each front counterweight base 3 and opens upward, and the first plugging slot 41 also opens toward the rear side of the front counterweight body 2 or the front counterweight base 3.

[0089] The beneficial effect of adopting the preferred solution in the above embodiment is that as the walkable mechanical equipment advances, the first plugging block 4 is inserted into the first plugging slot 41 from the rear side of the front counterweight body 2 or the front counterweight base 3.

[0090] In an exemplary solution, the first insertion slot 41 does not penetrate the front side of the front counterweight body 2 and the front counterweight base 3; in another exemplary solution, the first insertion slot 41 penetrates the front side of the front counterweight body 2 and the front counterweight base 3.

[0091] Wherein, the rear side of the front counterweight body 2 or the front counterweight base 3 refers to the side facing the walkable mechanical equipment.

[0092] Such as Figure 6 , as the second parallel solution of the above embodiment (not shown in the figure), the plugging structure includes a plurality of L-shaped rods 5 arranged at intervals. The L-shaped rod 5 includes a vertical rod 51 fixedly connected to the lower side of the front counterweight body 2 or each front counterweight base 3 at the upper end and a cross rod 52 fixedly connected to one end of the lower end of the vertical rod 51. The other end of the cross rod 52 extends towards the front end of the front counterweight body 2 or the front counterweight base 3.

[0093] Second slots 53 adapted to and for inserting the L-shaped rods 5 are formed at the upper ends of the front counterweight body 2 and each front counterweight base 3, and the second slots 53 open towards the rear side of the front counterweight body 2.

[0094] The other end of the cross rod 52 is in a frustum shape so as to be quickly inserted into the second slot 53.
