[0005] The counterweight module for a loader provided by this utility model adopts the following technical solution: A counterweight module for a loader includes a counterweight body installed at the rear end of the loader. The counterweight body houses multiple separate counterweight boxes, each with a weighing mechanism installed at its bottom. Loading boxes are fixedly connected to both sides of the counterweight body, and the loading boxes are capable of loading equipment.
[0006] Preferably, the weighing mechanism includes a weighing platform disposed at the bottom of the split counterweight box, and a weighing sensor is fixedly installed at the bottom of the weighing platform, the weighing sensor being communicatively connected to an external controller.
[0007] Preferably, the separate counterweight box contains the counterweight material, and multiple separate counterweight boxes are arranged and installed inside the counterweight body. A top plate is movably provided on the top of the counterweight body. The top plate is open and closed relative to the counterweight body. When the top plate is open, the separate counterweight boxes are put in and taken out.
[0008] Preferably, the counterweight body has a support frame at the location where the separate counterweight box is not installed.
[0009] Preferably, the counterweight body and the loading box are an integrated structure.
[0010] Preferably, a cover plate is movably connected to one end of the top of the loading box via a hinge, and a support mechanism is provided at the movable connection position to support the lifted cover plate.
[0011] Preferably, the support mechanism includes a support rod, one end of which is rotatably mounted on the inner side wall of the loading box. A vertical plate is fixedly provided at the bottom of the cover plate, and a groove is provided on the vertical plate that conforms to the movement trajectory of the end of the support rod. During the process of lifting the cover plate, the end of the support rod slides down along the groove and finally gets stuck into the abutment groove at the end of the groove.
[0012] Preferably, the movable end of the cover plate is provided with a locking pin, and the loading box is provided with a pin hole at the position corresponding to the locking pin. When the cover plate is closed, the locking pin is inserted into the pin hole to lock it.
[0013] In summary, this utility model has the following beneficial technical effects: 1. This utility model houses multiple separate counterweight boxes inside the counterweight unit body.

[0017] The following combination Figures 1-5 The present invention will be described in further detail below.
[0018] Utility Model Embodiment 1 discloses a counterweight module for a loader.
[0019] Reference Figure 1 , Figure 3 , Figure 4 A counterweight module for a loader includes a counterweight body 1 installed at the rear of the loader. The counterweight body 1 balances the weight of the load loaded by the loader to prevent the loader from tipping over. The counterweight body 1 contains multiple separate counterweight boxes 2. A weighing mechanism 3 is installed at the bottom of the separate counterweight boxes 2. Loading boxes 4 are fixedly connected to both sides of the counterweight body 1. The loading boxes 4 can hold equipment such as oil tanks, oil pumps, hydraulic pumps and other functional modules.
[0020] Reference Figure 2 , Figure 3 The weighing mechanism 3 includes a weighing platform 5 set at the bottom of the split counterweight box 2. A weighing sensor 6 is fixedly installed at the bottom of the weighing platform 5. The weighing sensor 6 is connected to an external controller 7. The weighing sensor 6 detects the weight of the split counterweight box 2 in real time and transmits the weight information to the controller 7. The controller 7 receives the weight information and feeds it back, displaying the weight information on the display screen on the surface of the controller 7.
[0021] Reference Figure 3 The separate counterweight box 2 holds the counterweight material inside. The counterweight material can be sand, gravel or metal scrap, or it can also hold concrete counterweight material. Multiple separate counterweight boxes 2 are arranged and installed inside the counterweight body 1. The top of the counterweight body 1 is movably provided with a top plate 8. The top plate 8 is open and closed relative to the counterweight body 1. When the top plate 8 is open, the separate counterweight boxes 2 are put in and taken out, realizing flexible addition and reduction of counterweight and improving the adaptability with different loader operating equipment such as light buckets or heavy breakers.
[0022] Reference Figure 3 Inside the main body 1 of the counterweight unit, where the separate counterweight box 2 is not installed, there is a support frame 9. The shape of the support frame 9 is the same as that of the separate counterweight box 2. The support frame 9 is supported in the corresponding position to prevent the counterweight box 2 from shaking.
[0023] Reference Figure 1 The counterweight body 1 and the loading box 4 are an integrated structure. The loading box 4 is assembled and welded using mounting plates. The two side plates of the counterweight body 1 extend forward and are enclosed and fixed with the mounting plates to form the main structure of the loading box 4.
[0024] Reference Figure 1 , Figure 4 , Figure 5The top end of the loading box 4 is movably connected to a cover plate 13 via a hinge 12. A support mechanism 14 is provided at the movable connection position to support the lifted cover plate 13. A locking pin 10 is provided at the movable end of the cover plate 13. A pin hole 11 is provided at the position of the locking pin 10 in the loading box 4. When the cover plate 13 is closed, the locking pin 10 is inserted into the pin hole 11 and locked by a lock.
[0025] Reference Figure 4 , Figure 5 The support mechanism 14 includes a support rod 15. One end of the support rod 15 is rotatably mounted on the inner side wall of the loading box 4. A vertical plate 16 is fixedly installed at the bottom of the cover plate 13. A groove 17 is opened on the vertical plate 16 to conform to the movement trajectory of the end of the support rod 15. During the lifting of the cover plate 13, the end of the support rod 15 slides downward along the groove 17. When the cover plate 13 is lifted to the maximum angle, the end of the support rod 15 is inserted into the abutment groove 18 at the end of the groove 17. The end of the groove 17 has a bent movement trajectory. When the manual force is removed, the cover plate 13 is pressed down, so that the end of the support rod 15 abuts against the abutment groove 18 to form a stable support.
[0026] The implementation principle of a counterweight module for a loader according to this utility model embodiment is as follows: When adjusting the counterweight of the loader, the top plate 8 is opened to put in and take out the split counterweight box 2, so as to realize the flexible increase or decrease of the counterweight. The weight of the split counterweight box 2 is detected by the weighing mechanism 3, and compared and adapted to the loading capacity of different loader operating equipment. When the split counterweight box 2 is too heavy to be lifted by manpower, a hoist or crane can be used for hoisting. At the same time, the operator can open the cover plate 13 on the top of the loading box 4 and support and fix the cover plate 13 by the support mechanism 14 to keep the cover plate 13 in the lifted state for loading equipment installation and replacement operations.
[0027] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
