[0001] The utility model relates to the technical field of tractors, in particular to a front counterweight mounting frame for a crawler tractor and the crawler tractor. Background Art

[0002] Tractors are important tools for agricultural and forestry production. Various production operations can be completed by hanging agricultural machinery at the rear of the tractor. In order to ensure the longitudinal stability of the tractor when agricultural machinery is hung at the rear, and to make the tractor have better maneuverability, a counterweight of appropriate weight is hung at the front of the tractor to ensure that the load on the tractor's front wheels is not less than 35%-40% of the total mass.

[0003] Typically, the front counterweight mounting frame used to suspend the front counterweight is a welded structure welded to the front bracket of the tractor. It is light in weight and has poor strength. It can only carry a maximum of 150kg of counterweight, which cannot meet the counterweight requirements of some users carrying large implements. If the implement weighs more than 800kg, the entire machine will tilt. Utility Model Content

[0004] The utility model aims to solve the technical problem that the existing front counterweight mounting frame cannot meet the counterweight requirements of some users who carry large machines and implements, and provides a front counterweight mounting frame for a crawler tractor and a crawler tractor.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] On the one hand, the utility model provides a front counterweight mounting frame for a crawler tractor, comprising a counterweight plate and a mounting frame detachably connected to the counterweight plate, wherein the counterweight plate is used to be detachably connected to the front bracket, and the mounting frame is provided with a hanging portion for hanging a counterweight block.

[0007] The beneficial effects of the present invention are as follows: the counterweight plate is detachably connected to the front bracket, so that the weight of the counterweight plate itself can meet the normal operation requirements without the counterweight block. When it is used for the purpose of hanging heavy machinery and tools, the detachable connection between the mounting frame and the counterweight plate is realized through a detachable connection method, so that a counterweight block of appropriate weight can be hung on the hanging part of the mounting frame, thereby improving the technical problem that the existing front counterweight mounting frame cannot meet the counterweight requirements of some users carrying large machinery and tools, and reducing the phenomenon of the whole machine tilting when heavy machinery and tools are hung. At the same time, the counterweight plate and the mounting frame are all detachably connected and installed, and the disassembly and assembly method is convenient, and can meet the requirements of working conditions where operation is not possible.

[0016] The beneficial effect of adopting the above further scheme is: when hanging the counterweight block, the counterweight block is hung on the side of the hanging plate away from the front bracket. At this time, the lower end of the counterweight block can enter the avoidance opening, so as to ensure the smooth hanging of the counterweight block through the setting of the avoidance opening.

[0017] Furthermore, it also includes at least two No. 1 bolts, each of which is used to be threadedly connected to the front bracket; the counterweight plate is provided with at least two sockets, and the number of each No. 1 bolt is equal to the number of each socket, and is inserted into each socket one by one.

[0018] The beneficial effect of adopting the above further solution is: when installing the counterweight plate, each No. 1 bolt is inserted into the corresponding insertion hole of the No. 1 bolt and threadedly connected to the front bracket.

[0019] Furthermore, there are at least four No. 1 bolts, which are distributed in an array.

[0020] The beneficial effect of adopting the above further solution is: to ensure that the counterweight plate is stably installed on the front bracket by the connection and fixation through each No. 1 bolt, and to ensure that the counterweight block is stably hung.

[0021] Furthermore, it includes at least one No. 2 bolt; the mounting frame is provided with at least one through hole, and the counterweight plate is provided with at least one internal threaded hole, and each of the No. 2 bolts passes through each of the through holes and is threadedly connected to each of the internal threaded holes.

[0022] The beneficial effect of adopting the above-mentioned further scheme is that when heavy machinery needs to be hung, each through hole and each internal threaded hole are matched one by one, and each No. 2 bolt is tightened to realize the installation connection between the mounting frame and the counterweight plate, and then the counterweight block of appropriate weight can be hung on the hanging part of the mounting frame.

[0023] Furthermore, there are at least four No. 2 bolts, which are distributed in an array.

[0024] The beneficial effect of adopting the above further solution is that after the counterweight block is hung on the hanging plate, the hanging plate will not turn over or move due to the weight of the counterweight block.
