Abstract

The utility model provides a combined counterweight device of a small excavator, which relates to the technical field of counterweight of the excavator and comprises a counterweight box, wherein a placing groove is formed in the counterweight box, a baffle plate is arranged on the inner wall of the placing groove, a clamping groove is formed in the surface of the baffle plate, a stop block is arranged in the clamping groove, and a counterweight block is placed in the placing groove.

Description

Combined counterweight device of mini-excavator

Technical Field

The utility model relates to the technical field of excavator weights, in particular to a combined type weight device of a small excavator.

Background

An excavator, also called an excavating machine, is an earth machine which excavates materials higher or lower than a bearing surface by a bucket, loads the materials into a transport vehicle or unloads the materials to a storage yard, and the materials excavated by the excavator are mainly soil, coal, silt and soil and rock after pre-loosening.

As shown in fig. 1, in the conventional counterweight device for an excavator, the weight of the counterweight device is used to assist the excavator to keep the excavator stable during working, but the weight of the counterweight during working of a small excavator is fixed and cannot be changed according to the load intensity during working, if the counterweight is large, the counterweight can become the load of the excavator during the action when the excavator is not loaded, so that the excavator moves unstably during the action, and when the counterweight is small, the center of the excavator is unstable when the excavator bears the load, the excavator is easy to roll over or shake greatly during the action, and normal use of the excavator is affected.

Disclosure of Invention

The utility model aims to solve the following problems in the prior art:

the existing excavator counterweight device utilizes the weight of the counterweight device to assist the excavator to keep stable during working, however, the counterweight weight during working of a small excavator is fixed and cannot be changed according to the load intensity during working, if the counterweight is large, the counterweight can become the burden of the excavator during the action process when the excavator is not loaded, so that the excavator does not stably act during the action process, when the counterweight is small, the center of the excavator is unstable when the excavator bears the load, the excavator is easy to roll over or shake greatly during the action process, and normal use of the excavator is affected.

The utility model provides a combined counterweight device of a mini excavator, which aims to solve the problems in the prior art and comprises a counterweight box, wherein a placing groove is formed in the counterweight box, a baffle plate is arranged on the inner wall of the placing groove, a clamping groove is formed in the surface of the baffle plate, a stop block is arranged in the clamping groove, and a counterweight block is placed in the placing groove.

Preferably, the placing groove is divided into four independent containing cavities by the partition plate, and balancing weights are placed in each containing cavity.

Preferably, the number of the partition boards is three, and the partition boards are respectively arranged inside the placing groove.

Preferably, a groove matched with the clamping groove is formed in one side, close to the clamping groove, of the balancing weight, and the groove and the clamping groove can be combined into a complete circular groove.

Preferably, the two ends of the stop block are attached to the inner wall of the clamping groove, and the stop block is connected with the partition plate through bolts.

Preferably, a connecting component is arranged at the top of the weight box, and a fixed counterweight is arranged at one side of the weight box, which is close to the connecting component.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the overall weight of the weight box is changed by placing the weight block in the weight box so as to achieve the effect of weight change of the excavator, the weight block can be limited by the stop block in the clamping groove, the condition that the weight block can not shake to influence the normal work of the excavator in the action process of the excavator is ensured, and the position of the weight block can be changed when the excavator works on a special ground such as a muddy road and passes through a cliff side road, so that the overall center of the excavator is adjusted, and the safety and stability of the excavator in the special ground work are improved.

Detailed Description

In order that the manner in which the above recited features, objects and advantages of the present utility model are obtained, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Based on the examples in the embodiments, those skilled in the art can obtain other examples without making any inventive effort, which fall within the scope of the utility model.

Specific embodiments of the present utility model are described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1 to 4, a combined counterweight device for a mini-excavator is assembled by the following components:

and (3) assembly description: firstly, a placing groove 2 is formed in a weight box 1, a partition plate 3 is installed in the placing groove 2, a clamping groove 4 is formed in the surface of the partition plate 3, a stop block 5 is installed in the clamping groove 4, and finally a balancing weight 6 is installed in the placing groove 2.

Description of working principle: firstly, when the counterweight box is used, the stop block 5 is rotated to be vertical to the partition plate 3, then the counterweight block 6 is enabled to be in the placing groove 2 separated by the partition plate 3, then the stop block 5 is rotated to be in a horizontal state in the clamping groove 4, the stop block 5 enters the groove on the surface of the counterweight block 6, and the counterweight block 6 is limited in the placing groove 2, so that the whole weight of the counterweight box 1 is changed.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present utility model, and are not intended to limit the utility model, and that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as claimed.
