the sand digging device comprises a box body 11, a box body 12, a fixed base 13, a fixed front arm 21, a first control rod 22, a second control rod 23, a transmission arm 24, a movable arm 25, a first connecting rod 26, a second connecting rod 27 and a sand digging bucket.

Detailed Description

In order to make the technical solution of the present invention's purpose, technical solution and advantages clearer, the following description will be combined with the drawings of the specific embodiments of the present invention, to carry out clear and complete description on the technical solution of the embodiments of the present invention. Like reference symbols in the various drawings indicate like elements. It should be noted that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive work based on the described embodiments of the present invention, belong to the protection scope of the present invention.

The utility model discloses and in the embodiment "around", "about" all adopt and use fixed baseplate as the fixed point, look to the direction of motion that digs the sand fill and present in the visual angle when digging the sand fill.

When the utility model is implemented, there are several aspects that need to be explained in detail below.

Description of first link setting position: the movable arm 24, the first connecting rod 25 and the first control rod 21 form a double-crank mechanism, according to the principle of connecting rods, when the structure is a double-crank mechanism with two cranks equal in length, i.e. a parallelogram mechanism, the effect of parallel transmission is the best, but because the device is a children toy and the requirement on the control accuracy is not so high, when the double-crank mechanism is an approximate parallelogram, the effective transmission of the movable arm can be achieved. Therefore, the position of the first connecting rod on the movable arm and the first control rod is preferably set to be a double-crank mechanism with equal length of crank, and the effective transmission function can be realized in practical use.

Description of the second link setting position: the transmission arm 23, the second connecting rod 26 and the second control rod 22 form an unequal-length double-crank mechanism, wherein the unequal-length double-crank mechanism is a term of nomenclature, and means that the active radius of a driving crank used as a driver is not equal to the active radius of a driven crank used as a driven crank during transmission. The utility model discloses in, the active crank radius of motion is second control lever 22 and second connecting rod 26's tie point to second control lever 22 and the distance P between the fixed forearm 13 tie point, and driven crank radius of motion is second connecting rod 26 and the tie point of driving arm 23 to the distance Q between driving arm 23 and the fixed forearm 13 tie point. When P is larger than Q, the free operation cannot be realized, so that in the actual design of the sand excavator, the mounting position of the second link 26 adopts a structural design method that Q is larger than P.

The utility model discloses in sand digging machine can set to that drive arm 23 is fixed to be set up on the pedestal is fixed to be served, only control the single control lever sand digging machine that sand bucket 27 back-and-forth movement was dug in the control of digging arm 24 by first control lever 21, also can set to drive arm 23, the equal mobilizable two control lever sand digging machine of moving arm 24. The difference is that the transmission arm 23 is hinged on the fixed end of the seat body or is connected on the fixed end of the seat body by steel. When steel joints are used, the actuator arm 23 may be considered to be a structure integrally formed on the seat body, and thus may be considered to include a fixed forearm extending forwardly and upwardly on the seat body. The seat body of the sand digging machine can also be arranged into a concave seat, in this case, the movement of the control rod is not limited, and the fixed end of the seat body can be only a convex block and does not extend forwards. The control rod, the transmission mechanism and the movable arm of the sand digging machine are respectively one or more flat rods arranged side by side, and the control rod is provided with a handle convenient for children to hold.

The base body of the sand digging machine is preferably designed to comprise a fixed base and a box body hinged on the fixed base, and the moving radius of the whole body in the circumferential direction is increased when the base body is designed. But in actual use, the seat body can also be designed to be in a non-rotatable state. When the seat body is not rotatable, the bottom of the seat body can realize the effect of integral movement by additionally arranging wheels. The wheels can adopt a universal wheel shaft type design, and can also adopt a plurality of tires, as long as the integral movement of the machine body can be realized.

The specific embodiments and effects are shown in specific examples.
