Cement concrete block for fixing the center frame of the sprinkler

Abstract

The invention discloses a cement concrete block for fixing a center frame of an irrigator. The cement concrete block comprises four bottom blocks. Each bottom block is provided with a plurality of balancing weights, four foundation bolts for connecting footings of the center frame with the bottom blocks, and four center bolts for connecting the bottom blocks with the balancing weights overlapped on the upper portions of the bottom blocks. The bottom blocks are prefabricated square cement blocks which are internally provided with reinforcement cages. A center sleeve is arranged in the center of each bottom block and penetrates through the upper and lower bottom faces of the bottom block. A center nut is fixed in each center sleeve. A footing sleeve is arranged at the center position of the connecting line between the center of the upper bottom face of each bottom block and one corner of the corresponding bottom face and penetrates through the upper and lower bottom faces. A footing nut is fixed in each footing sleeve. The balancing weights are the prefabricated square cement blocks which are internally provided with the reinforcement cages and each provided with a chamfer, and the center sleeve which penetrates through the upper and lower bottom faces is arranged at the center position of the non-chamfered diagonal line of each upper bottom face. By adopting the concrete block for fixation, footing pits do not need to be excavated, installation is convenient, the cost is low, and the problem that construction is unavailable in winter is avoided.

Description

technical field

[0001] The invention belongs to the technical field of sprinkler irrigation machinery, in particular to a cement concrete block for fixing the center frame of the sprinkler irrigation machine. Background technique

[0002] The center frame of the circular sprinkler needs to be fixedly installed on the ground near the water source. The installation methods of the prior art are all fixed by anchor bolts. The foundation pits are dug at the four feet of the center frame, and welding is placed in the foot pits. A steel cage with anchor bolts, and then pour cement into the foundation pit, and after the cement hardens, connect the four corners of the center frame to the corresponding anchor bolts.

[0003] Its disadvantages are: the winter in northern my country is cold, the ground is frozen, and it is very difficult to dig the foundation pit; the quality of the anchor bolts fixed by pouring concrete at subzero temperatures cannot be guaranteed; the construction of ...
