Protection device for sawteeth of agricultural ploughing and soil turning machine

Abstract

The invention relates to the technical field of agricultural mechanical equipment, and discloses a protection device for sawteeth of agricultural ploughing and soil turning machine. The protection device comprises a shell, a hard object detection assembly is fixedly connected to the exterior of the shell, an outlet is formed in the surface of the shell, a chain wheel is movably connected to the interior of the shell, and a chain is movably connected to the exterior of the chain wheel. The exterior of the chain is movably connected with a moving block; and under the interaction of the hard object detection assembly, the outlet, the chain wheel, the chain, the moving block, a sliding rail, a first detection assembly, a second detection assembly, a sliding block, a sliding rod, a supporting plate, a protective shell, a magnetic strip, an electromagnet, a rotating shaft, a crushing plate and a tool bit, the service life of the agricultural ploughing and soil turning machine can be remarkably prolonged. Meanwhile, economic losses, caused by collision between the soil turning machine and the hard object, to a user are also avoided, so that the agricultural ploughing and soil turning machine has a self-protection function to a certain extent, and the intelligence of the agricultural ploughing and soil turning machine is also improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a sawtooth protection device for an agricultural land tiller. Background technique [0002] Agricultural machinery refers to various machinery used in the process of crop planting and animal husbandry production, as well as in the process of primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and Fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, the existing agricultural land tiller is often used for agricultural tillage, but the existing tiller is in During the use of cultivated land, the saw teeth are prone to strong collis...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a protection device for the sawtooth of an agricultural tiller, which has the advantages of automatic detection, automatic crushing, improved service life of the sawtooth, and reduced use cost of the tiller. The saw teeth of the soil tiller are easy to collide with hard objects such as stones and irons hidden in the cultivated land during the use of the cultivated land, which will damage the saw teeth of the agricultural tiller due to the collision, and even break the saw teeth. The damage to the equipment of the agricultural land tiller will seriously affect the operation process and efficiency of the tillage, and it will also bring the cost of maintenance equipment to the user and cause economic losses.
