Multifunctional soil loosener

Abstract

The invention discloses a multifunctional soil loosener which comprises a rack, a soil loosening cutter assembly, a push rod and walking wheels. The rack is provided with a machine shell, a motor and a clutch are arranged in the machine shell, and a deceleration mechanism is arranged at the bottom of the rack. The soil loosener further comprises a first auxiliary wheel, a slotting cutter assembly, a trimming cutter assembly and a grass combing cutter assembly, and the slotting cutter assembly, the trimming cutter assembly, the grass combing cutter assembly and the soil loosening cutter assembly can work alternately. The soil loosening cutter assembly comprises a first sleeve and a soil loosening blade set fixedly arranged outside the first sleeve in a sleeving mode. The slotting cutter assembly comprises a second sleeve and a slotting blade set fixedly arranged outside the second sleeve in a sleeving mode. The trimming cutter assembly comprises a third sleeve and a cutter head fixedly arranged on the third sleeve. The grass combing cutter assembly comprises a grass combing wheel, a plurality of installation grooves are formed in the grass combing wheel, protruding columns are arranged in the installation grooves, and grass combing torsion springs are arranged on the protruding columns in a sleeving mode. The multifunctional soil loosener is simple and reasonable in structure, convenient to operate, multifunctional, low in use cost, convenient to maintain, little in damage to lawns during grass combing, long in service life and stable in work performance.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a multifunctional scarifier. Background technique [0002] With the continuous advancement of science and technology, small-scale agricultural production and gardening industries continue to adopt new mechanical devices for production work. For example, scarifiers are widely used by people to turn soil or loosen soil because they can reduce labor. Strength, so it is deeply loved by people. The structure of the common scarifier on the market mainly comprises frame, soil scarifier assembly, the push rod that is fixedly arranged on the frame, the walking wheel that is rotatably arranged on the lower part of the push rod, and the machine frame is provided with an organic casing. A motor and a clutch connected with the motor transmission are respectively installed in the shell, and a speed reduction mechanism is arranged at the bottom of the frame, the input end of the...

AI Technical Summary

Problems solved by technology

However, the defect of the existing scarifiers is that the function is relatively single, and it can only loosen the soil during work, but cannot perform operations such as slotting, trimming, and combing. Specifically, when the user needs to slot the land or lawn It usually needs the help of a slotting machine, when the edge of the lawn needs to be trimmed, it usually needs the help of a trimmer, and when the lawn needs to be combed, it usually needs the help of a combing machine, which not only increases the cost of use At the same time, due to the increase in the number of agricultural machinery, subsequent maintenance and maintenance are also inconvenient, which leads to greater limitations in use and cannot meet the actual needs of users.

[0003] In addition, because the combing wheel of the existing grass combing machine uses a steel combing part, it will cause great damage to the lawn during use, and when the combing part comes into contact with hidden stones in the lawn, the combing wheel will easily get stuck. The phenomenon of stagnation will not only easily cause damage to the combing parts, but also may cause failure of the transmission system and affect the normal use of the machine
