Problems solved by technology

The main hazards of the entanglement of weeds and straws by the rotary tiller are: (1) The subsoiling work of the rotary tiller is reduced, which cannot meet the requirements of the tillage depth; (2) After the operation, the ground surface is uneven, and the knife roller drags out a ditch; ( 3) Increase the resistance of rotary tillage, and in severe cases, the rotary tiller will be stuck, which will affect the life of the rotary tiller; (4) It takes time and effort to clean the entangled weeds and straw, which will affect the efficiency of rotary tillage
The existing anti-winding device for rotary tillage can increase the length of sliding cutting of straw and weeds through the auxiliary knife installed in front of the rotary tillage knife seat, and solve the problem of entanglement of rotary tillage tools, but it cannot solve the problem of entanglement of straw and weeds on the knife shaft. Problem, the anti-winding effect is not obvious

Embodiment 1

[0038] Figures 1 to 3 Shown is a preferred embodiment of the cutter shaft anti-grass wrapping device of the present invention. The cutter shaft anti-grass wrapping device includes a drive shaft 1, a left drive system 2, a cutting device 3, a tensioning device 5, and a cutter shaft 9. , the right transmission system 14 and the rotary tiller group 10; the two ends of the transmission shaft 1 are respectively connected with the left transmission system 2 and the right transmission system 14; the cutting device 3 is installed at one end of the cutter shaft 9; The device 5 is installed on both ends of the cutter shaft 9; the left transmission system 2 transmits the power of the transmission shaft 1 to the cutting device 3 and the tensioning device 5; the right transmission system 14 transmits the power of the transmission shaft 1 to the cutter shaft 9 and the tensioning device 5; the cutting device 3 and the tensioning device 5 rotate synchronously with the knife shaft 9, the cutt...

Embodiment 2

[0058] A rotary tiller is characterized in that it includes the blade shaft anti-grass wrapping device described in Embodiment 1, and thus has the beneficial effects of Embodiment 1, which will not be repeated here.

[0059] combine figure 1 and 2 As shown, preferably, the inner sides of the two side walls of the rotary tiller are respectively welded with the first blocking cover 17 and the second blocking cover 18, the left transmission system 2, the cutting device 3 and the tensioning device 5 of the blade shaft anti-wrap device. , the cutter shaft 9, and the right transmission system 14 are installed in the box between the side wall of the rotary tiller and the cover.

[0060] The first blocking cover 17 and the second blocking cover 18 are welded to the inner sides of the two side walls of the rotary tiller respectively, which can play the role of retaining soil and grass, and ensure the stable operation of the anti-winding devices on both sides of the cutter shaft 9 .

Abstract

The invention discloses a device for preventing grass winding of a cutter shaft and a rotary cultivator. The device comprises a transmission shaft, a left transmission system, a cutting device, a tensioning device, the cutter shaft, a right transmission system and a rotary blade group, two ends of the transmission shaft are respectively connected with the left transmission system and the right transmission system; the cutting device is mounted at one end of the cutter shaft; the tensioning devices are mounted at the two ends of the cutter shaft; the left transmission system transmits power of the transmission shaft to the cutting device and the tensioning device. The right transmission system transmits the power of the transmission shaft to the cutter shaft and the tension device; the cutting device and the tensioning device synchronously rotate along with the cutter shaft, the cutting device conducts axial reciprocating motion, and the tensioning device conducts radial reciprocating motion. A transverse cutter of the cutting device does transverse reciprocating motion along a cutter shaft under the action of a cylindrical cam so as to cut weeds. The tensioning rod of the tensioning device does transverse reciprocating motion under the action of the groove cam to pull weeds wound on the cutter shaft, the anti-winding effect is good, the operation stability is high, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of farming in agricultural machinery, and in particular relates to a blade shaft anti-grazing device and a rotary tiller. Background technique [0002] The rotary tiller can complete the tilling and harrowing operation at one time, and is an important tillage machine in my country. One of the main problems affecting the application of the rotary tiller in the straw returning mode is the entanglement of weeds and straws by the rotary tiller shaft. The main hazards of entanglement of weeds and straws by the rotary cultivator are: (1) The deep loosening of the rotary cultivator in the soil work is reduced, which cannot meet the requirements of ploughing depth; (2) After the operation, the surface is uneven, and the knife roller drags out a ditch; ( 3) Increase the resistance of the rotary tiller, and in severe cases, the rotary tiller will be stuck, which will affect the life of the rotary tiller; (4) It is ti...
