Problems solved by technology

[0005] The existing steel pipe cutting devices for agricultural machinery are generally cut manually, which requires the staff to constantly adjust the cutting position, which is time-consuming and laborious, and the internal fixing device cannot be automatically adjusted according to the change of the length of the steel pipe, and the staff needs to manually adjust , At the same time, after the cutting is completed, the method of manual cutting is also used, which increases the labor intensity of the staff and reduces the work efficiency
[0006] Therefore, in order to solve this problem, it is necessary to develop and design a steel pipe cutting device for agricultural machinery, which solves the problem of low work efficiency in the existing steel pipe cutting device for agricultural machinery

Embodiment 1

[0031] see Figure 1 to Figure 3 , a steel pipe cutting device for agricultural machinery, comprising a cutting knife 33, a clamping device 32, a push plate 11, a workbench 24, a rack 2 and a gear 4, the cutting knife 33 is connected to an asynchronous motor 9 through a motor shaft, and the The asynchronous motor 9 is connected to the hydraulic cylinder 7 through the hydraulic strut 8, and the hydraulic cylinder 7 drives the cutting knife 33 to move up and down through the hydraulic strut 8 to realize the function of automatic height adjustment, which has the characteristics of good flexibility. 6 is connected to the slide table 5, and the slide block 6 is slidably connected in the slide rail opened on the surface of the beam 3, and the third servo motor 34 embedded on the top of the slide table 5 is connected to the gear 4 through the motor shaft, and the gear 4 is connected to the frame 1. The racks 2 inlaid on the top mesh with each other. Using the meshing transmission pri...

Embodiment 2

[0039] see figure 1 and Figure 5 , a steel pipe cutting device for agricultural machinery, also includes a push plate 11, the push plate 11 includes a fixed bottom plate 111, a rubber block 112, a fixed pin 113 and a shock-absorbing spring 114, and the fixed pin embedded in the surface of the rubber block 112 113 is embedded in the through hole provided on the surface of the fixed base plate 111, and the surface of the fixed pin 113 is sleeved with a shock absorbing spring 2 114, the rubber block 112 can prevent the surface of the steel pipe from being scratched, and plays a protective role, and the shock absorbing spring 2 114 can weaken The rubber block 112 is subjected to lateral force from the steel pipe to prevent it from being damaged and prolong the service life.

Embodiment 3

[0041] see figure 1 and Figure 4 , a steel pipe cutting device for agricultural machinery, further comprising a workbench 24, a support plate 291 is embedded in a shock absorbing cavity 241 inlaid at the bottom of the workbench 24, and the support plate 291 is connected to the base 22 through outriggers 29 under the support plate 291, The top of the support plate 291 is connected to the inner wall of the shock-absorbing cavity 241 through a shock-absorbing spring-292. The shock-absorbing spring-292 can weaken the longitudinal force received by the shock-absorbing spring-292 from the workbench 24 in violent shaking, preventing it from breaking and supporting The legs 29 and the base 22 play a supporting role, which improves the stability.

[0042] The rest of the structure of this embodiment is the same as that of Embodiment 1.

[0043] The working principle of the present invention is: first put the steel pipe into the clamping device 32 to fix it, then start the hydraulic ...

An asynchronous motor connected with the cutting knife through a motor shaft is connected with a hydraulic cylinder through a hydraulic supporting rod, the hydraulic cylinder is connected with a sliding table through a sliding block, athird servo motor at the top of the sliding table is connected with the gear through a motor shaft, the gear is engaged with the rack, the side wall of a push rod fixedly connected with the end of the push plate is connected with the upper end of a first connecting rod through a shaft pin, the lower end of the first connecting rod is connected with one end of a second connecting rod through a shaft pin, the other end of the second connecting rod is connected with a fixing frame through a shaft pin, a driving rod is slidably connected into a sliding groove formed in the side wall of the secondconnecting rod, the end of the driving rod is connected with a first servo motor through a driving shaft, and the clamping device on the surface of the worktable is connected with a two-way screw through a nut base. The device has the characteristic of high working efficiency.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a steel pipe cutting device for agricultural machinery. Background technique [0002] Agriculture is an industry that produces food and industrial raw materials by cultivating animals and plants. Agriculture belongs to the primary industry. The science of agriculture is agronomy. The labor objects of agriculture are living animals and plants, and the products obtained are animals and plants themselves. We use the growth and development laws of animals and plants to obtain products through artificial cultivation. The various departments of the agricultural sector are collectively referred to as agriculture. Agriculture is the basic product that supports the construction and development of the national economy. Agriculture is a production department in which people use the living functions of animals and plants to transform the substances and energy in n...
