Abstract
The invention relates to a novel friction and wear test machine for agricultural implements and belongs to the application field of tribology test. The invention solves a problem that a conventional friction and wear test machine for the agricultural implements has single function, low efficiency, and poor comparison analysis and low reliability of a test result. In a transmission system, a gear and a V-type belt are combined to achieve transmission, so that the test machine has compact structure, stable transmission and high efficiency. Two rotary brackets on a work part are arranged in a vertically crossed manner, wherein two test sample fixtures are respectively mounted to two ends of one rotary bracket while two soil returning and compacting mechanisms are respectively mounted to two ends of the other one rotary bracket. The test machine is mainly used for simulating the friction and wear situation of two agricultural implements with soil under the same work condition, so that the test machine has great application value in the wear test for the agricultural implements.
Description
Technical field
The invention belongs to Tribological Test application, relate to a kind of agricultural machinery and implement friction wear testing machine, the agricultural machinery and implement friction wear testing machine that the occasion tested for realizing two kinds of different agricultural machinery and implement samples to carry out under same operating simultaneously provides a kind of compact conformation, transmission is steady, efficiency is high, dependable with function is strong.
Background technology
Traditional agricultural machinery and implement friction wear testing machine, mostly it is accomplished that the linear reciprocation abrasion in plane, function and structure are single, realize the friction-wear test of a kind of agricultural machinery and implement sample and soil only simultaneously, need dismounting to change sample when carrying out next group sample again, and then test efficiency is low, and cause the disunity of experimental condition due to the disunity of two groups of test period sections, be so unfavorable for the comparative analysis of two kinds of sample wear results. It is of great significance accordingly, it is capable to produce a kind of two groups of samples of energy wear test simultaneously, efficiency height and lower-cost agricultural machinery and implement friction wear testing machine tool.
Summary of the invention
1, in order to solve the low shortcoming of reliability of testing machine function singleness, inefficient and simulation, the actual demand that the present invention accordingly produces, it is proposed to a kind of agricultural machinery and implement friction wear testing machine just can meet these requirements.
2, the technical solution adopted for the present invention to solve the technical problems is: a kind of agricultural machinery and implement friction wear testing machine includes: drive system is made up of motor, spur gear, V-type band, bevel gear and power transmission shaft, experimental enviroment steadily will not be caused too big vibration by transmission, and efficiency is high. Working portion is by runing rest, two specimen holders, two times soil and two system for compacting compositions, multiple screwed holes (see Figure of description 2,3) are designed in Hui Tu mechanism and system for compacting differing heights place, so regulate height by holding screw, control back the tightness of soil amount and compacting.
3, the invention has the beneficial effects as follows, rational Design of Transmission System so that the compact conformation of testing machine, cost is low, and stable drive, and efficiency is high; Being advantageously used in two groups of tests to carry out, by the Experimental Comparison analysis of same period, result is more reliable simultaneously.

Detailed description of the invention
The present invention reaches required function requirement in conjunction with accompanying drawing and testing machine, and the description of concrete operations is as follows.
As shown in the figure 1, this mechanism mainly includes electric machine support (1), motor (2), shaft coupling (3), spur gear (4), V-type band (5), bevel gear (6), power transmission shaft (7), runing rest (8), pin rod (9), frame and soil box connecting bolt (10), specimen holder (11), soil box (12), soil (13), first Hui Tu mechanism (14), second Hui Tu mechanism (16) and system for compacting (15) composition (include two system for compacting in this testing machine, owing to the two is be distributed in transverse slat both sides in 180 ° in rotary space, therefore Figure of description 1 only depicts the first system for compacting (15)).
Motor (2) turn spur (4) rotates, and then through by V-type band (5) transmission, compact conformation, and V-type band is non junction transmission band, so transmission is relatively steady, finally drives power transmission shaft (7) to rotate around its vertical axis via bevel gear.
Runing rest (8) is connected with horizontal cross plate by fixing bolt, horizontal cross plate is welded in power transmission shaft (7), two agricultural machinery and implement samples on fixture are bolted on runing rest (8), (see Figure of description 1) is rotated around vertical axis with power transmission shaft (7), contact friction with soil after, certain groove can be formed, soil returning plate (21) following closely is connected (see Figure of description 2) with vertical axes (19) by spring support (20), Hui Tu mechanism and system for compacting are separately fixed on another transverse slat of square crossing entirely through screw, jointly rotate around vertical axis with power transmission shaft (7), can by groove, it be filled and led up and compacting rapidly, can also according to practical situation, the upper-lower position adjusted between vertical axes (19) and vertical sleeve (18) by holding screw (17) controls Hui Tuliang. firming roller (27) and be connected (see Figure of description 3) with have employed shaft coupling (26) between rectangle support (25), in process of the test, holding screw (22) can be passed through adjust the upper-lower position between vertical axes (24) and vertical sleeve (23) and control the tightness of firming so that it is consistent with the farm environment of agricultural machinery and implement actual job. another group agricultural machinery and implement sample, Hui Tu mechanism and the system for compacting that rotate can repeat identical process, by such repetition test, it is achieved with the fretting wear of soil while of two groups of agricultural machinery and implement samples.
