Detailed description of the invention
Describe the present invention below in conjunction with drawings and Examples:
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the detailed description of the invention in the embodiment of the present invention is described,
Embodiment 1: as shown in Figure 1-Figure 3, the present invention includes vehicle frame 1, link, test bracket 4, driving mechanism, drive mechanism and mapping mechanism 6, described test bracket 4 one end is connected on vehicle frame 1 by connecting rod, the other end connects mapping mechanism 6, driving mechanism is placed on vehicle frame 1, wheel by drive mechanism connecting vehicle frame 1, described mapping mechanism 6 includes power transmission shaft 66, axle sleeve 65, mapping pole 64 and mapping rod member, axle sleeve 65 is arranged on power transmission shaft 66 one end, described mapping pole 64 one end is arranged on axle sleeve 65, other end correspondence UUT 5 mapped point is provided with mapping rod member, mapping rod member is fixed with plotting pen 67；During mapping, the power transmission shaft 66 of mapping mechanism installs UUT 5, makes the axle sleeve 65 can with identical angular velocity coaxial rotation with UUT 5；Arranging diagram paper on the soil box wall of plotting pen 67 end, plotting pen 67 contacts with diagram paper, thus drawing movement locus.
This example UUT 5 is the cutting disc of spiral of Archimedes type, and described mapping rod member is three 61,62,63, distinguishes two terminal circle acnode and the mid-point position thereof of corresponding Archimedes spiral cutter.Between each mapping pole, mutually offset angular is arranged, and the mapping rod member on three mapping poles 64 to stretch out end face in the same plane, to draw movement locus simultaneously.Described mapping pole 64 is threaded rod, and mapping rod member is connected by nut with mapping pole 64.
Frame is the main body of disk stubble breaking knife cutting corn stubble kinetic characteristic test device.As it is shown in figure 1, frame is made up of vehicle frame 1, link, test bracket 4.The link three point attachment that vehicle frame 1 is consisted of three connecting rods 2 with test bracket 4.The driving mechanism being made up of motor 9, reductor 8 is installed in vehicle frame 1, is connected by the first driving-chain 11 of drive mechanism between the two, connected by the second driving-chain 12 of drive mechanism between reductor 8 and the axis of rolling 3.Described test bracket 4 upper end is with triangle frame, and lower one end is with two connecting rods connecting power transmission shaft 66, and the point of intersection of triangle frame connects three connecting rods 2 of link respectively.Described link includes three connecting rods 2 being connected respectively with test bracket 4 and vehicle frame 1, connecting rod 2 in upper end and be connected to spring 13 between the vehicle frame 1 of end link under connecting, keep embedded depth stable being automatically adjusted UUT 5, the each part of frame is welded by angle bar and rectangular tube, and is bolted.Whole plant running smoothness and stability thereof is ensured with this.
The operation principle of the present invention:
The present invention is laboratory experiment test device, as shown in Figure 1, when mapping, place this invention on experiment soil box, motor 9 provide power, make sprocket wheel rotate, by the first driving-chain 11 deceleration transmission and the second driving-chain 12 transmission, make the axis of rolling 3 with certain rotational speed, thus band motor car wheel 10 advances, make dolly advance with corresponding speed.By link connecting test support 4 and mapping mechanism, cutting disc to be measured, making cutting disc move in soil box, simulating cut corn stubble, the movement locus of the some tested points on cutting disc is drawn by the mechanism of mapping simultaneously, completes test.
