In one embodiment, scraper bowl 13 pivotables connect two pivotable lift arms that stretch out on vehicle frame 12 15,15 ', have only shown one in Fig. 1.Lift arm 15,15 ' can be set to one or more as required.Lift arm 15,15 ' can activate by two load lifting cylinders, 16 pivotables, also only show a load lifting cylinder 16 in Fig. 1.Scraper bowl 13 is connected with connecting rod 17 pivotables, and connecting rod 17 is connected and controls by swing arm 18 with swing arm 18 pivotables, and the swing of swing arm 18 is controlled by the oil cylinder 19 that is arranged in vehicle frame 12 tops.
As shown in Fig. 2 A and Fig. 3 A, the both sides of scraper bowl 13 are formed with respectively the first otic placode 131 that is positioned at outside and the second otic placode 132 that is positioned at inner side, lift arm 15,15 ' end 151 are between the first otic placode 131 and described the second otic placode 132, lift arm 15,15 ' end 151 are connected with the first otic placode 131 and the second otic placode 132 pivotables by pivot 152, are connected with the pivotable of scraper bowl 13 thereby realize lift arm 15,15 '.Between two lift arms 15,15 ', be welded with crossbeam 20, crossbeam 20 is for swinging in the cross rest arm 18.Wherein, the first otic placode is positioned at outside, the i.e. outside of the more close machine of the first otic placode with respect to the second otic placode.
As shown in Figure 2 A and 2B, when processing machine 10, can adjust the structure of machine 10, make the distance of lift arm 15,15 ' to first otic placode 131 be less than the distance of lift arm 15,15 ' to second otic placode 132, the length L 1 in the gap between lift arm and the first otic placode 131 is less than the length L 2 in the gap between lift arm and the second otic placode 132.Thus, as shown in Figure 2 B, when machine is during in operation, scraper bowl, the scraper bowl 13 that is particularly attached with load tilt, for example, cause lift arm 15 to be positioned at high point, and lift arm 15 ' is positioned at low spot.The outside that is positioned at the lift arm 15 of high point is subject to the pressure of the first otic placode 131 to lift arm side direction, and weld seam 21 places of welding at crossbeam 20 and lift arm 15 thus produce inside compressive stress, direction as shown by arrow A, and the inner side that is positioned at the lift arm 15 ' of low spot does not contact with the second otic placode 132.
As shown in Fig. 3 A and 3B, when processing machine 10, keep lift arm 15, the distance of 15 ' to first otic placode 131 and the second otic placode 132 equates, at lift arm 15, 15 ' and first arranges the first pad 141 between otic placode 131, at lift arm 15, between 15 ' end and the second otic placode 132, place the second pad 142, wherein the thickness of the second pad 142 is less than the thickness of the first pad 141, due to above-mentioned lift arm 15, the distance of 15 ' to first otic placode 131 and the second otic placode 132 equates, therefore lift arm 15, the length in the gap between the lateral wall of 15 ' end and the first otic placode is less than the length in the gap between lift arm end inside wall and the second otic placode.As shown in Figure 3 B, when machine is during in operation, when scraper bowl, the scraper bowl 13 that is particularly attached with load tilt, the outside that is positioned at the lift arm 15 of high point contacts with the first otic placode 131, the outside of lift arm 15 is applied to the pressure of lift arm inner side, direction as shown in Fig. 3 B arrow A, weld seam 21 places between lift arm 15 and crossbeam 20 form compressive stress accordingly.
Easily understand, in the situation that structure allows, distance regardless of the first otic placode 131 and the second otic placode 132 to lift arm 15,15 ' end, can adjust lift arm 15,15 ' and first between otic placode 131 and the size in lift arm 15,15 ' and second gap between otic placode 132 by the first pad 141 with different-thickness and the second pad 142.For example suppose that the first otic placode 131 is to lift arm 15, the distance L 1 of 15 ' end is greater than the second otic placode 132 to lift arm 15, the distance L 2 of 15 ' end, can be at the first otic placode 131 and lift arm 15, one or more the first pads 141 are set between 15 ', at the second otic placode 132 and lift arm 15, one or more the second pads 142 are set between 15 ', wherein the thickness of the first pad 141 is greater than the thickness of the second pad 142, adjust the size in gap between lift arm and the first otic placode 131 and between lift arm and the second otic placode, guarantee lift arm 15, the length in the gap between the lateral wall of 15 ' end and the first otic placode 131 is less than lift arm 15, the length in the gap between 15 ' end inside wall and the second otic placode 132, thereby realize in the time of machine tip, the first otic placode 131 that is positioned at outside contacts with the first pad 141, the lift arm 15 ' that is positioned at low spot does not contact with the second otic placode 132 that is positioned at inner side, thereby the first otic placode 131 that is only positioned at high point contacts with the first pad 141 and the outside of lift arm 15 is applied to the pressure as shown in arrow A direction, thereby the commissure between lift arm 15 and crossbeam 20 forms compressive stress.
Industrial applicibility
The loading attachment of the load of machine provided by the invention is applicable to various machines, such as loader etc.
As shown in Figure 2 B, the lift arm 15 of machine, 15 ' stretches out and passes through the first otic placode 131 from machine 10, the second otic placode 132 is connected with scraper bowl 13 pivotables, when machine 10 makes scraper bowl in the operation of the region of non-flat forms, when the scraper bowl 13 that is particularly attached with load tilts, due to lift arm 15, the length L 1 in 15 ' and first gap between otic placode 131 is less than lift arm 15, the length L 2 in 15 ' and second gap between otic placode 132, therefore the lift arm 15 that is positioned at high point directly contacts with the first otic placode 131 that is positioned at outside, and the lift arm 15 ' that is positioned at low spot does not contact with the second otic placode 132 that is positioned at inner side, thus, scraper bowl 13 applies the pressure as shown in arrow A direction by the first otic placode 131 to the outside of the lift arm 15 that is positioned at high point, thereby 21 places of the weld seam between lift arm 15 and crossbeam 20 form compressive stress.
In the time that machine adopts structure as shown in Figure 3 B, in the time that scraper bowl 13 tilts, due to lift arm 15, the distance of 15 ' to first otic placode 131 and the second otic placode 132 equates, and the thickness of the second pad 142 is less than the thickness of the first pad 141, therefore lift arm 15, the length in the gap between the lateral wall of 15 ' end and the first otic placode 131 is less than lift arm 15, the length in the gap between 15 ' end inside wall and the second otic placode 132, therefore the lift arm 15 that is positioned at high point contacts with the first otic placode 131 that is positioned at outside, and the lift arm 15 ' that is positioned at low spot does not contact with the second otic placode 132 that is positioned at inner side, thus, scraper bowl 13 applies the pressure as shown in arrow A direction by the first otic placode 131 to the outside of the lift arm 15 that is positioned at high point, thereby 21 places of the weld seam between lift arm 15 and crossbeam 20 form compressive stress.
In said structure, because the lift arm 15 ' that is positioned at low spot does not contact with the second otic placode 132 that is positioned at inner side, can not apply to the pressure of lift arm lateral direction lift arm 15 ', thereby can not form tensile stress with weld seam 21 places of lift arm 15 ' welding at crossbeam 20, tensile stress easily causes welding seam breaking.
Above with reference to accompanying drawing, the specific embodiment of the present invention is illustrated, but these explanations should not be construed as limiting the scope of the invention.Improvement or modification that those skilled in the art's instruction according to the present invention is made the above-mentioned specific embodiment, fall into protection scope of the present invention.
