Below with reference to Fig. 1-Fig. 3, the grab bucket-type dredger 10 according to this utility model embodiment is described.As shown in Figure 1-Figure 3, first connecting rod 101, fixed pulley 102, grab bucket 103, movable pulley the 104, first pull bar the 1051, second pull bar 1052, grip part 106 and rope 107 are included according to the grab bucket-type dredger 10 of this utility model embodiment.
Fixed pulley 102 is located on first connecting rod 101.Grab bucket 103 has the first jaw 1031 and the second jaw 1032, and the first jaw 1031 is connected with the second jaw 1032 pivotly.Movable pulley 104 is located in grab bucket 103, and movable pulley 104 is positioned at the lower section of fixed pulley 102.The upper end of the first pull bar 1051 is connected with first connecting rod 101 pivotly, and the lower end of the first pull bar 1051 is connected with the first jaw 1031 pivotly.The upper end of the second pull bar 1052 is connected with first connecting rod 101 pivotly, and the lower end of the second pull bar 1052 is connected with the second jaw 1032 pivotly.First end of rope 107 is connected with grip part 106, and the second end of rope 107 is walked around movable pulley 104 successively and is connected with grab bucket 103 with after fixed pulley 102.
The work process of the grab bucket-type dredger 10 according to this utility model embodiment is described below with reference to Fig. 1-Fig. 3.Before the grab bucket-type dredger 10 according to this utility model embodiment enters water, lift the first pull bar 1051 and the second pull bar 1052, in order to make the first jaw 1031 of grab bucket 103 and the second jaw 1032 open.
When needing to be sampled the benthon in the lakebed matter of river, operator hold with a hand the grip part 106 of grab bucket-type dredger 10, and make grab bucket-type dredger 10 enter at the bottom of water precipitating.When grab bucket-type dredger 10 enters after water bottoms out, upwards lifting grip part 106, in order to upwards lift the first end of rope 107.Be located at grab bucket 103 on movable pulley 104 under the tractive of rope 107, be moved upward to close to fixed pulley 102.
Under the drive of movable pulley 104, grab bucket 103 also moves up.Thus, the first jaw 1031 and the second jaw 1032 move toward one another under gravity are until closing, thus complete a grasping movement.Again before subjob, lift the first pull bar 1051 and the second pull bar 1052, in order to make the first jaw 1031 of grab bucket 103 and the second jaw 1032 open.
Grab bucket-type dredger 10 according to this utility model embodiment is by arranging fixed pulley 102 and arranging movable pulley 104 in grab bucket 103 on first connecting rod 101, thus when the benthon in the lakebed matter of river is sampled, have only to upwards lift grip part 106, just grab bucket 103 can be driven to move up by movable pulley 104, in order to complete to sample work.Thus grab bucket-type dredger 10 is convenient to operate, and sampling efficiency is high.
Being additionally, since rope 107 and walk around fixed pulley 102 and movable pulley 104, therefore when being sampled the benthon in the lakebed matter of river, rope 107 will not rub with the miscellaneous part of grab bucket-type dredger 10.Thus it is possible not only to the hand avoiding the rope 107 of abrasion to scratch operator, and is possible to prevent rope 107 to rupture, in order to improve the service life of grab bucket-type dredger 10.
Additionally, the quantity of rope 107 can also be reduced according to the grab bucket-type dredger 10 of this utility model embodiment.
Therefore.Grab bucket-type dredger 10 according to this utility model embodiment have convenient to operate, sampling efficiency is high, length in service life, safety advantages of higher.
As shown in Figure 1-Figure 3, first connecting rod 101, fixed pulley 102, grab bucket 103, movable pulley the 104, first pull bar the 1051, second pull bar 1052, grip part 106, rope 107 and unhook 108 are included according to the grab bucket-type dredger 10 of embodiments more of the present utility model.
Grab bucket 103 includes body 1033 and second connecting rod 1034.Body 1033 has the first jaw 1031 and the second jaw 1032, and the first jaw 1031 is connected with the second jaw 1032 pivotly by pivotal axis.Second connecting rod 1034 is located on pivotal axis, and movable pulley 104 is located on second connecting rod 1034.By the second connecting rod 1034 that is connected with this pivotal axis of setting, and movable pulley 104 is located on second connecting rod 1034, such that it is able to more easily, be easily installed movable pulley 104.
As shown in Figure 1-Figure 3, in an embodiment of the present utility model, first connecting rod 101 and second connecting rod 1034 are arranged vertically, and first connecting rod 101, second connecting rod 1034, movable pulley 104 and fixed pulley 102 are positioned on same vertical curve.The structure that thus can make grab bucket-type dredger 10 is more reasonable.
In an example of the present utility model, as shown in Figure 1-Figure 3, the bottom of the first jaw 1031 is provided with the first lug 1035, the bottom of the second jaw 1032 is provided with the second lug 1036, the lower end of the first pull bar 1051 is connected with the first lug 1035 pivotly, and the lower end of the second pull bar 1052 is connected with the second lug 1036 pivotly.By arranging the first lug 1035 and the second lug 1036, such that it is able to make the first pull bar 1051 be connected more easily, easily with the first jaw 1031 and the second jaw 1032 with the second pull bar 1052.
As in figure 2 it is shown, at least one in the first jaw 1031 and the second jaw 1032 is provided with osculum 1037.The water in sample thus can be made can to discharge grab bucket 103 by osculum 1037.
Advantageously, equal at the maximum position being manually opened, the first jaw 1031 and the upper angle of the second jaw 1032 formation and lower angle.Wherein, at the maximum position being manually opened, the first jaw 1031 and the second jaw 1032 are generally in level.
As depicted in figs. 1 and 2, in examples more of the present utility model, grip part 106 includes third connecting rod 1061 and the suspension ring 1062 being located on the upper end of third connecting rod 1061, and the first end of rope 107 is connected with third connecting rod 1061.When utilizing grab bucket-type dredger 10 to be sampled the benthon in the lakebed matter of river, operator hold with a hand suspension ring 1062, such that it is able to make grab bucket-type dredger 10 easily facilitate operation.
And, by arranging third connecting rod 1061, such that it is able to make rope 107 be connected with grip part 106 more easily.Advantageously, rope 107 is steel wire rope.
As shown in figures 1 and 3, unhook 108 is rotatably arranged on grip part 106, and unhook 108 is hooked on first connecting rod 101 separatably.When grab bucket-type dredger 10 enters after water bottoms out, breaking off relations 108 departs from first connecting rod 101 under gravity.Before the grab bucket-type dredger 10 according to this utility model embodiment enters water, the first jaw 1031 and the second jaw 1032 open, and upset unhook 108 hooks are connected on first connecting rod 101.
Grab bucket-type dredger 10 according to this utility model embodiment utilizes movable pulley 104 to replace the Slipper of crank block, movable pulley 104 vertically moves under the effect with gravity of the pulling force upwards, thus the part between fixed pulley 102 and movable pulley 104 of rope 107 instead of post portion.Applying pulling force upwards, movable pulley 104 moves upward, and the first jaw 1031 and the second jaw 1032 move toward one another are until closing.
Grab bucket-type dredger 10 easily operation directly perceived according to this utility model embodiment, can improve and adopt mud efficiency, and design simple, with low cost, decreases steel wire rope quantity.
