Embodiment 1

[0033] Such as Figure 1~4 As shown, a kind of downhole floating debris cleaning grass catcher includes a disc 2, a tray 8, a grass catcher rod 1, a first inner tube 7, a tray tensioning line 5 and 5 mechanical claws, and the diameter of the tray 8 is Less than the diameter of the disc 2; the grass catcher rod 1 is an inner hollow structure, the lower end of the grass catcher rod 1 is fixed at the center of the disc 2, and the center of the disc 2 is provided with a hole, so One end of the first inner tube 7 passes through the hole and enters the inside of the grass catcher rod 1 and is connected with one end of the pallet tensioning wire 5, and the other end of the first inner tube 7 is fixed on the tray 8 In the center, the other end of the pallet tensioning wire 5 protrudes from the grass catcher rod 1 .

[0034] The mechanical claw includes a probing leg 3, a probing leg cross arm 6 and a probing tongue 4, the top of each probing leg 3 is evenly distributed along the circ...

Embodiment 2

[0040] The difference between this embodiment and embodiment 1 is: as Figure 7 As shown, the downhole floating debris cleaning grass catcher also includes a squeezing device, and the squeezing device includes a pressure plate 12, a pressure plate tension line 13 and a second inner pipe 11, and the pressure plate 12 is selected to have a density much higher than that of water. A solid disc such as an iron disc, the outer diameter of the second inner tube 11 is smaller than the inner diameter of the first inner tube 7, the center of the tray 8 is provided with a central hole corresponding to the second inner tube 11, the The radius of the pressure plate 12 is smaller than the radius of the disc 2; one end of the second inner tube 11 passes through the central hole and extends into the first inner tube 7 and an end of the pressure plate tension wire 13 connected, the other end of the second inner tube 11 is fixed at the center of the pressure plate 12, and the other end of the p...

Embodiment 3

[0043] The difference between this embodiment and embodiment 1 is: as Figure 5 As shown, the tray 8 is provided with a slide groove 15 corresponding to one end of each leg probe arm 6, and the extension direction of each slide groove 15 is consistent with the stroke direction of the leg probe arm 6. One end of the arm 6 falls into the corresponding sliding groove 15 and can move back and forth along the sliding groove 15 . Combined with the structure of the guide plate, the instability of the single-point limit of the guide plate is avoided, and the movement range of the detection leg is further ensured to be in a stable plane through the two-point limit.

Abstract

The invention provides an underground floater cleaning grass fisher. The grass fisher comprises a disc, a tray, a grass fisher rod, a first inner tube, a tray tightening wire and multiple mechanical grabbers, each mechanical grabber comprises a detecting leg, a detecting leg cross arm and a detecting tongue, one end of each detecting leg cross arm is caught on the tray and faces the center of thetray, the other end of each detecting leg cross arm is fixed to the upper end of the corresponding detecting leg and hinged to the edge of the disc together with the detecting leg, the included angleof each detection leg cross arm and the corresponding detecting leg is smaller than 90 degrees, each detecting tongue is installed at the lower end of the corresponding detecting leg through a rotating shaft, the free end of each detecting tongue faces the axis of the disc and can rotate around the rotating shaft to reach the horizontal position to the lowest. The grass fisher is low in cost, lowin weight, easy to operate and convenient to use, and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of weed fishing equipment, and relates to a weed fishing device for cleaning floating objects in wells. Background technique [0002] At present, my country's arable land area is 1.8 billion mu, and there are about 18 million wells distributed in the rural wilderness. Among them, about 1 / 10 of the wells are blocked by floating objects such as straw and weeds, seriously affecting the normal use of the wells. Existing weed catchers for water wells have disadvantages such as complex structure, heavy weight, and inconvenient operation, and most of the fields have complex topography, making it difficult for equipment to enter. Therefore, the downhole floating debris cleaning weed catcher with low development cost, light weight, simple operation and convenient use has broad application prospects. Contents of the invention [0003] The object of the present invention is to aim at the deficiencies of the prior art, thereb...
