Abstract
The invention aims at providing a trenching device of a small-sized loader, which mainly consists of a drill bit, a connection pin, an output shaft, a bearing cover, a mounting plate, a rack welding member, a speed reducer, a land welding member, a small drive shaft, a hydraulic motor control valve and a bearing, and is structurally characterized in that a hydraulic motor is connected with the land welding member and connected with the speed reducer through the small drive shaft and then mounted on the rack welding member; the drill bit below is connected with the output shaft by a spline, and the connection pin penetrates through the middle to prevent the drill bit from falling off; the output shaft bearing cover is mounted and connected with the mounting plate and then firmly connected with the rack welding member through the mounting plate.
Description
Technical field
The invention belongs to agricultural mechanical field, be specifically related to a kind of pit digging apparatus for small-sized loading machine.
Background technology
At present, be used for afforestation in China, in the hole digger field of the hole operations such as staking out, tradition type is all to drive digging apparatus with the four-wheel tractor of power output after band, but along with country's agricultural, the rapid expansion of Forestry Area, with four-wheel tractor drive hole digger there are a lot of defects, inefficiency, maneuverability is poor, can not meet a lot of gardens industry users' actual demand far away, for this reason, we have designed a kind of with the hydraulic pump driving digging apparatus on loading machine, this device has compact conformation, function admirable, operating efficiency is high, easy to operate, possess the maneuverability of height, can meet the demand of the little job space of user, not only for user saves a large amount of manpower and materials, also for they have saved a large amount of funds, very popular with users, its market prospects are very considerable.
Summary of the invention
The object of the invention is to provide a kind of machinery that drives digging apparatus with the hydraulic pump on loading machine, it is mainly made up of drill bit, connecting pin, output shaft, bearing cap, installing plate, frame welding part, reductor, terminal pad soldering member, little driving shaft, hydraulic motor, bearing, its following structural features: hydraulic motor is connected on terminal pad soldering member, connect reductor by little driving shaft, then be arranged on frame welding part, below drill bit and output shaft spline joint, connecting pin is put in centre, in case drill bit comes off; Install bearing cap, be connected on installing plate, then bearing cap is connected firmly by installing plate and frame welding part.
Its work is to realize like this, thereby opening control valve makes hydraulic motor rotation drive reductor, reductor drives bit, the position that the flexible centering of the oil cylinder that adjustment connects with rocking arm is digged pit, the pressure-relief valve of opening loading machine makes swing arm free-falling, drill bit starts to dig pit, and after digging pit, promotes swing arm, continues next action.
The present invention has adopted said structure, optimizes, simplified digging apparatus, can be widely used in the operation of gardens, and the flexible property of this type compact structure, easily operation and height, can better meet the little job space of user, improves operating efficiency; Not only, for user saves a large amount of manpower and materials, also, for they have saved a large amount of funds, market prospects are very good.
Accompanying drawing explanation
Fig. 1 is invention assembling schematic diagram.
Fig. 2 is invention assembling schematic diagram A-A cutaway view.
Embodiment
Below in conjunction with accompanying drawing 1, accompanying drawing 2, digging apparatus embodiment of the present invention is further described: hydraulic motor (14) is connected on terminal pad soldering member (12), connect reductor (11) by little driving shaft (13), bearing cap (8) end of speed reducer output shaft (7) has been installed and has been born axial force bearing (15), connecting pin (6) has been fixed on drill bit (5) and output shaft (7), so just entirety forms a pit digging apparatus for small-sized loading machine (1), then by installing plate (9), pit digging apparatus for small-sized loading machine (1) is fixed on frame welding part (10).
In the time of work, open that control valve makes hydraulic motor (14) thus rotation drives reductor (11), reductor (11) drives drill bit (5) rotation, the position that the flexible centering of the oil cylinder (4) that adjustment connects with rocking arm (3) is digged pit, the pressure-relief valve of opening loading machine makes swing arm (2) free-falling, drill bit starts to dig pit, and after digging pit, promotes swing arm, continues next action.
Claims (1)
1. a pit digging apparatus for small-sized loading machine, by drill bit, connecting pin, output shaft, bearing cap, installing plate, frame welding part, reductor, terminal pad soldering member, little driving shaft, hydraulic motor control valve, bearing composition, it is characterized in that: hydraulic motor is connected on terminal pad soldering member, connect reductor by little driving shaft, then be arranged on frame welding part, below drill bit and output shaft spline joint, connecting pin is put in centre, in case drill bit comes off, install bearing cap, be connected on installing plate, again bearing cap is connected firmly by installing plate and frame welding part.
