Abstract
The utility model discloses a camshaft quick lifter which comprises a left support plate and a right support plate. Two sides of an upper end of the left support plate and the right support plate are respectively connected into an organic whole through a connecting plate. Installing holes are respectively arranged on the connecting plate. The middle part of the upper end of the right support plate is provided with a fixed shaft. Driving chain wheels are shiftly installed on the fixed shaft through shaft sleeves. Driving hand shanks are installed on the shaft sleeves. A revolving shaft is installed between the left support plate and the right support plate of the lower end portion. Driven chain wheels are installed on the protrusion end of the revolving shaft. The driven chain wheels and the driving chain wheels are connected through chains. Two paratactic camshafts are fixedly installed in the middle part of the revolving shaft. Corresponding installing holes are respectively arranged on the camshafts. Pin rolls are coordinately installed through the installing holes. Shaft sleeves of the front end portion of arc-shaped plates are shiftly installed in the middle part of the pin rolls. Installing plates are arranged on the back end of the arc-shaped plates. Grooves coordinate with a tail pulley base rod are arranged on the middle part of the back end face of the installing plates. The camshaft quick lifter is economical to use. Reliability, safety, stability and durability of the complete machine working are improved. Tail pulleys are quickly lifted instantly and have a self locking function. The cost of the complete machine is low.
Description
Technical field
The utility model relates to agricultural mechanical field, relates in particular to a kind of cam damping quick lifting device.
Background technology
Before not improving the cam damping quick lifting device, tractor and agricultural equipment such as combine one are by mechanical elevating, substitute with the manual rocking bar of tail wheel, lifting time is long, beat easily in the work, regulate lifting time is 40 seconds at every turn, about 360 yuan of elevating mechanism totle drilling cost.The 2nd, adopt the hydraulic way lifting, lifting time is 20 seconds, mainly is that cost is high, and every is overlapped 400 yuan, mainly is that oil sealing damages soon, and maintenance is inconvenient.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of cam damping quick lifting device is provided, its reasonable in design, it is long to have solved the mechanical elevating time, beat easily in the work, to regulate lifting time long at every turn, and cost is high when adopting the hydraulic way lifting, the problems such as oil sealing damages fast, and maintenance is inconvenient.
The utility model is achieved through the following technical solutions:
A kind of cam damping quick lifting device, include a left side, right supported plate, it is characterized in that: a described left side, the both sides of the upper end of right supported plate connect as one by connecting plate respectively, be distributed with respectively installing hole on the described connecting plate, the middle part of described right supported plate upper end is provided with fixed axis, be rotatablely equipped with drive sprocket by axle sleeve on the described fixed axis, and driving handle is installed on the axle sleeve, the left side of bottom, be rotatablely equipped with rotating shaft between the right supported plate, the right-hand member of described rotating shaft stretches out right supported plate, and external part is equipped with driven sprocket, be connected by chain between described driven sprocket and the drive sprocket, the middle part of described rotating shaft is installed with two cams arranged side by side, be respectively equipped with corresponding installing hole on the described cam, and by cooperating in the installing hole bearing pin be installed, described bearing pin middle part is rotatablely equipped with the axle sleeve of arc leading section, described arc rear end is provided with installing plate, and described installing plate is provided with installing hole.
Described connecting plate is bolted respectively at the fixed head of the forebay crossbeam of hand tractor and seat support bar and is installed as one.
Described two cams are fixedly installed in a side of rotating shaft side by side, and its bottom is welded as a whole with rotating shaft respectively, and its leading section is provided with respectively corresponding installing hole.
Described axle sleeve is round sleeve, and described round sleeve is fixedly mounted on the leading section of arc, and is the integral type structure.
The rear end face middle part of described installing plate is provided with the groove that cooperates with the tail wheel base bar, is respectively equipped with installing hole on the installing plate of described groove both sides.
Its principle is: cam lift is in addition retrofit on tail wheel lifting and hydraulic lifting basis, and its technical merit one is to embody in the innovation: adopt the function of the modes such as hydraulic pressure fast more than 5 times on the rising or falling speed, and can be at 4 seconds kind fast liftings; The 2nd, be embodied on the advanced person: adopt cam to promote curved sliding surface, drive arc and rotate 45 degree, make tail wheel moment fast lifting and have auto-lock function.The 3rd, be embodied on economic the use: not only improve reliability, safety, stability and the durability of complete machine work, and the complete machine cost descends 240 yuan than hydraulic lifting.
The utility model has the advantages that:
The utility model reasonable in design, adopt the function of the modes such as hydraulic pressure fast more than 5 times on the rising or falling speed, make simultaneously tail wheel moment fast lifting and have auto-lock function, the economic use, not only improved reliability, safety, stability and the durability of complete machine work, and the complete machine cost is low.
