Abstract
The utility model discloses a novel tractor maximum lifting force test connection device. The test connection device comprises a leading screw. The leading screw is sleeved with a positioning nut matching the leading screw and used for limiting a lifting height. A connection sleeve sleeving the leading screw and connected with a lifting frame of a tractor is arranged under the positioning nut. The bottom of the leading screw is connected with a tension sensor used for detecting the lifting force of the tractor. The connection sleeve is composed of two semicircles. One end of the connection sleeve is in hinged connection and the other end of the connection sleeve is fixed tightly through a bolt. A hooking hole integrated with the connection sleeve is arranged in the connection sleeve. The lifting frame is connected with the hooking hole. A rubber sleeve preventing the leading screw from damage is arranged on the inner wall of the connection sleeve. The test connection device adjusts the lifting height through the position of the positioning nut in the leading screw to meet the experiment requirements. The test connection device has advantages of simple structure, low cost, convenient usage and the like.
Description
Technical field
The utility model has related to a kind of Novel tractor feed pull maximum test connecting device.
Background technology
Standard " GB/T3871.4-2006 agricultural traction engine testing regulations the 4th part: rearmounted three-link hitch load-carrying capacity " regulation: in the time measuring lifting force, should measure at least 6 some places of substantially equal spacing in whole expanded reach.The adjusting of current 6 hoisting depth points has two kinds of common modes, and a kind of is to determine position by hydraulic jack flexible, and this regulative mode need to be set up Hydraulic Station, and cost is higher, is not suitable for applying at medium-sized and small enterprises.Another kind of mode is to offer multiple lifting holes at lifting arm, realizes determining of different hoisting depths, although this regulative mode cost is lower, 6 points of point locations are not accurate enough, and require great effort in the time changing connecting hole.
Summary of the invention
The purpose of this utility model is to design a kind of Novel tractor feed pull maximum test connecting device, to carry out easily the test of tractor feed pull maximum.
The technical solution adopted in the utility model is as follows:
A kind of Novel tractor feed pull maximum test connecting device, comprises a leading screw; On described leading screw, being set with one is mated and for hoisting depth is carried out to spacing setscrew nut, below setscrew nut, be provided with one and be sleeved on the adapter sleeve being connected on leading screw and with the lift frame of tractor, be connected with a pulling force sensor for detection of tractor lifting force in the bottom of leading screw.
Described adapter sleeve is made up of two halves circle, and its one end is articulated and connected, and the other end, by bolted, is provided with the mount hole being integrated with it on adapter sleeve, and described lift frame is connected on mount hole.
Described adapter sleeve inwall is provided with and prevents rubber sleeve that leading screw is destroyed.
In described leading screw short transverse, be provided with uniformly respectively 6 lifting force check points, for detection of tractor feed pull maximum.
The course of work of the present utility model is as follows:
In the time carrying out 6 hoisting depth point feed pull maximum tests of tractor, the lift frame of tractor is connected with adapter sleeve, then setscrew nut is installed on leading screw, and adjust to the position of first lifting force check point, adapter sleeve is placed in the lower end of setscrew nut, lift frame is implemented to pulling force upwards, and pulling force sensor shows the size of pulling force; Next, running fix nut is to 5 remaining check points successively, and adapter sleeve moves successively with setscrew nut, detects the lifting force at each check point place.
The beneficial effects of the utility model are as follows:
The utility model by setscrew nut the position at leading screw, regulate hoisting depth, meet requirement of experiment;
2. the inwall of adapter sleeve is provided with rubber sleeve, prevents the destruction of adapter sleeve to leading screw.
3. the utlity model has the features such as simple in structure, with low cost, easy to use, only realized the test to tractor feed pull maximum by leading screw, setscrew nut, three devices of adapter sleeve.
Brief description of the drawings
Fig. 1 is connection diagram of the present utility model;
Fig. 2 is the utility model connecting jacket structure schematic diagram;
In figure 1, leading screw; 2, setscrew nut; 3, adapter sleeve.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further
As Figure 1-Figure 2, a kind of Novel tractor feed pull maximum test connecting device comprises leading screw 1, setscrew nut 2, adapter sleeve 3.Carrying out feed pull maximum when test, be fixed on desired location by setscrew nut 2 and carry out spacingly, adapter sleeve 3 is positioned at setscrew nut 2 lower ends and is connected with lift frame, the lower end connection pulling force sensor of leading screw 1.
While carrying out 6 hoisting depth point feed pull maximum tests, the position by setting nut at leading screw, regulates hoisting depth, meets requirement of experiment.
Adapter sleeve is articulated and connected by two semicircular part one end, and the other end passes through bolted.While needs, after bolt unclamps, adapter sleeve is opened, can take off from leading screw.
The inwall of adapter sleeve is provided with rubber sleeve, prevents the destruction of adapter sleeve to leading screw.
