Abstract
The utility model relates to a hanging device for a plough share and a seeder which are arranged on a hand tractor. The hanging device for a plough share and a seeder which are arranged on a hand tractor is characterized in that a hanging head 1 and a hanging frame 8 are hinged by a shaft pin; a connecting ear 2 is welded on the hanging head 1; one end of a screw rod 4 is welded with a shaft pin 3 which is hinged with the connecting ear 2; a connecting frame 7 is welded on the hanging frame 8; the screw rod can penetrate through a hole arranged on the connecting frame and is fixed by screw nuts 5, 6. The effective length of the adjusting screw rod can make the hanging frame occur upward and downward displacement to obtain the purpose of the regulation of the tillage depth. The utility model has the advantages of simple structure, low cost, convenient operation, etc.
Description
The utility model relates to a kind of farm machinery, and particularly a kind of hand tractor is cultivated the hanging device of usefulness.
Original hand tractor is cultivated the hanging device of usefulness, mainly is made up of hanging joint and hitching frame, and they are made as one through welding.When reality is used, exist and to regulate the defective of cultivating the degree of depth.Find that by retrieval some can solve this defective as hydraulic drive, the powerdriven adjustable hanging device of hand tractor.Obviously, these technical schemes exist complex structure, use shortcomings such as inconvenience, cost height.
The purpose of this utility model is exactly a kind of hanging device that governor motion is arranged that designs at the shortcoming of prior art existence.
To achieve these goals, the utility model has adopted following technical proposals:
Hanging joint and hitching frame are with pivot pin hinged (be welded with on the hanging joint to connect be welded with groove shape on ear, the hitching frame and connect ear, their are hinged with pivot pin); A hinged screw rod on the hanging joint (be welded with the U type on the hanging joint and connect ear, screw rod one end welding pivot pin is articulated in the U type and connects in the ear), affixed on the hitching frame (as welding) hitch, the hole that screw rod passes on the hitch is locked them with nut.In addition, a pair of cotter pin hole is set, increases the interface of the connecting frame on hanging joint and the tractor, to reduce the abrasion deformation of the pin-and-hole on the connecting frame in the symmetric position of the kingpin hole of hanging joint.
By technique scheme as can be seen, hitching frame, screw rod can rotate relative to hanging joint, and the position of adjusting screw(rod) and hitch (being the length of adjusting screw(rod)) just can make liter or decline on the hitching frame rear end.Therefore, it has advantages such as simple in structure, with low cost, easy to use.
For the utility model is described in further detail, following routine accompanying drawing provides a most preferred embodiment of the present utility model.
Description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
(rear end of hitching frame 8 is provided with farm implements such as plough or sower as shown in Figure 1, save among Fig. 1, Fig. 2), hanging joint 1 and hitching frame 8 are prior art parts, the a pair of connection ear 11 of welding on hanging joint 1, a pair of connection ear 10 is welded in the left part of hitching frame 8, and pivot pin 9 passes the hole that articulates in the ear 10,11 hanging joint 1 and hitching frame 8 are hinged together.The U type that welds at the middle part of hanging joint 1 connects ear 2, and an end of screw rod 4 welds a pivot pin 3, and it passes the hole that connects in the ear 2 makes it hinged.Welding one hitch 7 on hitching frame 8, screw rod 4 can pass the hole in the hitch 7, and with nut 5,6 with screw rod and hitch and fasten.As can be seen from Figure 2, the position of adjusting screw(rod) and hitch can make the right-hand member (connecting plough or sower etc.) of hitching frame 8 produce upper and lower displacement, shown in the direction of arrow among the figure.When ploughing, use kingpin hole 13 to connect, can make the pin-and-hole abrasion deformation of connecting frame after the time is permanent with the tractor connecting frame.Therefore the kingpin hole symmetric position at hanging joint is provided with a pair of cotter pin hole 12,14, can when ploughing or sow, adopt different connection combinations to reduce abrasion deformation like this, as can adopt when ploughing kingpin hole or kingpin hole to add two cotter pin holes to connect, can adopt kingpin hole or two cotter pin holes to connect during sowing.
Claims (2)
1, hand tractor hanging device, it comprises hanging joint and hitching frame, it is characterized in that hanging joint and hitching frame are hinged with pivot pin, hanging joint is in addition with the hinged screw rod of pivot pin, an affixed hitch on the hitching frame, screw rod can pass the hole on the hitch, with a pair of nut on the screw rod screw rod and hitch is fixed.
