DETAILED DESCRIPTION
[0017] The utility model will be further described below in conjunction with the accompanying drawings.
[0018] like Figures 1 to 4The illustrated embodiment of a grass rake that is easy to turn comprises a frame 1, wherein both ends of the frame 1 are fixedly connected with universal wheels 6 through first support rods 3, and both ends of the frame 1 are also rotatably connected with turntables 5 through second support rods 4, and the two turntables 5 are arranged with relative inclinations, wherein a hydraulic motor 7 is fixedly connected to one of the second support rods 4, and the output end of the hydraulic motor 7 is fixedly connected to the turntable 5 to provide power for the rotation of the turntable 5, and a cross bar 11 is hinged between the turntables 5, and a plurality of grass rake teeth 12 are fixedly connected to the end of the cross bar 11, and a fixed frame 8 is fixedly connected to the center of the top end of the frame 1, and the fixed frame 8 is fixedly connected to the frame 1. A shaft is connected, a shaft sleeve is provided on the shaft, a connecting rod 9 is fixedly connected to the shaft sleeve, a telescopic cylinder 13 is hinged between the connecting rod 9 and the side of the frame 1, the other end of the connecting rod 9 is hinged to the bracket 2 by means of a pin shaft, a sliding sleeve 14 is fixedly connected to the top of the bracket 2, a sliding rod is slidably arranged in the sliding sleeve 14, a triangular plate 10 is fixedly connected to one end of the sliding rod, the triangular plate 10 is a hollow structure, a positioning shaft 901 is fixedly connected to the top of the connecting rod 9, the positioning shaft 901 is located in the triangular plate 10, a fixing rod 16 is fixedly connected to the front end of the bracket 2, and hinge seats 15 are fixedly connected to both ends of the fixing rod 16.
[0019] In order to facilitate the adjustment of the position of the triangular plate 10 , the other end of the slide rod of the triangular plate 10 is fixedly connected to a hinge support, and semicircular grooves are provided at the three corners of the triangular plate 10 to cooperate with the positioning pin 901 to clamp the triangular plate 10 .
[0020] In order to conveniently control the tilt direction of the grass rake, a telescopic cylinder 13 is hinged between the frame 1 and the connecting rod 9. The telescopic cylinder 13 is one of a pneumatic telescopic cylinder, a hydraulic telescopic cylinder, and an electric telescopic cylinder. In this embodiment, a hydraulic telescopic cylinder is used.
[0021] In order to prevent the machine body from swaying left and right during the turning process, one of the universal wheels 6 is controlled by a connecting rod mechanism, and the driving direction is always consistent with the driving direction of the grass mower.
[0022] The connecting rod mechanism includes a first connecting rod 17, one end of the first connecting rod 17 is fixedly connected to the shaft sleeve, and the other end is hinged to the second connecting rod 18, the other end of the second connecting rod 18 is hinged to the third connecting rod 19, the other end of the third connecting rod 19 is fixedly connected to the upper end of the vertical rod 20, the lower end of the vertical rod 20 is fixedly connected to the fourth connecting rod 21, the other end of the fourth connecting rod 21 is hinged to the basket bolt 22, and the other end of the basket bolt 22 is hinged to the main shaft of the universal wheel 6. In this way, when turning, the direction of one of the universal wheels 6 can be controlled by the connecting rod mechanism to always keep consistent with the direction of travel of the fuselage, thereby preventing the problem of being unable to maintain stable steering when the locating pin 901 is at the bottom edge of the triangular plate 10, and the problem of the fuselage swinging left and right at will.
[0023] The working process of this embodiment is as follows:
[0024] The hinge seat 15 and the hinge support are connected to the suspension of the tractor, and then the hydraulic motor 7 is turned on. When the tractor is transporting the grass rake, the hinge support is pulled to make the sliding rod drive the triangular plate 10 to move, so that the positioning pin 901 is stuck at the top of the triangular plate 10, so that the grass rake will not move left and right at will to ensure stability during transportation. When it is necessary to carry out grass rake work, the hinge support is pushed to make the sliding rod drive the triangular plate 10 to move, so that the positioning pin 901 is at the bottom edge of the triangular plate 10. In this way, when the tractor rotates, the positioning pin 901 moves at the bottom edge of the triangular plate 10, and will not limit the rotation between the connecting rod 9 and the bracket 2, so that the grass rake can achieve a slow rotation effect with the tractor to ensure the grass rake effect. The hydraulic motor 7 drives the turntable 5 to rotate, and then drives the cross bar 11 and the grass rake teeth 12 to move. The grass rake teeth 12 repeat the movement to achieve the purpose of raking grass. The telescopic cylinder 13 is responsible for adjusting the angle between the grass rake and the tractor so as to adjust it to the best working state.
