The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Referring to fig. 1, the agricultural machinery placing rack comprises a base 1, wherein an upright post 2 is fixedly connected to the left side of the base 1, the upright post 2 is connected with a lifting table 6 in a sliding manner, a limiting block 10 is fixedly connected to the top of the upright post 2, and the limiting block 10 can prevent the lifting table 6 from rising until the lifting table 6 is separated from the upright post 2 when a machine control component fails, so that danger is caused; 6 lower parts of elevating platform are equipped with first spout 7, and 7 sliding connection sliders 8 of first spout, the articulated bracing piece 4 of base 1, the articulated slider 8 of bracing piece 4 other end, the articulated cylinder 5 in 1 right side of base, the articulated bracing piece 4 of 5 piston rods of cylinder.
Referring to fig. 2, the left side of the base 1 is hinged with a pull rod 3, the other end of the pull rod 3 is hinged with a rotating table 18, one end of the rotating table 18 is fixedly connected with a fixed seat 14, the middle part of the fixed seat 14 is fixedly connected with a nut 13, the nut 13 is in threaded connection with a screw rod 12, the end part of the screw rod 12 is fixedly connected with a handle 11, and the handle 11 can increase the rotating radius, so that an operator can rotate the screw rod 12 with small force; the other end of the rotating table 18 is fixedly connected with a fixed clamping plate 19, a second sliding groove 17 is formed in the middle of the rotating table 18, the second sliding groove 17 is connected with a sliding clamping plate 15 in a sliding mode, a shock absorption pad 9 is arranged on the upper portion of the lifting table 6, when the rotating table 18 rotates anticlockwise, the shock absorption pad 9 can effectively prevent the rotating table 18 and the lifting table 6 from being rigidly impacted, and the danger that the agricultural machine 22 breaks down due to impact is avoided; the articulated revolving stage 18 in elevating platform 6 tip, slip grip block 15 and fixed grip block 19 inboard all are equipped with flexible liner 16, centre gripping agricultural machine 22 in the middle of the flexible liner 16, flexible liner 16 can effectually prevent grip block and agricultural machine 22 rigid contact to avoid appearing because the centre gripping leads to the appearance problems such as agricultural machine 22 surface painting fish tail.
Referring to fig. 3, the second embodiment is improved on the basis of the first embodiment, the upright post 2 is fixedly connected with the handrail 20, and the handrail 20 can better control the direction of the invention and push the invention; the bottom of the base 1 is fixedly connected with a caster 21, the fixed clamping plate 15 can be directly pushed into a gap between the agricultural machine 22 and the bottom of the ground through the caster 21, the agricultural machine 22 can be directly placed into a placing rack with a fixed height from the ground without carrying for the second time by operating the agricultural machine-supporting device like a forklift.
In the invention, in the using process, firstly, a piston rod of an air cylinder 5 is contracted to drive a supporting rod 4 to rotate clockwise, a lifting platform 6 is enabled to slide downwards through a sliding block 8 hinged with the end part of the supporting rod 4, a pull rod 3 pushes a rotating platform 18 to rotate clockwise in the downward sliding process of the lifting platform 6, when a fixed clamping plate 19 is flush with the ground, the air cylinder 5 stops working to push the invention, the fixed clamping plate 19 is pushed into a gap between an agricultural machine 22 and the ground, a handle 11 is rotated to drive a screw rod 12 to rotate, the screw rod 12 pushes a sliding clamping plate 15 to move downwards, the sliding clamping plate 15 and the fixed clamping plate 19 clamp the agricultural machine 22, at the moment, the air cylinder 5 is driven reversely, the piston rod of the air cylinder 5 stretches out, the piston rod pushes the supporting rod 4 to rotate anticlockwise, so that the lifting platform 6 is pushed to move upwards through the sliding block 8, and the, the rotating platform 18 rotates anticlockwise, when the rotating platform 18 contacts the shock pad 9, the air cylinder 5 stops working, the agricultural machinery is pushed to a storage position, and the operation is finished; according to the agricultural machine fixing device, the actions of clamping and lifting the height of the agricultural machine 22 are completed through the combined action of the air cylinder 5 and the connecting rod, the agricultural machine 22 directly reaches the position to be placed from the ground without manual carrying, the purpose of fixing and placing large-scale agricultural machines is achieved, manpower and time are greatly saved, the operation is simple and convenient, and the agricultural machine fixing device is suitable for popularization and use.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
