Agricultural machinery is a variety of mechanical equipment used in agricultural production, aiming to improve agricultural production efficiency, reduce farmers' labor intensity, and improve the agricultural production environment. Some shield support frames are used on the couplings of agricultural machinery, which are mainly used to protect the couplings of agricultural machinery from damage by external objects, extend their service life, and ensure the smooth progress of agricultural production.

[0003] However, the existing shield support frame has the following disadvantages: since the shield support frame of the agricultural machinery coupling is usually put on the outside of the coupling from top to bottom, it may be restricted by some other mechanical parts, resulting in a smaller space above the coupling, making it inconvenient to install the shield support frame to the outside of the coupling. Therefore, the existing shield support frame needs to be improved. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6 The utility model provides the following technical solutions: a shield support frame with a limited docking structure, comprising a No. 1 cover body 1 and a heat dissipation net 5, a No. 2 cover body 2 is arranged on one side of the No. 1 cover body 1, a No. 2 cover body 2 is fixed on one end of the No. 1 cover body 1 and the No. 2 cover body 2, a connecting plate 3 is fixed on one end of the No. 1 cover body 1 and the No. 2 cover body 2, a mounting bolt 4 is penetrated through the internal thread of the connecting plate 3, the heat dissipation net 5 is arranged on the side where the No. 1 cover body 1 and the No. 2 cover body 2 are away from each other, a No. 1 docking mechanism 6 is arranged on the side adjacent to the No. 1 cover body 1 and the No. 2 cover body 2, an anti-collision plate 10 is connected to the outer side of the No. 1 cover body 1 and the No. 2 cover body 2 near the heat dissipation net 5 through a buffer mechanism 7, a No. 2 docking mechanism 9 is arranged above the No. 1 cover body 1 and the No. 2 cover body 2, and a No. 1 pull rod 8 is connected to one side of the No. 1 docking mechanism 6.

[0025] according to Figure 1-3 and Figure 5-6As shown, the No. 1 docking mechanism 6 includes a docking rod 601, a docking groove 602, a positioning block 603, a return spring 604 and a No. 1 slide bar 605. The No. 1 cover body 1 is provided with a docking rod 601 on one side close to the No. 2 cover body 2, and a docking groove 602 is provided on one side close to the docking rod 601 of the No. 2 cover body 2. A No. 1 slide bar 605 is installed in a built-in groove of the No. 2 cover body 2 close to the docking groove 602. The outer side of the No. 1 slide bar 605 is slidably sleeved with a positioning block 603, and the middle part of the No. 1 slide bar 605 is sleeved with a return spring 604. 4. One end of the positioning block 603 close to the outer side of the second cover body 2 is connected to the first pull rod 8. The second docking mechanism 9 includes a supporting spring 901, a second pull rod 902, a limiting block 903 and a limiting groove 904. A supporting spring 901 is provided in the built-in groove above the first cover body 1. A limiting block 903 is provided on one side of the supporting spring 901. A limiting groove 904 is provided on one side of the second cover body 2 close to the limiting block 903. The cross-sectional shape of the positioning block 603 is "L"-shaped, and the cross-sectional shape of the limiting block 903 is arc-shaped.

[0026] In specific implementation, the shield support frame may be restricted by some other mechanical parts during installation, resulting in a smaller space above the coupling, making it inconvenient to install the shield support frame to the outside of the coupling. When installing the shield support frame to the outside of the coupling, you can first pull the No. 2 pull rod 902 to one side to dock the No. 1 cover body 1 and the No. 2 cover body 2, and insert the docking rod 601 into the docking groove 602, and then pull the No. 1 pull rod 8 to drive the No. 1 pull rod 8 to drive the positioning block 603 to slide closer to each other on the No. 1 slide bar 605 and squeeze the reset spring 604. When the No. 1 pull rod 8 is pulled, the positioning block 603 can slide closer to each other on the No. 1 slide bar 605 and squeeze the reset spring 604. After the connecting rod 601 completely enters the docking groove 602, the No. 1 pull rod 8 is loosened, so that the return spring 604 rebounds and drives the positioning block 603 to move away from each other and insert into the socket on one side of the docking rod 601, thereby limiting the position of the docking rod 601. Then, the No. 2 pull rod 902 is loosened, so that the support spring 901 rebounds and drives the limit block 903 to insert into the limit groove 904, thereby docking the tops of the No. 1 cover body 1 and the No. 2 cover body 2. The No. 1 docking mechanism 6 and the No. 2 docking mechanism 9 can enable the No. 1 cover body 1 and the No. 2 cover body 2 to be quickly docked, thereby improving the convenience of installation of the shield support frame.

[0027] according to Figure 1-4 As shown, the buffer mechanism 7 includes a slider 701, a buffer rod 702, a second slider 703 and a buffer spring 704. The second slider 703 is installed in the outer reserved groove of the No. 1 cover body 1 and the No. 2 cover body 2 close to the heat dissipation net 5. The outer side of the No. 2 slider 703 is sleeved with a slider 701 and a buffer spring 704. One side of the slider 701 is connected to the buffer rod 702 through a movable shaft, and one end of the buffer rod 702 is connected to the anti-collision plate 10 through a movable shaft. The number of the anti-collision plates 10 is two, and the number of the buffer mechanism 7 is four.

[0028] During specific implementation, since heat dissipation nets 5 are provided on both sides of the coupling guard support frame on the agricultural machinery, but the heat dissipation nets 5 are relatively thin and cannot withstand the impact of objects, when an object hits the guard heat dissipation net 5, it will first impact the anti-collision plate 10, and then the anti-collision plate 10 squeezes the buffer rod 702, causing the buffer rod 702 to squeeze the slider 701, and drive the slider 701 to slide to one side on the second slider 703, and the slider 701 will squeeze the buffer spring 704, and then the buffer spring 704 rebounds to cause the slider 701 to drive the buffer rod 702 to return to its original position, which can reduce the impact force of the object on the anti-collision plate 10. By setting the anti-collision plate 10, it can prevent the object from directly colliding with the heat dissipation net 5 and causing damage to the heat dissipation net 5, which is beneficial to extending the service life of the guard support frame.

[0029] The working principle of the shield support frame with a limited docking structure described in the utility model is as follows: first, the No. 1 shield body 1 and the No. 2 shield body 2 are placed on the outside of the agricultural machinery coupling, and then the No. 1 shield body 1 and the No. 2 shield body 2 are limitedly docked through the No. 1 docking mechanism 6 and the No. 2 docking mechanism 9, and then the No. 1 shield body 1 and the No. 2 shield body 2 are installed on the body of the agricultural machinery through the installation bolts 4. When an object collides with the heat dissipation net 5 of the shield support frame, the impact force can be buffered by the buffer mechanism 7 and the anti-collision plate 10, thereby improving the installation convenience of the shield support frame and extending the service life of the shield support frame.
