Description

Technical Field

[0001] This utility model belongs to the field of heat insulation cover technology, specifically relating to a multi-purpose heat insulation cover for agricultural machinery. Background Technology

[0002] Agricultural machinery refers to the general term for mechanical equipment used in agricultural production and related agricultural activities such as primary processing of agricultural products. It includes various power and operational machinery such as harvesters, tractors, and sprayers. During the busy summer farming season, when temperatures are high, agricultural machinery stops operating at midday to allow personnel to rest and for the machines to cool down. However, the midday sun is at its strongest, shining directly on the machinery, which not only affects cooling but also shortens the machine's lifespan due to sun exposure. Therefore, heat shields are needed to cover the machinery. However, in current technology, these heat shields generally require a support frame that needs to be inserted into the ground for fixation. This makes it difficult to adjust quickly and is not suitable for agricultural machinery of different sizes. Furthermore, driving the machinery under the heat shield requires caution to prevent collisions, so the speed needs to be slow, which is inconvenient. Utility Model Content

A heat insulation cloth cover 18 is wound around the outer side of the drum 17. One end of the heat insulation cloth cover 18 is connected to a crossbar 19. A hook connecting groove 20 is provided through the crossbar 19. A hook 21 is installed on the top of the first telescopic rod 26 of the fixed end telescopic support rod 1.

[0034] This device has folding and unfolding functions, as well as adjustable lateral width and longitudinal length. It can be quickly deployed and retrieved, and is easy to transport and move. It is suitable for midday sun protection and heat insulation of agricultural machinery of different sizes. In use, it can be quickly extended and folded through the cooperation of the telescopic support rod 2, universal wheels 7, and telescopic scissor mechanism 10, so that agricultural machinery can be driven away quickly.

[0035] An anchor bolt insertion hole 5 is provided between the top and bottom of the anchor bolt connecting plate 4, and an anchor bolt 6 is inserted into the inner side of the anchor bolt insertion hole 5.

[0036] Anchor bolt 6 is used to fix the fixed end telescopic support rod 1 to the ground.

[0037] The first telescopic outer rod 25 of the set of movable end telescopic support rods 2, which is equipped with the second pin seat 12, has a limiting slide 22 slidably installed on its side, and a limiting screw 23 is installed through the side of the limiting slide 22.

[0038] When the adjusting slide rod 15 and the drum 17 are folded to the side of the device, the sliding limit slide 22 is slid to pass between the adjusting slide rod 15 and the drum 17. Then the limit screw 23 is installed on the limit slide 22 and tightened, so that the adjusting slide rod 15 and the limit slide 22 limit each other, thereby fixing the adjusting slide rod 15.

[0039] A crank handle 24 is mounted through and rotatably on the drum mounting base 16, and one end of the crank handle 24 is connected to the drum 17.

[0040] Turning the crank handle 24 will drive the drum 17 to rotate and wind up the heat insulation cloth cover 18.

[0041] The first telescopic rod 26 of the fixed end telescopic support rod 1 and the movable end telescopic support rod 2 are provided with a first pin seat 8 on one side. Folding telescopic connecting rods 9 are pinned between the first pin seats 8 of the two sets of fixed end telescopic support rods 1 and between the first pin seats 8 of the two sets of movable end telescopic support rods 2.

[0042] The folding telescopic connecting rod 9 enhances the structural strength of the device and enables the two sets of movable telescopic support rods 2 to move synchronously.

[0043] The folding telescopic connecting rod 9 includes two sets of second telescopic outer rods 27 and two sets of second telescopic rods 28. The second telescopic outer rods 27 and the second telescopic rods 28 are inserted and connected to each other. The two sets of second telescopic outer rods 27 are rotatably connected to a set of first pin seats 8 respectively. The two sets of second telescopic rods 28 are rotatably connected to each other.

[0044] A folding telescopic connecting rod 9, consisting of a second telescopic outer sleeve rod 27 and a second telescopic rod 28, is provided between the two sets of fixed-end telescopic support rods 1 and between the two sets of movable-end telescopic support rods 2. While enhancing the structural strength of the device, it can also adapt to the changes in the distance between the fixed-end telescopic support rods 1 and the distance between the movable-end telescopic support rods 2 by adjusting the telescopic extension and rotation accordingly.

[0045] Both the first telescopic outer sleeve rod 25 and the second telescopic outer sleeve rod 27 have through screw holes on their sides and are threadedly connected to locking screws 3.

[0046] After the extension and retraction adjustment of the first telescopic rod 26 and the second telescopic rod 28 is completed, tighten the locking screw 3 to lock the first telescopic outer rod 25 and the first telescopic rod 26, as well as the second telescopic outer rod 27 and the second telescopic rod 28.

[0047] The working principle and usage process of this utility model are as follows: When using this device, firstly, adjust the distance between the two sets of fixed-end telescopic support rods 1 and the distance between the two sets of movable-end telescopic support rods 2 according to the width of the agricultural machinery to be protected. Since the fixed-end telescopic support rods 1 and the movable-end telescopic support rods 2 are connected by a telescopic scissor mechanism 10, the distance between the two sets of fixed-end telescopic support rods 1 and the distance between the two sets of movable-end telescopic support rods 2 can be adjusted synchronously. After adjustment, use anchor rods 6 to insert into anchor rod holes 5 and insert them into the ground to fix the fixed-end telescopic support rods 1. Then, unscrew the limiting screw 23 and slide the limiting slide block 22 to release the limitation on the adjusting slide rod 15. Then, raise the adjusting slide rod 15 and move it inside the sliding sleeve 14. Slide the sliding rod 15 so that one end can be limited and supported by the support bracket 11. At the same time, adjust the center position of the sliding rod 15 to be almost aligned with the center of the distance between the two sets of movable telescopic support rods 2. Then pull the crossbar 19 to connect the hook connecting groove 20 on the crossbar 19 with the hook 21. Then adjust the extension length of the first telescopic rod 26 according to the height of the agricultural machinery, thereby adjusting the height of the sliding rod 15. After the adjustment is completed, tighten the locking screw 3 on the side of the first telescopic outer rod 25. When it is necessary to provide sunshade and heat insulation for the agricultural machinery, drive the agricultural machinery to the rear of this device so that the middle position of the agricultural machinery is almost aligned with the middle position of the distance between the two sets of fixed telescopic support rods 1. Then, pull the movable telescopic support rod 2 to move it through the universal wheel 7. A folding telescopic connecting rod 9, consisting of a second telescopic outer sleeve rod 27 and a second telescopic rod 28, is provided between the two sets of fixed-end telescopic support rods 1 and between the two sets of movable-end telescopic support rods 2. This serves to enhance the structural strength of the device and allows for adaptive extension, contraction, and rotation adjustment as the distance between the fixed-end telescopic support rods 1 and the movable-end telescopic support rods 2 changes. After adjustment, the locking screw 3 on the side of the second telescopic outer sleeve rod 27 is tightened for fixation. The folding telescopic connecting rod 9 also allows the two sets of movable-end telescopic support rods 2 to move synchronously. As the movable-end telescopic support rods 2 move, the roll 17 automatically unwinds under the pulling action of the hook 21 on the hook connecting groove 20, allowing the heat insulation cover 18 to... Once released, the moving telescopic support rod 2's travel distance is determined by the length of the agricultural machinery. As the moving telescopic support rod 2 passes the rear end of the agricultural machinery, the heat insulation cover 18 provides comprehensive coverage of the machinery, offering excellent heat insulation and sun protection. With the movement of the moving telescopic support rod 2, the telescopic scissor mechanism 10 automatically extends and retracts, maintaining the connection between the fixed telescopic support rod 1 and the moving telescopic support rod 2, thus preserving the overall structural strength of the device. When the agricultural machinery needs to be used, simply push the moving telescopic support rod 2 back to its original position to drive the machinery away easily. After use, remove the anchor rod 6, and the device can be folded back up. Loosen the locking screws 3 on the sides of the first telescopic outer sleeve rod 25 and the second telescopic outer sleeve rod 27.The first telescopic rod 26 can be retracted into the first telescopic outer rod 25, and the folding telescopic connecting rod 9 can be folded to bring the two sets of fixed-end telescopic support rods 1 and the two sets of movable-end telescopic support rods 2 closer together. After disconnecting the hook connecting groove 20 and the hook 21, the roller 17 can be rotated by the crank 24 to roll up the heat insulation cloth cover 18. Then, the adjusting slide rod 15 is slid and the rotating shaft 13 is rotated to make the adjusting slide rod 15 return to the side of the movable-end telescopic support rod 2 for folding. Then, the sliding limit slide 22 limits the adjusting slide rod 15 and the limit screw 23 is tightened. To prevent the limiting slide 22 from resetting, it should be kept in the limiting position on the adjusting slide 15. After completing the above operations, the folding of this device is complete, facilitating movement and handling. In summary, this device has folding and unfolding functions, as well as lateral width and longitudinal length adjustment functions. It allows for rapid deployment and retrieval, facilitating movement and handling. It is suitable for midday sun protection and heat insulation of agricultural machinery of different sizes. Furthermore, during use, it can be quickly extended and folded through the cooperation of the telescopic support rod 2, universal wheels 7, and telescopic scissor mechanism 10, allowing for rapid departure of agricultural machinery.
