Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery, and agricultural transportation machinery, etc.

[0003] The patent document with publication number "CN221718274U" discloses a roof-mounted heating device for agricultural machinery cab, including a support plate for installation in the cab, a bracket on the top of the support plate, and a symmetrical mounting structure on the outer wall of the bracket.

[0004] Although the aforementioned patent documents have solved the problems of energy waste caused by using electric heating air and the inability to utilize the energy generated by the engine, the following drawbacks still exist: the heating structure is fixed to the mounting structure by bolts and fixing blocks, and each of the four corner bolts needs to be tightened one by one during disassembly and assembly, which is cumbersome and inconvenient, resulting in low disassembly and assembly efficiency and is not conducive to the use of the device. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the prior art: the heating structure is fixed to the fixing block by the bolts of the installation structure. When disassembling and assembling, it is necessary to tighten the four corner bolts one by one, which is cumbersome and inconvenient, resulting in low disassembly and assembly efficiency and is not conducive to the use of the device. The proposed agricultural machinery cab roof heating device is to address these shortcomings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The agricultural machinery cab has a roof-mounted heating device, which includes a bracket, a heating structure and a duct. Two T-shaped mounting blocks are fixedly connected to both sides of the heating structure, and two U-shaped plates are fixedly connected to both sides of the bracket. Each T-shaped mounting block has a slot at one end that passes through the corresponding U-shaped plate. A fixing block is fixedly connected to one side of the bracket, and a reciprocating screw is rotatably connected to the fixing block. A concave plate is threaded onto the reciprocating screw, and a limiting component is provided on the concave plate. The limiting component includes two concave strips fixedly connected to the concave plate, and each concave strip engages with two corresponding slots. A hollow cylinder is fixedly connected to one end of the reciprocating screw, and a sliding component is provided on the hollow cylinder.

[0007] Preferably, a fixing rod is fixedly connected to one side of the bracket, and the concave plate and the fixing rod are slidably connected.

[0008] Preferably, the sliding assembly includes a slide rod fixedly installed inside the hollow cylinder, a rectangular rod slidably sleeved on the outer side of the slide rod, a circular plate fixedly connected to one end of the rectangular rod, and a plurality of locking blocks fixedly connected to one side surface of the circular plate, with a circular groove for connecting the locking blocks on the fixing block.

[0009] Preferably, a groove is provided on one inner wall of the hollow cylinder, and an L-shaped strip is slidably connected in the groove. The L-shaped strip is connected to the rectangular rod through a hinge rod, and a sliding opening is provided on the hollow cylinder for the L-shaped strip to move back and forth.

[0010] Preferably, the outer surface of the hollow cylinder is provided with an arc-shaped groove, the inner wall of the arc-shaped groove is fixedly connected with a magnet, an arc-shaped iron strip is slidably connected in the arc-shaped groove, and the L-shaped strip is provided with a slot for connecting the arc-shaped iron strip.

[0011] Preferably, each of the T-shaped mounting blocks is fixedly connected to a limiting ring, and the surface of each limiting ring is in contact with the upper surface of the corresponding U-shaped plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The mechanical transmission that drives the concave strip to engage or disengage from the slot via a reciprocating screw replaces the traditional method of tightening bolts one by one. Multiple sets of T-shaped mounting blocks can be locked or released simultaneously simply by rotating the hollow cylinder, greatly shortening the disassembly and assembly time, significantly improving operation and maintenance efficiency, and benefiting the use of the device. 2. The limiting ring achieves axial positioning, the concave strip achieves radial locking, and the locking block and the circular groove cooperate to limit the screw from turning incorrectly. The multi-dimensional locking structure ensures that the heating structure is stable and reliable after installation and can adapt to the vibration environment of agricultural machinery operation. The cooperation between the sliding component and the limiting component makes operation without additional tools. A single person can complete the disassembly and assembly, reducing the skill requirements of the operator and meeting the needs of rapid operation and maintenance of agricultural machinery on site.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0017] Reference Figures 1-5 The agricultural machinery cab has a roof-mounted heating system, including a bracket 2, a heating structure 1, and a duct 3. Two T-shaped mounting blocks 6 are fixedly connected to both sides of the heating structure 1. Two U-shaped plates 7 are fixedly connected to both sides of the bracket 2. Each T-shaped mounting block 6 has a slot at one end of the corresponding U-shaped plate 7. A fixing block 5 is fixedly connected to one side of the bracket 2. A reciprocating screw 10 is rotatably connected to the fixing block 5. A concave plate 8 is threaded onto the reciprocating screw 10. A limit component is provided on the concave plate 8. The limit component includes two concave strips 15 fixedly connected to the concave plate 8. Each concave strip 15 engages with the two corresponding slots. When the concave strip 15 engages with the corresponding slot, it can radially lock the T-shaped mounting block 6. A hollow cylinder 11 is fixedly connected to one end of the reciprocating screw 10. A sliding component is provided on the hollow cylinder 11.

[0018] A fixed rod 9 is fixedly connected to one side of the bracket 2. The concave plate 8 and the fixed rod 9 are slidably connected. The fixed rod 9 provides guidance for the movement of the concave plate 8 and prevents the concave plate 8 from rotating with the reciprocating screw 10. The sliding assembly includes a slide rod 14 fixedly installed inside the hollow cylinder 11. A rectangular rod 13 is slidably sleeved on the outside of the slide rod 14. A circular plate 4 is fixedly connected to one end of the rectangular rod 13. A plurality of locking blocks 12 are fixedly connected to one side surface of the circular plate 4. A circular groove for connecting the locking blocks 12 is opened on the fixed block 5.

[0019] A groove is provided on one inner wall of the hollow cylinder 11, and an L-shaped strip 18 is slidably connected in the groove. The L-shaped strip 18 is connected to a rectangular rod 13 via a hinge rod 17. The two ends of the hinge rod 17 are respectively hinged to the L-shaped strip 18 and the rectangular rod 13. A sliding opening is provided on the hollow cylinder 11 for the L-shaped strip 18 to move back and forth. An arc-shaped groove is provided on the outer surface of the hollow cylinder 11. A magnet is fixedly connected to the inner wall of the arc-shaped groove. An arc-shaped iron strip 19 is slidably connected in the arc-shaped groove. The position of the L-shaped strip 18 can be limited by the magnetic attraction force. A bayonet is provided on the L-shaped strip 18 for connecting the arc-shaped iron strip 19.

[0020] Each T-shaped mounting block 6 is fixedly connected to a limiting ring 16. The surface of each limiting ring 16 is in contact with the upper surface of the corresponding spiral plate 7. The T-shaped mounting block 6 can penetrate the spiral plate 7, and the surface of the limiting ring 16 is in contact with the upper surface of the spiral plate 7, so as to achieve the initial axial positioning of the T-shaped mounting block 6 and prevent it from excessive displacement after insertion.

[0021] In this invention, the T-shaped mounting blocks 6 on both sides of the heating structure 1 are aligned with the U-shaped plate 7 on the bracket 2 and inserted downwards until the limiting ring 16 on the T-shaped mounting block 6 is in contact with the upper surface of the U-shaped plate 7, thus completing the initial axial positioning of the T-shaped mounting block 6. Then, the hollow cylinder 11 is rotated, which drives the reciprocating screw 10 to rotate. Since the concave plate 8 and the fixed rod 9 are slidably connected to restrict the rotation, the reciprocating screw 10 will drive the concave plate 8 to slide along the fixed rod 9 when it rotates, until the two concave strips 15 on the concave plate 8 are respectively engaged with the slots at the ends of each T-shaped mounting block 6, thus achieving radial locking of the T-shaped mounting block 6, that is, it cannot be dislodged from the U-shaped plate 7.

[0022] Then, push the circular plate 4, causing the rectangular rod 13 to slide along the slide bar 14. The rectangular rod 13 pushes the L-shaped strip 18 along the slide groove through the hinge rod 17 until the locking block 12 on the circular plate 4 is inserted into the circular groove of the fixing block 5, which can limit the reciprocating screw 10 from turning incorrectly. At this time, one end of the L-shaped strip 18 passes through the slide opening. Then slide the arc-shaped iron strip 19 along the arc groove, so that one end of it is locked into the locking opening of the L-shaped strip 18. Use the magnetic attraction force to fix the L-shaped strip 18, thereby locking the position of the rectangular rod 13 and the circular plate 4, so that the warm air structure 1 and the bracket 2 are firmly connected together. Similarly, the disassembly operation can also be carried out quickly.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to fixed connection, detachable connection, or integral connection; they can refer to mechanical connection or electrical connection; they can refer to direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
