Description

Technical Field

[0001] This utility model relates to the field of rice transplanter technology, specifically a high-strength, heavy-duty rice transplanter frame. Background Technology

[0002] A rice transplanter is an agricultural machine used to plant rice seedlings into paddy fields. During planting, a mechanical claw first removes several rice seedlings from a seedbed and plants them into the soil. To maintain a right angle between the seedbed and the ground, the front end of the claw must move in an elliptical curve. The movement is accomplished by a planetary mechanism using rotary or variable gears, while a forward engine drives these moving parts. The transplanter must have non-slip wheels and a floating design to move on the soil. If planting in rows, seedlings are taken from specific seed boxes and planted mechanically.

[0003] In the current production of rice transplanters, the frame structure is connected by butt joints and welding of the pole ends. This butt joint welding can cause cracks and breakage at the welding points, affecting the overall load-bearing capacity of the frame. On the other hand, when the frame is fixed in one piece, the frame structure is too bulky and inconvenient to transport and use. Utility Model Content

A reinforcing crossbar is horizontally fixedly connected between the middle joint blocks. A reinforcing inner lining layer is fixedly provided on the inner sides of the main outer connecting rod and the reinforcing crossbar. A through groove is horizontally formed on the inner sides of the main outer connecting rod and the reinforcing crossbar, and the inner side of the through groove is horizontally fixed. The device is equipped with a reinforcing plug rod, which has symmetrical fixed docking holes on its side. The corner docking block has a reinforced inner layer fixedly installed on its inner side. The corner docking block has end insertion grooves at both ends. The middle docking block has a reinforcing inner layer fixedly installed on its inner side. The middle docking block has symmetrical stabilizing slots at both ends. The middle docking block has symmetrical mating holes on its side.

The extension side block has a connecting slot at its end away from the middle docking block. The extension side block has symmetrical through holes on its side.

[0007] In a preferred embodiment of this utility model: there are multiple main external connecting rods, and the dimensions of the multiple main external connecting rods are not the same, and the materials of the multiple main external connecting rods are all the same. There are multiple corner joint blocks, and the multiple corner joint blocks are arranged in a right-angled L-shape, and the corner joint blocks are all located at the corners of the frame.

[0008] In a preferred embodiment of this utility model, there are multiple intermediate connecting blocks, and the specifications and dimensions of the multiple intermediate connecting blocks are all set to be consistent. One end of multiple main external connecting rods is horizontally connected and set at the two open ends of the stable slot. There are two auxiliary connecting blocks, and the two auxiliary connecting blocks are arranged in the opposite direction to the intermediate connecting blocks.

[0009] In a preferred embodiment of this utility model, the side through holes are all opened through the sides of the corner joint block near both ends, and the side through holes extend into the interior of the end insertion groove to maintain communication. The fixing screws are all inserted into the inner sides of the side through holes, mating holes and through holes, and the extension ends are inserted into the inner sides of the fixing mating holes.

[0010] In a preferred embodiment of this utility model: the material and specifications of the reinforcing crossbar are consistent with those of the main external connecting rod. The reinforcing crossbars are arranged on the inner side of the frame body. The through slot is horizontally opened at the inner center line of the main external connecting rod and the reinforcing crossbar, and both ends of the through slot are open. The reinforcing insert is horizontally inserted into the inner side of the through slot, and the two extended ends are correspondingly inserted into the inner side of the end insertion slot, the stabilizing slot and the connecting slot.

[0011] In a preferred embodiment of this utility model: the fixed docking holes are symmetrically and through-holes located on the side of the reinforcing rod near both ends; the stabilizing slot and the mating hole are connected to each other; the middle docking block and the extension side block are arranged in a T-shape; and the connecting slot and the through hole are connected to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention integrates multiple main external connecting rods with reinforcing inserts extending from both ends, which are then inserted into the end insertion slots 1. The fixing screws are correspondingly inserted into the side through holes and fixing docking holes, forming a fixed connection. This creates a corner-like connection between the multiple main external connecting rods. For horizontal fixing of the main external connecting rods, a middle docking block can be installed at the middle end to fix two horizontally arranged main external connecting rods together. During the connection, both ends are wrapped for fixation, effectively preventing misalignment and cracks at the connection point, thus increasing the strength of the connection. After being fixedly connected to the periphery of multiple main external connecting rods, an external frame effect is formed. The reinforcing crossbar in the middle position is inserted into the internal connecting slots at both ends and fixed by fixing screws to form a reinforced connection inside the frame. The high-strength steel material of the reinforced inner lining, reinforced inner layer and solid inner layer makes the connection and installation position more secure, improving the overall load-bearing capacity of the frame. The modular structure makes it small in size after disassembly, which is convenient for transportation and use. At the same time, the splicing installation structure eliminates the need for welding during installation, improving installation efficiency. The combination of multiple reinforcing connection structures greatly improves the overall strength. Attached Figure Description
