Description

Technical Field

[0001] This utility model relates to the field of wheat planter technology, specifically a wheat planter with a fixed-point guiding mechanism. Background Technology

[0002] A wheat seeder is an agricultural machine used in conjunction with a tractor. It is suitable for row sowing of crops such as wheat and oats in plains and hilly areas, and can also be used for furrow fertilization. Its core functions include multiple operations such as furrowing, sowing, fertilization and covering with soil, and the sowing depth and sowing rate can be adjusted according to needs.

[0003] The patent document, published under CN223110506U and entitled "A Wheat Sowing Point Guiding Device," describes a device that uses a sliding groove and a sliding seat to install sowing tubes on a horizontal plate. The sliding seat can slide within the groove. This structure allows for flexible adjustment of the distance between sowing tubes according to the needs of the planting site. By controlling the sowing spacing, it enables point-guided sowing of wheat seeds, ensuring a reasonable spatial distribution during wheat growth and guaranteeing the absorption of sunlight, water, and nutrients by the plants.

[0004] The horizontal plate has multiple screw holes on one side that connect to the sliding groove. When adjusting the spacing between the seeding tubes according to planting needs, the operator slides the slide block in the sliding groove of the horizontal plate. After adjusting to the appropriate position, the operator tightens the fastening bolts in the screw holes to make the fastening bolts press against the slide block, thereby fixing the position of the seeding tube. However, in order to make the spacing between the seeding tubes more adjustable and meet the needs of more sites, the screw holes need to be set closely. However, the existing technology only sets one row of screw holes. If the screw holes are set closely, the distance between adjacent screw holes will be too small, which will cause the horizontal plate structure between adjacent screw holes to be too small. As a result, the horizontal plate structure with too small a distance between adjacent screw holes is prone to deformation due to stress after long-term use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a wheat planter with a fixed-point guiding mechanism, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a wheat seeder with a fixed-point guiding mechanism, including a connecting frame connected to a traction device, the connecting frame being connected to a machine frame, and the machine frame being provided with a wheat bin, wheels, a soil covering roller, and a fixing component;

[0007] The fixing assembly includes two fixing plates, both of which are connected to the frame. The fixing plates are evenly provided with screw holes one and screw holes two, and the screw holes one and screw holes two are staggered.

[0008] The tops of the two fixed plates are evenly attached to a connecting component, and the connecting component includes a connecting rod that contacts both fixed plates. Both ends of the connecting rod are provided with telescopic devices. The telescopic devices are connected to a connecting block with a connecting hole. The connecting block is provided with a bolt that connects to the connecting hole. The bolt matches both screw hole one and screw hole two.

[0009] The connecting rod is connected to a furrowing shovel, and the furrowing shovel is connected to a seeding pipe. The seeding pipe is connected to the wheat bin via a telescopic flexible hose.

[0010] Preferably, the telescopic device includes an electric telescopic rod, one end of which is provided with a first insert block, and the other end of which is provided with a second insert block.

[0011] Preferably, the connecting rod has a through groove, and the electric telescopic rod and the connecting block are both located in the through groove. A slide rail is provided in the through groove, and the connecting block is slidably connected in the slide rail.

[0012] Preferably, the connecting block has a slot, a protrusion, and a plug is inserted into the slot and in contact with the protrusion. A bolt connects the plug and the protrusion.

[0013] Preferably, the connecting rod has a slot 2 that communicates with the through groove, the connecting rod has a protruding plate 2, the insert block 2 is inserted into the slot 2 and contacts the protruding plate 2, and a bolt 3 connects the insert block 2 and the protruding plate 2.

[0014] Preferably, both sides of the fixed plate are provided with sliding grooves, and the two ends of the connecting rod are slidably connected to the sliding grooves on both sides respectively.

[0015] This invention provides a wheat seeder with a fixed-point guiding mechanism. Compared with the prior art, it has the following advantages:

[0016] 1. This wheat seeder with a fixed-point guiding mechanism has rows of staggered screw holes 1 and 2 on the fixed plate. Then, the connecting block is moved by the telescopic device on the connecting rod, so that the connecting block can be connected to screw hole 1 or screw hole 2 through the connecting hole and bolt 1. This makes the spacing between adjacent connecting rods more adjustable, so that the spacing between adjacent furrowing shovels and seeding tubes can meet the needs of more sites, and does not require the screw holes to be set tightly. This ensures that the spacing between adjacent screw hole 1 or adjacent screw hole 2 is not too small, thus avoiding the problem of deformation of the screw holes due to stress after long-term use of the fixed plate.

[0017] 2. The wheat seeder with a fixed-point guiding mechanism is equipped with slot one, slot two, convex plate one, convex plate two, bolt two and bolt three, which facilitates the disassembly and assembly of the telescopic device. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4 This utility model provides the following two technical solutions:

[0025] First embodiment: A wheat seeder with a fixed-point guiding mechanism includes a connecting frame 100 connected to a traction device, the connecting frame 100 being connected to a frame 200, and the frame 200 being provided with a wheat bin 300, wheels 400, a soil covering roller 500, and a fixing component 600.

[0026] The fixing assembly 600 includes two fixing plates 601 that are both connected to the frame 200. The fixing plates 601 are evenly provided with screw holes 602 and screw holes 603, and the screw holes 602 and screw holes 603 are staggered. This ensures that the screw holes are evenly distributed so as to have more spacing adjustment possibilities, and also avoids that the spacing between adjacent screw holes 602 or adjacent screw holes 603 is too small, thus ensuring the structural strength of the fixing plate 601 around the screw holes 602 and screw holes 603.

[0027] The tops of the two fixed plates 601 are evenly attached to the connecting components 700, and the connecting components 700 include connecting rods 701 that are in contact with both fixed plates 601. Both ends of the connecting rods 701 are provided with telescopic devices 702. The telescopic devices 702 are connected to the connecting blocks 703 with connecting holes 704. The connecting blocks 703 are provided with bolts 705 that are connected to the connecting holes 704. Bolts 705 are matched with screw holes 602 and 603. The telescopic devices 702 drive the connecting blocks 703 to move, so that the connecting holes 704 can be aligned with screw holes 602 or 603, and can be connected by bolts 705.

[0028] A furrowing shovel 800 is connected to the connecting rod 701, and a seeding tube 900 is connected to the furrowing shovel 800. The seeding tube 900 is connected to the wheat bin 300 through a telescopic hose. When the connecting rod 701 moves, both the furrowing shovel 800 and the seeding tube 900 move. The furrowing shovel 800 opens furrows, the seeding tube 900 pours wheat seeds into the furrows, and the covering roller 500 completes the covering.

[0029] The telescopic device includes an electric telescopic rod 7021, one end of which is provided with a first insertion block 7022, and the other end of which is provided with a second insertion block 7023. The electric telescopic rod 7021 is powered and controlled by existing technology.

[0030] The connecting rod 701 has a through groove 706, and the electric telescopic rod 7021 and the connecting block 703 are both located in the through groove 706. The through groove 706 has a slide rail 707, and the connecting block 703 is slidably connected in the slide rail 707, which can improve the stability of the connecting block 703 when it moves.

[0031] The connecting block 703 has a slot 708 and a protrusion 709. The insert 7022 is inserted into the slot 708 and contacts the protrusion 709. A bolt 7010 connects the insert 7022 and the protrusion 709, so that the insert 7022 can be inserted into or removed from the slot 708.

[0032] The connecting rod 701 has a slot 7011 that communicates with the through groove 706. The connecting rod 701 has a protrusion 7012. The insert 7023 is inserted into the slot 7011 and contacts the protrusion 7012. The insert 7023 and the protrusion 7012 are connected by a bolt 7013, so that the insert 7023 can be removed from the slot 7011, thereby allowing the electric telescopic rod 7021 to be taken out from the through groove 706.

[0033] The second embodiment differs from the first embodiment in that: both sides of the fixing plate 601 are provided with sliding grooves 604, and both ends of the connecting rod 701 are slidably connected to the sliding grooves 604 on both sides, which can guide the movement of the connecting rod 701.

[0034] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0035] In use, the movable connecting rod 701 is aligned with the desired screw hole 602 or screw hole 603. Then, the movable connecting block 703 is aligned with the desired screw hole 602 or screw hole 603 via the telescopic device 702. Subsequently, the bolt 705 is inserted into the connecting hole 704 to fix it with the screw hole 602 or screw hole 603, thereby ensuring that the spacing between adjacent connecting rods 701 has more adjustment possibilities.
