Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a corn and peanut composite trenching planter. Background Technology

[0002] In agricultural production, corn and peanuts are important food and cash crops, and ditching is a crucial step in their planting process, directly affecting the sowing depth, growing environment, and subsequent field management efficiency. Currently, various ditching planting equipment is available on the market for corn and peanut cultivation. These devices typically use a frame as the basic carrier, combined with functional components such as soil loosening and ditching, to achieve mechanized planting operations. The aim is to replace traditional manual ditching methods, improve planting efficiency, and reduce the labor intensity for farmers.

[0003] Among the existing trenching planting equipment, some equipment only has a single trenching function. When facing planting areas with hard soil texture or compaction, due to the lack of effective soil loosening pretreatment, the trenching components have to withstand greater resistance to complete the trench excavation. This not only easily leads to increased wear and tear on the trenching components and increased energy consumption, but may also result in uneven trench depth and irregular trench walls, affecting the consistency of subsequent seed sowing. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a corn and peanut combined trenching planter, which solves the problems of insufficient soil loosening and poor trenching quality in existing corn and peanut trenching planting equipment.

[0005] To achieve the above objectives, this utility model provides a corn and peanut composite trenching planter, including a bracket. A soil loosening device and a trenching device are arranged sequentially from front to back along the working direction on the bracket. The soil loosening device is used to loosen the soil surface. The trenching device includes a connecting shaft and several bidirectional augers rotatably mounted on the connecting shaft. The multiple bidirectional augers are arranged at equal intervals. The bidirectional augers are used to push the loose soil to both sides to form a trench.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Preferably, the trenching device also includes two connecting seats symmetrically arranged in the horizontal direction perpendicular to the working direction. The connecting seats are detachably installed on the bracket by bolts. Each of the two connecting seats has a mounting groove for fitting and installing a connecting shaft on the side that is close to each other. The two ends of the connecting shaft extend into the mounting grooves of the two connecting seats respectively.

[0008] Preferably, the bidirectional auger has an internally fixed mounting sleeve, the inner wall of the mounting sleeve is fixedly provided with a sliding key, the connecting shaft is provided with a keyway that slides with the sliding key, and the mounting sleeve is provided with fixing screws for fixing the mounting sleeve to the connecting shaft.

[0009] Preferably, the soil loosening device includes a power shaft mounted on a bracket, with a number of rotary tillage blades evenly spaced along its axial direction on the power shaft, and a drive motor on one side of the bracket for driving the power shaft to rotate.

[0010] Preferably, a drive gear is fixedly mounted on the power shaft, and a transmission gear that meshes with the drive gear is fixedly mounted on the connecting shaft.

[0011] Preferably, a leveling plate is provided at the rear end of the bracket along the working direction. The leveling plate is raised and lowered on the bracket and is used to level the soil surface after trenching.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By sequentially installing a soil loosening device and a ditching device on the bracket, the soil texture becomes loose after loosening, which can reduce the resistance of the two-way auger ditching, reduce component wear, and at the same time ensure uniform ditch depth and regular ditch walls, thereby improving planting quality. The bidirectional auger slides along the connecting shaft through the cooperation of a sliding key and a keyway, and is locked in place by fixing screws. The spacing can be quickly adjusted to adapt to the planting row spacing requirements of different varieties of corn and peanuts. It is simple to operate and does not require disassembly of a large number of parts. Attached Figure Description

[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. 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.

[0016] Please see Figures 1-4 As shown, this embodiment provides a corn and peanut combined trenching planter. The corn and peanut combined trenching planter includes a bracket 1, which serves as the basic load-bearing structure of the equipment, used to install various functional components and ensure overall stability. A soil loosening device 2 and a trenching device 3 are sequentially arranged on the bracket 1 from front to back along the working direction, forming a "loosening the soil first, then trenching" work process to ensure that the soil is sufficiently loosened before trenching.

[0017] The soil loosening device 2 is used to loosen the surface soil of the planting area, preventing the soil from being too hard during trenching, which could cause wear on components or irregular trenches. The soil loosening device 2 includes a power shaft 201 fixed on a bracket 1. Several rotary tillage blades 202 are evenly spaced along the axial direction of the power shaft 201. When the rotary tillage blades 202 rotate with the power shaft 201, they can cut and break up the soil, achieving surface soil loosening. A drive motor 203 is provided on one side of the bracket 1, which provides rotational power to the power shaft 201 to ensure the loosening effect.

[0018] In summary, the improvement of this embodiment is that the rotary tillage blade 202 can cut and break the soil when it rotates with the power shaft 201, thereby loosening the surface soil.

[0019] Based on the above, other structures also need to be disclosed in detail, such as: The trenching device 3 includes a connecting shaft 301 and several bidirectional augers 302 rotatably mounted on the connecting shaft 301. The bidirectional augers 302 are evenly spaced and are used to push the loose soil to both sides to form the trenches required for planting. Their symmetrical spiral structure ensures that the soil is evenly piled on both sides of the trench and that the trench walls are flat. The trenching device 3 also includes two connecting seats 303 symmetrically arranged in a horizontal direction perpendicular to the working direction. The connecting seats 303 are detachably mounted on the bracket 1 by bolts for easy disassembly and maintenance. Each of the two connecting seats 303 has a mounting groove 310 on one side close to each other for fitting the connecting shaft 301. Both ends of the connecting shaft 301 extend into the mounting grooves 310 of the two connecting seats 303, and the mounting grooves 310 provide rotational support for the connecting shaft 301 to ensure its rotational stability.

[0020] An installation sleeve 304 is fixedly inserted inside the bidirectional auger 302, and the installation sleeve 304 rotates synchronously with the bidirectional auger 302. A sliding key 305 is fixedly provided on the inner wall of the installation sleeve 304, and a keyway 306 is provided on the connecting shaft 301 to slide with the sliding key 305. The cooperation between the sliding key 305 and the keyway 306 allows the bidirectional auger 302 to slide along the axial direction of the connecting shaft 301, which facilitates the adjustment of the spacing between adjacent bidirectional augers 302 to adapt to the planting row spacing requirements of different crops. The installation sleeve 304 is provided with a fixing screw 307 for fixing the installation sleeve 304 to the connecting shaft 301. After the spacing is adjusted, the position of the bidirectional auger 302 can be locked by tightening the fixing screw 307 to prevent displacement during operation.

[0021] A drive gear 308 is fixedly installed on the power shaft 201, and a transmission gear 309 that meshes with the drive gear 308 is fixedly installed on the connecting shaft 301. The gear meshing transmission can transmit the rotational power of the power shaft 201 to the connecting shaft 301, ensuring the power synchronization between the loosening device 2 and the trenching device 3, reducing transmission loss, and improving power efficiency.

[0022] Furthermore, in order to ensure normal meshing of the drive gear 308 and the transmission gear 309, and to avoid the drive gear 308 and the transmission gear 309 having excessively large tooth diameters that would cause them to come into contact with the soil, an additional transmission gear 309 can be added between the drive gear 308 and the transmission gear 309.

[0023] A leveling plate 4 is provided at the rear end of the bracket 1 along the working direction. The leveling plate 4 is raised and lowered on the bracket 1. By adjusting the height of the leveling plate 4, it can adapt to different soil flatness requirements. The leveling plate 4 is used to level the soil surface after trenching to ensure that the soil covering thickness is consistent during subsequent sowing, which facilitates subsequent field management.

[0024] In summary, the working principle of this solution is as follows: Equipment debugging: According to the row spacing requirements of the crop (corn or peanut), loosen the fixing screws 307 on the mounting sleeve 304 of the bidirectional auger 302, slide the bidirectional auger 302 along the connecting shaft 301 to the preset spacing, and tighten the fixing screws 307 to lock it; adjust the height of the plate 4 by rotating the lifting rod handwheel to keep it at a suitable distance from the soil surface (usually 3-5cm).

[0025] Start the equipment: Connect the bracket 1 to the traction equipment (such as a tractor), start the drive motor 203, the motor drives the power shaft 201 to rotate, the rotary tiller blades 202 rotate with the power shaft 201, at the same time the power shaft 201 drives the connecting shaft 301 to rotate through the meshing of the drive gear 308 and the transmission gear 309, and the bidirectional auger 302 rotates synchronously with the connecting shaft 301.

[0026] Loosening soil operation: The traction equipment drives the bracket 1 forward along the operation direction. The rotary tillage blades 202 at the front end first cut and break the surface layer of the land in the planting area, loosening the compacted soil into a loose state, in preparation for subsequent ditching.

[0027] Trenching operation: The loosened soil moves forward with the support frame 1 into the trenching device 3 area. The rotating bidirectional auger 302 pushes the soil evenly to both sides through symmetrical spiral blades to form planting trenches with consistent depth and flat walls. The trench spacing is consistent with the spacing of the bidirectional auger 302.

[0028] Leveling operation: After the trench is dug, the surface of the soil is leveled by the leveling plate 4 at the rear end of the bracket 1 to eliminate the height difference of the soil accumulation on both sides of the trench, so that the surface of the planting area is flat, which facilitates subsequent sowing, covering and other operations.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
