The planting units, LU506137 arranged in multiple sets on the two beams, with units on either side of the beams dedicated to maize planting and the remaining units for soybean planting. Each planting unit includes a fixed frame with two sets of pipes affixed to it. These pipes are separately encased onto the beams, with positioning holes on either beam and pipe, detachably connected by positioning pins. The fixed frame also features a furrow opener, fertilizer spreader, and seed sower, with the axis linked to the seed sower for transmission.

Optionally, the fertilizer spreader comprises a fertilizer trough fixedly attached to a fertilizer pipe mounted on the fixed frame. The trough includes spillage holes communicating with the fertilizer pipe.

In an additional option, the fertilizer pipe has an internal spillage plate with spillage holes, a blocking ring, and a shielding plate placed between the spillage plate and the blocking ring. A rotating rod extends through the spillage plate and out of the fertilizer trough, with one end of the rod connected to a first knob, away from the shielding plate.

Further, the seed sower incorporates a seed trough fixed to a feeding device, attached to the installation frame via side panels and reinforcing bars. The feeding device, transmissionally linked to the rotating axis, includes a feeding tube, with multiple covering plates fixed to the side panels, and the discharge end of the feeding tube positioned between two covering plates.

Preferably, the feeding device comprises a housing firmly connected to the reinforcing bar. Within the housing, a rotating wheel is installed, featuring multiple recesses along its outer edge. The rotating wheel's center is fixed to a first central axis, rotating within the housing and extending outwards. This first central axis is transmissionally connected to the rotating axis. The housing contains an inlet and an outlet, with the inlet connected to the seed trough and the outlet linked to the feeding tube.

Additionally, the furrow opener includes an outer square tube housing an inner square column that slides inside. The inner column, away from the outer tube, is fixedly connected to a soil-breaking blade. The outer tube incorporates a threaded rod, connected through a threaded hole in the inner column. The threaded rod LU506137 extends outwards from the outer tube, with one end fixed to a second knob.

Moreover, the outer square tube is fixedly connected to two fixed plates, with a rotating plate positioned between them. The rotating plate can rotate between the fixed plates. The threaded rod passes through both fixed plates, firmly connecting with the rotating plate.

Furthermore, the side panel has a pivotally connected extension rod, ending in a compacting wheel away from the side panel. An air cylinder is articulated between the extension rod and the reinforcing bar.

Additionally, the rotating axis has first pulleys fixed at both ends, while the ends of the beams are externally connected to roller frames. The roller frames have second central axes fixed at their centers, rotating on the roller frames. These second central axes are connected to second pulleys, which are interconnected by a belt drive with the first pulleys.

Further, multiple third pulleys are slidably connected to the rotating axis. A fourth pulley is fixedly connected to the first central axis. The third pulleys and the fourth pulley are linked by the belt drive. The rotating axis has teeth on its exterior, while the third pulleys have through-holes with inner teeth that correspond to the external teeth.

DETAILED DESCRIPTION OF THE INVENTION LU506137

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

Referring to Figures 1-7, the present invention provides a combined corn-soybean planter, comprising:

Connection frame 1, designed to connect with agricultural machinery.

Mounting frame 2, fixedly connected to connection frame 1. It holds multiple planting units and is equipped with two parallel beams 3, each end of which has two rollers 4. The frame 2 has a rotational connection with the spindle 5, which is in a driving connection with the rollers 4. The mounting frame 2 is connected to the connection frame 1. When operated by agricultural machinery, the rollers 4 make contact with the ground and drive the spindle 5's rotation.

The planting units, arranged in several groups, are positioned on the beams 3.

Those situated on the sides of beams 3 are designated for planting corn, while the remaining units are for soybeans. Each planting unit comprises a fixed frame 6 attached with two sets of pipes 7, slidably placed on beams 3. Both the beams 3 and pipes 7 have positioning holes for detachable positioning pins 8. The fixed frame 6 includes trenching, fertilizer spreading, and seed sowing devices, all connected to the spindle 5 for operation.

The corn is planted on the side planting units of beams 3, while the soybeans are on the others, allowing easy intercropping of soybeans between corn rows. The fixed frame 6, using the pipes 7, can slide along the beams 3, adjusting the spacing between rows. Once the desired position is set, positioning pins 8 are inserted into the LU506137 holes on pipes 7 and beams 3. The trencher digs planting furrows, the fertilizer spreader distributes fertilizer in the furrows, and the seed sower plants seeds. They are aligned on a straight line, with the trencher upstream of the fertilizer spreader and the seed sower upstream of both.

Further optimizing the solution, the fertilizer spreader comprises a fertilizer trough 9, fixedly connected to a fertilizer pipe 10, which is secured to the fixed frame 6. The fertilizer trough 9 has leakage holes connected to the fertilizer pipe 10 for the passage of fertilizer.

Fertilizer is poured into the trough 9 and, under gravity, flows downward through the fertilizer pipe 10 into the prepared furrows.

In a more detailed optimization, there is an internal fixture of a leakage plate 11 within the fertilizer pipe 10, containing holes that allow the fertilizer to leak. A barrier ring 12 is fixed within the fertilizer pipe 10, and the leakage plate 11 is positioned above the barrier ring 12. Between the leakage plate 11 and the barrier ring 12, a blocking plate 13 is placed, with a rotary rod 14 fixedly attached to it. The rotary rod 14 passes through the leakage plate 11, extends out of the fertilizer trough 9, and is fixedly connected to the first knob 15 at one end away from the blocking plate 13.

Fertilizer drops through the holes in the leakage plate 11 (not shown in the diagram). The blocking plate 13, which can be an arc-shaped plate rather than a circular one, covers the holes in the leakage plate 11, allowing for adjustment of the fertilizer quantity. By turning the first knob 15, the rotary rod 14 moves the blocking plate 13, which covers the leakage holes.

Additionally, the seed sower consists of a seed trough 16 connected to a feeder, the latter being fixedly connected to the reinforcement bar 18 on the fixed frame 6.

The feeder is in driving connection with the spindle 5 and is fixedly connected to a feeding pipe 19. Furthermore, the side plate 17 on the fixed frame 6 is connected to several covering plates 20, and the outlet of the feeding pipe 19 is situated between these covering plates 20.

Seeds are poured into the seed trough 16, and they move into the feeder. Under the spindle 5's drive, the feeder releases the seeds into the feeding pipe 19. These seeds then drop into the prepared furrows and are covered by the covering plates 20 LU506137 with soil. Both covering plates 20 work simultaneously, pushing soil from both sides of the furrows to cover the seeds.

Further optimizing the system, the feeder consists of a casing 21, fixedly connected to the reinforcement bar 18. Inside the casing 21, there is a rotary connection with a wheel 22, which has several grooves 23 on its outer edge. The wheel 22 is centrally connected to a first central axis 24, rotating within the casing 21. The first central axis 24 extends out of the casing 21 and is in driving connection with the spindle 5. The casing 21 has separate inlet and outlet ports; the inlet is connected to the seed trough 16, while the outlet is linked to the feeding pipe 19.

The spindle 5 drives the rotation of the first central axis 24, causing the wheel 22 to turn. As the wheel 22 rotates over the seed trough 16, the seeds enter the grooves 23 on the wheel 22. Due to the minimal clearance between the casing 21 and the wheel 22, the seeds remain in the grooves until the wheel 22 rotates to the side of the feeding pipe 19, allowing the seeds to drop out due to gravity.

In addition, the furrow opener comprises an outer tube 25 with an inner column 26 sliding inside it. The inner column 26, fixed at one end to a soil-breaking knife 27, has a threaded hole, and a threaded rod 28 rotates within this hole. Extending out of the outer tube 25, the threaded rod 28 is fixedly connected to the second knob 29 at one end.

The soil-breaking knife 27 serves to create furrows, while rotating the second knob 29 drives the threaded rod 28. This motion allows the inner column 26 to move up and down, facilitating adjustments to the furrow depth.

Further optimizing the design, the outer tube 25 is firmly connected to two fixed plates 30, and a turning plate 31 is positioned between these fixed plates 30. The turning plate 31 is set to rotate between the two fixed plates 30, and the threaded rod 28 passes through both fixed plates 30, establishing a fixed connection with the turning plate 31.

As the threaded rod 28 drives the turning plate 31 between the two fixed plates 30, this action prevents the threaded rod 28 from moving up and down.

Additionally, the side panel 17 has a rotating connection with an extension rod 32. LU506137

The extension rod 32, at its far end from the side panel 17, is pivotally connected to a compacting wheel 33, and there is a hinge connection between the extension rod 32 and the reinforcement bar 18, operated by a cylinder 34.

The compacting wheel 33 serves to compact the soil covering the furrows, and the cylinder 34 applies a certain amount of pressure to the extension rod 32, increasing the pressure exerted by the compacting wheel 33.

Moreover, the spindle 5 is fixedly connected at both ends to a first belt wheel 35, while two roller frames 36 are fixedly connected to the ends of the beam 3. The central position of the rolling wheel 4 is connected to a second central axis 37, which is rotatingly connected to the roller frame 36. The second central axis 37 is fixedly connected to a second belt wheel 38. The first belt wheel 35 is connected to the second belt wheel 38 through a belt drive.

The rolling wheel 4 is connected to the roller frame 36 through the rotation of the second central axis 37. The rotation of the second central axis 37 drives the second belt wheel 38, which, in turn, drives the first belt wheel 35 via the belt, thereby rotating the spindle 5.

Lastly, the spindle 5 has several sliding connections with a third belt wheel 39, while the first central axis 24 is fixedly connected to a fourth belt wheel 40. The third belt wheel 39 is connected to the fourth belt wheel 40 via a belt drive. Furthermore, there are several teeth 41 on the external part of the spindle 5, while the third belt wheel 39 has through-holes with internal grooves that are suitably aligned with the teeth 41.

The shaft (5) drives the third pulley (39), which, in turn, moves the fourth pulley (40) via a belt. This rotation affects the first central axis (24). The shaft (5) passes through a through-hole and has several teeth (41) on its exterior, allowing it to rotate the third pulley (39). While the third pulley (39) can slide along the length of the shaft (5), there is some friction between them, preventing the pulley from sliding arbitrarily when the shaft (5) rotates. The area where the shaft (5) connects to the mounting frame (2) doesn’t have teeth (41).

The operation of this device involves connecting it to agricultural machinery via LU506137 the connecting frame (1). Once connected, the depth for trenching is set. Rotating the second knob (29) drives the threaded rod (28), causing it to rotate within the inner column (26). Because both the outer pipe (25) and inner column (26) are square, the threaded rod (28) can move the inner column (26) up and down, allowing the soil opener (27) to penetrate the soil. The fertilizer amount is adjusted by rotating the first knob (15), which moves the blocking plate (13) to partially cover the fertilizer holes in the leak plate (11). The planting row spacing is adjusted by removing and inserting the locating pin (8) after adjusting the fixed frame (6) position on the beams (3).

During planting, seeds are poured into the seed trough (16), and fertilizer is placed into the fertilizer trough (9). The agricultural machinery moves the device, causing the rollers (4) to rotate. This rotation moves the second central axis (37) via the second pulley (38), which, through the belt, turns the first pulley (35), thereby rotating the shaft (5). The shaft (5) then moves the third pulley (39), and the movement is transmitted to the fourth pulley (40) via the belt. Consequently, the first central axis (24) rotates, driving the wheel (22). When the wheel (22) reaches the seed trough (16), the seeds fall into its grooves (23) due to the small gap between the wheel and the shell (21), preventing seed loss. As the wheel (22) rotates towards the feeding tube (19), gravity causes the seeds to drop into the pre-dug trench.

Simultaneously, the fertilizer flows downward through the fertilizer tube (10) into the trench due to gravity. Soil covering plates (20) then cover the seeds and fertilizer, and the compaction wheel (33) presses the soil in the trench.

The above-described embodiments only describe preferred modes of the present LU506137 invention and do not limit the scope of the present invention.

Without departing from the design spirit of the present invention, those of ordinary skill in the art can make various modifications to the technical solutions of the present invention.

All deformations and improvements shall fall within the protection scope determined by the claims of the present invention.
