Description

Technical Field

[0001] The invention relates to the technical field of agricultural automation, and in particular to a flexible parallel shunting bead dispenser. Background Art

[0002] With the advancement of agricultural modernization, demands for seeding efficiency and crop yields are increasing. Agricultural machinery is playing an increasingly important role in modern agricultural production. Traditional seeding methods typically rely on manual sorting or simple mechanical sorting. These methods are inefficient, error-prone, and unable to meet the demands of modern agriculture for high efficiency and precision farming. With the advancement of agricultural technology, automation and precision seeding technology have become important development directions. However, most existing automated seeding equipment can only process seeds of a single color or type and cannot effectively distinguish and sow seeds of two or more colors simultaneously.

[0034] like Figure 1-9 As shown, a flexible parallel diversion bead dispenser includes a frame 1, a silo assembly 3 mounted and fixed on the frame 1 for dividing and storing two different seeds, a dividing tray 2 fixed on the frame 1 for receiving seeds output from the silo assembly 3, and a sowing roller assembly 7 rotatably arranged under the frame 1 for receiving and sowing seeds output from the dividing tray 2.

[0035] The present invention proposes a flexible parallel diversion bead dispenser, which is provided with a frame plate 1, a hopper assembly 3, a distribution tray 2, and a sowing roller assembly 7. When in use, seeds (beads) of different types and colors are separated and stored through the hopper assembly 3, and seeds of the required type and color are output toward the sowing roller assembly 7 through the distribution tray 2, and are sown downward through the sowing roller assembly 7. The present invention provides an automated sowing solution, improves sowing efficiency, reduces labor costs, and ensures sowing accuracy and uniformity of crop growth.

[0036] As a further embodiment of the present invention, the silo assembly 3 includes a silo 31 having a storage space, a material receiving opening 32 formed on the top surface of the silo 31, and a discharge port 33 having a shape similar to that of the seeds formed on the bottom surface, a dividing shaft 36 is horizontally and rotatably arranged in the middle of the silo 31, and a dividing paddle 37 having a shape similar to that of the storage space is fixedly connected to the dividing shaft 36, and the dividing paddle 37 divides the storage space into a first space and a second space for accommodating two different seeds, and a dividing motor 35 for driving the dividing shaft 36 to rotate to form a dividing action is fixedly arranged on the outside of the silo 31.

[0037] The silo assembly consists of a silo 31 with a storage space for two different types of seeds. The top surface of the silo is designed with a receiving opening 32, which serves as the seed entrance. Seeds are typically fed into the silo via a seed dispenser 5. The bottom surface of the silo is designed with a discharge port 33 shaped like the seeds. This design helps control the speed and direction of seed discharge, ensuring that the seeds leave the silo in an orderly manner. The shape of the discharge port resembles the shape of the seeds, which reduces the risk of seeds getting stuck or accumulating during discharge.

[0038] In the middle of the silo 31, a dividing shaft 36 is arranged to rotate horizontally. A dividing paddle 37 with a shape similar to that of the storage space is fixedly connected to this shaft. The dividing paddle can effectively divide the storage space into two independent parts: a first space and a second space. These two spaces are used to accommodate two different kinds of seeds, respectively, thereby realizing the classified storage of seeds. In order to drive the dividing shaft 36 to rotate, a dividing motor 35 is fixedly provided on the outside of the silo 31. When seeds need to be distributed, the dividing motor is started, driving the dividing shaft 36 to rotate. As the dividing shaft rotates, the dividing paddle also rotates, thereby changing the separation state between the first space and the second space. This dynamic separation mechanism can adjust the distribution ratio or order of seeds as needed to achieve flexible dividing action.

[0039] As a further embodiment of the present invention, the bottom wall of the storage space of the silo 31 is inclined, and the discharge port 33 is located at the lower side. A silo support 34 is provided at the bottom of the silo 31. Several side frames 11 are integrally formed on the outer side of the frame plate 1. The upper portions of the side frames 11 are fixedly connected to the sides of the silo 31 and the silo support 34. The inclined bottom wall of the storage space of the silo 31 promotes the natural descent of seeds. Once the seeds are distributed to the appropriate position within the storage space by the seed-dispensing paddles, they slide down the inclined surface to the discharge port 33 at the lower side.

[0040] As a further embodiment of the present invention, a column 4 is fixedly provided vertically upward on the back of the silo 31, a seed dispenser 5 is fixedly provided on the upper part of the column 4, and a gate opening motor for opening and closing the gate is fixedly provided on the column 4.

[0041] As a further embodiment of the present invention, the material distribution plate 2 can be rotatably arranged between the material bin 31 and the frame 1, and a rotating motor for driving the material distribution plate 2 to rotate is arranged at the bottom of the frame 1. The material distribution plate 2 is a circular structure and a pair of material distribution holes 21 are vertically penetrated at its circumference. A pair of material discharge outlets 12 are vertically penetrated at the positions of the material distribution holes 21 on the frame 1. The material distribution holes 21 rotate to the discharge port 33 to form a material receiving action, and the material distribution holes 21 after receiving the material rotate to the position of the material discharge outlet 12 to form a material discharge action.

[0042] When the dividing disc 2 rotates to a certain position, one of the dividing holes 21 will be exactly aligned with the discharge port 33 of the silo. At this time, the seeds falling from the silo will enter the dividing hole 21 through the discharge port 33, completing the material receiving action. After the material receiving is completed, the dividing disc 2 continues to rotate, and the dividing hole 21 carrying the seeded seeds moves to the next position. In this process, the seeds in the dividing hole 21 are temporarily stored, waiting for the next step of the unloading action. As the dividing disc 2 continues to rotate, when the dividing hole 21 carrying the seeds rotates to the position of the unloading outlet 12 on the frame plate, the seeds will be discharged through the combined channel of the dividing hole 21 and the unloading outlet 12, enter the subsequent processing flow, and fall onto the sowing roller assembly 7, completing the unloading action.

[0043] The three actions of receiving, rotating and waiting, and discharging are repeated in a cycle, continuously distributing the seeds in the silo to different discharging outlets according to a set pattern, thereby achieving orderly distribution and delivery of seeds. Through this working principle, the distributing system can efficiently distribute the seeds in the silo to different discharging outlets 12, and thus to different sowing rollers 71, forming parallel diversion sowing to meet different sowing or processing needs.

[0044] As a further embodiment of the present invention, a pair of side panels 6 are formed vertically downward on both sides of the bottom of the frame plate 1, and the sowing roller assembly 7 includes a sowing roller 71 rotatably arranged between the two side panels 6, and a number of sowing cylinders 72 centrally and symmetrically arranged around the sowing roller 71, and each of the sowing cylinders 72 has a sowing opening at the end away from the axis. During the rotation of the sowing roller 71, each of the sowing cylinders 72 is opposite to the discharge outlet 12.

[0045] The sowing roller assembly 7 is designed and mounted on the bottom of the frame 1, supported and positioned by two vertically downward-facing side panels 6. The rotatable sowing roller 71, located between the two side panels 6, serves as the core component of the sowing process. Several sowing cylinders 72 are symmetrically arranged around the periphery of the sowing roller 71. These sowing cylinders are evenly distributed along the circumference of the sowing roller. Each sowing cylinder has a sowing opening at the end away from its axis. This opening serves as a channel for the seeds to be released from the sowing cylinder into the field. When the sowing roller 71 begins to rotate, it drives the surrounding sowing cylinders 72 to rotate with it. During rotation, each sowing cylinder 72 passes a position opposite the discharge outlet 12. When the sowing opening of a sowing cylinder 72 aligns with the discharge outlet 12, the seeds previously distributed to the discharge outlet by the distribution system fall into the sowing cylinder. As the sowing roller continues to rotate, the seed-filled sowing cylinder continues to rotate until its sowing opening is aligned with the sowing notch 63. At this point, the seeds are released into the field through the sowing opening, completing the sowing operation. This cycle is repeated continuously, allowing the sowing roller assembly to continuously and evenly sow seeds into the field, achieving efficient sowing operations. At the same time, because the sowing cylinder is arranged symmetrically, the uniformity and consistency of sowing can be ensured. Since the sowing roller 71 is provided with two, different discharge outlets 12, they are distributed to different sowing rollers 71, forming parallel diversion sowing.

[0046] As a further embodiment of the present invention, a fixed bead plate 61 is formed on the opposite side of the two side plates 6 and extended inward, and a plate opening 73 allowing the fixed bead plate 61 to extend into is correspondingly provided at the middle position of each sowing cylinder 72. The fixed bead plate 61 limits the seeds in the space between the bottom of the sowing cylinder 72 and the fixed bead plate 61, and a discharge notch 62 is formed at the position of the fixed bead plate 61 corresponding to the discharge outlet 12, and a sowing notch 63 is formed at the lower part of the fixed bead plate 61.

[0047] To more precisely control the flow and release of seeds, retaining plates 61 extend from the inner sides of the two side panels 6. These retaining plates correspond to the center of the sowing cylinder 72. Each sowing cylinder 72 is equipped with a plate opening 73 that allows the retaining plates 61 to extend into the cylinder. As the sowing roller 71 rotates, the retaining plates 61 remain within the plate openings 73, confining the seeds in the space between the bottom of the sowing cylinder and the retaining plates 61. This prevents the seeds from falling out of the sowing cylinder even while the sowing roller rotates. Instead, the retaining plates effectively secure the seeds. Only when the sowing cylinder 72 rotates to the position corresponding to the discharge outlet 12 will the discharge notches 62 formed in the retaining plates 61 align with the discharge outlet 12, allowing the seeds to fall into the sowing cylinder from the discharge outlet. At this point, the seeds remain confined within the sowing cylinder by the retaining plates until the sowing cylinder continues to rotate to the sowing position. At this position, the sowing notches 63 formed at the bottom of the retaining plates align with the sowing opening of the sowing cylinder. At this point, the seeds can be released into the field through the sowing opening and sowing gap, completing the sowing process. The design of the fixed bead plate allows the sowing roller assembly to more precisely control the flow and release timing of the seeds, ensuring that the seeds are sown in the field at the right location and time, improving sowing accuracy and efficiency.

[0048] As a further embodiment of the present invention, a paddle limiting assembly 9 is provided between the discharge outlet 12 and the sowing roller 71, and the paddle limiting assembly 9 includes a left paddle limiting plate 91 and a right paddle limiting plate 92 which are arranged on the side opposite to the two side plates 6 and rotate coaxially with the sowing roller 71, and the opposite sides of the left paddle limiting plate 91 and the right paddle limiting plate 92 extend inwardly to form an arc-shaped plate with a wave structure, and the arc-shaped plate is a convex surface 96 and a concave surface 97 spliced ​​with several smooth arcs, and the convex surfaces 96 and concave surfaces 97 of the arc-shaped plates on both sides are staggered and opposite to each other; a discharge plate 93 is fixedly provided on the bottom side of the discharge outlet 12, and a paddle 94 is movably connected to the bottom of the discharge plate 93, and a paddle through hole 95 is provided on the paddle 94 corresponding to the position of the discharge outlet 12, and the two ends of the paddle 94 respectively conflict with the convex surface 96 or the concave surface 97 of the arc-shaped plates on both sides.

[0049] As the seeding roller 71 rotates, the left and right paddle stop plates 91 and 92 rotate synchronously. Because the curved plate has a wavy structure, the ends of the paddle 94 continuously move left and right along these convex and concave surfaces. Specifically, when one end of the paddle 94 rests on the convex surface 96 of a curved plate, it is pushed leftward; when it moves to the concave surface 97, it is pushed rightward. This alternating up and down movement causes the paddle 94 to oscillate, thereby changing the relative position between the paddle hole 95 and the discharge outlet 12. This design allows for precise control of the timing and quantity of seed discharge. When the paddle hole 95 is aligned with the discharge outlet 12, seeds can smoothly fall from the discharge outlet into the sowing cylinder 72 of the seeding roller 71. However, when the paddle hole 95 is blocked by the paddle 94, seed discharge is prevented. By adjusting the wavy shape of the curved plate and parameters such as the length and position of the paddle 94, the discharge quantity and frequency can be precisely controlled. Among them, the paddle 94 is provided with long sliding holes on the left and right sides. The paddle is connected to the blanking plate 93 through bolts, and the paddle can slide left and right along the direction of the long sliding holes.

[0050] As a further embodiment of the present invention, a sowing guide rail 8 is provided for cooperating with the sowing roller 71. The sowing guide rail 8 is provided with sowing holes evenly spaced apart. Left and right baffles 64 are symmetrically provided on opposite sides of the two side panels 6 for cooperating with the sowing guide rail 8. The sowing guide rail is provided, and the sowing cylinder is extended into the sowing holes in the sowing guide rail. When the device is pushed along the length of the guide rail, the sowing roller can be driven to rotate synchronously, thereby achieving automatic sowing.

[0051] As a further embodiment of the present invention, an auxiliary plate for guiding the seeds to the discharge port 33 is formed on the lower side of the dividing paddle 37 .

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0053] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
