Description

TECHNICAL FIELD

[0001] The utility model relates to an agricultural machine, especially a device suitable for reed seedling production, in particular to a reed seedling feeding device. BACKGROUND

[0002] With the development of modern agriculture, the planting of reed has been generally mechanized. Among them, in the aspect of reed seedling transmission, a reed cutting mechanical seedling feeding device is currently used. The device includes a seedling rod box and the like, and the seedling rod box is designed with a length, width and height of 300mm, 200mm and 150mm respectively according to the cutting length of reed seedling stems. At the same time, ribs are designed inside the seedling rod box. Each rib is spaced 500mm apart, and the width of the rib is 400mm. An axle belt mechanism is provided below the seedling rod box, and a plurality of arc-shaped grooves are provided on the belt in the axle belt mechanism, as shown in Figure 1 .

[0003] In use, the device is hung on a tractor or other power source, so that the axle belt mechanism rotates to drive the belt to rotate. Then, the reed seedling stems are fed into the seedling stem box from the top, and under the action of the ribs, the reed seedling rods are dropped into the grooves on the belt in the same direction as the grooves. The reed seedling rods in the grooves are transported to the subsequent mechanism by the rotation of the belt, and the cutting of the reed seedling rods is completed.

[0004] However, due to the non-uniform diameter of the reed seedling rods, the seedling may be missed or stuck, which may cause the subsequent cutting to be interrupted and greatly affect the production process.

[0005] Therefore, it is urgent to improve it in order to better meet the needs of agricultural production. INVENTION CONTENTS

[0006] The utility model aims at the shortage of prior art, and provides a reed seedling feeding device, which can effectively solve the problems of missing seedlings and stuck seedlings and ensure the smooth progress of the cutting process of reed seedlings.

[0007] The technical scheme of the utility model is:

[0014] Furthermore, the thickness of the turntable is adapted to the depth of the housing.

[0015] Furthermore, there are two discharge holes, both of which are round holes and are arranged symmetrically at 180°.

[0016] Furthermore, the rotating shaft is mounted in the first mounting hole via a bearing.

[0017] Furthermore, the lower end of the rotating shaft is connected to the servo motor via a servo disc.

[0023] The beneficial effects of this utility model are:

[0024] This utility model features a reasonable design, simple structure, and convenient use. It allows the straightened reed seedlings to be placed in the feeding holes of a turntable. The rotation of the turntable causes the seedlings in each feeding hole to pass through the discharge hole of the shell and the connecting hole on the pad before falling onto the conveyor belt below, thus conveying them to the next mechanism. This achieves efficient feeding of the reed seedlings. Furthermore, it effectively solves the problems of seedling leakage and jamming that easily occur with previous feeding mechanisms, creating favorable conditions for ensuring the successful planting of reed seedlings.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] like Figures 2 to 4 As shown.

[0032] A feeding device for Artemisia seedlings includes: a support 6, a shell 1, a turntable 4, and a rotating shaft 3.

[0033] The bracket 6 is a rectangular frame, and a mounting plate 8 is provided inside it. The mounting plate is strip-shaped and is horizontally arranged in the middle of the bracket 6.

[0034] The housing 1 is a cylindrical shape with a bottom but no top. A first through-hole 12 is provided at the center of its bottom plate, and at least one through-hole 11 is provided on the bottom plate surrounding the first mounting hole. The bottom surface of the housing 1 is mounted on the upper end of the support 6 via a pad 5, making the housing stable. Preferably, the depth of the housing 1 is approximately 10 cm to accommodate the length of the reed seedlings. There are two discharge holes 11, both circular, symmetrically arranged at 180°, with their centers located on the concentric circles of the housing 1, which helps improve discharge efficiency.

[0035] The pad 5 is a rectangular flat plate with an area larger than the bottom surface of the housing 1, fixing it to the upper end of the bracket 6 and securing the housing 1 to the pad 5 to ensure stable installation. The pad 5 has a second mounting hole 10 at its center, and at least one through-hole-shaped connecting hole 9 surrounding the second mounting hole 10. Preferably, there are two connecting holes 9, their size and number adapted to the discharge hole 11, and they correspond to and communicate with each other, facilitating the falling of the reed seedlings through the connecting holes. Simultaneously, the size and position of the second mounting hole 10 are adapted to the first mounting hole 12, facilitating subsequent installation.

[0036] The turntable 4 is disc-shaped, with an outer diameter smaller than the inner diameter of the housing 1, and its thickness matching the depth of the housing 1, allowing the turntable to be movably placed inside the housing, with both ends approximately flush. The turntable 4 has multiple material passage holes 2. These material passage holes 2 are circular through holes, arranged longitudinally along the turntable 4, and are the same size as the discharge holes 11. Furthermore, the material passage holes 2 are evenly distributed along concentric circles on the turntable 4. The radius of the concentric circle containing the center of each material passage hole 2 is the same as the radius of the concentric circle containing the center of the discharge holes 11, thus allowing each material passage hole to coincide with the discharge hole as the turntable rotates. Preferably, there are six material passage holes 2, each with a diameter of approximately 6 cm, which improves discharge efficiency while avoiding an excessively large turntable that would cause manufacturing and installation inconvenience.

[0037] The rotating shaft 3 is cylindrical and is installed through the center of the turntable 4. Its lower part is located below the turntable 4 and passes through the first mounting hole 12 of the housing 1 via a bearing 13. Its lower end passes through the second mounting hole 10 on the pad 5 and is connected to the servo motor 7 via the servo disc. The servo motor 7 is mounted on the mounting plate 8 and is electrically connected to a microcontroller so that the servo motor can rotate forward and backward under the control of the microcontroller. The servo motor 10 can be a 6V 15kg RC Digital Servo servo motor. The microcontroller is a 32-bit microcontroller. The upper part of the rotating shaft 3 is located above the turntable 4 for easy installation.

[0038] Furthermore, a pressure sensor is installed on the inner wall of the discharge port. This pressure sensor can be an RP-L flexible thin-film resistive pressure sensor, with a width equal to the thickness of the base plate of the housing and a length similar to the circumference of the discharge port, allowing it to be mounted inside the discharge port. Simultaneously, this pressure sensor is electrically connected to the microcontroller via an A / D conversion module, acquiring sensor data every 50ms and calculating its rate of change. If the servo motor malfunctions, or if other factors cause the feed port and discharge port to misalign, resulting in the seedlings not falling completely and becoming stuck between the misaligned feed port and discharge port, the stuck seedling will touch the sensor, causing it to sense pressure exceeding its set pressure change rate threshold. Subsequently, the microcontroller will immediately send a command to stop the servo motor from rotating, preventing the seedlings from being fatally crushed. Simultaneously, a buzzer on the microcontroller will sound an alarm, reminding the operator to recalibrate the position of the turntable and housing, and restart the device after adjustment.

[0039] The working process of this utility model is as follows:

[0040] Manually, the reed seedlings are neatly bundled into small bunches and placed vertically into the various feed holes of the turntable. Generally, about 16 seedlings can be placed in each feed hole. Then, the servo motor is activated, driving the turntable to rotate. This ensures that each set of feed holes aligns with the discharge hole on the casing, allowing the seedlings to fall through the discharge hole and connecting hole onto the conveyor belt below, completing one discharge cycle. As the turntable rotates, all the seedlings in each feed hole are emptied. Then, seedlings are manually replenished in a timely manner to achieve continuous production. During this process, the servo motor pauses briefly each time a seedling is discharged to ensure complete discharge. Furthermore, the inner walls of the feed holes are designed to be smooth, allowing the seedlings to slide down smoothly and effectively preventing them from getting stuck or piling up.

[0041] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
