Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rice seedling raising, in particular to a rice planting and seedling raising device. Background Technique
[0002] The treated rice seeds are put into a seedling raising device and centrally raised in a greenhouse. After the seedlings grow to a certain height, they can be taken out for transplanting work.
[0003] For example, the publication (announcement) number: CN219660495U, a rice seedling planting device. After the storage pipe moves to the position of the sowing groove, manually pull the pull plate to move the partition plate. When the through hole on the partition plate moves into the storage pipe, the seeds fall into the groove through the through hole to complete sowing. The manual operation method cannot accurately control the time when the through hole enters the storage pipe, so it cannot achieve uniform sowing, and it is easy to have the problem that it is difficult to align the storage pipe with the sowing groove during manual operation. Content of the Utility Model
[0004] The utility model aims to solve at least the problem of limited accuracy and uniformity of rice sowing in the prior art.
[0005] This scheme provides a rice planting and seedling raising device, which is achieved by the following specific technical means: it includes a seedling raising box and a seedling raising box placed in the seedling raising box. The seedling raising box is provided with sowing grooves arranged in a matrix. Along the length direction of the seedling raising box, a walking frame is arranged. A plurality of groups of storage pipes are installed on the walking frame. A plurality of groups of storage pipes correspond to a row of sowing grooves one by one. A horizontal shaft is rotatably penetrated through the middle and lower part of the storage pipe. A material taking part is sleeved on the horizontal shaft. The material taking part rotates in the storage pipe for one week through the horizontal shaft to complete one seed taking;
[0006] A rotation control mechanism is arranged on the seedling raising box. The rotation control mechanism is intermittently connected to the horizontal shaft for controlling the rotation of the horizontal shaft.
[0007] Preferred Technical Solution 1: The ends of adjacent two groups of the horizontal shafts are fixedly connected to form a group of connecting shafts, so that a plurality of groups of horizontal shafts can rotate synchronously. At the same time, the rotation control mechanism includes a convex plate fixed on the side of the seedling raising box. A plurality of groups of short racks are arranged on the convex plate. Each group of short racks is in the same straight line as the corresponding row of sowing grooves. A driven gear is sleeved on the end of the connecting shaft. The driven gear is located above the short rack and meshes with a plurality of groups of short racks in turn during the movement of the walking frame. Each group of broken racks drives the driven gear to rotate for one week.
[0008] Preferred Technical Solution 2: A seed taking groove is arranged on the material taking part, and quantitative seed taking is realized by using the seed taking groove.
[0009] Preferred Technical Solution 3: The connecting shaft and the storage pipe are in a damping rotational connection.
[0010] Preferred Technical Solution 4: Tracks are fixed on both sides of the seedling-raising box. The bottom end of the walking frame travels along the tracks. A long rack is fixed on the tracks. A driving gear is fixed on the output shaft of the motor arranged in the walking frame. The driving gear meshes with the long rack, and the technical effect of driving the walking frame to automatically travel along the tracks is achieved by driving the driving gear to mesh with the long rack by the motor.
[0011] Preferred Technical Solution 5: The convex plates are distributed on both sides of the seedling-raising box.
[0012] Adopting the above structure enables this solution to have the following beneficial effects:
[0013] 1. By using the walking frame, the horizontal shaft, the seed-taking member and the rotation control mechanism, when the storage pipe moves to directly above the sowing groove, the seed-taking member takes seeds quantitatively and at a fixed point, avoiding the problem that the accuracy and uniformity of rice sowing are limited due to manual operation.

A walking frame 3 is arranged along the length direction on the seedling raising box 1. A plurality of storage pipes 4 are installed on the walking frame 3. The number of the storage pipes 4 is equal to the number of the sowing grooves 21 in a row of sowing grooves 21 and the positions correspond one by one. A horizontal shaft 51 is rotatably penetrated through the middle and lower part of the storage pipe 4. A seed taking member 6 is sleeved on the horizontal shaft 51. The seed taking member 6 is a spherical member, so that it can rotate in contact with the inner cavity wall of the storage pipe 4. The seed taking member 6 is provided with a seed taking groove 61. Quantitative seed taking is realized by using the seed taking groove 61. The horizontal shaft 51 drives the seed taking member 6 to rotate one week in the storage pipe 4 to complete one seed taking. A rotation control mechanism 7 is arranged on the seedling raising box 1. The rotation control mechanism 7 is intermittently connected to the horizontal shaft 51 and is used to control the rotation of the horizontal shaft 51. When the storage pipe 4 moves to the directly above the sowing groove 21, the rotation control mechanism 7 is connected to the horizontal shaft 51 to drive the horizontal shaft 51 to rotate.
[0023] Please refer to Figures 1 - 2 , a rice planting and seedling raising device.
