[0023] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, obvious and easy to understand, the specific embodiments of the utility model are described in detail below. In the following description, a large number of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0024] Please refer to Figures 1 to 5 The seed covering device of the seedling tray of the embodiment comprises a frame unit and a covering unit.

[0025] The frame unit comprises a bearing conveying table 11, a support 12 arranged above the bearing conveying table 11, a sliding frame 13 which is liftable and slidably installed on the support 12, and a first driving mechanism 14 which can drive the sliding frame 13 to move up and down. A plurality of mounting holes 15 are arranged on the sliding frame 13 in the width direction of the bearing conveying table 11, and the mounting holes 15 should correspond to the holes in the seedling tray.

[0026] Specifically, the bearing conveying table 11 is mainly used for bearing and conveying the seedling tray, and can be a flow line in the form of a belt or a plate chain. In the working state, the bearing conveying table 11 drives the seedling tray to continuously move forward. The support 12 comprises two support columns 121 which are respectively installed on the two sides of the bearing conveying table 11, and a cross beam 122 which is installed on the top of the two support columns 121. The sliding frame 13 comprises a lower sliding beam 131 and an upper sliding beam 132 which are movably sleeved on the support columns 121 at different heights, and a sliding rail 133 which is installed between the lower sliding beam 131 and the upper sliding beam 132. The sliding frame 13 as a whole can move up and down along the support columns 121, and the plurality of mounting holes 15 are formed on the lower sliding beam 131. The first driving mechanism 14 is a first electric push rod, the base of the first electric push rod is installed on the cross beam 122, the telescopic rod of the first electric push rod extends downward and is connected with the upper sliding beam 132. Through the telescopic action of the telescopic rod, the upper and lower movements of the sliding frame 13 can be driven.

[0027] The covering unit comprises two pairs of covering claws 21 which are elastically arranged in the mounting holes 15 through the spring 22, a sliding cone 23 which is slidably installed on the upper part of the covering claw 21, and a second driving mechanism 24 which can drive the sliding cone 23 to move up and down. The upper part of the covering claw 21 forms a conical space, and the sliding cone 23 slides in the conical space to make the covering claw 21 move between opening and closing.

[0028] Specifically, the sliding rod 25 is installed on the top of the plurality of sliding cones 23, and the two ends of the sliding rod 25 are slidably installed on the slide rails 133. The second driving mechanism 24 is a second electric push rod, the base of the second electric push rod is installed on the upper slide beam 132, and the telescopic rod of the second electric push rod is connected with the sliding rod 25. Through the telescopic action of the telescopic rod, the up-down movement of the sliding rod 25 can be driven, and then the sliding of the sliding cone 23 in the conical space is driven. When the sliding cone 23 gradually slides downward from the top, the soil cover claw 21 is pushed to the two sides by the sliding cone 23, and when the sliding cone 23 moves upward, the soil cover claw 21 moves to the inner side under the action of the spring 22.

[0029] In order to improve the soil covering effect, the soil cover claw 21 is sequentially provided with an inclined plate portion 211, a vertical portion 212 and a bent portion 213 from top to bottom. The outer side of the vertical portion 212 is installed in the mounting hole 15 through the spring 22, the other end of the spring 22 is fixedly connected in the mounting hole 15, the inclined plate portion 211 is inclined outward from the top of the vertical portion 212, and the inclination angle is about 120°. The bent portion 213 is inclined inward from the top of the vertical portion 212 and is in a pointed shape. During work, the plurality of inclined plate portions 211 form a conical space, the vertical portion 212 is responsible for supporting and can move transversely in the mounting hole 15, and the bent portion 213 is inserted into the hole soil to realize the soil covering operation.

[0030] The working principle of the seed soil covering device of the seedling tray is as follows:

[0031] During work, the plurality of seedling trays are arranged at intervals on the bearing conveying table 11, and the bearing conveying table 11 drives the seedling trays to move forward. When a seedling tray moves to a predetermined position in front of the soil cover claw 21, the second driving mechanism 24 drives the sliding cone 23 to slide into the conical space so that the soil cover claw 21 is opened, the first driving mechanism 14 drives the sliding frame 13 to move downward, so that the soil cover claw 21 is inserted into the hole soil of the seedling tray, then the first driving mechanism 14 drives the sliding frame 13 to move upward, and at the same time, the second driving mechanism 24 drives the sliding cone 23 to move upward and gradually leave the conical space. At this time, the soil cover claw 21 is converted from opening to closing as a whole, so that the soil is brought to the seed in the central position of the hole, and the seed covering operation is realized. After completion, the bearing conveying table 11 continues to move forward by a distance, and the above-mentioned operation is repeated to operate the next row of holes. It can be seen that through the arrangement of the frame unit and the soil covering unit, the seed covering operation in the hole of the seedling tray can be realized, and manual operation is reduced, which has the advantages of labor saving and practicality.

[0032] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
