Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a transplanter for crop seedlings such as straw grass, and more specifically, it removes a crop seedling placed on a seedling stand and sent to a seedling outlet formed on the seedling stand from the seedling outlet. A plurality of planting claws to be planted in the field are provided, and prior to the operation of taking out the planting claws of the planting claws, they act on the plant seeds to be planted and push the planting seeds toward the seedling taking-out port. The present invention relates to a seedling transplanter provided with a seedling holder that can be switched between a maintaining posture and a retracting posture.

[0002]

[Prior Art]

 In the above-mentioned seedling transplanting machine, conventionally, the cam type drive mechanism arranged in the chain transmission case for transmitting power from the planting transmission case to the pair of left and right row planting mechanisms is connected to the above-mentioned structure via the link mechanism. The seedling holder was configured to be driven, and one cam type drive mechanism and one set of link mechanism were configured to drive the pair of left and right seedling holders similarly to the planting mechanism.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional structure simplifies the power transmission structure by driving a pair of planting mechanisms via one chain transmission mechanism, but the pair of seedling holders is also a pair. Since the plants are integrally driven by a single drive mechanism, for example, even if the planting timings of the left and right planting mechanisms are slightly different due to an assembly error, left and right seedling holding The tool driving timing is always performed simultaneously on the left and right. As a result, even if the operation timings of the planting claw and the seedling holder are adjusted in any of the articles, the operation timings of the other articles will be slightly deviated and the seedling removal operation will be smooth. There was a possibility that it would not be done and there was room for improvement. The present invention aims to solve the above-mentioned problems.

[0004]

[Means for Solving the Problems] A feature of the present invention is that, in the seedling transplanter described at the beginning, a plurality of the seedling holders are provided for each row so as to correspond to each of the above-mentioned planting claws. It is linked with a crank swing mechanism for vertically driving the planting pawl so as to switch between the working posture and the retracted posture.

[0005]

[Action]

 A seedling holder that holds seedlings when the seedlings are taken out by the planting claws is provided for each row corresponding to each row of the planting claws, and the crank swing mechanism for vertically moving the planting claws operates. Since the posture switching operation is performed by using the, the operation timing of the planting claw and the seedling holder can be set for each line even when there is an assembly error. Further, even if one seedling holder is clogged due to foreign matter being caught or malfunction occurs, the harmful effects such as the seedling holders on the adjacent strips stopping integrally are eliminated.

[0006]

[Effect of the device]

 Therefore, by reasonably improving the structure, it is possible to prevent deviations in the operation timing between the planting claw and the seedling holder for each row due to assembly errors, etc., and to facilitate seedling planting operation. became.

【Example】

 Embodiments will be described below with reference to the drawings. Fig. 1 shows a strawberry seedling transplanter. This seedling transplanter mounts strawberries and puts the seedling stand 2 that reciprocates left and right at a predetermined pitch with respect to the framed transmission case 1 that also serves as a frame, and seedlings are planted one by one from the lower end of the seedling stand 2. It is equipped with a planting mechanism 3 for taking out and planting it in the field, a seedling holder 4 for acting on the seedlings to hold the seedlings prior to the operation of taking out the seedlings by the planting mechanism 3, a grounding float 5 sliding on a mud surface, etc. 6 It is structured in a row planting format. The seedling placing table 2 is provided with a vertical feeding device 7 for feeding the placed seedlings toward the seedling take-out port 6, and a partition wall 8 for holding and holding the strawberries seedlings in a vertical posture is provided for each row. A push plate 9 that slides from the rear side by its own weight and pushes while preventing the seedlings from falling is provided so that the strawberries can be sent to the seedling take-out port 6 in a vertical position. The planting mechanism 3 drives a planting case 11 having a planting claw 10 at its tip by a crank rocking mechanism 12 so that the planting claw 10 moves up and down while drawing a substantially elliptical locus in a side view. The seedlings are taken out one by one from the take-out port 6 and are planted in a field.

A plurality of seedling holders 4 are provided for each row so as to correspond to each of the planting claws, and the operation is performed in conjunction with a crank swing mechanism 12 for vertically moving the planting claws 10. It is linked so that it can be switched between posture and retracted posture. The crank rocking mechanism 12 has a rear end of the planting case 11 supported by a rocking arm 13 pivotally supported on the planting transmission case 1 so as to be swingable back and forth around a horizontal axis P, and in the middle of the planting case 11. Part is pivotally connected to a rotary arm 15 which is rotationally driven by a drive shaft 14 in the planted transmission case 1, and by driving the rotary arm 15, the planted pawl 10 draws an elliptical locus in a side view. It is configured to make a crank movement. The seedling holder 4 is swingably supported forward and backward with respect to the planted transmission case 1 via front and rear swing links 17 and 18, and a holding claw 19 at the tip acts on the seedling to be planted to remove the seedling. The posture can be switched between an action posture of pushing toward 6 and a retracting posture of retracting to the rear. This seedling holder 4 switches from the retracted posture to the working posture prior to the seedling taking-out operation by the planting claw 10, and after the seedling taking-out operation from the seedling taking-out port 6 by the planting claw 10 ends, the working posture is changed. It is configured to switch to a retracted posture. More specifically, the other end of the front swing link 17 is extended below the pivot point, and an elongated hole 20 is formed in this extended portion. The connecting shaft 21 with the planted case 11 is inserted and engaged. With this structure, the posture is restricted by the elongated hole 20 and the connecting shaft 21 as the crank rocking mechanism 12 is driven, and the rocking motion is performed back and forth. Then, the holding claws 19 on the tip side penetrate into the seedlings to be planted and perform a holding action.

It should be noted that reference numerals are added to the section of the scope of claims for utility model to facilitate comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
