[0026] After introducing the basic principle of the utility model, various non-limiting embodiments of the utility model are specifically introduced below. Any number of elements in the drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0027] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0028] Embodiment 1 of the hole-digging device for transplanting tobacco seedlings provided by the utility model:

[0029] like Figure 1and Figure 2 As shown, the hole-digging device for transplanting tobacco seedlings includes a hole-digging tube 1 and an auxiliary hole-digging shaft 4. The hole-digging tube 1 has a drill shaft 2 at the lower end and a gripping portion at the upper end for an operator to grip. In this embodiment, the upper end of the hole-digging tube 1 has a straight rod 3, which constitutes the gripping portion.

[0030] On this basis, the auxiliary hole-opening shaft 4 is located inside the hole-opening tube 1. The hole-opening tube 1 has an outlet 5 at the lower end. A detachable plug (not shown in the figure) is installed at the outlet 5. The auxiliary hole-opening shaft 4 is used to extend from the outlet 5 to assist in hole opening. In addition, it also includes a driving member, which extends into the hole-opening tube 1 and is connected to the auxiliary hole-opening shaft 4 to facilitate the operator to press the auxiliary hole-opening shaft 4 downward and then extend it from the outlet 5.

[0031] A horizontal plate 6 is fixed to the outer periphery of the hole-opening tube 1, and the horizontal plate 6 is defined as having a left plate and a right plate located on the left and right sides of the hole-opening tube 1, wherein the left plate is provided with a pedal portion 7, and the pedal portion 7 is used for the operator to step on and apply force to improve the hole-opening effect. The pedal portion 7 facilitates the operator to press down the hole-opening tube 1, which is more labor-saving.

[0032] About the driving member. The left side plate is also provided with a fixed block 8, and the driving member includes a pressure rod 9 hinged on the fixed block 8, the pressure rod 9 extends obliquely from bottom to top and passes through the hole-opening tube 1 until it extends to the top of the right side plate, and a through groove 10 for the pressure rod 9 to pass through is correspondingly provided on the side wall of the hole-opening tube 1, and the pressure rod 9 is slidably matched with the auxiliary hole-opening shaft 4 to drive the auxiliary hole-opening shaft 4 downward when the pressure rod 9 is pressed down.

[0033] Specifically, a slider 11 is slidably mounted on the pressure rod 9, and the upper end of the auxiliary hole-opening shaft 4 is hinged on the slider 11. The hole-opening tube 1 also has a guide for the auxiliary hole-opening shaft 4 to pass through, so as to limit the auxiliary hole-opening shaft 4 to only move up and down.

[0034] Regarding the guide member, a horizontally extending partition 12 is arranged inside the hole-opening tube 1, and the partition 12 has a through hole for the auxiliary hole-opening shaft 4 to pass through, and the partition 12 constitutes a guide member.

[0035] In this embodiment, a return spring 13 is provided between the pressure rod 9 and the right side plate to assist the pressure rod 9 in returning to its original position. In other embodiments, the number of the return springs 13 can be adjusted, and can be set to be multiple.

[0036] In addition, the elastic coefficient of the return spring 13 satisfies the requirement of being able to push the pressure rod 9 against the groove wall of the through groove 10 to prevent the pressure rod 9 from shaking when not in use. In this way, the pressure rod 9 can be firmly against the groove wall of the through groove 10 when not in use, and the stability is higher.

[0037] The working principle of the hole-digging device for transplanting tobacco seedlings provided by the utility model is that the operator holds the straight rod 3, presses down the straight rod 3 and steps on the foot pedal 7 to apply downward force to complete the initial hole-digging. When the soil at the hole-digging position is harder, the pressure rod 9 can be further stepped on to move downward, thereby driving the auxiliary hole-digging shaft 4 to move downward further to dig holes and drill holes, thereby enriching the hole-digging means. The whole device has stronger adaptability and is suitable for use in a small range. It is compact and portable and easy to use.
