Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The sweet potato seedling continuous planting mechanism based on the seedling clamp as shown in the attached figure 1 comprises a rack 1 and a rotary table 2, wherein the rotary table 2 is rotatably installed on the rack 1, a bearing is arranged between a rotating shaft of the rotary table 2 and the rack 1 so that the rotary table 2 is reliably connected with the rack 1 and rotates smoothly, and the rotating shaft of the rotary table 2 is horizontally arranged; a plurality of seedling clamps 3 are fixedly arranged on the turntable 2 in a circumferential array; the seedling clamp 3 can clamp sweet potato seedlings; the frame 1 is provided with a control component 4 for controlling the seedling clamp 3 to open and close; when the seedling clamp 3 is within the control range of the control component 4, the seedling clamp is in a closed state; when the seedling clamp 3 is out of the control range of the control component 4, the seedling clamp is in an open state.

Above-mentioned sweet potato seedling planting mechanism is through the carrier of pressing from both sides 3 as the seedling with carousel 2, and it is more reliable that carousel 2 compares in the chain, can not produce the phenomenon that falls chain, card chain like the chain, and stability and reliability improve by a wide margin.

Specifically, as shown in fig. 2, the seedling clamp 3 has a seedling clamp base 31, the seedling clamp base 31 has two clamping portions 32 capable of being opened and closed relatively elastically, and when the two clamping portions 32 are not acted by other external forces, the two clamping portions 32 are opened relatively under the action of elastic force (an elastic element may be disposed between the two clamping portions 32, or an elastic element may be disposed between each clamping portion 32 and the seedling clamp base 31).

As shown in fig. 3, the control assembly 4 comprises two symmetrically arranged holding plates 41, and a gap for the seedling clamp 3 to move in is arranged between the two holding plates 41; when the seedling clamp 3 starts to enter the gap, the seedling clamp is in a horizontal state, the two clamping parts 32 of the seedling clamp are opened upwards, sweet potato seedlings are placed between the two clamping parts 32, a part of the seedling clamp 3 gradually enters the gap along with the rotation of the turntable 2, the two clamping parts 32 are extruded by the two retaining plates 41, so that the two clamping parts 32 are closed, and when the seedling clamp 3 moves in the gap, the two clamping parts 32 of the seedling clamp are respectively extruded by the two retaining plates 41, so that the two clamping parts 32 are always kept in a clamping state, and the sweet potato seedlings clamped between the two clamping parts cannot fall off; when the seedling clamp 3 leaves the gap, the seedling clamp is in a vertical state, one end, far away from the turntable 2, of the seedling clamp 3 is inserted into soil, and under the action of elasticity, the two retaining plates 41 are opened to release the sweet potato seedlings, so that the sweet potato seedlings are vertically remained in the soil, and the planting and transplanting operation of the sweet potato seedlings is completed.

In order to facilitate the switching of the two clamping portions 32 from the relatively open state to the relatively closed state, the upper end of the holding plate 41 is provided with an arc-shaped eversion portion 42, so that the entrance of the gap is in a horn shape gradually narrowing from the width, and thus, the seedling clamp 3 can be gradually closed in the process of entering the gap and cannot be clamped at the entrance of the gap.

In addition, the seedling holder body 31 is in a long strip shape, and has a fixed end fixed on the rotating disc 2, and the rest parts except the fixed end extend out of the rotating disc 2; the length direction of seedling holder body 31 is for the radial slope setting of stiff end mounted position department carousel 2, makes seedling holder body 31 is put and two when clamping part 32 upwards opens, seedling clamp 3 wholly is located 2 direction of height's of carousel upside, and seedling holder body 31 erects the stiff end of seedling holder body 31 and is located 2 direction of height's of carousel downside when putting, so can make the diameter of carousel 2 as little as possible when guaranteeing that seedling clamp 3 has great longitudinal movement distance, keeps overall structure's compactedness, and the user can be in higher position with sweet potato seedling material loading to seedling clamp 3, accords with human engineering. In this embodiment, the included angle between every seedling holder body 31 and the radial of its stiff end position department carousel 2 is 30, and when this angle, the user can feed the seedling to the seedling holder 3 that just has rotated 2 tops of carousel, and the high direction's of carousel utilization ratio is the highest most.

Preferably, as shown in fig. 4, the turntable 2 is connected with a power source through a speed regulating box 5; the input and output speed ratio of the speed regulating box 5 is adjustable. Driving gear and multiunit driven gear are equipped with in the above-mentioned speed governing case 5, adjust the action wheel and the meshing of different group driven gear through dialling the tooth, can change the drive gear and driven gear's drive ratio, so can change speed governing case 5's input/output speed ratio, thereby make under the prerequisite of the equal revolution of power supply input, 2 pivoted revolutions of carousel can change along with the change of input/output speed ratio, so can change sweet potato seedling's planting interval, adjust simply, and current press from both sides 3 with the seedling and install in the scheme on the chain, if will change sweet potato seedling's planting interval, need change the sprocket of chain, the operation degree of difficulty is big.

Preferably, the power source is a land wheel 6, the land wheel 6 is always in contact with the ground and can rotate passively in the moving process of the rack 1, due to the characteristic of passive rotation, the rotational angular displacement of the land wheel 6 strictly corresponds to the moving displacement of the rack 1, and when the land wheel 6 transmits power to the turntable 2 through the speed regulating box 5, the rotational angular displacement of the turntable 2 also strictly corresponds to the moving displacement of the rack 1, so that the planting distance of sweet potato seedlings is always a set value and cannot be changed due to the fast and slow moving speed of the rack 1.

Preferably, carousel 2 passes through ratchet pawl mechanism and connects frame 1 because ratchet pawl mechanism has one-way pivoted attribute, the land wheel can only drive 2 one-way rotations of carousel, and when land wheel antiport, carousel 2 can not follow the reversal, can effectively avoid the seedling to press from both sides 3 damages.

The utility model discloses a sweet potato seedling mechanism of planting in succession based on seedling clamp is through rotating the installation carousel in the frame to press from both sides a plurality of seedlings to be the circumference array and fix on the carousel, make the operation of planting seedling mechanism reliable, can not produce like the conveying chain and take off chain, chain jamming scheduling problem, and fix the seedling clamp on the carousel and also do not have phenomenons such as shake, the fault rate is low, can avoid unnecessary troublesome, the efficiency of promotion operation.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
