Description

Technical Field

[0001] The invention relates to the field of rice transplanting devices, in particular to a rice seedling planting device for planting. Background Art

[0002] Rice is a species of herbaceous rice in the genus Oryza and the most important and oldest species as a grain in the genus. It is also called Asian cultivated rice, or simply rice. Rice is native to China and is one of the world's major food crops. China's rice planting area accounts for a quarter of the country's food crops, and its output accounts for more than half. It has a cultivation history of 14,000 to 18,000 years and is an important food crop. In addition to edible caryopsis, it can be used to make starch, brew wine, and make vinegar. Rice bran can be used to make sugar, press oil, and extract furfural for industrial and medical use. Rice stalks are good feed and raw materials for papermaking and weaving materials. Rice sprouts and rice roots can be used for medicinal purposes. The fruit of rice is paddy grain, which is called rice or rice after shelling. Nearly half of the world's population, including almost the entire population of East Asia and Southeast Asia, feeds on rice.

[0003] The existing rice planting equipment has the following technical problems: it is difficult to control the clamping force when sowing with a clamping sowing mechanism similar to a manipulator, so that when planting, some fragile seedlings will be clamped on the sides, resulting in the survival rate of the seedlings always failing to reach the desired result. The number of survival seedlings needs to be supplemented by the amount of seedlings, resulting in a waste of some economic resources. In addition, when inserting the seedlings into the mud, the traditional clamping sowing mechanism needs to pull out the clamping mechanism, and when pulling it out, the already planted seedlings will be brought out a certain distance again, causing the seedlings to fall over or the survival rate to decrease in the later stage.

[0004] Application No. 201822189697.8 discloses a rice planting device, including a walking mechanism, a frame, a seedling tray arranged on the frame, and a seeder arranged immediately behind the seedling tray, wherein the seedling tray is arranged obliquely at the rear of the frame, and the lower edge of the seedling tray is in an arc shape, and the seeder includes a frame, a seeding tray assembly arranged on the frame, and a driving motor, wherein the seeding tray is composed of two circular clamps arranged symmetrically, and a rotating shaft is coaxially arranged in the middle of the circular clamps, and the ends of the rotating shafts on the two circular clamps are connected by a universal joint transmission, and the power output shaft of the driving motor is connected to the rotating shaft transmission, and an angle is formed between the axial directions of the rotating shafts of the two circular clamps so that the two circular clamps are fitted to each other at a position close to the lower edge of the seedling tray and separated from each other at a position away from the lower edge of the seedling tray. The rice planting device of the utility model can ensure the sowing depth of the seedlings and can significantly expand the sowing width.

[0005] In this solution, a clamping disc is used to plant the seedlings into the soil. However, after the speed is increased, the backward rotation of the clamping disc will still bring the seedlings out of the soil, or the planted seedlings will be tilted and cannot stand upright.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The rice seedling planting device is provided with a transplanting assembly and a linkage assembly. A sprocket is connected to an external power to make a rocker arm swing. When the rocker arm swings, the arc-shaped rocker arm and the pointed cone are prompted to pass between two arc-shaped tracks. Due to the effect of the arc-shaped track, the roller will fit the inner side of the arc-shaped track. Therefore, after the two pointed cones enter the vertical groove, they will be closed by the effect of the arc-shaped track. The two pointed cones can grab a part of the seedlings and move downward, so as to bring the seedlings out of the vertical groove. Since the pointed cones enter the seedling box in an arc shape, and the inner side of the pointed cones is provided with an arc-shaped groove and a clamping claw, the pointed cones will not damage the seedlings when bringing them out. Moreover, the vertical groove has a certain size, which is much larger than the diameter of the seedlings. When the seedlings are moved out from the bottom of the vertical groove, the roots will not be damaged, thereby achieving a high survival rate of transplanted seedlings.

[0028] 2. The rice seedling planting device is provided with a transplanting assembly and a linkage assembly. When the pointed cone is inserted longitudinally downward into the soil, the protrusion on the control wheel A will move the protrusion on the control wheel B. At this time, the hinge will pull the arc track, causing the arc track to leave the roller. At this time, due to the reaction force of the spring A, the two pointed cones will separate. The separation action is performed after the seedling is inserted into the soil, and the rocker arm returns to its original position. When the pointed cone is brought out, it will immediately leave the seedling and will not bring the seedling out of the soil again.

[0029] 3. The rice seedling planting device is provided with a rocker arm and an angle adjustment rod. The angle between the angle adjustment rod and the rocker arm can be changed. By adjusting the angle, the pointed cone can be inserted into the soil each time according to the transplanting depth. When the depth is in place, the pointed cone is in a longitudinal state, thereby preventing the seedlings from lodging when transplanting.

[0030] 4. The rice seedling planting device is provided with a seedling box, which is tilted so that the seedlings can gradually slide to the vertical groove position. Since one end of the seedling box is an arc structure, the seedlings will be gathered and the seedlings will not fall or be blocked.

[0031] 5. The rice seedling planting device is provided with a vibration component, which will cause the seedling box to shake when the machine is running. When the seedling box shakes, the seedlings can be moved to the vertical groove more smoothly without causing blockage. BRIEF DESCRIPTION OF THE DRAWINGS

The seedling boxes 101 are installed on a traditional transplanting vehicle according to the vibration component 2. The seedling boxes 101 are arranged in cooperation with the traditional transplanting vehicle, and the seedlings carried on the traditional transplanting vehicle can be placed in the seedling boxes 101. The power component 4 and the seedling box 101 are installed in equal amounts, and the rotating shafts 402 of the plurality of power components 4 can be connected as one. The sprocket 406 is powered by the vehicle body, and the sprocket 406 needs to provide a reciprocating swinging force without rotating. The swinging force can be provided by most agricultural machinery in the prior art, and the power element can also be customized according to the existing agricultural machinery technology.

[0055] The rice transplanting assembly 3 includes a rocker arm 301 and an angle adjustment rod 302. Two rocker arms 301 and two angle adjustment rods 302 are provided. One end of the two rocker arms 301 is fixed to the rotating shaft 402, and the angle adjustment rod 302 is connected to the rocker arm 301.

[0056] It also includes an arc-shaped swing arm 303, which is provided with two, and is respectively hinged to one end of the two angle adjustment rods 302 away from the rocker arm 301, and a follower rod 304 is fixed at the hinge position between the arc-shaped swing arm 303 and the angle adjustment rod 302, and a large arm 305 is fixed to one end of the two follower rods 304, and a small arm 306 is fixed to the other end, and a spring A307 is provided between the ends of the two large arms 305 away from the follower rod 304, and the two ends of the spring A307 are respectively fixed to the two large arms 305, and the ends of the two small arms 306 away from the follower rod 304 are installed with a rotatable roller 308;

[0057] It also includes a pointed cone 309, two of which are respectively fixed to one end of the two arc-shaped swing arms 303 away from the angle adjustment rod 302, and one end of the pointed cone 309 away from the arc-shaped swing arm 303 is a pointed end structure;

[0058] When the rocker arm 301 rotates along the rotating shaft 402 , the two pointed cones 309 can be moved into the vertical slot 102 .

[0059] When the spring A307 is not subjected to force, the two pointed cones 309 are in a separated state. When the two pointed cones 309 are in a separated state, they can still pass through the vertical slot 102 .

[0060] The linkage assembly 5 includes an arc track 501, and two arc tracks 501 are provided. The two arc tracks 501 are respectively located on both sides of the vertical groove 102; a diffusion bar 502 is fixed to the upper end of each arc track 501, and when the pointed cone 309 is located between the two arc tracks 501, the two rollers 308 are located between the two arc tracks 501 and slide in close contact with the arc tracks 501;

[0061] Two elastic hinges 503 are installed on any arc track 501, and the other end of the elastic hinge 503 is connected to the seedling box 101. The elastic hinge 503 is used for the arc track 501 to move horizontally relative to the seedling box 101;

[0062] It includes an auxiliary shaft B504, two auxiliary shafts B504 are provided, corresponding to the two arc tracks 501 respectively, the auxiliary shaft B504 is fixed to the connection point of one of the elastic hinges 503 and the seedling box 101, and the auxiliary shaft B504 is installed with a control wheel B505;

[0063] The control wheel B505 is located at one side of the control wheel A405. When the rocker arm 301 drives the pointed cone 309 to rotate to the bottom, the rotating shaft 402 drives the control wheel A405 to rotate through the chain 404 and pushes the control wheel B505 to rotate, so that the arc track 501 leaves the roller 308.

[0064] The arc track 501 is a metal strip, and the distance between the two arc tracks 501 is fixed. The diffusion strip 502 is in the shape of a trumpet opening, which is convenient for the roller 308 to enter between the two arc tracks 501 from above. The elastic hinge 503 is a V-shaped structure with hinge points at both ends. A torsion spring is installed at the hinge of the V end, and a torsion spring is also installed at the hinge with the seedling box 101. The torsion spring has a large elastic coefficient and is not affected by the roller 308. When the torsion spring is not under force, it ensures that the arc track 501 does not shake.

[0065] The two cones 309 are each provided with an arc groove 310 on the side close to each other. The arc groove 310 extends from the top to the tip of the cone 309 and the diameter gradually decreases. Two claws 311 are fixedly installed at the tip of the cone 309, and the claws 311 are all arc-shaped structures.

[0066] The arc groove 310 can adapt to the shape of the seedling plant from large to small, and will not pinch the seedling. The pointed cone 309 will separate the seedlings when inserted into the seedling cluster, and the claw 311 has the effect of grabbing the bottom of the plant to prevent it from falling.

[0067] The outer circumference of the control wheel A405 and the control wheel B505 are both provided with a protrusion, which can transmit power when the protrusions are in contact.

[0068] The two angle adjustment rods 302 are located between the two rocker arms 301 . Stud bolts are installed on the rocker arms 301 . The angle adjustment rods 302 are sleeved on the stud bolts and fastened with nuts.

[0069] The vibration assembly 2 includes a spring B201 and a mounting plate 202 . Two springs B201 are provided, one end of which is fixed to the seedling box 101 , and the other end of which is fixed to the mounting plate 202 .

[0070] When the mounting plate 202 is mounted on the vehicle body, the vibration of the vehicle body can be buffered by the spring B201, and the seedling box 101 can also be made to shake slightly to prevent the seedlings from being blocked.

[0071] When in use, the mounting plate 202 is installed on the machine, and the vibration component 2 will cause the seedling box 101 to shake when the machine is running. When the seedling box 101 shakes, the seedlings can be moved to the vertical groove 102 more smoothly. The seedling box 101 is tilted, so that the seedlings can gradually slide to the vertical groove 102. Since one end of the seedling box 101 is an arc structure, the seedlings will be gathered, and the seedlings will not fall over or get blocked. The sprocket 406 is connected to an external power source to enable the rocker arm When the swing arm 301 swings, the arc swing arm 303 and the pointed cone 309 will pass between the two arc tracks 501. Due to the action of the arc track 501, the roller 308 will fit the inner side of the arc track 501. Therefore, after the two pointed cones 309 enter the vertical groove 102, they will be closed by the action of the arc track 501. The two pointed cones 309 can grab a part of the seedlings and move downward, and can take the seedlings out of the vertical groove 102. When the pointed cones 309 are inserted vertically downward When the seedlings are inserted into the soil, the protrusion on the control wheel A405 will move the protrusion on the control wheel B505. At this time, the hinge will pull the arc track 501, causing the arc track 501 to leave the roller 308. At this time, due to the reaction force of the spring A307, the two sharp cones 309 will separate. The separation action is performed after the seedlings are inserted into the soil, and the rocker arm 301 returns to its original position. When the sharp cones 309 are taken out, they will immediately leave the seedlings and will not take the seedlings out of the soil again. The arc track 501 leaves the roller The wheel 308 will then be returned by the elastic force, but at this time the roller 308 is outside the arc track 501. When the roller 308 moves to the position of the diffusion strip 502 of the arc track 501, it can re-enter the arc track 501. The angle between the angle adjustment rod 302 and the rocker arm 301 can be changed. By adjusting the angle, it can be ensured that the pointed cone 309 is inserted into the soil each time according to the transplanting depth. When the depth is in place, the pointed cone 309 is in a longitudinal state, thereby preventing the seedlings from falling over when transplanting.
