The specific implementation provides a seedling and weed picking device which can pull out weeds in a root-by-root manner and can prevent the weeds from scratching workers when the weeds are pulled out.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Referring to fig. 1-4, an embodiment of the present invention provides a seedling picking and weeding device, which includes a main body 1 and a root picking device. The main body 1 may be a round bar structure for holding by a person, and the first end of the main body 1 is a hollow structure with an opening, although the main body 1 may also be a hollow tube. Wherein, get a root device and include inserted sheet 2, connecting rod 3, guide pillar 4 and bracing piece 5. Referring to fig. 1, the number of the blades 2 is at least two, and a first end of each blade 2 is pointed to enable insertion into soil, and a second end of each blade 2 is hingedly connected to the body 1. Preferably, the respective tabs 2 are evenly distributed along the circumference of the body 1. Alternatively, the number of blades 2 is four. The quantity of connecting rod 3 is the same with the quantity of inserted sheet 2 to connecting rod 3 is the one-to-one correspondence with inserted sheet 2, and each connecting rod 3 equal one end is articulated with corresponding inserted sheet 2, and the other end is connected with guide pillar 4, and wherein connecting rod 3 should be located one side that is close to the main part 1 center on inserted sheet 2 with the articulated position of inserted sheet 2. The guide post 4 is sleeved inside the main body 1. The quantity of bracing piece 5 is two at least, and the first end and the guide pillar 4 of each bracing piece 5 are connected, and the second end stretches out the all side walls of main part 1, and the second end of each bracing piece 5 all extends towards the direction that is close to inserted sheet 2. An avoidance groove 6 through which the support bar 5 passes is provided on the circumferential side wall of the main body 1 at a position corresponding to each support bar 5, and the avoidance groove 6 extends in the axial direction of the guide post 4.

During the use, aim at ruderal root with main part 1 center and insert, inserted sheet 2 gets into soil, bracing piece 5 and ground contact afterwards, insert 2 along with continuing to insert in soil, bracing piece 5 receives the holding power on ground and upwards moves for main part 1 to drive guide pillar 4 also upwards displacement for main part 1, guide pillar 4 pulling connecting rod 3, connecting rod 3 pulling inserted sheet 2, make each inserted sheet 2 all draw close to the direction of main part 1 center, until each inserted sheet 2 offsets with adjacent inserted sheet 2, it can pull out weeds with the root afterwards to pull up main part 1. So set up, on the one hand can extract the plant with the root, prevents that weeds from following remaining root regeneration, improves the weeding effect, and on the other hand, the user need not to go to weeds with the hand to can avoid weeds to draw the people of hindering, of course the utility model provides a pick seedling and pull out the grass ware not only can be used for pulling out weeds, can also be used for the operation of picking out the seedling of crops.

Referring to fig. 1, in some embodiments, the seedling picking and weeding device further comprises a support ring 7, the second end of each support rod 5 is fixedly connected with the support ring 7, for example, welded, and each insert 2 is located in the annular space of the support ring 7. Through setting up support ring 7, can increase the area of contact on bracing piece 5 and ground, insert subaerial when preventing bracing piece 5 and ground contact, ground can support bracing piece 5 more steadily, makes inserted sheet 2 can be closed better to take out weeds and grass roots.

In some embodiments, when the support bar 5 abuts against the wall of the avoiding groove 6 on the side close to the inserting sheet 2, the inserting sheet 2 is opened away from the center of the main body 1, for example, the opening angle of the inserting sheet 2 may be 5-10 °. When soil is harder, inserted sheet 2 enters into soil in, soil can produce great resistance to inserted sheet 2, easily leads to inserted sheet 2 automatic closure, leads to the herbicidal root effect to descend. According to the arrangement in the embodiment, the inserting pieces 2 are slightly opened outwards, when the inserting pieces 2 are inserted into soil, the resistance of the soil to the inserting pieces 2 tends to further open the inserting pieces 2, the inserting pieces 2 cannot be closed, and the supporting rod 5 is abutted against the groove wall of the avoiding groove 6 and cannot move downwards, so that the inserting pieces 2 cannot be further opened, and the inserting pieces 2 can be smoothly inserted into the soil.

Of course, in order to prevent the inserting sheet 2 from being automatically closed in the inserting process, other modes can be adopted, as shown in fig. 4, in other embodiments, the seedling and grass picking device further comprises a second locking mechanism for preventing the guide post 4 from moving upwards, and in the process that the inserting sheet 2 is inserted into soil, the inserting sheet 2 can be prevented from being closed by avoiding the guide post 4 from moving upwards. The second locking mechanism comprises a second sliding rod 15, a third guide sleeve 16, a second connecting rod 17, a second operating rod 18 and a fourth guide sleeve 19.
