DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Example
[0026] like Figures 1 to 4 As shown, the weed puller with a plucking head for cleaning of the present invention includes a main rod 1, a plucking head 6 provided at one end of the main rod 1, and an extension rod 5 connected to the main rod 1. Specifically, the main rod 1 is a hollow tube. The plucking head 6 is composed of a main fork 601 and a secondary fork 602. The main fork 601 and the secondary fork 602 both have openings, and the openings of the two are matched, that is, the openings of the main fork 601 and the secondary fork 602 are of the same shape and size, and the openings of the main fork 601 and the secondary fork 602 are in a "U" shape or a "V" shape. In this embodiment, the openings of the main fork 601 and the secondary fork 602 are preferably set to a "V" shape, which is more effective and secure in clamping the grass. In order to clean the weeds and dirt remaining on the plucking head 6, a push plate 10 is provided between the main fork 601 and the auxiliary fork 602. At the same time, an elastic pushing device for pushing the push plate 10 is provided on the main rod 1, so that the push plate 10 can make a straight line reciprocating motion under the action of the elastic pushing device to clean the weeds and dirt remaining on the plucking head 6.
[0027] Among them, a power-assisting arm 7 is provided at the hinge head end of the secondary fork head 602. The power-assisting arm 7 is integrally formed with the secondary fork head 602, and the installation direction of the power-assisting arm 7 is as follows: Figure 5 When in use, the auxiliary fork 602 can be moved upward by the assisting arm 7, and the auxiliary fork 602 forms an upward pulling force on the grass, so that the grass is simultaneously subjected to the thrust of the main fork 601 and the upward pulling force, thereby improving the efficiency of pulling out the grass.
[0028] like Figure 4 As shown, a push rod travel hole is provided on the main fork head 601, which communicates with the main rod 1. A guide tube 15 is provided at the connection between the main rod 1 and the main fork head 601. The hole of this guide tube 15 matches and communicates with the push rod travel hole of the main fork head 601. This is used to limit the travel of the push rod 8, ensuring that the push rod 8 can better maintain linear motion. The push rod 8 passes through the guide tube 15 and the push rod travel hole of the main fork head 601, and then connects to the push plate 10. During installation, the push plate 10 is horizontally fixed to the movable end of the push rod 8 by screws.
[0029] like Figure 3 As shown, the elastic propulsion device includes a spring sleeve 12, a push rod 8, a spring 13, and a sliding sleeve 2. Specifically, the spring sleeve 12 is mounted within the upper end of the main rod 1. It is a tubular sleeve with an open end and a pre-set mounting hole at its bottom. The push rod 8 is positioned within the main rod 1, with one end extending into the spring sleeve 12 through the pre-set mounting hole. The other end passes through the connecting arm of the main fork 601 and is connected to the push plate 10. The spring 13 is mounted on the push rod 8 within the spring sleeve 12. A removable spring fixing screw 14 is provided at the connecting end between the push rod 8 and the spring sleeve 12. The spring 13 is fixed to the spring sleeve 12 via the spring fixing screw 14, i.e., one end of the spring 13 is in close contact with the spring fixing screw 14, and the other end is in close contact with the bottom of the spring sleeve 12. The sliding sleeve 2 is mounted on the main rod 1 and can slide up and down along the rod wall of the main rod 1. The sliding sleeve 2 is connected to the push rod 8 via a pin 11.
[0030] To ensure smooth up-and-down sliding of the sleeve 2 and the pin 11, two strip-shaped through-holes 9 are provided on the main rod 1. These two strip-shaped through-holes 9 are arranged opposite each other and together form a sliding hole. After the pin 11 is connected to the push rod 8, it passes through the two strip-shaped through-holes 9 and is fixed to the sleeve 2. Under the action of the sleeve 2, the pin 11 slides up and down along the wall of the strip-shaped through-hole 9. Driven by the pin 11, the push rod 8 performs a linear reciprocating motion, which in turn causes the push plate 10 to perform a linear reciprocating motion, thereby clearing weeds and dirt from the chuck 6.
[0031] like Figure 2As shown, the extension rod 5 is connected to the main rod 1 via a connecting sleeve 3. Specifically, the connecting sleeve 3 is a hollow tube with pre-threaded inner walls at both ends. The extension rod 5, the main rod 1, and the connecting sleeve 3 are connected by threads. The number of extension rods 5 is two or more, and adjacent extension rods 5 are also connected by the connecting sleeve 3. The number of extension rods 5 can be set according to actual needs. In this embodiment, the number of extension rods 5 is preferably set to two.
[0032] For ease of use, a booster sleeve 4 is sleeved on the extension rod 5 connected to the main rod 1. The booster sleeve 4 is engaged with the sliding sleeve 2 and can slide along with the sliding sleeve 2. When in use, the sliding sleeve 2 can be pushed by pushing the booster sleeve 4, making the pushing of the sliding sleeve 2 more labor-saving and more convenient for the user.
[0033] When the utility model is used, Figure 6 As shown, the pulling head 6 is inserted obliquely into the soil, and the pulling head 6 is pried by the power arm 7. At this time, the grass will be stuck in the openings of the main fork 601 and the auxiliary fork 602 at the same time. When the pulling head 6 is pried, the auxiliary fork 602 will open upward, which simulates the action of pulling out the grass. The grass will be subjected to the thrust of the main fork 601 and the upward pulling force at the same time, so that the grass is quickly pulled up, effectively improving the weeding efficiency of the weed puller.
[0034] When weeds and dirt remain on the plucking head 6, the sliding sleeve 2 is pushed by pushing the assist sleeve 4, and the sliding sleeve 2 drives the pin rod 11 to push the push rod 8 downward. At this time, the push plate 10 located between the main fork head 601 and the auxiliary fork head 602 of the plucking head 6 will push the weeds and dirt remaining on the plucking head 6 away from the plucking head 6 as the push rod 8 moves, thereby achieving self-cleaning of the plucking head 6.
[0035] As described above, the present invention can be well implemented.
