Yet these excavation tools all have certain shortcoming, as can not eradicate weeds, or can leave bigger pit on the ground after removing weeds, destroy original turf, thereby cause greater damage to lawn
[0003] At the same time, the structure of the hand-holding part of the existing excavating tools is not designed in conjunction with the characteristics of the weeding machine when it is working, and it does not combine the weeding work with the application of ergonomics. The length is long and the structure is not compact, causing the operator to operate Inconvenient, time-consuming and laborious

Embodiment 1

[0023] Such as figure 1 , figure 2 As shown, the electric weeder includes a main casing 7, and a driving device is arranged in the main casing 7. The driving device drives the transmission shaft to rotate, and the transmission shaft is connected with the working head, and the transmission shaft drives the working head to rotate. The working head is bolts 1 distributed on the same circumference, generally there are multiple bolts 1, and one end of the bolts 1 is connected to the transmission shaft. A push handle 5 that can move axially along the transmission shaft is provided outside the transmission shaft.

[0024] (1) The optimal length of the shape of the electric weeder:

[0025] 1. The length L1 range of the grip part of the main casing 7 of the electric weeder: 50<L1≤170 mm, so that when the operator holds the handle, there is room for fingers;

[0026] 2. Range of length L2 of push handle 5: 60

Embodiment 2

[0036] Such as image 3 , Figure 4 As shown, the main casing 7 of the electric weeder is provided with a driving device (not shown in the figure), the driving device drives the transmission shaft 2 to rotate, and the lower end of the main casing 7 is connected to a sleeve 8 outside the transmission shaft 2. In other embodiments, the sleeve 8 can also be integrated with the main casing 7 . One end of the sleeve 8 is connected to the main casing 7, and the other end is a barrel rim 81 protruding from the barrel. The working head is bolts 1 distributed on the same circumference, generally there are multiple bolts 1, and one end of the bolts 1 is connected to the transmission shaft 2. The driving device can be an electric drill, an electric screwdriver or other electric driving devices.

[0037] A push-off handle 5 that can slide axially along the drive shaft 2 is arranged on the periphery of the transmission shaft 2. The push-off handle 5 is cylindrical, and one end is a barr...

Embodiment 3

[0043] Such as Figure 5 , Figure 6 Shown, improved on the basis of embodiment 2.

[0044]The baffle plate 3 in this embodiment is movably connected with the push handle 5, and the outer edge of the baffle plate 3 is provided with a circle of convex edges 31, and the end of the push handle 5 is correspondingly provided with a circle of grooves 53 for accommodating the convex edges 31 of the baffle plate 3, so that The baffle plate 3 can rotate freely in the push handle 5 . When the push handle 5 slides up and down in the axial direction, it can also drive the baffle plate 3 to slide together. The structure of the sleeve 8 in the first embodiment is changed. A sleeve 9 outside the rotating shaft 2 is connected to the lower end of the main housing 7 . In other embodiments, the sleeve 9 can also be integrated with the main housing 7 . One end of the sleeve 9 is connected to the main housing 7 , and the other end is connected to a spring limiting block 10 protruding outward. ...

Abstract

The invention discloses an electric weeding machine. The electric weeding machine comprises a driving device, a transmission shaft and a working head, wherein the driving device is arranged in a shell, the transmission shaft is driven to rotate by the driving device, and the working head is connected with a transmission device and axially rotates along with the transmission device; and the electric weeding machine is characterized in that: the electric weeding machine is provided with a push unloading device, wherein the length L2 of the push unloading device is more than 60 mm and no more than 200 mm, and the total length L0 of the whole machine body is more than 125 mm and no more than 400 mm. According to the electric weeding machine disclosed by the invention, the automatic weeding operation can be achieved by only using a push unloading handle, the overall structure is simpler, and the length of the overall mechanism is efficiently reduced, so that the electric weeding machine ismore lightweight and portable and more laborsaving by handholding; and compared with other machines, the design and shape of a morphological structure are more fit with the ergonomics, an operator can save labor and time during operation and difficultly feel fatigue by handholding, therefore, the efficiency of weeding is efficiently increased.

Description

technical field [0001] The invention relates to an electric tool for removing weeds in a lawn in gardens, in particular to a weeder. Background technique [0002] The traditional methods of removing lawn weeds mainly include manual weeding and chemical spraying of herbicides. In order to reduce the labor intensity of manual weeding and improve the efficiency of weeding, some digging tools for weeding have been designed, including manual machines and hand-held electric weeding machines. Yet all there is certain shortcoming in these excavating tools, as can not eradicate weeds, or can leave bigger earth pit on the ground after removing weeds, destroy original turf, thereby cause bigger damage to lawn. [0003] At the same time, the structure of the hand-holding part of the existing excavating tools is not designed in conjunction with the characteristics of the weeding machine when it is working, and it does not combine the weeding work with the application of ergonomics. The l...
