Description

Weeder

Technical field

The utility model relates to gardens, garden weeding apparatus field.

Background technology

At present, field, lawn weeding have specialized apparatus, and weeder is also arranged in the gardens.For example, the weeder that discloses in the patent documentation, application number 03265368.9; Multi-functional grass-remover, application number 200320102684.3; These two kinds of patents are applicable to the weeds that the large tracts of land hoe removes gardens or garden.And trade or specialized apparatus is arranged than weeds, the trade grass Ceng Wei of narrow and small area.Therefore, this weeder is demanded manufacturer urgently and is developed and produce.

Summary of the invention

The utility model will provide a kind of weeder to this area, with the problem that solves present trade or remove than the weeds of narrow and small area.Now in conjunction with the accompanying drawings its feature is described as follows: a kind of weeder, this weeder comprise left and right sides handle, assist handle, upper push-rod, adjusting knob assembly, flexible button, lower push-rod, left and right sides casing, brush wheel, guard shield, roller, roller shaft, worm-wheel bracket assembly, electric machine assembly, worm gear, transmission mechanism; Transmission mechanism is made of worm gear, power transmission shaft, screw, bearing, worm screw, worm-wheel bracket assembly.It is characterized in that left and right sides casing 9 is " moon " font, is provided with transmission mechanism in the casing of the left and right sides; Transmission mechanism branch sleeve, collet, locking nut, thereby locking brush wheel; Roller shaft 13 connects right casing 9, and an end of roller shaft 13 connects roller 12, and roller is the sidepiece that plug-in type is connected right casing, balance and rolling action when playing the weeder operation.Guard shield 10 is connected on the left and right sides casing 9, and left and right sides casing connects lower push-rod 8, and lower push-rod and upper push-rod 5 are connected by needle roller, and the bottom of upper push-rod is provided with the button 6 that stretches, and upper push-rod 5 is connected with left and right sides handle 1.

Described upper end at lower push-rod 8 is provided with locating slot 7, is provided with assist handle 3 in the upper end of upper push-rod 5, and assist handle is provided with adjusting knob assembly 4, and the adjusting knob assembly is held up for weeding work personnel hand or other instrument of interior placement is being provided with.Be provided with switch 2 in the inboard of left and right sides handle 1, connect power line 23 in the end of left and right sides handle.

The worm screw 22 engagement worm gears 16 of described electric machine assembly 15, worm gear connects worm-wheel shaft; Power transmission shaft 18 connects worm screw 22, and worm gear connects worm-wheel shaft, dress brush wheel 11 in worm gear branch sleeve, collet, the locking nut, collet, and brush wheel is respectively equipped with hard brush, soft brush, their width difference.

The structural design of this weeder is comparatively reasonable, good looking appearance, is convenient to dismounting again, the blank of filled up between the trade, the narrow and small area weeds still not having special equipment.The demand that is particularly useful for economically developed national garden resident family, the export trade promise well.

Description of drawings

Fig. 1 is the structural representation of weeder;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the upward view of Fig. 1;

Fig. 4 is the vertical view of Fig. 1.

Fig. 5 is the structural representation of a slice casing about shedding.

Fig. 6 is the transmission mechanism schematic diagram.

Fig. 7 is the structural representation that is connected to the weeder of power line.

The sequence number of above accompanying drawing and title: 1, left and right sides handle, 2, switch, 3, assist handle, 4, the adjusting knob assembly, 5, upper push-rod, 6, flexible button, 7, locating slot, 8, lower push-rod, 9, left and right sides casing, 10, guard shield, 11, brush wheel, 12, roller, 13, roller shaft, 14, the worm-wheel bracket assembly, 15, electric machine assembly, 16, worm gear, 17, gland, 18, power transmission shaft, 19, sealing ring, 20, screw, 21, bearing, 22, worm screw, 23, power line.

Embodiment is an example with the weeder duty.Power line 23 is inserted supply socket, pressing switch 2 power connections, machine operation.The output shaft of motor is connected rotation with power transmission shaft 18, because of the rotating speed of motor height, can not directly be converted to roller shaft 13, can only be by deceleration and the direction conversion of worm screw 22 with worm gear 16, promptly change parallel rotation into by vertical rotation, just realize the slow rotation of roller shaft 13, hoe is cut weeds, and its speed ratio is 13:1.Adjusting knob assembly 4 locking assist handles 3 or unload assist handle and be provided with.When operator's human body height difference, realize that by promoting flexible button 6 in case the boss in the flexible button falls into the locating slot 7 of lower push-rod 8 upper ends, its length has just been set.Because of brush wheel 12 be according to different weeds, highly, width selects to rotate brush wheel, so divide hard brush, as brass wire brush; Soft brush is as the brush of fibrous material compacting etc.Changing brush wheel is the female forward and reverse realization of adopting on the worm-wheel shaft that screws of two caps.
