suction weeder

Abstract

The invention provides a suction weeder comprising a box provided with an inner cavity. A suction pump is connected to the rear of the cavity. A pipe is communicated to the front of the cavity. A grass collection bag is communicated to the bottom of the cavity. The inside of the cavity is provided with a filter mesh plate behind the grass collection bag and in front of the suction pump. An intake connector is connected to the front end of the pipe and is provided with a rotary shaft inside, wherein the rotary shaft is parallel to the intake direction of fan blades. The edge of each fan blade is sharp. The suction weeder is flexibly applicable to various complex conditions and has excellent weeding effect especially for weeds in croplands.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a weeder. Background technique [0002] In the fields of agriculture and garden maintenance, the weeder is a commonly used machine; for the current weeder, blades are used to cut weeds, and for automatic weeder, the blades need to be driven by motors. For this, a The blade of one type of weeder is directly connected to the drive shaft of the motor, which makes the position of the blade of the weeder bulky; the other type of weeder uses a drive link to indirectly connect to the motor shaft. Due to the long path of the moving parts and complex structure, this type of weeder Therefore, it is easy to be damaged; in addition, for the aforementioned weeding machines, the cutter head is in direct contact with the weeds, and the position of the cutter head cannot be changed at will, so it cannot be flexibly weeded according to various working conditions, and the application range is...

[0002] In the fields of agriculture and garden maintenance, the weeder is a commonly used machine; for the current weeder, blades are used to cut weeds, and for automatic weeder, the blades need to be driven by motors. For this, a The blade of one type of weeder is directly connected to the drive shaft of the motor, which makes the position of the blade of the weeder bulky; the other type of weeder uses a drive link to indirectly connect to the motor shaft. Due to the long path of the moving parts and complex structure, this type of weeder Therefore, it is easy to be damaged; in addition, for the aforementioned weeding machines, the cutter head is in direct contact with the weeds, and the position of the cutter head cannot be changed at will, so it cannot be flexibly weeded according to various working conditions, and the application range is very wide. limited; especially, in the field of common weeding in farmland, since the stalks of weeds and the stalks of crops grow almost side by side, in this case, the aforementioned first type of weeding machine cannot enter the crop field at all, and the second type Since the blade of the weeder directly contacts the weed stalks and cuts them, it must also touch the crop stalks and cut off the crops together; it can be seen that the current weeder for the weeds in the crop field, almost powerless
