Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of field tobacco planting, in particular to a tobacco ridge body weeding device. Background Art
[0002] Intertillage is an important part of tobacco field management, which aims to till the soil between tobacco ridges, weed and build up the soil on the tobacco ridges, improving soil permeability while ensuring the full development of tobacco plant roots and nutrient supply. However, existing intertillage equipment is more focused on building up the soil, and it is difficult to effectively remove the weeds growing on the ridges, so tobacco farmers often need to spray pesticides or physically weed the ridges again later. Utility Model Content
[0003] The utility model aims to provide a tobacco ridge body weeding device. The utility model improves the existing tillage equipment and realizes the cleaning of weeds on the tobacco ridge body on the basis of soil rotary tillage.
[0004] To achieve the above object, the present invention provides the following technical solutions:
[0005] A tobacco ridge weeding device comprises a knife unit frame of a cultivator, on which a spray assembly and a ridge scraping assembly are arranged: the ridge scraping assembly comprises a mounting block fixed at the top surface of the end of the knife unit frame, both ends of the mounting block in the horizontal direction are respectively connected with limit blocks fixed on the knife unit frame by connecting rods, a sliding block is slidably provided on the connecting rod, and a spring is sleeved on the connecting rod body of the sliding block and the mounting block, and the bottom of the sliding block passes through a preset slide on the knife unit frame and is connected to the top of an inclined scraping plate.
[0006] Preferably, the spray assembly includes a liquid medicine tank arranged on the knife group frame, the liquid inlet of the water pump is connected to the liquid medicine tank, and the water outlet is connected to the connecting pipe, both ends of the connecting pipe are closed and connected to the bottom surface of the knife group frame through mounting plates respectively, and the bottom surface of the connecting pipe is connected to several nozzle pipes.
[0007] Preferably, the bottoms of the two mounting plates are also connected via an arc-shaped protective net, and the arc-shaped protective net covers the outside of the connecting pipe.
[0008] Preferably, the nozzle pipe is a variable diameter tube with an outer diameter increasing from top to bottom, the top of the nozzle pipe is connected to a preset through hole on the bottom surface of the connecting pipe through a hose, and the bottom end of the nozzle pipe passes through the arc-shaped protective net and is flush with the bottom surface of the arc-shaped protective net.
[0009] Preferably, the two scraping plates are inclined with the tops facing away from each other and the bottoms facing each other, and two sets of mutually socketed mounting tubes and adjusting rods are provided between the two scraping plates. Several pushing shovels are provided on the outer walls of the mounting tubes, and the pushing shovels on the two mounting tubes are staggered with each other.
[0010] Preferably, the outer wall of the scraping plate facing the chimney is provided with a first hanging rod and a second hanging rod, the first hanging rod is arranged close to the working direction and the length of the first hanging rod is smaller than the second hanging rod.
[0011] The working process of this utility model is as follows:
[0012] First, the rotary tiller is started and the utility model is moved in the furrow. The rotary tiller uses its own knife group to stir and break the land, and at the same time, the water pump is turned on. The water pump pumps the herbicide in the liquid tank into the connecting pipe, passes through the through hole-hose-sprinkler pipe, and then sprays it on the soil treated by the knife group, so that the herbicide can fully contact the soil and weeds. The water pump is preferably a sewage pump. Since the herbicide is usually prepared by granular medicine, the sewage pump can effectively discharge the solid-liquid mixture, avoiding the situation where the traditional water pump is blocked by solid deposition in the herbicide.
[0013] At the same time, the utility model is provided with an arc-shaped protective net and designs the shape of the nozzle pipe to be a trumpet shape with a large upper part and a small lower part, which can prevent the soil from splashing and hitting the connecting pipe and clogging the nozzle pipe when the knife group stirs the soil.
[0014] As the rotary tiller moves, the subsequently moving dozer can till the soil sprayed with herbicides again. On the one hand, it can make the soil and herbicide mixed more evenly, allowing the herbicide to contact the weeds buried in the soil, improving the effectiveness of the herbicide and avoiding the situation where most of the traditional sprayed herbicides remain on the soil surface, resulting in poor weed control effects. On the other hand, it can break up large clods of soil again, and at the same time, it can scrape out some larger weeds and eventually bring them to the edge of the field.
[0015] At the same time, under the action of the spring, the slider is forced to drive the scraping plates to move away from each other, so that the contact surface of the scraping plates can contact the sides of the ridge bodies on both sides. On the one hand, the first hanging rod and the second hanging rod are used to uproot the weeds on the ridge body. On the other hand, the hanging rod can be used to loosen the soil on the surface of the ridge body on the basis of forcing the ridge body to prevent the ridge body from falling.
[0016] Compared with the prior art, the utility model has the following advantages: the utility model improves the existing tillage equipment, realizes the cleaning of weeds on the ridge body on the basis of soil rotary tillage, and also optimizes the spraying operation of ridge ditch weeds and improves the spraying effect.
