Description
Technical field
The utility model relates to a kind of farm machinery, particularly relates to a kind of air intake duct for filtering earth in Jujube gathering machine.
Background technology
At present, the cultivated area of red jujube tree is about 8,000,000 mu, and the results of red date mainly adopt impact branch, and fruit is landed, then adopt collecting machine to pick up red date.As China Patent No. " 201020641282.0 " disclosed a kind of air aspiration type red date picking machine on 06 22nd, 2011, described collecting machine comprises frame and blower fan that road wheel is housed, frame arranges a Sheng fruit case, the upper front end of containing fruit case is installed with an air intake duct, said assembling is on air intake duct, the free end of air intake duct is connected to a red date picking suction nozzle, a filtration string bag is connected in the rear upper light foreign material expansion chamber lower end of containing fruit case, under the middle top surface of containing fruit case, a gear jujube portion extended straight down is set, the length in gear jujube portion is identical with the width containing fruit case, a Sheng fruit basket is set in the Sheng fruit case below gear jujube portion, contain between the front end top margin of fruit basket and the antetheca containing fruit case and be obliquely installed one piece of red date lower skateboard.Adopt collecting machine to pick up the efficiency of crop that red date significantly can improve red date, and reduce hand labor intensity.But with the prior art that above-mentioned patent document is representative, pick up in jujube process actual, affect by containing negative pressure in fruit case, earth on the ground can enter in case with red date.Although contain in fruit case the lower skateboard be provided with for filtering earth, but because the mud particles sucked is less, lighter in weight, the earth entered after containing fruit case will be crossed lower skateboard and directly fall in Sheng fruit frame under the drive of air-flow, this just causes effectively being separated from red date by earth, and what affect red date picks up quality.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, a kind of air intake duct for filtering earth in Jujube gathering machine is provided, the utility model can filter the earth entering air intake duct in advance, prevent earth from entering and contain in fruit case, thus make the separating effect of earth and red date better.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of air intake duct for filtering earth in Jujube gathering machine, it is characterized in that: comprise outer pvc pipe, interior pvc pipe, for connecting the lower corrugated flexible hose of inhaling jujube head and for being connected the upper corrugated flexible hose containing fruit case, the two ends of described interior pvc pipe are connected with upper corrugated flexible hose and lower corrugated flexible hose respectively, described outer pvc pipe fixed cover is located on interior pvc pipe, and between outer pvc pipe and interior pvc pipe, form airtight earth collecting box, described interior pvc pipe is provided with filter opening, described earth collecting chamber is communicated with outer pvc pipe by filter opening, described outer pvc pipe is provided with open and close type outlet.
Described open and close type outlet is arranged on the link of outer pvc pipe and lower corrugated flexible hose.
Described filter opening is around being opened on the tube wall of interior pvc pipe.
Employing the utility model has the advantage of:
One, in the utility model, can the earth of inhale pipe be filled in earth collecting chamber by the filter opening on interior pvc pipe, the earth entering air intake duct can either be collected by airtight earth collecting chamber, the air pressure in air intake duct can not be affected again, exported the earth can cleared up in earth collecting chamber by open and close type.Adopt the cooperation of said structure, just can filter the earth entering air intake duct in advance, prevent earth from entering and contain in fruit case, thus make the separating effect of earth and red date better.Further, the structure that air intake duct is combined by corrugated flexible hose and pvc pipe, not only makes air intake duct better to the filter effect of earth, also makes whole air intake duct have retractility and advantage easy to use flexibly.
Two, in the utility model, when picking up red date, jujube head and earth surface is inhaled, whole air intake duct is equivalent to be obliquely installed, therefore, open and close type outlet is arranged on the structure of the link of outer pvc pipe and lower corrugated flexible hose, is just conducive to quick collection and the cleaning fast of earth.
Three, in the utility model, described filter opening around being opened on the tube wall of interior pvc pipe, this structure make earth in interior pvc pipe can fast filtering in earth collecting chamber, better to the filter effect of earth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Being labeled as in figure: 1, outer pvc pipe, 2, interior pvc pipe, 3, lower corrugated flexible hose, 4, upper corrugated flexible hose, 5, open and close type outlet.
Embodiment
A kind of air intake duct for filtering earth in Jujube gathering machine, comprise outer pvc pipe 1, interior pvc pipe 2, for connecting the lower corrugated flexible hose 3 of inhaling jujube head and for being connected the upper corrugated flexible hose 4 containing fruit case, the two ends of described interior pvc pipe 2 are connected with upper corrugated flexible hose 4 and lower corrugated flexible hose 3 respectively, described outer pvc pipe 1 fixed cover is located on interior pvc pipe 2, and form airtight earth collecting box between outer pvc pipe 1 and interior pvc pipe 2, described interior pvc pipe 2 is provided with filter opening, described earth collecting chamber is communicated with outer pvc pipe 1 by filter opening, described outer pvc pipe 1 is provided with open and close type outlet 5.
In the utility model, the two ends fixed cover of described outer pvc pipe 1 is located on interior pvc pipe 2, and outer pvc pipe 1 passes through adhering and sealing with the junction of interior pvc pipe 2.
In the utility model, described open and close type outlet 5 is arranged on the link of outer pvc pipe 1 and lower corrugated flexible hose 3, and described open and close type outlet 5 can be opened when clearing up earth, is in closed condition when not clearing up earth.
In the utility model, described filter opening is multiple, and uniform ring is around on the tube wall of interior pvc pipe 2, and the aperture of filter opening is less than the external diameter of red date.
The utility model is when picking up red date, negative pressure is produced in air intake duct, earth enters lower corrugated flexible hose 3 with red date from suction jujube head, enter interior pvc pipe 2 and upper corrugated flexible hose 4 more successively, when red date and earth are through interior pvc pipe 2 this section, earth enters earth collecting chamber by the filter opening on interior pvc pipe 2, when the earth in earth collecting chamber reaches a certain amount of, open the open and close type outlet 5 on outer pvc pipe 1, cleaning earth, and then close open and close type outlet and 5 continue to pick up red date.The utility model can filter the earth entering air intake duct in advance, prevents earth from entering and contains in fruit case, ensures that the separating effect of earth and red date is better.
