Quantitative fertilizer applicator
Technical field
The present invention relates to agricultural machinery technological field, especially a kind of quantitative fertilizer applicator.
Background technology
In soil, apply fertilizer, can supplement the required nutritive element that grows to crop, thus improve the Quality and yield of crop.Existing a kind of fertilizer apparatus comprises material storing box, is horizontally set at the feeding tube of material storing box lower end, the auger conveyor be arranged in feeding tube, drive the motor of augur, the lower end of material storing box is uncovered, feeding tube is communicated with material storing box, in the downside of feeding tube, the position that material storing box lower end is uncovered is provided with discharging opening, there is following deficiency in the fertilizer applicator of this structure: feeding tube easily blocks, and fertilizer of spreading manuer in holes is difficult to quantitative applying.
Summary of the invention
The object of this invention is to provide a kind of quantitative fertilizer applicator, this fertilizer applicator can solve existing fertilizer applicator and easily block the problem being difficult to fertilizing amount quantitatively apply.
In order to solve the problem, the technical solution used in the present invention is: this quantitative fertilizer applicator comprise material storing box, conveying pipeline, by motor-driven auger conveyor, conveying pipeline is communicated with described material storing box, described auger conveyor is arranged in described conveying pipeline, the upper end frame of described material storing box is provided with motor mounting rack, described motor is installed on described motor mounting rack, and the output shaft of described motor is arranged down; Described conveying pipeline is erect and is arranged at described material storing box lower end, and the part that described auger conveyor has helical blade is arranged in described conveying pipeline, and the body of rod of described auger conveyor upwards extends and is connected with described motor; The base plate of described material storing box offers blanking port, on the body of rod of described auger conveyor, the dividing plate abutted against with the base plate of described material storing box is fixed with in described conveying pipeline, described dividing plate offers a material receiving port, described material receiving port is communicated with described material storing box by described blanking port; In described material storing box, be connected with mixing arm on the body of rod of described auger conveyor, the end of described mixing arm has the horizontal segment inconsistent with described base plate.
In the technical scheme of above-mentioned quantitative fertilizer applicator, technical scheme can also be more specifically: described blanking port is up big and down small bellmouth.
Further, the mixing arm that falls described in has the pivotal meander sections of the body of rod around described auger conveyor.
Further, described blanking port is positioned at the turning circle of the horizontal segment of described mixing arm.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: mixing arm can promote the mobility of fertilizer, applies fertilizer smooth and easy, not easily blocks, by being with the division board of material receiving port to control the fertilizer amount entered in conveying pipeline, thus realize quantitative fertilization.
Accompanying drawing explanation
Fig. 1 is the structural representation of this quantitative fertilizer applicator.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Quantitative fertilizer applicator shown in Fig. 1 comprises material storing box 1, motor 2, motor mounting rack 3, mixing arm 4, auger conveyor 5, conveying pipeline 6 and dividing plate 7, motor mounting rack 3 is provided with at the upper end frame of material storing box 1, motor 2 is installed on motor mounting rack 3, and the output shaft of motor 1 is arranged down; Conveying pipeline 6 is erect and is arranged at material storing box 1 lower end, auger conveyor 5 has body of rod 5-1 and is arranged at the helical blade 5-2 of body of rod 5-1 bottom, the part that auger conveyor 5 has helical blade 5-2 is arranged in conveying pipeline 6, and the body of rod 5-1 of auger conveyor 5 upwards extends and is connected with the output shaft of motor 2; On the body of rod 5-1 of auger conveyor 5, mixing arm 4 is connected with in material storing box 1, mixing arm 4 has the pivotal meander sections 4-1 of body of rod 5-1 around auger conveyor 5, the end of mixing arm 4 has the horizontal segment 4-2 inconsistent with the base plate 1-1 of material storing box 1, the base plate 1-1 of material storing box 1 offers the blanking port 1-2 of eccentric setting, blanking port 1-2 is up big and down small bellmouth, and blanking port 1-2 is positioned at the turning circle of the horizontal segment 4-1 of mixing arm 4; In conveying pipeline 6, be fixed with the dividing plate 7 abutted against with the base plate 1-1 of material storing box 1 on the body of rod 5-1 of auger conveyor 5, dividing plate 7 offers a material receiving port 7-1, material receiving port 7-1 is communicated with material storing box 1 by blanking port 1-2.
During use, fertilizer is loaded in material storing box 1, starter motor 2, motor 2 drives auger conveyor 5 to rotate, mixing arm 4 turns round the fertilizer stirred in material storing box 1, to break up the fertilizer of caking, to increase its mobility, simultaneously, dividing plate 7 rotates with auger conveyor 5, when the material receiving port 7-1 on dividing plate 7 go to material storing box 1 blanking port 1-2 be connected time, fertilizer in material storing box 1 enters in conveying pipeline 6 through blanking port 1-2 and material receiving port 7-1, fertilizer is carried downwards along conveying pipeline 6 under the effect of auger conveyor 5, when material receiving port 7-1 and blanking port 1-2 staggers, dividing plate 7 stops that the fertilizer in material storing box 1 enters in conveying pipeline 6, and the fertilizer in conveying pipeline 6 under the rotation of auger conveyor 5 from conveying pipeline 6 lower end discharging, thus realize quantitative fertilization.
