Abstract

The utility model relates to a combined type vibrating sieve of an agriculture harvesting machinery. The combined type vibrating sieve comprises a sieve body arranged in a sieve frame. The combined type vibrating sieve is characterized in that a front sieve body is arranged at front part in the sieve frame, the front end of the upper sieve body is connected with the rear end of the front sieve body, the rear sieve body is arranged at the rear lower part of the upper sieve body, a middle sieve body is arranged at the lower part of the upper sieve body, and a lower sieve body is arranged at the lower part of the middle sieve body. Therefore, the phenomenon that the separation effect between the seedling and the soil is bad, and dropped fruits are buried in field is solved. Thus the combined type vibrating sieve ensures the harvesting machinery to have good separation effect of speperating seedling and soil, and to reduce the active effect of harvest loss.

Description

The combined type vibratory sieve

(1) technical field

The utility model relates to a kind of combined type vibratory sieve of agricultural harvesting machinery.

(2) background technology

At present, the vibratory sieve of installing on the harvest machineries such as peanut, medicinal material, garlic, potato only has an aspect, or claims single sieve nest, and the size in gap is consistent on the sieve nest, the peanut harvesting machinery of this Structure of Vibrating Screen pattern, its seedling, native inferior separating effect; The fruit that drops through shaker vibration in the results process (shedding) often by climing the burying in the field of seedling of soil block or band soil, causes unnecessary harvesting loss.

(3) utility model content

The purpose of this utility model is to provide a kind of combined type vibratory sieve, and this combined type vibratory sieve can improve seedling, native separating effect, reduces harvesting loss.

The technical solution of the utility model includes the sieve nest in the screen frame, it is characterized in that anterior in the screen frame is preceding sieve nest, and last sieve nest front end is connecting preceding sieve nest rear end, and back sieve nest is located at the sieve nest rear lower, middle sieve nest is located at the sieve nest bottom, and following sieve nest is located at middle sieve nest bottom.The utility model can make harvest machinery have seedling, native good separating effect, reduces the good effect of harvesting loss.

(4) description of drawings

Fig. 1 is the utility model sieve nest structural representation.

Fig. 2 is the plan structure schematic diagram that Fig. 1 has screen frame.

Among the figure, 5. times sieve nests of sieve nest, 6. rear crank rocking bars, 7. back sieve nest 8. screen frames 9. gratings in the sieve nest 4. on the 1. preceding crank rocker 2. preceding sieve nests 3.

(5) specific embodiment

With reference to the accompanying drawings, the utility model includes the sieve nest in the screen frame (8), it is characterized in that anterior in the screen frame (8) is preceding sieve nest (2), last sieve nest (3) front end is connecting preceding sieve nest (2) rear end, back sieve nest (7) is located at sieve nest (3) rear lower, middle sieve nest (4) is located at sieve nest (3) bottom, and following sieve nest (5) is located at middle sieve nest (4) bottom.So-called sieve nest is meant that the orderly arrangement of grating (9) is certain interval and combines.For harvester for peanut, the gap that sieve nest (2), back sieve nest (7) and following sieve nest (5) are gone up between the grating (9) before of the present utility model is identical, be 10 to 16mm, it is slightly larger that middle sieve nest (4) is gone up between the grating (9) crack, and last sieve nest (3) goes up that the crack is a maximum between the grating (9).For Different Crop, crack difference between the grating on the sieve nest (9).It is bigger than crack between the grating on the harvester for peanut (9) for example to gather in the crops on the combined type vibratory sieve of potato between the grating (9) crack, and the combined type vibratory sieve of results potato also can save middle sieve nest (4), reduces by other screening of level, reaches the results quality equally.Preceding sieve nest (2) is in the rear portion of digger blade on the cropper, sieve nest (2) before last sieve nest (3) front end connects, and the end is in vacant state thereafter.Before sieve nest (2), go up sieve nest (3), middle sieve nest (4), sieve nest (5), back sieve nest (7) all are in the screen frame (8) down, constitute the combined type vibratory sieve through welding.Preceding crank rocker (1), rear crank rocking bar (6) are connecting the forward and backward of screen frame (8).In the operation process, the combined type vibratory sieve is driven by forward and backward crank rocker (1) and (6) and does the front and back oscillating traverse motion, under the effect of crank and rocker mechanism quickreturn characteristics, move on the preceding sieve nest (2) climing by moving behind the forward direction with the crop seedling of soil block and fruit, through preceding sieve nest (2), its major part drops on ground than small clod; Through last sieve nest (3), the soil block that it is bigger and the fruit that comes off are fallen on the middle sieve nest (4), and the climing continuation of seedling of wearing fruit on the last sieve nest (3) moves on the back sieve nest (7) backward, by back sieve nest (7) being placed in the field with climing the embarking on journey of the seedling of fruit; Soil block on the middle sieve nest (4) and part shedding screening are fallen down on the sieve nest (5) than small clod and than the fruitlet sieve after outlet is dropped in the field; Through being collected into the rear portion or the field of dropping after sieve nest (5) screening down.The combined type vibratory sieve of this sizing screening is compared with the vibratory sieve of existing single aspect sieve nest, and the one, increased and separated the vibration area, seedling soil good separating effect; The 2nd, the screening process classification is carried out, different time drops in different regions, has solved the phenomenon that shedding is embedded in the field.Therefore, the utility model can make harvest machinery have seedling, native good separating effect, reduces the good effect of harvesting loss.

Claims

1. combined type vibratory sieve, include the sieve nest in the screen frame (8), it is characterized in that anterior in the screen frame (8) is preceding sieve nest (2), last sieve nest (3) front end is connecting preceding sieve nest (2) rear end, back sieve nest (7) is located at sieve nest (3) rear lower, middle sieve nest (4) is located at sieve nest (3) bottom, and following sieve nest (5) is located at middle sieve nest (4) bottom.

2. combined type vibratory sieve according to claim 1 is characterized in that the described rearward end that goes up sieve nest (3) is a vacant state.
