Through twice sieving, the silt contained in the waste mulching film is basically sieved out, the obstruction between the waste mulching film and the blade on the cutter is further reduced, and therefore the qualification rate of plastic fragments is improved. The mode of transferring the waste mulching films after primary sieving to the second vibrating screen 52 is various, for example, a common mechanical arm is used for grabbing the waste mulching films after primary sieving, and the waste mulching films are transferred to the second vibrating screen 52 for secondary sieving, and the mechanical arm can be arranged on the first vibrating screen 51 or the second vibrating screen 52.
Referring to fig. 4, the feeding mechanism 4 in the above embodiment includes a supporting frame 41, and a first fixing member 411 and a second fixing member 412 disposed on the supporting frame 41; the first fixed part 411 is connected with the first vibrating screen 51, and the second fixed part 412 is connected with the second vibrating screen 52; the second vibrating screen 52 is provided with a mechanical arm 42, and the mechanical arm 42 can be arranged on the second vibrating screen 52 and also can be arranged on the first vibrating screen; the mechanical arm 42 can transfer the waste mulching films on the first vibrating screen 51 to the second vibrating screen 52, and can also fill the waste mulching films on the second vibrating screen 52 into the feed hopper 11. When the 5 vibrations screening unit that promote unit 3 set up on with feed mechanism 4 promoted to feeder hopper 11 like this, arm 42 just can snatch the old and useless plastic film that passes through the secondary and sieve on the second reciprocating sieve 52 to in filling the feeder hopper with old and useless plastic film, avoided the cost that manual operation brought to improve.
In order to realize the automatic feeding of the feeding mechanism, please refer to fig. 5, the feeding mechanism of the above embodiment includes a height measuring instrument and a control unit connected to the height measuring instrument; the height measuring instrument is used for measuring the height difference between the second vibrating screen and the inlet of the feed hopper; the control unit is used for controlling the mechanical arm 42 to fill the waste mulching films on the second vibrating screen 52 into the feed hopper 11 when the height difference between the second vibrating screen and the inlet of the feed hopper is 0. Because height measurement appearance and the control unit have been added at feed mechanism for the control unit can receive the difference in height information between the entry of second reciprocating sieve and feeder hopper that height measurement appearance sent in real time, and when the difference in height between the entry of second reciprocating sieve and feeder hopper was 0, control unit can control arm 42 and fill into feeder hopper 11 with the old and useless plastic film on the second reciprocating sieve, has realized the automation of feeding.
As for the mesh aperture of well first reciprocating sieve 51 and the mesh aperture of second reciprocating sieve 52 in the above-mentioned embodiment specifically can be according to big-first little principle, and the mesh aperture of first reciprocating sieve 51 is than the mesh aperture of second reciprocating sieve 52 greatly promptly, just can sieve away the great silt of particle diameter in the old and useless plastic film like this when once sieving, and then follow-up when sieving for a second time, can sieve away the less silt of particle diameter in the old and useless plastic film, realize that the old and useless plastic film sieves in grades. For example, the first vibrating screen 51 may be defined to have a mesh size of 10mm to 30mm, and the second vibrating screen 52 may be defined to have a mesh size of 1mm to 10mm, but not limited thereto.
In addition, in order to better understand whether the particle diameter of the plastic fragments that obtain after the old and useless plastic film is torn up is qualified, can carry out following two kinds of settings to the structure of discharge gate department, wherein the qualification rate of plastic fragments can be guaranteed to arbitrary homoenergetic.
The first method comprises the following steps: referring to fig. 6, a sampling hole for sampling and detecting plastic fragments is formed on the discharge port 12; therefore, the operator can sample and detect the plastic fragments at any time in the working process so as to judge whether the granularity of the plastic fragments is qualified. In addition, in order to improve the qualified rate of the plastic fragments, the discharge port 12 is respectively connected with the discharge pipeline 6 and the conveying pipeline 7 for conveying the plastic fragments at the discharge port 12 to the feed hopper 11, a first valve 60 is arranged at one end of the discharge pipeline 6 opposite to the discharge port 12, and a second valve 70 is arranged at one end of the conveying pipeline 7 opposite to the discharge port; if the particle size of the plastic fragments is detected to be unqualified, the unqualified plastic fragments can be shredded again by closing the first valve 60 and opening the second valve 70 to return to the feed hopper 11 through the conveying pipeline 7; if qualified, the second valve 70 is closed, and the first valve 60 is opened, so that the qualified plastic chips are discharged through the discharge pipe 6.
And the second method comprises the following steps: referring to fig. 7, the discharge port 12 is connected to a discharge pipe 6 and a conveying pipe 7 for conveying plastic chips from the discharge port to the feed hopper 11, and one end of the discharge pipe 6 opposite to the discharge port 12 is connected to a screen for passing qualified plastic chips. Because the screen is arranged at the end of the discharge pipeline 6 opposite to the discharge port 12, as long as unqualified plastic fragments are deposited on the screen, the plastic fragments can easily enter the conveying pipeline 7 and return to the feed hopper 11 for re-shredding; and qualified plastic chips are discharged from the discharge pipeline 6.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
