Description

Wide-width rotary cleaning machine for mulching film

Technical Field

The invention belongs to the technical field of mulching film recovery equipment of agricultural machinery, and particularly relates to a mulching film wide-width rotary cleaning machine.

Background

As is known, after the mulching film is adopted for cultivation, the temperature and the moisture condition of soil and the near ground can be improved, and the effects of improving the soil temperature, keeping the soil moisture, improving the soil property, improving the soil nutrient supply condition and the fertilizer utilization rate, improving the illumination condition, reducing the harm of weeds and pests and the like are achieved; because of the higher cost of the degradable film, farmers are reluctant to accept the degradable film, the agricultural film used by the degradable film is mainly made of common PVC plastic film, and because the degradable film can not be degraded, the degradable film can cause serious pollution to soil when being left in a field, sometimes the growth of seedling roots is hindered, moisture is isolated, seedling withering and death are caused when the degradable film is serious, the plastic film residue can cause resource waste when being thrown into the field, the recovery of the residue film is time-consuming and labor-consuming, and especially, the residue film recovery effect of the mulching film recovery machine in the prior art is poor, so that the residue film recovery is not clean.

Most existing mulching film recycling machines can only recycle residual mulching films paved on the ground surface, mulching films collected in the mode are scattered, the picking rate is not high, and the problems of film clamping, difficult demolding and the like easily occur. The existing residual film recycling machine is large in size, complex in structure and high in cost, and is particularly not suitable for recycling plant mulching films. In the film paving of the plants, ridge and furrow conditions exist, and after the film is paved on the ridge, the two sides of the film need to be covered with soil and pressed. In addition, the agricultural film buried in the soil on both sides of the ridge cannot be recovered by the existing residual film recovering machine. The cleaning work after ridge type film paving can only be carried out manually, and the labor intensity is high.

Disclosure of Invention

The invention provides a mulching film wide-width rotary cleaning machine which has a function of fully recovering rotten films and residual films, and aims to solve the problems that an existing mulching film recovery mechanical structure is complex and cannot be suitable for a residual film recovery function.

The following technical scheme is adopted for achieving the purpose: a mulching film wide-width rotary cleaning machine comprises a fixed frame and a turnover frame, wherein the fixed frame and the turnover frame are hinged together through hinges and fixed through lock catches, and the turnover frame can be turned upwards from one side of the fixed frame; a fixed vertical pipe shaft is arranged at the rear end of the turnover frame, a shaft sleeve is sleeved outside the fixed vertical pipe shaft through a bearing, and a belt pulley is mounted on the shaft sleeve and is in transmission connection with a rotary driving motor through a belt; the lower end of the fixed vertical pipe shaft is provided with a universal inner wheel, and the side wall of the fixed vertical pipe shaft is provided with an air inlet hole; the lower end of the shaft sleeve is connected with a conical cover with a narrow upper part and a wide lower part, and the peripheral edge of the bottom of the conical cover is provided with an annular flexible sticking disc; and meanwhile, a negative pressure chamber is arranged in the fixed frame or the turnover frame, an exhaust fan is arranged in the negative pressure chamber, and an air inlet of the negative pressure chamber is communicated with the inner cavity of the conical cover through an exhaust pipe and a fixed vertical pipe shaft.

And a filter screen is sleeved outside the air inlet of the fixed vertical pipe shaft.

The inner side of the flexible sticking disc is provided with a support ring, and air inlet channels are distributed on the support ring along the radial direction. And the lower surface of the flexible sticking disc is uniformly provided with convex film grabbing teeth.

The invention has the beneficial effects that: according to the invention, the driving conical cover and the flexible sticking disc are arranged on the turnover frame, so that the ground can be thoroughly cleaned under the condition of being fully stuck to the ground. And residual mulching films scattered on the ground can be sucked into the conical cover for temporary storage by virtue of the negative pressure air draft mechanism. The adopted overturning frame structure can clean the conical cover regularly, and is simple and convenient to operate.

The adopted flexible pasting disc can be always kept to be pasted with the ground according to the terrain condition, so that the air inlet can be reduced, and the suction function is increased. The convex membrane tooth of grabbing that distributes in flexible pad pasting lower surface can also keep the peripheral even intake of flexible pad pasting when grabbing the membrane effect, reaches comprehensive convulsions effect.

In the invention, the adopted conical cover also has the function of separating soil and residual mulching films, and the mulching films are easy to move upwards due to the adoption of a negative pressure mode, but soil particles can fall off greatly in the rising process of the mulching films.

Detailed Description

Example 1: referring to fig. 1, the mulching film wide-width rotary cleaning machine comprises a fixed frame 1, a turnover frame 3 and a rotary motor. The fixed frame 1 and the turnover frame 3 are hinged together through a hinge 4 and fixed through a lock catch 16. The turnover frame 3 can be manually driven or is provided with a driving arm which turns upwards along one side of the fixed frame 1.

As can be seen from fig. 1, a fixed riser shaft 8 is provided at the rear end of the roll-over carriage 3, and a bushing 9 is fitted through a bearing to the outside of the fixed riser shaft 8. The shaft sleeve 9 is provided with a belt pulley 10 and is in transmission connection with the rotary driving motor 5 through a belt 10. The lower end of the shaft sleeve 9 is connected with a conical cover 12 with a narrow upper part and a wide lower part, and the bottom peripheral edge of the conical cover 12 is provided with an annular flexible sticking disc 13. The conical cover 12 also has the effect of separating soil from residual mulching films, and the mulching films are easy to move upwards due to the negative pressure mode, but soil particles fall off in a large amount in the rising process of the mulching films.

The lower end of the fixed riser shaft 8 is located within the conical housing 12 and the end thereof is fitted with an internal universal wheel 14. The fixed frame 1 is provided with an outer wheel 15. The universal inner wheel 14 and the outer wheel 15 are matched to move the whole vehicle frame.
