Spreader with adjustable directional outlet

Abstract

A spreader for spreading materials comprising a case for holding a product to be spread. The case comprising an aperture for ejecting the product to be spread from the case. The spreader further comprising a conveying device for displacing a portion of the product to be spread in a direction towards the aperture. The spreader equally comprising aperture adjustment device for controlling the displacement of an aperture obstruction device relative to an aperture surface of said aperture. The spreader further comprises a speed controller for setting the speed of the conveying device. The spreader comprises as well a blower for projecting the product to be spread, the blower having an inlet and an outlet. The direction of the outlet is adjustable along different angles. The spreader also comprises a angle adjustment system for the outlet of the blower. The inlet of the blower is placed at an angle relative to the aperture of the case.

Description

FIELD OF THE INVENTION[0001]The present invention relates to spreaders. More particularly, the present invention relates to a spreader with a blower having a directionally adjustable outlet.BACKGROUND OF THE INVENTION[0002]The spreading of materials such as lime or ash, for foresting or agricultural applications is usually made through the use of spreaders.[0003]In order to facilitate their tuning and to allow a more precise control of the quantity of products to be spread, certain spreaders have been equipped with electronic control means like what has been described in European patent application 1797751. These types of control means can control a hydraulic moving carpet device placed at the end of the spreader, in a manner to control the volume and the force of the products to be spread onto a terrain. However, the scattering mechanisms of such spreaders project the products in a manner that is often random and over short distances.[0004]As such, the spreaders of the prior art ca...

AI Technical Summary

Benefits of technology

[0005]The present invention proposes a spreader that addresses at least one of the fore-mentioned needs and allows an efficient control of the distance and the direction of the spreading of the material.

[0015]The invention concerns a spreader which functions similarly to a snow blower allowing, for example, lime to be sent from one side to the other of the spreader in an adjustable fashion. The spreader can be towed by a all-terrain vehicle or by any small four-wheel vehicle. The invention can be used on maple tree farms to spread on material on the maples in order to protect their development. The device also allows for the spreading of manure, granular lime, as well as lime in the form of powder.

[0016]The invention is useful for the protection of different types of trees. For example, maple is a tree which can grow in different types of soils, including acidic soil. However, its growth is optimized when the soil is just slightly acidic. The spreading of lime reduces the acidity around maple trees, thus increasing the yield from 15 to 20% of the maple farm. The spreader can also be used for blueberry farms, strawberry farms, as well as orchards and vineyards. The invention is particularly useful in vineyards where there is typically not a lot of space to circulate machinery between the vines. The compact design of the apparatus allows circulation with ease between rows of vines having small space between them.

Problems solved by technology

However, the scattering mechanisms of such spreaders project the products in a manner that is often random and over short distances.

As such, the spreaders of the prior art cannot spread product over long distances in precise directions nor can they equally be adjusted and controlled with ease.
