Technical Field
The present invention relates to a material collection apparatus and, more particularly, to structural aspects of the material collection apparatus.
Background
Typically, a material collection device such as a walk behind leaf collector may comprise a rotating brush disposed within a housing. The rotating brush may rotate and contact the ground when the device may be moved over the ground. When the rotating brush contacts and moves over the fallen leaves present on the ground, the rotating brush may collect the fallen leaves and transfer the collected fallen leaves to an adjacent storage compartment.
However, in many cases, the rotating brush may include straight blades and/or bristles. Such straight blades and/or bristles create considerable resistance to movement over the ground, making the collection process labor and time consuming. Also, due to the straight blades and/or bristles, the total area present within the housing and/or around the rotating brush may be inefficiently utilized, reducing the productivity and material collectability of the apparatus. There is therefore a need for an improved construction of such a rotary brush for use in the apparatus.
Disclosure of Invention
In view of the above, it is an object of the present invention to solve or at least reduce the above disadvantages. According to an embodiment of the invention, the object is at least partly achieved by a material collection apparatus. The material collection apparatus includes an implement compartment and employs an operative implement according to an embodiment of the present invention. The operating means comprises a pair of rollers adapted to propel the operating means about an axis. The operating implement also includes an axle located within the implement compartment and having a pair of ends coupled to the pair of rollers. The operating implement further comprises at least one pair of blades coupled to the axle. Each vane of the at least one pair of vanes is angularly offset from each other and includes a first vane and a second vane. The first blade extends in a direction away from the hub. The second blade also extends in a direction away from the hub and is disposed in a side-by-side relationship with respect to the first blade. The second blade is disposed adjacent to the first blade and offset at an angle relative to the first blade. Each of at least one of the first and second blades of the at least one pair of blades includes a leading edge and a trailing edge. Whereby one of the leading edge and the trailing edge of each of the blades is disposed proximate a respective end of the hub. In the context of the present application, the leading edge of a blade is defined by: when the material collection apparatus is moved over the ground to collect an object on the ground, the leading edge of a blade contacts the ground (or an object on the ground) earlier than the trailing edge of that blade.
Assuming that the leading edge of each of the blades is disposed near the respective end of the hub, any movable objects will first be contacted by the leading edge of the blade located near the respective end of the hub, and thereby be pushed inwardly into the appliance compartment. This will further improve the collecting capacity of the device in order to avoid accidental ejection of objects and, after it has been pushed inwardly into the compartment of the appliance, it will be possible to correctly collect objects which were only partially pushed at the outset. Assuming the arrangement of the blades is reversed, that is, the trailing edge of each of the blades is disposed near the corresponding end of the hub, objects on the surface will be pushed outside the appliance compartment. In this case, a suitable structure or airflow design of the appliance compartment may help to collect the propelled object.
Furthermore, the particular arrangement of the blade with leading and trailing edges, which is carried out in an advantageous manner, has the effect that the entire edge of the blade does not touch the ground at the same time. Thus, this arrangement creates relatively low resistance while moving over the ground during collection of material from the ground, thereby providing improved efficiency.
According to an embodiment of the invention, the at least one pair of blades has a Y-shaped configuration. The Y-shaped configuration provides a relatively stronger sweeping force.
According to an embodiment of the invention, each of the first and second blades of the at least one pair of blades defines a substantially double-helix configuration. Thus, the double helix configuration provides a relatively large surface area to collect material from the ground, thereby providing improved productivity. Moreover, the double helix configuration provides relatively low resistance when moving over the ground during collection of material from the ground, thereby providing improved efficiency.
According to an embodiment of the invention, each of the first and second blades of the at least one pair of blades defines a substantially flat and planar configuration. Thus, the flat and planar configuration provides a relatively large surface area to collect material from the ground, thereby providing improved productivity. Also, the flat and planar configuration provides relatively low resistance when moving over the ground during collection of material from the ground, thereby providing improved efficiency.
According to an embodiment of the invention, each of the first and second blades of the at least one pair of blades defines a substantially curved configuration. Thus, the curved configuration provides a relatively large surface area to collect material from the ground, thereby providing improved productivity. Moreover, the curved configuration provides relatively low resistance when moving over the ground during collection of material from the ground, thereby providing improved efficiency.
According to an embodiment of the invention, each of the first and second blades of the at least one pair of blades defines a substantially angular configuration. Thus, the angled configuration provides a relatively large surface area to collect material from the ground, thereby providing improved productivity. Moreover, the angled configuration provides relatively low resistance when moving over the ground during collection of material from the ground, thereby providing improved efficiency.
According to an embodiment of the invention, the appliance further comprises a coupling member coupled to the axle and extending radially away from the axle. As such, the coupling member is adapted to couple to the at least one pair of blades. The coupling member provides a simple and effective way to couple the at least one pair of blades with the hub, thereby providing improved usability, simplified installation, reduced labour, etc.
According to an embodiment of the invention, said coupling means associated with said at least one pair of blades form a substantially Y-shaped configuration. Thus, the Y-shaped configuration provides a relatively stronger sweeping force through the leading blade in one of the first and second blades of the at least one pair of blades to lift material from the ground. In addition, the Y-shaped configuration provides a drift or thrust force to the material being lifted through the rear blade of the at least one pair of blades to transfer the material into the storage compartment.
According to an embodiment of the invention, each of the first and second blades comprises a first portion and a second portion coupled to the first portion. As such, each of the first and second portions provides a variable structural, structural and/or operational configuration for each of the first and second vanes.
According to an embodiment of the invention, the second part comprises an arrangement of bristles. As such, the bristle configuration provides a flexible end surface for each of the first and second blades to provide improved sweeping action, improved material collection, improved productivity, reduced damage to the floor, and the like.
