Abstract
The present invention relates to a sugar cane harvester and more particularly to a sugar cane harvester having an improved impurity removal fan assembly. The improved impurity removal fan assembly includes a central metal hub (25), a top hub (27), a hemispherical bottom hub (23), a hub adapter (29) and fan blades (31) of airfoil design. To revive the dead zone, a hemispherical bottom hub (23) is added to the hub assembly. Increasing fan efficiency by adding a hemispherical bottom hub (23) allows the same amount of air to move at a slower fan RPM, which in turn eliminates dead zone effects by reducing the dead zone to one point; however, the largest proportion of leaves and extraneous waste is removed when passing through the outermost annular ring of high velocity air.
Description
Technical Field
The present invention relates to a sugar cane harvester, and more particularly to a sugar cane harvester having an improved impurity removal fan assembly.
Background
There are various types of sugar cane harvesters in the art that harvest growing sugar cane stalks by cutting the cane at the root of the cane and then transfer the cut cane to a collection vehicle such as a cane carriage or a cane cart. The sugar cane harvester can include different types of harvesting devices. Harvesting devices for sugar cane harvesters may include assemblies for cutting, sectioning, sorting, transporting, and collecting and processing sugar cane plants. Typically, harvesting devices include crop separator assemblies, squeeze roller assemblies, root cutter assemblies, feed rollers, cutting drums, trash removal fan assemblies, and the like.
For dynamic crop harvesting, a harvester having a harvesting device as described above can be moved along a field, wherein the harvesting device performs collection and treatment of material from a row of crop plants. The trash fan assembly operates as an air flow device to create an air flow to separate and expel foreign matter such as leaves and dirt from the sugar cane cut stream.
In addition, conventional impurity removal fan assemblies have achieved a variety of fan designs. Some have small hubs with long blades and others have large hubs with short blades. In either case, there is a dead zone region directly beneath the hub, such that there is little air flow from the clean room region directly beneath the hub. Due to the limited movement of air under the hub, waste material may accumulate in this particular area and may cause parts of this area to become stuck, thereby affecting the function of the impurity removal fan and requiring frequent maintenance. In some cases, the dead zone region may be much larger than the actual hub diameter. When numerous fans are attached to a small hub, blade overlap or near overlap occurs. Very little, if any, air movement occurs in this overlap region and very little, if any, foreign material is expelled through this region.
Various prior art techniques have been disclosed for describing the trash removal fan assembly of a sugar cane harvester. The prior art document US9119346B2 describes a fan driven impurity removal system for a sugar cane harvester which utilises a rotating impurity removal screen which moves through the airflow path so that air flows through the screen to collect leaves and other crop residues in the air and carry them away from the airflow and deposit them on the ground beside or behind the harvester or deposit them on another receiver without passing through the fan.
Another prior art document US4677813a describes a sugar cane harvester in which crop cuts are transported from a cutting mechanism to a cleaning mechanism. The cleaning mechanism includes a debris removal fan positioned in an upper portion of the cleaning cartridge and a substantially unobstructed air intake around a periphery of the cleaning cartridge. The air inlet draws air through the air inlet in a generally downward direction and into the cleaning cartridge and passes the air upwardly through a majority of the crop after exiting the sectioning mechanism.
Furthermore, a further prior art document WO2018/064723A1 describes a cleaning system for a sugar cane harvester having a blower system, a impurity removal system, a separation system and a transport system. The blower system preferably directs the air stream to a separation system, and the separation system is preferably configured to receive harvesting material in the air stream and separate an extraneous portion of the material to the impurity removal system, while separating a desired portion of the material to the transport system.
However, the aforementioned conventional trash removal fan assemblies of sugar cane harvesters are complex in nature and have not been explicitly described with respect to eliminating dead zone areas that create a build-up of trash around the fan hub structure. In addition, the blade design of the conventional trash removal fan is not promising in terms of efficient discharge of the trash. Furthermore, there are structural drawbacks in retaining lighter sugar cane that may be easily thrown out of the clean room.
The conventional trash fan assembly described above suffers from various problems that result in affecting the performance of the trash fan and, in turn, the overall efficiency and output of the sugar cane harvester. Accordingly, there is a clear need to invent a sugar cane harvester having an improved trash fan assembly with a unique design to eliminate dead zone effects, achieve efficient waste discharge, retain lighter sugar cane, save fuel and operate at lower revolutions per minute and have a higher cubic foot rating per minute.
Object of the Invention
The primary object of the present invention is to overcome the problems associated with conventional trash removal fan assemblies for sugar cane harvesters by providing an improved trash removal fan assembly for properly removing waste material at a terminal point.
It is a further object of the present invention to provide an improved impurity removal fan assembly for eliminating dead zone effects by reducing the dead zone to a point.
It is a further object of the present invention to provide an improved trash removal fan assembly for removing a maximum percentage of leaves and extraneous waste.
It is also an object of the present invention to provide an improved trash removal fan assembly for retaining lighter sugarcane sections.
It is a further object of the present invention to provide an improved trash removal fan assembly for saving fuel and operating at lower revolutions per minute having a higher rated value of cubic feet per minute.
Disclosure of Invention
The present invention relates to a sugar cane harvester, and more particularly, to a sugar cane harvester having an improved impurity removal fan assembly. The improved impurity removal fan assembly comprises: a central metal hub; a dome-shaped top hub secured to the top of the central metal hub by a hub adapter and fastening means; a hemispherical bottom hub secured to the bottom of the central metal hub by a hub adapter and fastening means; and a plurality of airfoil-designed fan blades secured to and extending radially relative to the central metal hub by a plurality of fastening means. To restore the dead space, a hemispherical bottom hub is added to the fan hub. Increasing fan efficiency by adding a hemispherical bottom hub allows the same amount of air to move at a slower fan RPM, which in turn eliminates dead zone effects by reducing the dead zone to one point; however, the largest proportion of leaves and extraneous waste is removed when passing through the outermost annular ring of high velocity air.
The impurity removal fan assembly of the present invention provides multiple benefits to the end user, which are described in the pages of the following specification.

Detailed Description
Before explaining the present invention in detail, it should be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways from those described in the figures. It is to be understood that the phraseology and terminology used herein is for the purpose of description and not of limitation.
It will be further understood that the terms "comprises" and their grammatical equivalents are used herein to denote the optional presence of other components, ingredients, steps, etc. For example, an article "comprising" components A, B and C may consist of (i.e., contain only) components A, B and C, or may contain not only components A, B and C but also one or more other components.
The invention discloses a sugarcane harvester with an improved impurity removal fan assembly. Now, in accordance with the present invention, a sugar cane harvester is particularly directed to improving the functional overview of the trash removal fan assembly as shown in the drawings. In fig. 1, a sugar cane harvester is shown, comprising: a tip remover assembly (10) for cutting foliated material of sugarcane stalks; an aggregation zone (11); a crop separator assembly (12) for lifting and riding over a row of sugarcane stalks; modular knock-down rollers (not shown) and fin rollers (not shown) for helping align plants for feeding into the throat of the harvester; a pair of root cutters (13) for cutting sugar cane stalks from a field; a frame portion (14 a, 14 b); a feeding zone (15) comprising a feeding roller system for further moving the cut cane stalks in a rear-up direction without damaging or crushing the cane; a cutter system or cutter drum (19) for cutting the sugar cane stalks into small pieces in the form of short sections; an improved clean room (16) having a trash removal fan assembly (39) (i.e., a primary trash removal fan) for separating dirt and foreign materials from a short section by blowing air onto the short section; a lifting system (17) comprising a secondary impurity removal fan for removing the remaining loose material when the sugar cane falls from the transport extremity; an operating room (18) for operating and controlling the harvester; a pair of hydraulic cylinders (21); and a discharge zone (22) for discharging the harvested sugarcane stalk short sections.
The sugar cane harvester of the present invention utilizes an air flow device within the clean room (16) to create an air flow to separate foreign matter such as leaves and dirt from the sugar cane slices and to expel it from the sugar cane slice flow. This separation occurs in the clean room (16).
Referring to fig. 2, according to an exemplary embodiment of the present invention, the cleaning chamber (16) includes: a trash-removal fan assembly (39) having an axial flow fan (referred to as a trash remover or air generating device) for removing dirt and foreign matter; a cylindrical barrel (32) mounted on the impurity removal fan assembly (39); and an axial piston motor (33) partially or fully received within the cylindrical barrel (32) and drivingly connected to the impurity removal fan assembly (39).
The invention also discloses an arrangement of a plurality of deflector blades or gratings (36) extending partially inwardly from the inner wall of the clean room (16), as shown in fig. 2. The deflector blades (36) are used to separate cut leaves and debris from the short length of sugar cane and to flow them to the clean room (16) through a deflector surface facing the feed stream. The guide surfaces of the deflector blades (36) deflect a portion of the feed stream away from the outlet as it is carried by the air stream into the cleaning chamber (16). Furthermore, the deflector blades (36) have support fins (37) which retain lighter sugar cane in the clean room (16) and do not allow for outflow with the waste material, thereby minimizing the loss of sugar cane through the trash separator annular discharge zone (22).
Detailed views of the impurity removal fan assembly (39) are shown in fig. 3 and 4. As shown in fig. 3 and 4, the impurity removing fan assembly (39) includes: a central metal hub (25); a dome-shaped top hub (27) secured to the central metal hub (25) by a hub adapter (29) and fastening means (i.e., bolts (28) and nuts (24)); a hemispherical bottom hub (23) secured below the central metal hub (25) by a hub adapter (29) and fastening means (i.e., bolts (28) and nuts (24)); and a plurality of fan blades (31) secured to the central metallic hub (25) by fastening means (i.e., a plurality of capped screws (26, 30)) and extending radially relative to the central metallic hub (25). A central metal hub (25) is associated with the motor cone shaft (not shown) and a hub adapter (29). The central metal hub (25) is coupled with a top hub (27) made of polyethylene material and a bottom hub (23) made of the same polyethylene material.
To revive the dead zone, a hemispherical bottom hub (23) is added to the fan hub as shown. Due to the hemispherical shape of the bottom hub (23), fan efficiency is improved, so that the same amount of air can be moved at a slower fan RPM, which in turn eliminates dead zone effects by reducing the dead zone to one point; however, the largest proportion of leaves and extraneous waste is removed when passing through the outermost annular ring of high velocity air.
Furthermore, the fan blades (31) are blades of airfoil design. Blades (31) of airfoil design have been developed and the key points of effort are: i) A leading edge curve; ii) a waste discharge profile; iii) A depletion expansion curve (exhausting flare curve). These three points form a unique design that has proven to save fuel and operate at lower revolutions per minute and higher cubic feet per minute ratings.
In accordance with another embodiment of the present invention, the structural features of the top and bottom hubs of the impurity removal fan assembly (39) are shown in fig. 4. The top plastic hub (27) is bolted to the upper flange portion (34) of the central metal hub (25). An inner PCD (38) at the central metal hub (25) is bolted to the hub adapter (29) and motor shaft (not shown). An inwardly extending plate (35) has a bottom plastic cover (23) for assembly to the central metal hub (25).
A top view and a front view of the impurity removal fan assembly (39) are shown in fig. 5a and 5b, respectively. An impurity removal fan assembly (39) is mounted above the flow of the cut material, with unwanted material passing through the fan itself. The cleaning chamber (16) is circular in shape to match the shape of the impurity removal fan assembly (39). The material to be separated is introduced into the clean room (16) from one side and typically within two feet of the trash removal fan assembly (39). At this distance from the impurity removal fan, the air velocity at the tip of the blade is highest, with the velocity decreasing continuously toward the center of the fan. However, by arranging the hemispherical bottom hub (23), the air flow is evenly distributed within the clean room (16), eliminating dead space, so that foreign matter is effectively removed from the clean room (16). Most of the foreign matter is removed as it passes through the highest velocity region. This occurs as the material enters the cleaning chamber (16) and reaches the distal side of the cleaning chamber (16) again.
The invention has been described with respect to specific embodiments. It is to be understood that the foregoing description is illustrative of the present invention and is not intended to be limiting or limiting. Many other specific embodiments of the invention will be apparent to those skilled in the art in light of the foregoing disclosure. All substitutions, modifications and alterations of the invention within the scope of the appended claims are readily accepted by the present invention without departing from the spirit of the invention. The scope of the invention should, therefore, be determined not with reference to the above description, but instead should be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
