GRAIN CART WITH AIR NOZZLE
This invention relates to an agricultural cart for transporting particulate material such as grain, seed and fertilizer.
BACKGROUND OF THE INVENTION
Grain carts are farm implements that are typically towed behind a tractor and are used to transport harvested grain from other implements, such as combines, and deliver the grain to trucks or other hauling devices away from the harvest field. The use of grain carts allows the harvester to unload in the field to increase efficiency and so trucks can remain off the field.
Grain carts typically include a storage carrier that further includes at a with a total capacity ranging from several hundred to over one thousand bushels of grain. To unload the grain from the cart, grain carts employ a conveying device such as an auger to draw grain from the bottom of the hopper and convey it to a discharge end. At the discharge end the material is carried through a feed tube by a further auger that deposits the grain to a discharge location. The conveyor transports grain from the base of the hopper upward so that it may be deposited into another container which can be a transport truck when transporting grain or can be a seeder when the cart is used to fill the seed tank of a seeder.
At the bottom of the hopper, where the conveyor meets the hopper, is typically a door that must be opened in order for grain to flow onto the conveyor. The door serves the purpose of keeping the grain or other material in the hopper until the operator desires to remove the material, and also of allowing the conveyor to come

8 as to impinge on the auger flight and swirls around the flight to clean out the tube.
However this arrangement herein can also be used with other types of conveyor.
In addition or as an alternative to the clean out described above, the nozzle can also be arranged to direct the stream of air toward the discharge end to accelerate flow of the particulate material along the tube.

The arrangement herein therefore provides the advantage that the cart is arranged for transporting different materials and the nozzle is arranged to clean out the conveyor after discharge of one material before discharging another material.
The unit thus is able to act as a grain cart as well as a seed tender vehicle. In the spring it will be used to fill air tanks behind air drills very quickly and in the fall be used as a grain cart alongside combines.
In order to be used as a seed tender cart the augers are cleaned completely out when changing from product to product. To accomplish this, forced air is blown into the end of both the horizontal auger along the bottom of the cart as well as the vertical auger going up to air tank or truck. This air can go through one auger at a time or possibly both at the same time. In order to achieve a sealed chamber (auger) for air to successfully clean out product in the horizontal auger there are sliding doors at the bottom of the hoppers that close, thus stopping the flow of grain into the auger as well as sealing it off so it can be blown out.
The arrangement herein can also be used as an air assist for the auger where the air stream injected into the auger tube is used to increase flow capacity of the auger. This arrangement can be used for example in regular grain augers, combines, frac-sand applications, and augers that move shavings and all kinds of products.

10 The application of cleaning both in the horizontal and inclined augers tubes is typically used when this machine is used as a seed tender cart for filling air tanks behind seeding equipment. When changing from seed to fertilizer no excess material remains in the augers which will prevent contamination of seed and fertilizer. As well, the operator does not have to contend with the excess material that typically remains in fill augers of air tanks which typically requires reversing the auger then having to carry pails of it to the top of the tank and dumping them in. the arrangement herein is cleaner, faster, and more safe. When this machine is used as a grain cart the doors on the bottom of the hoppers all open in unison. The centre door opens from the opposite side to ensure material empties evenly from both sides of the tank so as to not overload one side. The blower system typically is not be used during this application for clean out, but it can be used to increase capacity of flow of the material in the augers.

They are controlled via a single orbital motor 21 for each door. Each motor turns gear 20 that in turn moves the rack 19 that is attached to the doors to control the flow of product and to seal the horizontal auger at the time of clean out.
As shown in Figure 4, the closure door 135 of the hopper 132 moves to a side of the tube opposite to the doors 134 and 136 of the hoppers 131 and 133.
This acts to balance the unloading.
The outlet 173 of the blower 17 is connected to an air supply system 22 including a splitter 221 feeding two separate hoses 223 and 224 and a diverter valve 222 operable by a slider 225 for selecting one or both of the hoses for the stream of air. The hose 224 extends from diverter valve 222 at the front end 14 of the cart to the rear end 15 for connection to the rear end of the tube 161.
The hose 223 extends from the diverter valve 222 to the bottom end of the tube 162. As best shown in Figure 7, the hose 224 connects to an end wall 23 of the tube 161 where there is provided a nozzle 24 which is arranged at the bottom of the tube 161 so that the air stream from the hose passes longitudinally along the tube and particularly along the bottom part of that wall.
The nozzle 24 is thus mounted on the cart and arranged to direct the stream of air toward a surface of the cart and in this case against the surface of the auger flight 167 within the tube 161. The injected air is forced by the flight outwardly against the inside surface of the tube and thus tends to swirl around the outside
As shown in Figure 4, the closure door 135 of the hopper 132 moves to a side of the tube opposite to the doors 134 and 136 of the hoppers 131 and 133.

The nozzle 24 is thus mounted on the cart and arranged to direct the stream of air toward a surface of the cart and in this case against the surface of the auger flight 167 within the tube 161. The injected air is forced by the flight outwardly against the inside surface of the tube and thus tends to swirl around the outside
15 edge of the flight at the tube acting to drive any collected material at this location along the tube to the discharge end thus cleaning out the whole tube effectively and completely. In one example the airflow can be of the order of 1400 cfm and is arranged to pass through a pipe of the order of 2-3 inch diameter to a smaller nozzle at a pressure of around 15 psi into a 17 inch diameter auger tube and this has been found to provide full cleaning of any remaining material after the auger flight has carried out as much as it is able to do.
The hose 223 is connected at its end 226 to a second nozzle 241 similar to the nozzle 24 but located at the bottom end of the tube 162. This acts to inject the air into the tube at the bottom in the same manner to clean out the tube 161.
A similar nozzle is mounted at the bottom of the incline auger and has the same construction and operation as described above.
A hydraulically actuated slide gate 26 is mounted across the tube 161 at the junction with the tube 162 so that when the gate is actuated the duct 161 is closed off from the duct 162 to prevent air injected into the tube 162 from going backwards into the tube 161.
The doors 134, 135 and 136 are controlled automatically according to how much weight of product has left the tank while unloading. When a required weight has been delivered or the hoppers are empty, the doors are closed and the horizontal auger is still running. This causes the majority of product remaining in the auger tube 161 to generally clean out. However there is always small amounts of

The doors 134, 135 and 136 are controlled automatically according to how much weight of product has left the tank while unloading. When a required weight has been delivered or the hoppers are empty, the doors are closed and the horizontal auger is still running. This causes the majority of product remaining in the auger tube 161 to generally clean out. However there is always small amounts of
16 seed or fertilizer remaining in the auger. To completely clean this horizontal auger the blower 17 is now activated. To turn the blower on the system uses a controlled idler (not shown) to tighten the belt 171 and start the blower turning. The air diverter valve 222 sends all of the air from the blower to the rear of the machine through hose 224 and forces it into the horizontal auger. While the auger is turning the forced air carries all remaining seeds and product to the inclined auger.
At this point the hydraulic activated sliding gate 26 mounted between the horizontal auger and the incline auger is closed sealing the inclined auger tube 162 so that it may be blown out while the auger flight in the tube 162 is running. In order to have the sliding gate 26 at the front beyond the shaft 187, the shaft is driven from the rear end by the gear box 185 previously describe. Thus the two gearboxes 183, 185 are mounted at the rear of the machine to turn the horizontal auger flight 187.
The air diverter valve 222 now sends the air through the hose 223 to the base of the inclined auger tube 162 forcing air through it while the auger flight is running carrying all 15 product out the top and completely cleaning it of all material. At this point the blower is deactivated and the auger flights stopped.
A shown in Figure 9, the spout 28 of the auger portion 163 includes an upper spout portion 281 which is fixed to the auger portion 163 and discharges downwardly at a horizontal ring 282 into a lower spout portion 284. The ring defines an upstanding swivel axis 286 The portion 284 is inclined downwardly and outwardly from the axis 286 so as to form a downwardly facing mouth 285 spaced by a distance of the order of 24 inches from the axis. The lower portion is rotatable

The lower portion is rotatable
17 around the axis 286 at the ring 282 so that the mouth follows an annular path around the axis 286. This allows the spout and particularly the mouth to discharge vertically downwardly at different locations and at different spacing from the side wall of the container.
There are two main functions of the doors 134, 135 and 136. One is to control the flow of product flowing into the horizontal auger. The other is to seal the horizontal auger 167 so that while the auger is running and the air is turned on no air escapes out of the horizontal tube other than out the one end. The doors are designed to leave the least amount of blank space between the flighting of the auger and the door when it is closed. This encourages the flow of air to be directed in the direction desired and not leave product suspended in the air between the flighting and the bottom side of a door (inside the auger). It also helps to maintain a better air pressure inside the horizontal tube.
Figure 5 shows a close up of one of the orbital motors which opens and closes the door. It turns two to three spur gears (two are shown) per door which are seated into a rack. Using this system allows the doors to be opened evenly and easily. They can be opened partially or completely depending on the amount of product flow the operator desires. Using this orbital motor/spur/rack system will allow the door to be closed quickly for an emergency stop or where the desired amount of product has been dropped out of the hopper.
As shown in Figure 8, each door such as door 136 has bevelled front edges 29 bevelled rearwardly and downwardly which cooperate with bevelled edges

As shown in Figure 8, each door such as door 136 has bevelled front edges 29 bevelled rearwardly and downwardly which cooperate with bevelled edges
18 30 at the side edge of the respective opening 139 to shed any resting material. The reason for those edges is so that material does not hang up along the edges of the door frames. If the edges were not bevelled, material would become lodged in the crevices of the door frame when the door is opened and material flows out.
Also upon the door closing, product that is passing by the door will not become pinched or squashed along the edge of the door and door frame.
Above the doors on the inside of the hoppers as shown in Figure 1 is provided a triangular or roof shaped cover 31 with an upstanding apex along the center of the cover. The cover is spaced from the bottom wall of the hopper so that the material slides under the cover to the underlying opening. It is commonly used to take the weight of material off the auger but will be used here to aid in taking some of the weight off of the doors so that they may be opened and closed easier.
The doors 134, 135 and 136 can be opened and closed manually with a hydraulic lever or they can be controlled via a remote which an operator can use while standing on the top of an air tank observing how full his seeding tank is.
Once the operator has closed the door 134, 135, 136 of the hopper that is presently being emptied, he can then remotely turn on the blower and allow the air to clean out the horizontal auger of remaining product. Then the gate between the augers is closed as to seal both augers from each other. This horizontal/vertical separator gate 26 s opened and closed with a hydraulic cylinder 261 and can also be controlled remotely. Once again as above with the doors this gate is designed to allow the least amount of empty air space between the flighting

This horizontal/vertical separator gate 26 s opened and closed with a hydraulic cylinder 261 and can also be controlled remotely. Once again as above with the doors this gate is designed to allow the least amount of empty air space between the flighting
19 of the vertical auger and the gate. The surfaces of the frame of the gate is also angled downwardly to shed the material and so as to not allow material to hang up or become lodged in any crevice or ledges.
The blower turns at approximately 3600 rpm and is driven off of the driveline that runs the main gearbox at the bottom of the incline auger. The driveline is driven by a tractor and PTO that turns at a rated speed of 1000 rpm. Belts and pulleys are used to achieve the proper speed of the blower. It puts out 1400 cfm at around 12-15 psi. A silencer 175 is mounted near the air intake of the blower for operator comfort.
The air diverter valve 222 is used to direct the air flow from the blower to either the horizontal auger or the vertical or incline auger. As the control system is activated and is closing, this valve will switch to direct air flow from the horizontal auger to the vertical auger. As the gate 26 is activated hydraulically then so is this diverter valve 222. They work in unison as when the gate is open air is always diverted to the horizontal tube. As the gate is closed air will always be diverted to the incline auger.
At the top of the incline auger is a unique spout. The spout is designed with a downward angle and can be turned to fill 2-3 hoppers of an air tank from one position. The turning of the spout is controlled electrically. An electric motor turns a worm gear which allows the spout to turn 360 degrees. So from one position of the incline auger the operator can turn the spout to fill one hole then spin it remotely to the next hole in the air tank. The spout is designed to direct product vertically

20 straight down as opposed to exiting the spout at an angle which competitors do.
This will allow a more accurate placement of exiting product and will allow proper filling procedures of air tanks. Product leaving an inclined spout at an angle to the vertical acts fill one side of the air tank more than the other leaving empty space and an inconsistent load.
