SILAGE DENSITY PROBE

Abstract

A silage density measuring device that is insertable into a mass of silage. The device comprises a probe that penetrates the mass of silage a certain distance. A load cell is connected to the probe and measures an amount of force needed to insert the probe the distance into the mass of silage. The amount of force is utilized to give a density of the silage and the amount is shown on a display monitor. The device is mountable on a load bucket which assists in avoiding accidents involving silage avalanches.

DETAILED DESCRIPTION OF THE INVENTION

[0013] FIGS. 1 through 4 show a silage density measuring device 20 used for measuring the density of a pile of silage. The device 20 comprises a probe 22 and a frame 21. A loading bucket of a typical farm tractor as shown in FIG. 6 can be attached to the frame 21 via fastening mechanisms such as brackets 24. The device further comprises a mechanism for measuring a particular force, the preferred embodiment utilizes load cell 25. Additionally, the load cell 25 is connected to a display monitor 26 via a cable 28 so the amount of force can be viewed by a user of the device 20. A gauge 30 can be attached to the device 20 or in particular to the probe 22 to check for levelness of the probe 22.

[0014] As shown in FIGS. 1-3, the frame 21 comprises a first side plate 32 and a second side plate 34. The frame 21 further comprises a first support member 36 and a second support member 38. The first support member 36 and second support member 38 are attached to the first side plate 32 and second side plate 34 such that they form perpendicular angles to one another. Preferably, the second support member 38 fits within a cavity 40 of the first side plate 32 and a cavity 40 of the second side plate 34. The cavities 40 are preferably square and the second support member 38 has a complimentary shape to fit within the cavities 40. The parts of the frame 21 are attached to one another with fastening mechanisms such as screws, bolts and washers.

[0015] The first side plate 32 and second side plate 34 each have a first end 62 and second end 64. Toward or at the second end 64, the brackets 24 which can be clamps are threaded through openings 60 in the first side plate 32 and second side plate 34. The plurality of brackets 24 are tightened such that they can be clamped onto a secondary piece of equipment such as a bucket of a typical farm tractor as shown in FIG. 5. The first support member 36 has an opening 50 through which a probe shaft 46 can be fitted. The probe shaft 46 is connected to the probe 22 and the load cell 25. Preferably the load cell 25 is a compression load cell that can bend or a pancake load cell. The probe 22 has a tip 68. The load cell 25 is attached to the frame 21, preferably to the second support member 38, via a fastener 70 such as a bolt and a washer 72.

[0016] In practice, the device 20 is selectively attached to a bucket of a farm tractor utilizing the brackets 24. Once attached, the tip 68 of probe 22 is pointing outward from the bucket. The cable 28 can be of a sufficient length for the display monitor 26 to be in the cab of the farm tractor. While FIG. 5 shows the display monitor 26 near the bucket, the preferred embodiment has the display monitor in the cab such that a user of the farm tractor can read the display while seated in the cab. The use of the device 20 can then drive the farm tractor to make contact with a particular pile of silage with the probe 22. The probe 22 and probe shaft 46 can be entered a desired distance into the silage. A depth marker 80 is on the probe shaft 46 and assists in determining the depth of the probe shaft 46 in the silage. The contact of the probe 22 with the silage causes a force to be exerted against the load cell 25 which is then shown on the display monitor 26. The density of the silage can be calculated by plugging the force value into a linear regression equation. Certain values of the silage, including density, can be determined and shown on the display monitor 26.
