Abstract
A means of accurately measuring farm chemical during its application, through the use of load cell and a means of mounting this load cell to a sprayer apparatus is disclosed. The measurement of the chemical is accomplished by the use of a load cell which is mounted in a position below a keg of liquid farm chemical. The load cell measures the weight of the chemical keg and the liquid chemical contained therein. By knowing the specific gravity of the chemical being used and the weight of the keg itself, the operator can accurately compute the volume of chemical which has passed through the sprayer system and the rate of that passage. This gives the operator an accurate measure of the amount of the liquid chemical applied to each acre of crop land.
Claims11
An agriculture chemical application unit with chemical measuring device comprising:
- A direct injection sprayer unit having a separate water holding tank and chemical holding tank said sprayer unit being powered by an attached tractor;
- An accessory bay mount;
- A load cell fixably mounted inside said accessory bay mount;
- A means of attaching said accessory bay mount to said sprayer unit;
- A strain gauge display mounted in said tractor;
- A connection means between said strain gauge display and said load cell with a second connection to a electrical power supply;
- and
- A means for removably mounting said chemical tank on said load cell above said accessory bay mount.
An agriculture chemical application unit with chemical measuring device comprising:
- A direct injection sprayer unit having a separate water holding tank and chemical holding tank said sprayer unit having a built in drive means and cab;
- An accessory bay mount;
- A load cell fixably mounted inside said accessory bay mount;
- A means of attaching said accessory bay mount to said sprayer unit;
- A strain gauge display mounted in said sprayer cab;
- A connection means between said strain gauge display and said load cell with a second connection to a electrical power supply;
- and
- A means for removably mounting said chemical tank on said load cell above said accessory bay mount.
A method of determining and monitoring the amount of chemical being applied to a crop by a direct injection type sprayer having separate chemical and water tanks comprising the steps of:
- (a) mounting a load cell to the sprayer;
- (b) mounting the chemical tank to said load cell;
- (c) powering the sprayer by an attached tractor, or by providing the sprayer with a built in drive unit and cab;
- (d) taking a first reading from said load cell;
- (e) directly injecting chemical from said chemical tank into a stream of water from said water tank;
- (f) applying said chemical in said stream of water to a crop over an area Y;
- (g) taking a second reading from said load cell;
- and
- (h) calculating the amount of chemical used from the first and second readings from said load cell.
