Agricultural chaff collector
A combine and combine conversion for collecting agricultural plants in a manner that separates various parts of the plants for collection or disposal. A combine is provided with an improved system for collecting and cleaning seed of an agricultural material such as cannabis while collecting lightweight chaff, such as trichomes, and returning stalks back to the agricultural field. The system provides for rapid conversion of a combine to seed and chaff collection and back again.
1. An agricultural material collection system comprising:
(a) an agricultural vehicle;
(b) an agricultural material collector;
(c) a seed sieve;
(d) a thresher positioned above the seed sieve;
(e) a seed receiving area positioned at least partially below, the seed sieve;
(f) a blower in fluid communication with the seed receiving area;
(g) a chaff collection area in fluid communication with the seed receiving area;
(h) a seed collection area in fluid communication with the seed receiving area;
(i) a duct defining an interior in fluid communication with the chaff collection area;
(j) an impeller provided in fluid communication with the duct;
(k) wherein the duct is positioned between the seed receiving tea and the chaff collection area; and
(l) a cleaning shoe coupled to the agricultural vehicle;
(m) a ceiling pan located to receive material exiting the thresher, wherein the ceiling pan is coupled to the cleaning shoe in a manner wherein movement of the cleaning shoe relative to the agricultural vehicle is transferred to the ceiling pan.
2. The agricultural material collection system of claim 1 , further comprising a supplemental blower in fluid communication with the duct.
3. The agricultural material collection system of claim 2 , wherein the impeller is positioned to contact agricultural material during operation of the agricultural material collection system and wherein the supplemental blower is positioned so as not to contact agricultural material contacting the impeller.
4. The agricultural material collection system of claim 2 , further comprising a mobile processing assembly releasably coupled to the agricultural vehicle to form the agricultural material collection system, wherein the processing assembly comprises ground-engaging wheels and the supplemental blower, and wherein the processing assembly does not comprise the blower.
5. The agricultural material collection system of claim 4 , wherein the mobile processing assembly further comprises the impeller and the duct.
6. The agricultural material collection system of claim 1 , wherein the impeller comprises:
(i) an axle;
(ii) a first paddle coupled to the axle and extending at least partially across a first axial point along the axle; and
(iii) a second paddle coupled to the axle and extending at least partially across the first axial point along the axle.
7. The agricultural material collection system of claim 1 , wherein the impeller is rotating at a speed of at least two hundred and fifty revolutions per minute.
8. The agricultural material collection system of claim 1 , father comprising:
(a) a chaff suspension area in fluid communication with the seed collection area and the chaff collection area; and
(b) a stover conveyor forming at least a portion of a wall of the chaff suspension area.
9. The agricultural material collection system of claim 1 , wherein the chaff collection area is a trichomes collection area.
10. The agricultural material collection system of claim 1 , wherein the ceiling pan is coupled to the cleaning shoe in a manner wherein reciprocal movement of the cleaning shoe relative to the agricultural vehicle is sufficiently transferred to the ceiling pan to motivate material on the ceiling pan rearward relative to the agricultural vehicle.
11. The agricultural material collection system of claim 1 , wherein the ceiling pan is coupled to the cleaning shoe in a manner wherein reciprocal movement of the cleaning shoe relative to the agricultural vehicle is sufficiently transferred to the ceiling pan to motivate material on the ceiling pan rearward relative to the agricultural vehicle.
12. The agricultural material collection system of claim 1 , wherein a forward portion of the ceiling pan is resilient and a rearward potion of the ceiling pan is rigid compared to the forward portion.
13. The agricultural material collection system of claim 1 , wherein the ceiling pan is located and configured to seal the chaff collection area to substantially prevent the passage of the chaff out of the chaff collection area past the ceiling pan.
