Abstract
A fan blast volume adjusting board at least comprises a harvester wall board and a harvester fan, wherein the harvester fan is fixed on the harvester wall board through an engine base. The fan blast volume adjusting board is characterized in that a blast volume adjusting board is additionally arranged at air inlets on two sides of the fan below a harvester vibrating screen, the blast volume adjusting board is in semi-arc ring shape matching with the shape of an inlet of the harvester fan, slot holes are arranged on the blast volume adjusting board, adjusting screws which are sleeved inside the slot holes are arranged on lateral surfaces at two ends of the inlet of the harvester fan, and the blast volume adjusting board slides along the slot holes according to needs to reduce or increases the size of the air inlets so as to fasten the screws in the slot holes.
Description
Technical field
The utility model relates to a kind of part device of agricultural harvesting machine, the fan delivery that refers in particular to a kind of full feeding harvester is regulated adjusting device, can regulate the air quantity size according to the cleannes of cereal, the fan delivery adjustable plate that the cereal cleannes of feasible results are artificially controlled.
Background technology
Blower fan is the device that separates and throw grain that is used for the grain that will be gathered in and weeds in the grain header, because the situation of grain header harvesting when work is different, needed air quantity is also just different.But the blower fan below the grain header vibratory sieve is owing to install adjusting air quantity size at present, make the throwing grain that causes because of the different factors in the external world or the cereal that enters tanker be mingled with straw and can not arrive desirable effect, the wind how the reasonable use blower fan blows out separates grain and weeds, and accurately grain is thrown into that problem such as tanker can not get effective solution.Therefore necessary this is solved.
Summary of the invention
The purpose of this utility model is to propose a kind of new grain header fan delivery adjusting device at having the deficiency that the agricultural cutter fan delivery can't be regulated now, and this device can effectively in time be adjusted the air quantity of blower fan according to the different extraneous factor of grain header.
The purpose of this utility model is achieved through the following technical solutions, a kind of grain header fan delivery adjusting device, at least comprise a grain header wallboard, a grain header blower fan, the grain header blower fan is fixed on the grain header wallboard by support, it is characterized in that: the air inlet place, blower fan both sides below the grain header vibratory sieve has increased by an air-flow plate, air-flow plate is the half arc ring shape that matches with grain header fans entrance shape, on air-flow plate, have slotted hole, be with adjustment screw in the slotted hole, adjustment screw is installed in grain header fans entrance side faces at both ends, can be as required along slotted hole slip air-flow plate, reduce or increase the size of air inlet, the screw in the in position fastening slotted hole.
The utility model provides a kind of grain header fan delivery adjusting device, can be according to the bore of the working condition manual adjustment grain header fans entrance of grain header, thus adjust the intake of grain header blower fan, effectively realized the adjusting of grain header fan delivery.
Description of drawings
Fig. 1 is that air-flow plate installation rear fan master looks schematic diagram.
Fig. 2 is that air-flow plate is installed the rear fan schematic side view.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1, Fig. 2 discloses a kind of grain header fan delivery adjusting device, by accompanying drawing as can be seen, described grain header fan delivery adjusting device comprises a grain header wallboard 1 at least, a grain header blower fan 2, grain header blower fan 2 is fixed on the grain header wallboard 1 by support 3, it is characterized in that: grain header blower fan 2 both sides air inlets 4 places below the grain header vibratory sieve have increased by an air-flow plate 5, air-flow plate 5 is the half arc ring shape that matches with grain header fans entrance 8 shapes, on air-flow plate 5, have slotted hole 6, be with adjustment screw 7 in the slotted hole 6, adjustment screw 7 is installed in grain header fans entrance 8 side faces at both ends, can be as required along slotted hole 6 slip air-flow plates 5, reduce or increase the size of air inlet, the screw 7. in the in position fastening slotted hole
With reference to Fig. 1, Fig. 2: whole air inlet is on both sides, i.e. air inlet among Fig. 2.On the Blower Housing of blower fan two ends air inlet, increase by two bolts, be used to install the air-flow plate that has two slotted holes.Air-flow plate can laterally move the size that reduces or increase air inlet by slotted hole, levels up fastening air-flow plate in the suitable position of air quantity size with the nut bullet, makes that the air quantity size is artificially controlled.
Claims (2)
1. the fan delivery adjustable plate comprises a grain header wallboard, a grain header blower fan, and the grain header blower fan is fixed on the grain header wallboard by support, it is characterized in that: the air inlet place, blower fan both sides below the grain header vibratory sieve has increased by an air-flow plate.
2. fan delivery adjustable plate as claimed in claim 1, it is characterized in that: described air-flow plate is the half arc ring shape that matches with grain header fans entrance shape, on air-flow plate, have slotted hole, be with adjustment screw in the slotted hole, adjustment screw is installed in grain header fans entrance side faces at both ends, and air-flow plate can slide along slotted hole.
