Description

Counting device for sower

The utility model relates to a kind of sower counting device.

At present, the various sowers that China produces do not have counting device, can't achieve one's goal when needs are checked situations such as sowing unit workload and examination unit operating efficiency in the use, can not in time reflect the unit sowing area.Calculate by the land area of measuring or carry very much after generally will waiting until number end of job entirely according to meter, can not reflect the nuclear clear group amount of sowing on the same day like this, can not in time reflect unit fuel consumption and workload, therefore, cause situations such as real work amount and sowing record area are not inconsistent easily, influence the accuracy of statistical data.In addition, sowing crew and sowing field quality control personnel also press for and a kind ofly can measure sower operation distance whenever and wherever possible, are convenient to understand the amount of seed metering (seeding quantity) in the certain distance, change with conventional approach artificial, that wooden rule is measured.

Problem at prior art exists provides a kind of manufacturing simple in structure, easy, and reliable operation is not influenced by environment, Changes in weather, and measurement data is accurate, and high efficiency is easy to maintenance, and adaptability is strong, can be used for the counting device on all kinds of tillers.

The utility model is achieved by following manner: a kind of sower counting device, comprise support and transmission thereof, clutch, counting, resetting-mechanism five parts, it is characterized in that: said transmission mechanism, comprise drive sprocket that is connected with the sower land axle and the driven sprocket that drives by chain, wherein driven sprocket is arranged on the driving shaft left end of counting mechanism part.Said clutch, by the driving ratchet that is arranged on the driving shaft of driven sprocket right side, driven ratchet and clutch spring and be arranged between driving ratchet and driven ratchet and the crank that separates that the fork of their clutches of controlled and fork lower end are provided with is formed wherein separate crank and can rotate up and down and fork is closed driving ratchet with driven ratchet or separate.Said counting mechanism, by driving shaft and on driving gear, counter wheel, the driven shaft that driving shaft is provided with below and go up to be provided with and constitute with the idler gear of driving gear engagement and carry gear and spacer sleeve thereof, wherein five structures of counter wheel employing are identical is called the 1st, 2,3,4,5 grades counter wheel, they are followed successively by a position, ten, hundred, kilobit, the myriabit counter wheel, the carry gear adopts then that four structures are identical to be called the 1st, 2,3,4 carry gears, idler gear left side and driving gear engagement, its right side and the 1st grade of (individual position) counter wheel left side engagement, corresponding the 1st grade of counter wheel right side and the engagement of the 1st carry gear left side, then mesh with the 2nd grade of (ten) counter wheel left side on the 1st carry gear right side, and the rest may be inferred.Said resetting-mechanism, by being arranged on reduction frame on the support, resetting and separate the reseting handle that pivoted arm, reduction frame axle and right-hand member thereof are connected, the push pedal that resets that the number with counter wheel that evenly is provided with on the reduction frame axle is identical is formed, and the peach shape tooth cooperation that resets that sets in advance on wherein reset push pedal and the counter wheels at different levels engages.

Saidly at different levelsly (comprise the 1st, 2,3,4,5 grades) counter wheel evenly is provided with 20 cylin-drical tooths along its circumferencial direction, numeral of per two between cog mark, just be 0,1,2,3,4,5,6,7,8,90 numerals, only be provided with two identical cylin-drical tooths of tooth pitch on its right side circumference, evenly be provided with four and eight identical cylindrical long teeth respectively with each carry gear left side and the right side of counter wheel engagements at different levels, when the 1st grade of counter wheel rotates a circle, four cylindrical long teeth that two cylin-drical tooths on its right side are stirred the 1st carry gear left side rotate a tooth pitch, eight cylindrical long teeth on the 1st carry gear right side then rotate two tooth pitches, corresponding the 2nd grade of counter wheel with the engagement of the 1st carry gear right side also rotates the i.e. numeral (because of numeral of per two between cog mark) of two tooth pitches, so the length that previous stage count number wheel rotates is the decimal system relation of 10 times of back one-level counter wheels.

The return-to-zero mechanism course of work and principle: when promoting reseting handle, reduction frame begins outside rotation, separating pivoted arm by resetting separates with the carry gear idler gear with counter wheels at different levels, at this moment counter wheels at different levels can freely rotate on driving shaft, the push pedal that resets this moment is close to the peach type flank of tooth that resets that counter wheels at different levels are equipped with projection, the working face geometric shape of push pedal owing to reset, have only the peach type tooth bottom surface that resets with counter wheels at different levels to be combined into the tightest fixed position, therefore make counter wheels at different levels under reset push pedal and promotion, freely forward to and the same position of push pedal that reset in conjunction with the best, this position indicates " 0 ", unclamp reseting handle, each carry gear is got back to original position and counter wheel at different levels engagement again, thereby finishes (or claiming return-to-zero) effect that resets.

Characteristics such as the utility model is compared with prior art, has simple in structurely, makes easily, and reliable operation is not influenced by environment, Changes in weather, and measurement data is accurate, and high efficiency is easy to maintenance, and adaptability is strong.
