Abstract

The invention discloses an automatic accurate-rationing feeder for pigs. A storing tank, a single-chip-microcomputer electric cabinet assembly and a motor D are mounted on a frame. The storing tank is provided with a feed hopper, a discharge port and distribution hoppers. A spiral-auger conveying shaft assembly is mounted in the storing tank. Weighing tanks, draining tanks, discharger shells and feeding bunks are sequentially arranged below the distribution hoppers from top to bottom in a communicated mode. Accurate pig weighing devices are arranged on the outer side portions of the feed bunks. Each weighing tank is mounted through supporting of four pressure sensors. Upper rack-shaped push-pull retaining plates driven by motors A are mounted on the distribution hoppers. Forward-motor-rotation limiting switches A and backward-motor-rotation limiting switches A are mounted on the side portions of the outer ends of the upper rack-shaped push-pull retaining plates. Lower rack-shaped push-pull retaining plates which are driven by motors B and matched with forward-motor-rotation limiting switches B and backward-motor-rotation limiting switches B are mounted on the lower side portions of the weighing tanks. The automatic accurate-rationing feeder has the advantages of scientific feeding, novel and reasonable structural design, high automation degree and safety and reliability in use.

Embodiment

Below in conjunction with accompanying drawing, the invention embodiment is described in detail.One boar searches for food with the true restricted feeding machine of automatic precision, on frame 11 upper ends and outside portion, be equipped with respectively material box 8, motor D 19 and single-chip microcomputer electric cabinet assembly 10, feed hopper 6 and discharge port 18 are separately positioned on material box 8 feeding end and outlet sides, equipped screw auger conveying axis assembly 7 rotationally in material box 8 casees, described screw auger conveying axis assembly 7 is connected with motor D 19, a minute hopper 3 is installed on material box 8 positions, bottom side, described minute 8 casees interior connections of hopper 3 and material box, on minute hopper 3, install by motor A 4 and drive the upper rack shape pull block plate 5 of controlling, at upper rack shape pull block plate 5 outer end sidepieces successively equipped motor forward limit switch A 1 and the motor reversal limit switch A 2 being mated, below minute hopper 3, by four pressure sensors 20, support weight box 16 is installed, described four pressure sensors 20 are configured in respectively weight box 16 four corners position places, upper end, on weight box 16 following sides, install by motor B 9 and drive the lower spline-simulating pull block plate 15 of controlling, at lower spline-simulating pull block plate 15 outer end sidepieces successively equipped motor forward limit switch B 13 and the motor reversal limit switch B 12 being mated, hopper 17 and feed bunk 23 are leaked in the configuration being interconnected successively below weight box 16, leaking the interior equipped removal device housing 21 of hopper 17, the discharge rotating shaft 25 that is laid with axial notch 24 on surface is installed in rotation on removal device housing 21, motor C 14 is connected with discharge rotating shaft 25, at feed bunk 23 outside portion configuration pig body weight precise weighing devices 22, wire by single-chip microcomputer electric cabinet assembly 10 respectively with motor just, reversion limit switch A, A 1, 2, motor A, B, C,

D

4, 9, 14, 19, motor just, reversion limit switch B,

B

13, 12, pressure sensor 20, pig body weight precise weighing device 22 is communicated with.

The course of work is as follows, feed while starting, feed link is crossed feed hopper 6 and is fed material box 8, start the power knob of single-chip microcomputer electric cabinet assembly 10, send signal control motor D 19 and drive 7 rotations of screw auger conveying axis assembly, the undue hopper 3 of feed link enters weight box 16, pressure sensor 20 reaches setup pressure value, motor A 4 is rotated in the forward and drives upper rack shape pull block plate 5 to close, when upper rack shape pull block plate 5 touching motor forward limit switch A 1, motor A 4 stalls, motor B 9 reverse rotations simultaneously drive lower spline-simulating pull block plate 15 to open, upper rack shape pull block plate 15 touching motor reversal limit switch B 12, motor B 9 stalls, feed falls into Lou hopper 17, motor C 14 drives discharge rotating shaft 25 rotations with axial notch 24 that are positioned at removal device housing 21, feed falls into feed bunk 23, motor C 14 stalls, motor B 9 is rotated in the forward and drives lower spline-simulating pull block plate 15 closures, motor B 9 stalls when it touches motor forward limit switch B 13.Now, because a small amount of feed first dropping into guarantees pig feed, when the accurate weighing apparatus 22 of pig body reaches steady-state value, now weight average value is pig body weight, single-chip microcomputer electric cabinet assembly 10 calculates and records the scale of feeding of every pig, and motor D 19 drives 7 rotations of screw auger conveying axis assembly, and pressure sensor 20 reaches the value of feeding, upper rack shape pull block plate 5 is closed, and lower spline-simulating pull block plate 15 is opened.By the rate pattern of feeding, in conjunction with the volumeter of axial notch 24, calculate angular speed and the duration of runs of discharge rotating shaft 25, motor C 14 runnings, corresponding time stall.As upper rack shape pull block plate 5 touching motor forward limit switch A 1, motor D 19 postpones Preset Time, material box 8 residual feeds is drawn off to motor 19 stalls by discharge port 18.When motor C 14 stall, upper rack shape pull block plate 5 is opened, and lower spline-simulating pull block plate 15 is closed, and machine reaches original state, and work completes, powered-down button.
