Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
As shown in fig. 1 and 2, the multi-point grain unloading belt conveyor with stable operation comprises a conveyor body 1 and a grain unloading trolley 2 walking on the top end of the conveyor body 1, wherein a grain unloading tank 3 is arranged on the grain unloading trolley 2, and a feed inlet 31 and a discharge outlet are formed in the grain unloading tank 3; the conveyor body 1 and the grain unloading trolley 2 are sleeved with the same conveyor belt 4, the grain unloading trolley 2 is provided with a plurality of direction-changing rollers 21, and one direction-changing roller 21 is positioned at the feed inlet 31; an inductive proximity switch 22 is arranged on the grain unloading trolley 2, a plurality of inductive pieces 11 are arranged on the conveyor body 1, and the inductive proximity switch 22 can be close to each inductive piece 11 in the running process of the grain unloading trolley 2 on the conveyor body 1.
When the conveyor runs, the grain unloading trolley 2 can move back and forth on the conveyor body 1, and when the trolley runs to one grain unloading point, the inductive proximity switch 22 on the conveyor is close to the sensing piece 11 at the position, a signal is obtained, so that the grain unloading trolley 2 stops moving, and a grain unloading inquiry is sent to the control center. If the operator agrees to unload grains at the control center, the system automatically starts the conveyor belt 4, and grains can be conveyed through the conveyor belt 4. And the feed inlet 31 of the grain unloading box 3 is provided with a bend roll 21, so that the conveyor belt 4 bends at the feed inlet 31, grains on the bend roll are continuously thrown into the grain unloading box 3, and grain unloading operation is completed through the discharge outlet. If the operator operation disallows to unload the grains, the grain unloading trolley 2 continues to travel to the next grain unloading point, and the operation is repeated, so that the multi-point grain unloading operation is completed. And because the inductive proximity switch 22 has the characteristics of non-contact induction, non-contact output, high reaction speed, capability of working in the environment with water or oil splashing and the like, the inductive proximity switch can effectively avoid damage of the inductive proximity switch and other parts, has longer operation life compared with a travel switch, has better anti-interference performance and stable operation compared with a photoelectric switch, and further greatly improves the operation stability of the conveyor.
As shown in fig. 2, 3 and 4, two grain discharging hoppers 32 which are arranged in an inverted V shape are arranged at the discharge hole of the grain discharging box 3, and the two grain discharging hoppers 32 face to two sides of the conveyor body 1 respectively; the grain unloading box 3 is rotationally connected with a rotating shaft 33, a baffle 34 is fixed on the rotating shaft 33, and the rotating shaft 33 can enable the baffle 34 to block any grain unloading hopper 32; the grain unloading trolley 2 is also provided with a servo motor 23 which can drive the rotating shaft 33 to rotate. The servo motor 23 can drive the baffle 34 to turn over through the rotating shaft 33, so that the two grain unloading hoppers 32 on the grain unloading box 3 can be used in a switching mode, and therefore, the grain bins can be arranged on two sides of each grain unloading point of the conveyor, and after the grain unloading of one grain bin is completed, the servo motor 23 is only required to work through the control center, the baffle 34 is turned over, grains are unloaded into the other grain bin, and the grain unloading machine is more convenient to use.
As shown in fig. 3, 4 and 5, a dust removing box is fixed on one outer side wall of the grain unloading box 3, an air outlet is arranged on the outer wall of the dust removing box, and an air outlet fan 51 is arranged on the outer wall of the dust removing box; an air inlet 35 for conducting the grain unloading tank 3 and a dust removing tank is arranged on the side wall of the grain unloading tank 3, and a filter screen 52 which can separate the air inlet 35 from the air outlet is arranged in the dust removing tank. Because a large amount of dust is inevitably doped in the grains, dust is required to be removed synchronously during grain unloading in order to avoid the situation that the grains are unloaded and dust is excessively raised to cause environmental pollution. In the conveyor, the exhaust fan 51 on the dust removing box can continuously exhaust air outwards, so that air in the grain discharging box 3 continuously enters the dust removing box through the air inlet 35, and therefore when grains are thrown into the grain discharging box, the doped dust is brought into the dust removing box by the air and blocked by the filter screen 52 in the dust removing box, dust removing operation is completed, and the grains in the bin are cleaner and environment-friendly.
As shown in fig. 5, the dust removing box comprises a box body 53 and a cover body 54 which are hinged together, and the exhaust fan 51 is fixed on the cover body 54; the opening part of the box 53 is provided with a concave step surface, the filter screen 52 is arranged on the step surface, and the cover 54 is provided with a plurality of pressing strips 55 which can press the filter screen 52, so that the filter screen 52 is very convenient to detach and mount, the filter screen 52 can be taken out after being opened, the filter screen 52 can be mounted after being closed, and the filter screen 52 can be taken out and cleaned conveniently and conveniently, so that the use effect of the dust removal box is ensured. The box body 53 and the cover body 54 of the dust removing box are formed by dividing a cuboid into halves along a diagonal line, so that after the filter is installed, the dust removing box is divided into two chambers, and enough space is reserved between the filter screen 52 and the exhaust fan 51.
As shown in fig. 5, the filter screen 52 is obliquely arranged, and the included angle between the filter screen 52 and the horizontal plane is between 30 ° and 70 °; the bottom of the box 53 is provided with a slag collecting hopper 56 below the filter screen 52, and the bottom of the slag collecting hopper 56 is detachably connected with a cover plate 57. In addition to the dust, a small amount of straw scraps, woven bag scraps, shrunken grains and the like are sometimes doped in the grains, and the inclined arrangement of the filter screen 52 can enable the scraps in the suction dust removal box to be blocked by air, and automatically fall into the slag collection hopper 56 when the exhaust fan 51 stops working, and are collected and temporarily stored by the slag collection hopper 56. I only need to open the cover plate 57 at the bottom of the device periodically to clean the device.
As shown in fig. 4, a blocking cover 36 is arranged on the inner wall of the grain unloading tank 3 at the air inlet 35, the opening of the blocking cover 36 is downward, and the lower edge of the blocking cover 36 is positioned below the lowest point of the air inlet 35. The existence of the blocking cover 36 can effectively prevent grains thrown out of the conveyer belt 4 from directly entering the dust removing box through the air inlet 35, and impurities with smaller density can enter the dust removing box along with air flow under the condition that the air inlet 35 is continuously circulated, so as to be collected. While grains having a higher density cannot pass through the air inlet 35.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
