Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bulk grain flow equipment, and particularly relates to a bulk grain flow equipment with a material control gate. Background Art
[0002] During the operation of bulk grain flow equipment, bulk grain enters the bucket elevator through a long chute with a high drop. The flow rate of the bulk grain at the outlet of the chute is fast, which causes a large impact on the downstream bucket elevator, resulting in a high crushing rate of the bulk grain. At the same time, it causes the downstream bucket elevator to operate unstably, and the buckets of the bucket elevator wear quickly. In addition, in case of an emergency stop, the bulk grain in the chute will accumulate at the feeding place of the downstream bucket elevator, affecting the restart of the bucket elevator. For bulk grain flow equipment, from the upstream process to the downstream bucket elevator, some processes have a large drop due to installation conditions. The bulk grain in the upstream process falls to the downstream bucket elevator through a chute with a large drop, and there is no device to slow down the flow rate of the bulk material. The flow rate of the bulk grain is fast, and the bulk grain impacts the bucket elevator in the downstream process.
[0003] In the prior art, when bulk grain falls to the bucket elevator through a long chute with a large drop, the following adverse effects are mainly caused: ① When the bulk grain passes through the turning point of the chute, the material flow will deviate from the center of the chute, and the bulk grain enters the bucket elevator with uneven distribution, resulting in belt deviation of the bucket elevator and a decrease in the filling rate of the buckets, affecting the safe operation and working efficiency of the bucket elevator. ② During operation, in case of an emergency stop, the bulk grain in the chute accumulates at the bottom of the bucket elevator, causing the bucket elevator to be blocked during restart, and it is necessary to clean the accumulated material at the bottom of the bucket elevator before it can be restarted. ③ The bulk grain has a large drop and a high flow rate, and the bulk grain impacts the buckets and the chute greatly, accelerating the wear of the chute and the buckets, and the crushing rate of the bulk grain is high, resulting in waste of grain or difficulty in storing the crushed grain. Summary of the Utility Model
[0004] In view of this, it is necessary to propose a bulk grain flow equipment with a material control gate to overcome several shortcomings in the above background art and solve the technical problem of how to avoid the bulk grain impacting the bucket elevator in the downstream process due to the too fast flow rate of the bulk grain in the long chute.
[0005] To achieve the above object, the utility model adopts the following technical solutions:
[0006] The present utility model provides a bulk grain flow equipment with a material control gate, which includes a bulk grain chute with a height difference at the inlet and outlet extending from the upstream to the downstream of the equipment, a bucket elevator, a material control gate device and a PLC controller arranged below the lower port of the bulk grain chute. The PLC controller is electrically connected to the bucket elevator and the material control gate device respectively. The material control gate device is installed at the inlet of the bucket elevator, and is used to control the flow rate of the bulk grain from the bulk grain chute into the inlet of the bucket elevator. The material control gate device includes a guide rail frame, a plate-shaped gate and a driving mechanism. The plate-shaped gate is pulled and pushed within the guide rail of the guide rail frame, and is used to open the inlet of the bucket elevator. The driving mechanism is used to pull and push the plate-shaped gate, and is electrically connected to the PLC controller. The bulk grain flow equipment further includes at least three capacitive material detection sensors, each of which is installed on the bulk grain chute and arranged at intervals along the length direction of the bulk grain chute. The detection head of the capacitive material detection sensor penetrates the pipe wall of the bulk grain chute, and is used to detect whether there is bulk grain within a certain distance range. The PLC controller is electrically connected to each capacitive material detection sensor respectively.
[0007] Further, at least one capacitive material detection sensor is provided in the upper section, middle section and lower section of the bulk grain chute.
[0008] Further, the driving mechanism is a cylinder, the telescopic rod of the cylinder is connected to the plate-shaped gate, and the cylinder is electrically connected to the PLC controller.
[0009] Further, the bulk grain chute is a circular hollow pipe.
[0010] Further, the guide rail frame is provided with a plurality of virtual plate edge points; the virtual plate edge points are virtual intersection points between the side edge of the plate-shaped gate and the guide rail frame.
[0011] Further, when the end point of the side edge of the plate-shaped gate is located at one of the virtual plate edge points, the distance between the side edge of the plate-shaped gate and the inner side edge of the guide rail frame is 15 cm - 20 cm, that is, when the end point of the side edge of the plate-shaped gate is located at one of the virtual plate edge points, the opening width between the guide rail frame and the side edge of the plate-shaped gate is 15 cm - 20 cm.
[0012] The beneficial effects of the present utility model are:
[0013] The utility model uses a section of bulk grain chute pipe above the bucket elevator as a buffer chute pipe, and uses a plurality of capacitive material detection sensors with height intervals installed on the bulk grain chute pipe to detect the situation of bulk grain in the bulk grain chute pipe, so that the plate gate has a certain opening and closing distance. In the normal working state, the bulk grain surface is kept between the high material level and the low material level of the buffer chute pipe. When discharging, the bulk grain fills the gate, and zero-speed discharging starts from the gate, with uniform and stable cloth feeding, effectively increasing the filling rate of the buckets of the bucket elevator, ensuring the conveying capacity, preventing the belt from running off due to uneven cloth feeding at the same time, and improving the safety of the bucket elevator; the utility model can slow down the flow rate of the bulk grain outlet, solve the adverse impact on the bucket elevator downstream of the process caused by the fast flow rate of the bulk grain, and reduce the grain breakage rate.
