Description

Intelligent breeding locust suction machine

technical field

The invention relates to the field of movable equipment for catching insects, in particular to an intelligent breeding locust sucking and catching machine, which is mainly suitable for sucking and collecting locusts in breeding.

Background technique

Due to the high nutritional value of locusts, locust breeding has gradually emerged in recent years and has gradually become the first choice of farmers. However, with the continuous development of locust breeding technology and the continuous expansion of breeding scale, traditional net bags and suction devices have been far away. Can't meet actual suction and collection demand. For this reason, people once designed locust sucking and catching machine, disclosed a kind of " network shed breeding locust sucking and catching machine " as authorized announcement number for CN201270733Y, and it is mainly made of suction nozzle, feed conveying pipeline, cyclone type separating device, impeller type It is composed of closed air unloading device, collection box, three-phase asynchronous motor, centrifugal induced draft fan, exhaust pipe, AC motor, reducer, control electric box, trolley, etc. It uses a three-phase asynchronous motor as the power to drive the centrifugal fan to work. The air inlet of the fan is connected to the outlet of the cyclone separation device through the exhaust pipe, and the suction nozzle is connected to the inlet of the cyclone separation device through the feeding conveying pipe. The size of the impeller is controlled by the damper, the rotation of the impeller of the impeller type air-closed unloading device is driven by the AC motor through the reducer, and the start and stop of the three-phase asynchronous motor and the AC motor are controlled by the control electric box. Although this locust sucking machine can replace manpower work. However, it has the following defects. Since the collection process only uses a separation cylinder and a collection box, the isolation and collection measures are relatively weak. Therefore, in the actual work process, the locusts in the collection box are easily blown away with the airflow, which seriously affects the work efficiency. with the collection rate. Once a large number of locusts enter the motor, it will also cause the fan to crash and be damaged. In addition, because it only adopts an overly simple collection and separation device, it is impossible to know the amount collected in the collection box, which is extremely inconvenient to use. The function is too single to adapt to large-scale adsorption, collection and screening. Therefore, in order to solve the problems referred to above, the inventor has designed a kind of intelligent breeding locust sucking and catching machine.

Contents of the invention

The purpose of the present invention is to provide an intelligent farming locust sucking and catching machine, which fundamentally solves the problems of low trapping efficiency, poor stability, single function, and too frequent manual intervention in existing locust sucking and catching devices. It is more intelligent, which not only effectively improves the efficiency of locust suction and capture, simplifies the process of suction and capture, but also greatly avoids manual intervention.

The technical scheme adopted in the present invention is: the intelligent farming locust sucking and catching machine includes a sucking mechanism, a separation box, an isolation mechanism, a collection box and a centrifugal fan connected with the separation box, and the suctioning mechanism includes a hard suction pipe and is arranged on The suction head assembly at the end of the hard suction tube, the other end of the hard suction tube is connected to the separation box through the feeding hose, the discharge port of the separation box is connected to the isolation mechanism, and the discharge port of the isolation mechanism is connected to the collection box. The technical points Yes: the suction head assembly is composed of a central suction head and several side suction heads arranged in the circumferential direction; there is an elbow between the feed hose and the separation box, and the elbow is formed by an upper baffle with a rotation angle of 75° , a lower baffle with a rotation angle of 60°, and two parallel side baffles; the isolation mechanism includes a cylindrical isolation box shell, an isolation box shaft arranged on the axis of the cylindrical isolation box shell, and an isolation box shaft The connected isolating motor, the cross-shaped distribution fixed on the rotating shaft of the isolating box, and the blades extending axially along the cylindrical isolating box shell and the outer edge of the blade just touch the inner wall of the isolating box shell, and the bottom of the collecting box is provided with a screening mechanism. The screening mechanism includes a screen whose mesh is smaller than the length of the locust body, a fixed shaft arranged in the middle of the screen, and a movable shaft hinged at one end of the screen. connected.

Preferably, the isolation motor, the screening motor and the centrifugal fan are connected to the output end of the AVR single-chip microcomputer.

As a further preference, the screening mechanism is provided with a pressure sensor and an infrared sensor connected to the input end of the AVR single-chip microcomputer, and a display screen connected to the output end of the AVR single-chip microcomputer.

The advantages and positive technical effects of the present invention are: to integrate the suction, collection, screening, weighing, and display of the mechanical collection, firstly, according to the size of the locust, select a suction mechanism with a suitable caliber (usually 10cm), and the present invention selects Multiple suction heads catch at the same time, the middle suction head is used to catch locusts on the ground, and the side suction heads can catch locusts in flight or on the side wall at will, which expands the suction area and improves the suction speed. Then, under the action of the negative pressure generated by the centrifugal fan, the locusts enter the elbow from the suction nozzle with the airflow, the cross-sectional area suddenly increases, the speed decreases, and the direction is turned downwards after being blocked by the curved baffle, which is beneficial to the settlement of the locusts. Under the action of horizontal wind and its own gravity, the locusts move in a parabola to realize the separation of the locusts in the separation box, avoiding the disadvantages of the direct connection between the hose and the separation box, the length of the horizontal pipe is difficult to control, and it is not conducive to the separation and settlement of the locusts. So as to achieve the best separation and sedimentation effect. Then, the locusts enter the isolation mechanism, which adopts closed air isolation to ensure the stability of the negative pressure in the separation box, which is conducive to the rapid absorption and capture of locusts. At the same time, the isolation motor drives the cross-shaped blades to rotate continuously, preventing the airflow in the collection box from rising, and accelerating the settlement and collection of locusts. After the locusts arrive at the collection box, the screening motor drives the connecting rod structure to make the screen move quickly left and right to sieve out the sundries mixed in the locusts. While sifting out, the sucked locusts are weighed by the pressure sensor, then transmitted to the AVR microcontroller, and output to the display screen through AD. For the locusts in different area densities, the single-chip microcomputer regulates the speed of the centrifugal fan, isolation motor and screening motor, making the equipment more energy-saving and environmentally friendly.

To sum up, the present invention utilizes the principle of negative pressure generated by the centrifugal fan, through the feedback of the pressure sensor, avoids the overload of the collection box, and adopts the isolation mechanism to improve the efficiency of suction and capture. The multi-suction head suction mechanism is adopted, which can be applied to different suction environments and improve the suction efficiency.
