Abstract

The utility model relates to a barn pest sampler which comprises a certain quantity of pest catchers which are respectively connected with a periodicity strobe unit driven by a positive-negative electric motor through connecting pipes. The periodicity strobe unit is connected with a pest storer through connecting pipes, and the pest storer is connected with a negative pressure source through connecting pipes. The utility model can be used for sampling pests without opening a barn, and consequently, the barn opening frequencies are reduced, and the sampling efficiency is improved.

Description

The Grainhouse injurious insect sampler

Technical field

The utility model relates to a kind of sampler, particularly relates to a kind of device that insect in the silo is taken a sample.

Technical background

In the deposit process of grain, need often the insect situation in the silo to be carried out sample analysis, so that take appropriate measures.At present, the sampling of the insect in the silo is still the artificial sample method of employing,, counts it then one by one with manually sifting out insect.Also there is employing in silo, to place pest catcher in recent years and carries out insect sampling, as Chinese patent ZL90209011.9, ZL92102125.9 is the insect of adopting in the trap pest catcher seizure silo, extract catcher then and check number and the kind of insect, though improved sampling efficiency than preceding method, but because need extract the trap pest catcher from the some sampling spots in the silo, therefore not only still have higher labour intensity, and certainly will increase the number of times that opens a position of silo.

Summary of the invention

The purpose of this utility model provides a kind of need not opening a position can carry out the Grainhouse injurious insect sampler of insect sampling, thereby reduces the number of times that opens a position, and improves sampling efficiency.

For achieving the above object, the technical solution adopted in the utility model is: a kind of Grainhouse injurious insect sampler, the pest catcher that comprises some, each pest catcher respectively by connecting pipe be connected by positive and negative motor-driven periodicity strobe unit, this periodicity strobe unit is connected with pest storage by connecting pipe, and pest storage is connected with a negative pressure source by connecting pipe.

In order to count automatically the insect of sampling, periodically the connecting pipe between strobe unit and the pest storage is transparent tube and passes from optic coupling element.

Described periodicity strobe unit is made up of rolling disc, shaft collar, and rolling disc is contained on the motor shaft, shaft collar be provided with some be uniformly distributed along the circumference and with the corresponding to through hole of pest catcher quantity, rolling disc is provided with a through hole that can communicate one by one with through hole; Also be provided with the week light hole consistent with number of openings on rolling disc, shaft collar is provided with a breach, and light-emitting component is housed in the breach, in the light hole outside of rolling disc the photo-sensitive cell that is coupled with light-emitting component is housed.

Temperature sensor, humidity sensor and pressure transducer also are housed in the connecting pipe between negative pressure source and pest storage, solenoid valve is housed on connecting pipe.

The utility model utilizes the pest catcher in the silo to catch pests, and utilize negative pressure source the insect that captures to be drawn in the pest storage by pipeline, need not open a position and can carry out insect sampling, sampling efficiency height, and significantly reduced the number of times that opens a position, help the storage of grain.Simultaneously, after utilizing the utility model sampling, can be by analysis to a certain sampled point insect situation, in time find the active situation of a certain position insect in the silo, and this position carried out Local treatment, with compare with regard to the method that all grains in needing silo carry out medicine steaming every a period of time in traditional grain storage process, can save the consumption of insecticidal materials greatly.

Embodiment

Different mining sampling point in silo is placed the pest catcher 1 of some, so that carry out multi-point sampling.The trap pest catcher that provides as ZL90209011.9 can be provided pest catcher, and this catcher can only enter worm alive, and dead worm and impurity then can not enter, and therefore can make sampled result more accurate.Each pest catcher is connected with periodicity strobe unit 3 by connecting flexible pipe 2 respectively, and strobe unit is driven by positive and negative motor 4.This periodically strobe unit 3 form by rolling disc 19, shaft collar 16, rolling disc 19 is sleeved in the shaft collar 16 rotationally, rolling disc 19 is contained on 4 in the motor by axis hole 20.Shaft collar 16 be provided be uniformly distributed along the circumference and with the corresponding to through hole 17 of pest catcher quantity, connecting pipe 2 one ends are connected with pest catcher 1, the other end is connected with corresponding through hole 17.Rolling disc 19 is provided with a through hole 18, drives in the process of turn disc at motor 4, and through hole 18 can communicate one by one with through hole 17.Also be provided with the week light hole 21 consistent with through hole 17 quantity on rolling disc 19, shaft collar 16 is provided with a breach 22, and light-emitting component 23 is housed in the breach, in light hole 21 outsides of rolling disc 19 photo-sensitive cell 24 that is coupled with light-emitting component 23 is housed.Transparent connecting pipe 5 one ends are connected with through hole 18, and the other end is connected with pest storage 7, and connecting pipe 5 passes from optic coupling element 6.Pest storage 7 is connected with negative pressure source by connecting pipe 8.In order to prevent to enter insect in the pest storage, can web plate be set in the outlet of pest storage by negative pressure suction connection 8.Temperature sensor 9, humidity sensor 10 and pressure transducer 11 also are housed in the connecting pipe 8 between negative pressure source and pest storage 7, solenoid valve 12 is housed on connecting pipe 8.Negative pressure source is made up of vacuum pump 15 and gas bag 13, is connected by connecting pipe 14 between them.

Principle of work of the present utility model is: start vacuum pump 15 work and open solenoid valve 12, because gas bag 13 communicates with pest storage 7,7 form negative pressure in pest storage.Motor 4 is rotated, motor 4 drives rolling disc 19 and rotates, when one of them through hole 17 on the through hole on the rolling disc 18 and the shaft collar 16 when communicating, because suction function, promptly be sucked out with 1 insect in the corresponding pest catcher of this through hole by connecting pipe 2, and enter in the pest storage by through hole and the connecting pipe 5 that communicates on shaft collar and the rolling disc, promptly finish the insect sampling.In this process, insect is by transparent connecting pipe 5 time because connecting pipe is by optocoupler 6, therefore whenever from connecting pipe 5 by an insect, optocoupler 6 promptly produces an electric signal, is fed to the treatment circuit supporting with this sampler, carries out the insect counting.Simultaneously, because in the suction insect, the connecting pipe that exchanged and flow through of the gas in the silo utilizes temperature sensor 9, the humidity sensor 10 of dress connecting pipe 8 in can carry out temperature and humidity and samples.The optocoupler control that the time that a certain sampled point is sampled is made up of light-emitting component 23 and photo-sensitive cell 24, when through hole 18 communicates with through hole 17, light hole 21 is also just over against breach 22, the light that light-emitting component 23 sends is received and produces an electric signal by photo-sensitive cell 24, be fed to the treatment circuit supporting with this sampler, the time that the control motor stops operating and sets, thereby the time that control is sampled to a certain sampled point.After this point sampling end, rotate and the driving turn disc by control circuit control motor, make next through hole 17 on 18 pairs of shaft collars of through hole, thereby next sampled point is sampled.The rest may be inferred later on.
