Specific embodiment

The present invention is described in further detail below in conjunction with embodiment given by attached drawing.

Shown in 5, a kind of marine organisms harmful substance of the present embodiment detects weighing device, including for putting The cutting agency of marine organisms powder and the Weighing mechanism 2 being arranged in below cutting agency are set, the Weighing mechanism 2 is electronics Claim, including the pallet 21 being arranged on title body 22 that claims body 22 and can slide up and down, cutting agency is arranged in the pallet 21 Lower section, the cutting agency include for storing the hopper 11 of marine organisms powder, being arranged in hopper 11 and determine Feed device is measured, the pallet 21 is arranged in below the discharge port of hopper 11, wherein quantitative material feeder will be quantitative to be stored up Marine organisms powder in funnel 11 is transported on pallet 21 from discharge port, and the title body 22 is coupled with quantitative material feeder, Powder weight signal on pallet 21 is transmitted to quantitative material feeder, there is weight threshold in the quantitative material feeder, when When the powder weight of pallet 21 reaches weight threshold, quantitative material feeder stops feeding, and the quantitative material feeder includes opening up In the chute feeder 3 declined towards discharge port spiral, lower end and the discharge port phase of the chute feeder 3 on the inner wall of hopper 11 It is intercommunicated, push plate 4 and baffle 5 are equipped in the chute feeder 3, the inner wall of the hopper 11 is equipped with for driving push plate 4 The driving assembly 6 slid back and forth in chute feeder 3 so that push plate 4 close to or far from baffle 5, by marine organisms powder from Chute feeder 3 pushes baffle 5 to relative to the other end of discharge port, and being sticked on the inner wall of the hopper 11 has funnelform cover board The inner wall of a, the outer wall and hopper 11 of the cover board a fit closely, the slot to cover the notch of chute feeder 3, with chute feeder 3 Bottom and cell wall and push plate 4 and baffle 5 constitute a closed space, and the one side of the push plate 4 towards baffle 5 is passed equipped with pressure Sensor, it is interior with threshold value for the pressure sensor, and couples with driving assembly 6, when the pressure that pressure sensor detects is super When crossing threshold value, driving assembly 6 drives push plate 4 far from baffle 5, and the slot bottom of the chute feeder 3 is close to storing mouth and relative to baffle 5 Position on offer telescopic chute 111,5 part of baffle is embedded in telescopic chute 111, and the slot bottom of the telescopic chute 111 is set The telescopic component 7 for thering is driving baffle 5 to slide back and forth in telescopic chute 111, so that baffle 5 is extend into chute feeder 3 or retraction Into telescopic chute 111, be laid with line of codes 8 in the chute feeder 3, the driving component 6 and telescopic component 7 with line of codes 8 Coupling, have in the line of codes 8 with the one-to-one encoded radio of external position, when 4 present position of push plate is in selected coding The position of value, when pressure sensor detects that pressure is more than threshold value, telescopic component 7 drives baffle 5 to be retracted into telescopic chute 111, Driving assembly 6 drives push plate 4 to shift discharge port onto, and the marine organisms powder between push plate 4 and baffle 5 is output to pallet 21 On, it is recorded during use firstly the need of to the encoded radio on line of codes 8, concurrently sets weight threshold, as need Then the powder weight to be weighed calculates the encoded radio on corresponding line of codes 8 according to weight threshold, for example, it is assumed that 1 square Centimetre compacting powder weight be equal to 1 gram, then the section of the chute feeder 3 in the present embodiment is square structure, length and width are 1 Centimetre, according to cubature formula, volume=bottom * high * wide of cuboid, therefore, the volume of powder are after push plate 4 pushes away reality, to push away The distance between plate 4 and baffle 5 are multiplied by 1 centimetre multiplied by 1 centimetre, therefore the encoded radio of line of codes 8 can be set into 1 centimetre one A encoded radio, it can be assumed that encoded radio is respectively 0001,0011,0010,0110,0111 to respectively correspond 1 centimetre, 2 centimetres, 3 lis Rice, 4 centimetres and 5 centimetres can be by measuring formulation, after once specifying as the pressure threshold of pressure sensor in advance Just will not change, so model will be transferred in driving assembly 6 when needing to weigh 3 grams of powder, driving assembly 6 Push plate 4 will be driven to pass through ceaselessly to move back and forth, powder is constantly transported in chute feeder 3, between baffle 5, this reality It applies the baffle 5 in example and chute feeder 3 is set close to one end of discharge port, to guarantee that it is more bigger that the weight of powder of feeding has Selection, during push plate 4 pushes powder to move towards baffle 5, push plate 4 shifts powder onto and presses to baffle 5 until pressure sensing The pressure that device detects is more than threshold value, thus can effectively guarantee that after push plate 4 pushes powder each time be all for compacting State, avoid the occurrence of the powder pine nut in one section of chute feeder 3 it is uneven caused by the powder weight that finally exports do not reach and want The problem of asking, while the encoded radio of the corresponding line of codes 8 of push plate 4 when each push plate 4 is compacted is recorded, and be arranged to work as pressure sensing Device be more than threshold value, while push plate 4 position reach for need encoded radio, i.e. 3 centimetres of encoded radio 0010 when, mean that Required powder weight is weighed, the telescopic action of telescopic component 7 is utilized later, baffle 5 is retracted, bottom is shifted in push plate 4 onto, this Sample just can be good at realizing the effect on the pallet 21 that weighed powder weight is disposably transported on Weighing mechanism 2, So compared to the prior art by the way of artificial, efficiency has obtained greatly being promoted.
