Abstract

The utility model relates to a hand feed feeder which is used for breeding domestic silkworms. The utility model is characterized in that a motor is installed at the upper end of a connecting bracket. A motor shaft is connected with a screw mandrel which is positioned in the connecting bracket. Inner threads which are matched with the screw mandrel are arranged at the upper end of a hollow ejector rod. A stopping fixed pin is also fixed on the outside of the hollow ejector rod. The stopping fixed pin penetrates in an axial sliding groove of the connecting bracket. A pressing plate in a charging basket is connected with the lower end of the ejector rod. The lower part of the pressing plate is also provided with a soft pad which is made of elastic materials. A discharging die plate which is provided with shaped holes is arranged at the bottom part of the charging basket.

Description

The artificial feed batcher

The utility model relates to kind of an a kind of artificial feed batcher that is used for silkworm rearing.

Artificial feed are bred silkworms, and silkworm is already produced not restricted by weather and environmental factor, realize the batch production sericulture, are the developing direction that silkworm is already innovated technologies.The silkworm artificial feed is a semi-solid, feed comparatively the difficulty, its quality and work efficiency to silkworm grow and the recruitment cost has direct influence.Existing feed-type is a kind of to be manual operations, promptly with cutter or dish plate cubed feed is cut into strip, moves into then in the silkworm rearing bed, and efficient is very low, and moulding is irregular, and the uniformity is poor, can not satisfy needs of scale production; Another kind of mode is the mechanization feed, adopts the rotary cutter cutting feed of semiautomatic control, and this method has strict demand to the feed physical characteristic, is difficult to adapt to the low-cost artificial feed that viscosity is big, hardness is low slightly of present exploitation.

The purpose of this utility model provides a kind of charge efficiency height, steady quality, simple in structure, artificial feed feed batcher that mechanization degree is high.

The technical solution of the utility model is, this artificial feed batcher comprises main frame and control circuit, it is characterized in that, described main frame is by the motor that is installed on the link, screw mandrel, hollow push rod and charging basket are formed, motor is installed in the link upper end, motor shaft is connected with the screw mandrel that is positioned at link, hollow top stem casing is outside screw mandrel, its upper end is the internal thread that matches with screw mandrel, the hollow push rod outside also is fixed with stopping pin, stopping pin is through in the axial slide on the link, charging basket is positioned at link and push rod lower end, and a pressing plate with the charging basket matched in clearance is arranged in the charging basket, and pressing plate is connected in the push rod lower end, the cushion that elastomeric material is made also is installed under pressing plate, and the bottom of charging basket is the material discharging mould that has the moulding hole; In the described control circuit, 220 volts of AC powers output to node A and node B through transformation and current rectifying and wave filtering circuit, are serially connected with relay J between node A and the B ₂With normally closed travel switch K ₂, relay J ₁With duplex travel switch K ₁Normally-closed contact K ₁' be serially connected between node A and the node B relay J ₃, normally closed switch K ₀And duplex travel switch K ₁Normally opened contact K ₁" also be serially connected between node A and the node B relay J successively ₃Normally opened contact J ₃ ⁰With K ₁" parallel connection; The common port of described motor inserts zero-power line, and the counter-rotating end of motor is through the relay J of serial connection ₂Normally opened contact J ₂' and relay J ₃Normally opened contact J ₃' access power supply phase line, the relay J of just changeing end process serial connection of motor ₁Normally opened contact J ₁' and relay J ₃Normally-closed contact J ₃" insert the power supply phase line.

The utility model has the advantages that, simple in structure, control the feed process automatically, thereby efficient height, steady quality, and can adapt to the low-cost feed that viscosity is big, hardness is low slightly.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Fig. 1 is a main machine structure schematic diagram of the present utility model;

Fig. 2 is control circuit figure of the present utility model.

As shown in Figure 1, the main frame of this artificial feed batcher is made up of the motor 2, screw mandrel 3, hollow push rod 4 and the charging basket 7 that are installed on the link 1.Motor 2 is installed in link 1 upper end, motor shaft is connected with the screw mandrel 3 that is positioned at link, hollow push rod 4 is enclosed within outside the screw mandrel, its upper end is the internal thread that matches with screw mandrel, the stopping pin 5 in hollow push rod 4 outsides is through in the axial slide 6 on the link 1, charging basket 7 is positioned at link and hollow push rod lower end, pressing plate 8 with the charging basket matched in clearance is arranged in the charging basket, pressing plate 8 is connected in hollow push rod 4 lower ends, the cushion 9 that one deck is made by elastomeric material also is installed, in the feed process, because cushion pressurized diameter increases and closely cooperates with the formation of charging basket wall under pressing plate, prevented the feed backflow, extrude in the moulding hole 10 that feed link is crossed on the bottom template 11 of charging basket.The control circuit of this artificial feed batcher as shown in Figure 2,220 volts of AC powers output to node A and node B through transformation and current rectifying and wave filtering circuit 12 backs with direct current, relay J in parallel between node A and the node B ₁, J ₂And J ₃When main frame is in original state, promptly push rod and pressing plate are positioned at the charging basket upper end, connect power supply, J this moment ₁, J ₂Conducting and J ₃Lead to, then contact J ₁' and normally-closed contact J ₃" motor just changes for closure, the positive switch coil conducting of motor 2, and push rod and pressing plate move downward extrudes feed.When arriving lower dead center, feed has been squeezed duplex travel switch K ₁Be depressed its contact K ₁' disconnect K ₁" closure, relay J at this moment ₁Obstructed and J ₃Conducting, then contact J ₁' and J ₃" disconnect, motor 2 positive switch coils are obstructed, and contact J ₂' and J ₃' closure, the counter-rotating coil is switched on, the motor counter-rotating, push rod and pressing plate upwards return, relay J ₁Again conducting, and because relay J ₃Contact J ₃ ⁰Closed self-locking makes relay J ₃Keep conducting state.When arriving top dead centre, travel switch K ₂Be depressed, make relay J ₂Dead electricity, then contact J ₂' disconnecting, this moment, the forward and backward coil of motor 2 was all obstructed, and motor stops operating.Only press K switch this moment ₀Make relay K ₃Dead electricity just begins next circulation.
