Description

Technical Field

[0001] The invention relates to the technical field of bait placing, in particular to a bait placing device for shrimp farming in rice fields. Background Art

[0002] Paddy field aquaculture is an ecological aquaculture model that carries out a virtuous cycle in the paddy field ecosystem based on the principles of ecological economics. Paddy field shrimp farming is a type of paddy field aquaculture. According to the characteristics of freshwater crayfish being suitable for growth in paddy fields, rice is planted and freshwater crayfish are raised in paddy fields, achieving an efficient production model that improves the production efficiency of paddy fields. In the process of paddy field shrimp farming, it is necessary to regularly put bait into the paddy fields to ensure the normal growth of shrimp seedlings. During the May plague period, the bait used for crayfish is generally a mixture of soybeans, granular feed and palatable auxiliary additive calcium tablets. After the feed is mixed, the workers use a transport vehicle to transport it. When it arrives at the paddy field area, the feed is fed by artificially throwing the bait. This method of feeding requires a large range of walking in the shrimp paddy field to complete the feeding of the waters in the shrimp paddy field, which is labor-intensive.

[0003] The Chinese utility model patent with announcement number CN218354101U discloses a shrimp-rice field shrimp fry bait delivery device, which includes a box body, a plurality of column feet are arranged at the bottom of the box body, a guide pipe is connected to the top of the box body, a collecting pad is fixedly connected to the inside of the box body, an arc-shaped through groove is opened on the top of the collecting pad, a feed frame is fixedly connected to the inside of the box body, and the top opening of the feed frame is directly opposite to the bottom opening of the arc-shaped through groove, a lifting mechanism for limiting the discharge of bait from the collecting pad is arranged on the top of the feed frame, a feed pump is assembled inside the box body, and the feed end of the feed pump is connected to the bottom end of the feed frame through a conduit, a hose is fixedly connected to the front of the box body, and the discharge end of the feed pump is connected to the hose through a conduit, and the side end of the hose is connected to a spray pipe, thereby facilitating the user to scatter bait on the shrimp-rice field, and the bait is led out by the feed pump to effectively ensure the range of bait spraying, and at the same time, the area of ​​bait spraying in the shrimp-rice field can be guaranteed by coordinating the angle and height of the spray pipe by the user. This patent uses the coordination between a feed pump, a hose, and a duct to automatically discharge feed into the rice field area, but workers still have to hold the hose to adjust the feed discharge position, and the convenience of feeding is still poor.

[0004] The Chinese utility model patent with the announcement number CN220359934U discloses a shrimp-rice-field shrimp fry bait delivery device, including a storage box, the front side of the lower end of the storage box is rotatably connected to a roller 1, the rear side of the lower end of the storage box is symmetrically fixedly connected to a feeding port, the lower end of the storage box is located at one side of the lower end of the feeding port and is rotatably connected to a rotating rod, the outer side of the rotating rod is fixedly connected to a feeding trough, the feeding trough is located below the feeding port, and a gear is fixedly connected to the rotating rod on one side of the feeding trough; the rear side of the lower end of the storage box is located between the feeding ports and is fixedly connected to a fixed rod, the lower end of the fixed rod is inserted with a roller 2, the upper end of the roller 2 is located inside the fixed rod and is fixedly connected to toothed plates on both sides, and the toothed plates are meshed with the gears. The utility model is designed with a feeding trough and a feeding port, and the user can pressurize the upper end of the roller 2 to insert into the fixed rod during the pushing process so that the feeding trough can open the feeding port for feeding, and the user can complete the feeding during the pushing process, which is more convenient to operate and more efficient.

[0005] However, the above patent still has the following shortcomings in actual use: 1. This patent allows the bait to be automatically discharged from the storage box by opening the feed port, and the user can complete the feeding process while pushing. As we all know, crayfish feed in the shallow water area at the edge of the rice field, so the bait needs to be put into the shallow water area at the edge of the rice field. However, the width of each road between rice fields is different, and the soil on the edge of the road is often relatively soft, which causes the storage box to be unable to move along the edge of the road, and the length of the feed chute cannot be adjusted, so it cannot be guaranteed that the bait discharged from the feed port can just fall into the shallow water area; 2. Once the feed chute of the patent is opened, the feed is continuously discharged outward, and the feed is laid in the shallow water area of ​​the rice field along the moving direction of the storage box, which causes excessive feed to be put in, resulting in feed waste. Summary of the invention

[0048] Furthermore, the abutment member 86 includes a connecting rod 861 and an abutment rod 862, a positioning screw 863 is provided on one side wall of the connecting rod 861, a positioning nut 864 is screwed on the positioning screw 863, a telescopic groove 865 which slides with the connecting rod 861 is provided at the tail end of the abutment rod 862, a moving groove 866 for the positioning screw 863 to move is provided on the outer wall of the abutment rod 862, the head end of the abutment rod 862 is hemispherical, a force block 541 is provided in the middle of the rocker arm 54, and an abutment wedge surface 5411 which abuts with the head end of the abutment rod 862 is provided on the force block 541.

[0049] First, move the telescopic block 852 toward the other end of the third rotating shaft 431, and the telescopic block 852 can be inserted into the insertion groove 4311. The telescopic block 852 is fixed to the insertion groove 4311 of the third rotating shaft 431 by means of the fixing screw 851 and the fixing nut 853. The guide groove 8111 and the guide bar 855 can allow the telescopic block 852 to stably transmit the driving force to the fourth rotating shaft 811. Then, the mobile vehicle plate 2 continues to move, and the third rotating shaft 431 can transmit the driving force to the fourth rotating shaft 811. The fourth sprocket 812 and the fifth sprocket 813 on the fourth rotating shaft 811 both rotate synchronously therewith. The fourth sprocket 812 drives one of the sixth sprockets 843 to rotate through the chain. The wheel 843 drives the corresponding linkage disk 842 and linkage shaft 841 to rotate, and the connecting piece 85 on the linkage disk 842 also rotates around the axis of the linkage shaft 841, and the head end of the abutment rod 862 gradually abuts against the abutment wedge surface 5411 of the force block 541, and the abutment rod 862 squeezes the force block 541, and the force block 541 transmits the abutment force to the swing rod 54, and the swing rod 54 rotates around the axis of the swing shaft 53. The bottom of the swing rod 54 squeezes the arc-shaped abutment bar 56 to retract into the arc-shaped installation frame 52, and the first spring 521 is compressed. The cooperation between the stabilizing shaft 561 and the stabilizing bar groove 522 can improve the stability of the arc-shaped abutment bar 56 when it moves, and the feeding frame 55 also tilts with the swing rod 54, and the shield 5 51 can increase the height of the head end of the feeding frame 55 and reduce the probability of the bait accidentally falling out of the feeding frame 55. After the head end of the abutment rod 862 is separated from the abutment wedge surface 5411, the elastic force of the first spring 521 can drive the arc-shaped abutment strip 56 to extend rapidly in the arc-shaped mounting frame 52. The arc-shaped abutment strip 56 transmits the extending force to the swing rod 54, and the swing rod 54 rotates in the opposite direction around the axis of the swing shaft 53. The swing rod 54 drives the feeding frame 55 to rotate in the opposite direction synchronously. After the swing rod 54 hits the blocking rod 512, the bait in the feeding frame 55 can be separated from the inside thereof, that is, the bait forms a throwing operation, that is, the first throwing mechanism 5 completes the throwing operation, and then the swing rod 54 and the feeding frame 55 are reset by their own gravity, and the swing rod 54 The bottom outer wall contacts the arc-shaped abutment bar 56 again, and the fifth sprocket 813 drives another fifth sprocket 813 and the sixth rotating shaft 831 to rotate through the chain. The gear 832 on the sixth rotating shaft 831 drives another gear 832 to rotate in the opposite direction, and the other gear 832 drives the fifth rotating shaft 821 to rotate in the opposite direction, and the fourth sprocket 812 on the fifth rotating shaft 821 also rotates accordingly. The fourth sprocket 812 also drives the corresponding sixth sprocket 843 to rotate in the opposite direction through the chain, and then the bait in the other feeding frame 55 can also be thrown out. The working principle of the second throwing mechanism 6 is the same as that of the first throwing mechanism 5. The two feeding frames 55 can throw bait at the same time or staggered.

[0050] The distance of bait casting is determined by the depth of the arc-shaped abutment strip 56 retracted into the arc-shaped mounting frame 52, that is, the longer the total length after the abutment rod 862 is connected to the connecting rod 861, the longer the path length of the abutment rod 862 abutting on the abutment wedge surface 5411, and the deeper the arc-shaped abutment strip 56 is retracted into the arc-shaped mounting frame 52, and the farther the bait is cast. By loosening the positioning nut 864, the abutment rod 862 can be unlocked, the abutment rod 862 can move freely, and the total length of the abutment rod 862 after being connected to the connecting rod 861 can be changed. In order to facilitate the adjustment of the abutment rod 862, a scale can be set on the outer wall of the connecting rod 861. After adjusting the abutment rod 862, the positioning nut 864 can be directly tightened.

[0053] After the fourth rotating shaft 811 and the fifth rotating shaft 821 rotate, the eighth sprocket 814 on the fourth rotating shaft 811 also rotates accordingly, and the eighth sprocket 814 on the fifth rotating shaft 821 also rotates accordingly, and the eighth sprocket 814 drives the seventh sprocket 732 to rotate through the chain, and the seventh sprocket 732 drives the seventh rotating shaft 731 and the abutting rod 733 to rotate, and the abutting rod 733 gradually approaches the second wedge surface 723, and then the abutting rod 733 squeezes the cross bar 72 through the second wedge surface 723 to move toward the closing cover 71 in the transverse groove on the L-shaped seat 121, and the third spring 741 is compressed, and the first wedge surface 721 at the head of the cross bar 72 squeezes the outer wall of the closing cover 71, and the first wedge surface 721 and the outer wall of the closing cover 71 are pressed together. The wedge surface cooperates to make the closing cover 71 move downward, and the closing cover 71 drives the two rods to move downward synchronously, the two second springs 714 are compressed, the outlet of the discharge pipe 12 is opened, the bait is discharged from the discharge pipe 12 and falls into the feeding frame 55, and after the abutment rod 733 is separated from the second wedge surface 723, the third spring 741 drives the cross bar 72 to move in the opposite direction through elastic force, and the limiting protrusion 722 can limit the position of the reverse movement of the cross bar 72, and the elastic force of the second spring 714 drives the limiting plate 713 to move upward, and the limiting plate 713 drives the guide rod 712 and the closing cover 71 to move upward, so that the closing cover 71 can re-close the discharge pipe 12, so that the feeding frame 55 can fall into a certain amount of bait.

[0054] It is worth noting that when the bait is discharged into the feeding frame 55, the bait may accidentally fall, and the fallen bait can fall into the collection inner groove 25 and be collected, thereby avoiding waste of bait.
