Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to an aquaculture feed delivery device. Background Art

[0002] In the process of aquaculture, it is necessary to feed aquatic products (such as fish, shrimp, etc.) to ensure the normal growth of aquatic products. Among them, when feeding aquatic products, a feed delivery device is generally used, which can automatically deliver the feed into the breeding pond, which is very convenient.

[0003] However, the existing feed delivery devices have shortcomings. Due to the variety of aquatic products, the amount of feed required for breeding different types of aquatic products is different. Most of the existing feed delivery devices have simple structures and do not have the function of adjusting the feed delivery amount. The feed delivery amount cannot be controlled, resulting in the user being unable to adjust the appropriate feed delivery amount according to the type of aquatic products being cultured, thereby affecting the normal growth of aquatic products and reducing the output and quality of aquatic products. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an aquaculture feed delivery device capable of adjusting the amount of feed delivered.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: an aquaculture feed delivery device, including a base frame, a feeding pipe with a hollow structure arranged in the base frame, and a sealing plate for opening and closing the feeding pipe. The above-mentioned feed delivery device also includes an adjusting mechanism for adjusting the delivery amount of the feeding pipe. The adjusting mechanism includes an adjusting plate slidably arranged in the feeding pipe, and a screw rod threadedly connected to the adjusting plate. The adjusting plate is located below the sealing plate. Rotating the screw rod will threadably transmit the adjusting plate to slide open and close the feeding pipe.

[0006] In the above scheme, an adjustment plate is provided to slide inside the feed tube, and the screw is rotated to thread the adjustment plate to slide open and close the feed tube. When in use, the screw can be rotated to transmit the adjustment plate to slide, so as to adjust the offset position between the adjustment plate and the internal channel of the feed tube, so as to adjust the feed delivery amount of the feed tube, so that the user can adjust the appropriate feed delivery amount according to the type of aquatic products being cultured, ensure the normal growth of aquatic products, and improve the yield and quality of aquatic products. The screw can allow the adjustment plate to stay at any position, preventing the adjustment plate from sliding naturally in the adjusted position, and the adjustment operation is more precise.

[0007] Furthermore, the above-mentioned adjustment mechanism also includes a first tension spring. In the absence of external force, the first tension spring will pull the adjustment plate to slide in the closing direction through its own elastic force to realize the automatic closing function of the adjustment plate. The rear end of the above-mentioned adjustment plate is provided with a vertical plate, and the vertical plate is located on the outside of the feeding tube. The screw rod is threadedly connected to the vertical plate. When the front end of the screw rod abuts against the outside of the feeding tube, the screw rod is rotated at this time to thread the vertical plate to drive the adjustment plate to slide back and forth. In this way, the adjustment plate is not constrained by the screw rod, so that the user can directly pull the vertical plate to drive the adjustment plate to slide backward, so as to quickly open the adjustment plate. The first tension spring will automatically pull the adjustment plate to slide forward so that the front end of the screw rod abuts against the outside of the feeding tube, so that the adjustment plate can be fixed in the adjusted position without sliding naturally.

[0008] Furthermore, a support rod is provided between the outer side of the above-mentioned feeding pipe and the base frame at a position corresponding to the lower side of the adjusting plate, and a sliding sleeve is connected to the rear end of the adjusting plate. The sliding sleeve is mounted on the outer side of the support rod and slides with the support rod. When the adjusting plate slides, the sliding sleeve will drive the sliding sleeve to slide along the support rod, and the support rod can prevent the adjusting plate from moving downward, which can improve the sliding stability of the adjusting plate and make the structure more stable.

[0009] Furthermore, a lock is provided at the rear end of the above-mentioned sliding sleeve, and a card block is provided on the support rod. When the adjustment plate slides to a fully open state, the lock is engaged with the card block. At this time, the card block can block the lock of the sliding sleeve, thereby locking the adjustment plate in a fully open state.

[0010] Furthermore, the cross section of the feed tube is a rectangular structure, and two guide grooves are provided on the inner side of the feed tube corresponding to the position of the adjustment plate. The left and right sides of the adjustment plate are respectively inserted into the corresponding guide grooves and can slide relative to the guide grooves, so that the adjustment plate can slide along the guide grooves to open and close the feed tube, thereby ensuring the sliding stability of the adjustment plate. The first tension spring is provided with two, and the two first tension springs are respectively located on the left and right sides of the adjustment plate, and the two first tension springs are parallel to the screw rod, so that the screw rod and the adjustment plate can be balanced, and the structure is more stable. One end of the first tension spring is connected to the feed tube, and the other end is connected to the adjustment plate. In the absence of external force, the first tension spring will pull the adjustment plate to slide in the closing direction through its own elastic force.

[0011] Furthermore, the above-mentioned adjusting mechanism has multiple adjusting mechanisms, which are arranged from top to bottom, wherein the number of adjusting mechanisms can be set according to the number of breeding ponds, and the release amount of each adjusting mechanism can be pre-adjusted for the corresponding breeding aquatic products, so that the user only needs to adjust the release amount of the feed delivery device once to meet the feed feeding requirements of multiple different types of aquatic products.

[0012] Furthermore, a shield is provided at the opening position of the lower end of the feed pipe, a discharge port is provided on the side wall of the shield, a motor is provided below the outer side of the shield, a rotating blade is provided inside the shield, and the rotating blade is connected to the rotating shaft of the motor. When in use, when the feed pipe delivers the feed into the shield, the rotating shaft of the motor will drive the rotating blade to rotate, and the rotating blade will deliver the feed from the discharge port. In this way, the feed can be delivered farther and more evenly by delivering the feed through the rotating blade.

[0013] Furthermore, the sealing plate is slidably arranged inside the feeding tube, and the sliding sealing plate can open and close the feeding tube, and a second tension spring is connected to the outer end of the sealing plate. In the absence of external force, the second tension spring will pull the sealing plate to slide in the opening direction through its own elastic force, thereby realizing the automatic opening function of the sealing plate. The above-mentioned feed delivery device also includes a locking mechanism for locking the sealing plate in a closed state.

[0014] Furthermore, the locking mechanism includes a base disposed on the outside of the shield, a rotating block rotatably connected to the base, an insertion rod and a push rod disposed on the side wall of the rotating block, a fixed seat disposed on the outside of the feed pipe, a support tube, and a transmission rod disposed in the support tube. The push rod extends out of the base, and pushing the push rod drives the rotating block to rotate, and rotating the rotating block can drive the insertion rod to insert and remove from the shield. The lower end of the support tube is fixed to the outside of the base, and the upper end of the support tube is fixed to the fixed seat. The lower end of the transmission rod is connected to the rotating block, and a locking groove is provided on the side wall of the sealing plate. When the sealing plate slides to a closed state and the insertion rod is inserted into the shield, the upper end of the transmission rod extends out of the support tube and is inserted into the locking groove of the sealing plate. At this time, the upper end of the transmission rod can block the locking groove of the sealing plate, thereby locking the sealing plate in a closed state. When the sealing plate needs to be opened, the motor can be turned on to drive the rotating blades to rotate. Rotating the rotating blades will push the plug rod out of the shield, causing the rotating block to rotate to the right and pull the upper end of the transmission rod out of the locking groove of the sealing plate, thereby releasing the lock on the sealing plate. At this time, the second tension spring will automatically pull the sealing plate to slide open, making it easy to open.

[0015] Furthermore, the above-mentioned locking mechanism also includes a locking column slidably arranged in the base, the rear end of the locking column extends out of the base, a spring is mounted on the outer side of the locking column, and a positioning groove is opened on the side wall of the rotating block. When the insertion rod is out of the protective cover position, the rotating block will pull the upper end of the transmission rod out of the locking groove of the sealing plate, and at the same time, the positioning groove of the rotating block is aligned with the position of the locking column. At this time, the spring will push the front end of the locking column to be inserted into the positioning groove through its own elastic force, so that the front end of the lock column can block the positioning groove of the rotating block, thereby locking the rotating block in the position where the insertion rod is out of the protective cover, preventing the rotating block from rotating naturally and driving the insertion rod into the protective cover to affect the rotation of the rotating blade.

[0016] The beneficial effects of the aquaculture feed delivery device of the utility model are as follows: 1. The user can adjust the appropriate feed delivery amount according to the type of aquatic products being cultured, thereby ensuring the normal growth of the aquatic products and improving the output and quality of the aquatic products.

[0017] 2. The adjustment plate is not constrained by the screw rod, and can be quickly opened and locked in the open state. After the adjustment plate is unlocked, the first tension spring will automatically pull the adjustment plate to drive the front end of the screw rod to abut against the feed tube, thereby fixing the adjustment plate in the adjusted position.

[0018] 3. There are multiple adjustment mechanisms. The user only needs to adjust the feeding amount of the feed delivery device once to meet the feeding requirements of multiple different types of aquaculture ponds, saving adjustment operation time.

[0019] 4. The sealing plate can be locked in a closed state, the structure is stable, and the opening motor is driven by the rotating blade to automatically open the sealing plate, and the sealing plate is easy to open. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0032] Embodiment 1

[0033] like Figure 1 , 2 As shown, this embodiment provides an aquaculture feed delivery device, including a base frame 1, a feeding pipe 2 with a hollow structure arranged in the base frame 1, and a sealing plate 3 for opening and closing the feeding pipe 2. The feeding pipe 2 is vertically arranged in the middle of the base frame 1, and the cross section of the feeding pipe 2 is a rectangular structure. The sealing plate 3 is slidably arranged at the upper inner position of the feeding pipe 2, and the sliding sealing plate 3 can open and close the internal channel 20 of the feeding pipe 2. A pad 12 is provided on the outer side of the base frame 1 corresponding to the position below the sealing plate 3. The outer end of the sealing plate 3 extends out of the base frame 1 and is placed on the pad 12. The pad 12 can prevent the sealing plate 3 from moving downward, thereby improving the structural stability of the sealing plate 3. The pad 12 is respectively provided with L-shaped guide blocks 121 at the left and right sides of the sealing plate 3. The left and right sides of the sealing plate 3 are respectively slidably matched with the L-shaped guide blocks 121 on the corresponding sides, so that the sealing plate 3 can slide forward and backward along the L-shaped guide blocks 121 to ensure the sliding stability of the sealing plate 3.

[0034] like Figure 3 , 4As shown, the feed delivery device also includes an adjustment mechanism for adjusting the delivery amount of the feed pipe 2, and the adjustment mechanism includes an adjustment plate 41 slidably arranged in the feed pipe 2, and a screw 42 threadedly connected to the adjustment plate 41, and the adjustment plate 41 is located below the sealing plate 3. Rotating the screw 42 will thread the adjustment plate 41 to slide and open and close the feed pipe 2. In this way, the adjustment plate 41 can be driven to slide by rotating the screw 42 to adjust the offset position of the adjustment plate 41 and the internal channel of the feed pipe 2, so that the feed delivery amount of the feed pipe 2 can be adjusted, so that the user can adjust the appropriate feed delivery amount according to the type of aquatic products being cultured, ensure the normal growth of aquatic products, and improve the yield and quality of aquatic products. In addition, the screw 42 can allow the adjustment plate 41 to stay in any position, avoiding the natural sliding of the adjustment plate 41 in the adjusted position, and the adjustment operation is more precise.

[0035] When the aquaculture feed delivery device of the present embodiment is used, the offset position of the adjustment plate 41 and the internal passage of the feeding pipe 2 is first adjusted according to the type of aquatic products being cultured and the year of aquaculture to adjust the appropriate delivery amount of the feed delivery device, and then the entire delivery device is placed on the boat, and then the funnel is installed to the upper opening position of the feeding pipe 2, and at the same time, the outlet of the funnel is connected with the upper opening of the feeding pipe 2. At this time, the sealing plate 3 slides to close the position of the internal passage of the feeding pipe 2, and then the feed is poured into the funnel, and finally the sealing plate 3 is slid open, and the feed will fall from the lower opening of the feeding pipe 2 into the pond, and the feed can be delivered to every corner of the pond by moving the boat.

[0036] In addition, the upper opening of the feed pipe 2 is provided with a funnel mounting groove 21, and when in use, the lower end of the funnel can be mounted in the funnel mounting groove 21 to ensure the installation stability of the funnel. In addition, the aquaculture feed delivery device of the utility model is particularly suitable for feeding shrimp aquatic products.

[0037] Embodiment 2

[0038] This embodiment is a further improvement on the structure of the aquaculture feed delivery device of the first embodiment, and the improvement is that: Figure 3 , 4 As shown, the above-mentioned adjustment mechanism also includes a first tension spring 43. In the absence of external force, the first tension spring 43 will pull the adjustment plate 41 to slide in the closing direction through its own elastic force to achieve the automatic closing function of the adjustment plate 41. The rear end of the above-mentioned adjustment plate 41 is provided with a vertical plate 411, and the vertical plate 411 is located outside the feeding tube 2. The screw rod 42 is threadedly connected to the vertical plate 411. When the front end of the screw rod 42 abuts against the outside of the feeding tube 2, the screw rod 42 is rotated at this time to be threadedly transmitted to the vertical plate 411 to drive the adjustment plate 41 to slide forward and backward.

[0039] A support rod 11 is provided between the outer side of the above-mentioned feeding pipe 2 and the base frame 1 at a position corresponding to the lower side of the adjusting plate 41. A sliding sleeve 412 is connected to the rear end of the adjusting plate 41. The sliding sleeve 412 is sleeved on the outer side of the support rod 11 and slides with the support rod 11. When the adjusting plate 41 slides, the sliding sleeve 412 will be driven to slide along the support rod 11, thereby improving the sliding stability of the adjusting plate 41, and the support rod 11 can prevent the adjusting plate 41 from moving downward, and the structure is more stable.

[0040] The rear end of the sliding sleeve 412 is provided with a lock buckle 4121, and the support rod 11 is provided with a clamping block 111. Figure 5 , 6 As shown, when the adjustment plate 41 slides to the fully open state, the lock 4121 is engaged with the block 111, and the block 111 can block the lock 4121 of the sliding sleeve 412, thereby locking the adjustment plate 41 in the fully open state.

[0041] In addition, two guide grooves are provided on the inner side of the feed tube 2 corresponding to the position of the adjustment plate 41. The left and right sides of the adjustment plate are respectively inserted into the corresponding guide grooves and can slide relative to the guide grooves, so that the adjustment plate 41 can slide along the guide grooves to open and close the internal channel of the feed tube 2, thereby ensuring the sliding stability of the adjustment plate 41. There are two first tension springs 43, which are respectively located on the left and right sides of the adjustment plate 41, and the two first tension springs 43 are parallel to the screw rod 42, so that the screw rod 42 and the adjustment plate 41 can be balanced, and the structure is more stable. Among them, a tension spring accommodating groove is provided on the outer side of the feed tube 2 corresponding to the position of the first tension spring 43, the first tension spring 43 is placed in the tension spring accommodating groove, and the front end of the first tension spring 43 is connected to the bottom of the tension spring accommodating groove, and the rear end of the first tension spring 43 is connected to the end of the vertical plate 411. In the absence of external force, the first tension spring 43 will pull the adjustment plate 41 to slide in the closing direction through its own elastic force.

[0042] The feed delivery device of this embodiment is threadedly connected with the screw rod 42 and the vertical plate 411 of the adjustment plate 41, so that the adjustment plate 41 is not constrained by the screw rod 42. Figure 6 As shown, when in use, the user can directly pull the vertical plate 411 by hand to drive the adjustment plate 41 to slide backward so as to quickly open the adjustment plate 41, and under the engagement of the lock buckle 4121 and the block 111, the adjustment plate 41 can be locked in the open state. After pushing the vertical plate 411 forward to drive the lock buckle 4121 to disengage from the block 111, the first tension spring 43 will automatically pull the adjustment plate 41 to slide forward to the position where the front end of the screw rod 42 abuts against the outer side of the feeding tube 2, thereby realizing the automatic closing function of the adjustment plate 41 by the first tension spring 43, and under the abutment of the front end of the screw rod 42 against the outer side of the feeding tube 2, the adjustment plate 41 can be fixed at the adjusted position without sliding naturally.

[0043] As an improvement to the present embodiment, there are multiple regulating mechanisms, which are arranged from top to bottom, and are distributed around the feeding pipe 2 to ensure the structural balance of the feed delivery device. The number of regulating mechanisms can be set according to the number of breeding ponds. For example, the aquatic products cultured in the first pond are small shrimps, which require a smaller amount of feed; the aquatic products cultured in the second pond are medium shrimps, which require a medium amount of feed; and the aquatic products cultured in the third pond are large shrimps, so the amount of feed required is larger. Therefore, for the above three breeding ponds, the number of regulating mechanisms of the feed delivery device should be set to be greater than or equal to three.

[0044] During use, the user can pre-adjust the delivery amount of one of the adjustment structures to match the small shrimps, the delivery amount of another adjustment structure to match the medium shrimps, and the delivery amount of another adjustment structure to match the large shrimps. After pre-adjusting the delivery amount of each adjustment mechanism in this way, the adjustment plates 41 of all the adjustment structures are pulled open to the position where the lock 412 and the block 111 are engaged, so as to lock all the adjustment plates 41 in an open state. Among them, when it is necessary to feed the small shrimps, it is only necessary to release the lock of the adjustment plate 41 that matches the small shrimps, and the feed delivery can be adjusted to the delivery amount for the small shrimps. When it is necessary to feed the medium shrimps, the adjustment plate 41 that matches the small shrimps can be pulled to be fully opened, and then the lock of the adjustment plate 41 that matches the medium shrimps can be released, and the feed delivery can be adjusted to the delivery amount for the medium shrimps. The adjustment operation principle of large shrimps is the same as that of medium shrimps. In this way, users only need to adjust each adjustment mechanism once to meet the feeding requirements of multiple different types of aquatic products, and there is no need to repeat the daily feeding operation, which saves adjustment operation time and makes feeding very convenient.

[0045] Embodiment 3

[0046] This embodiment is a further improvement on the structure of the aquaculture feed delivery device of the second embodiment, and the improvement is that: Figure 7 , 8 As shown, a shield 5 is provided at the opening position of the lower end of the feed pipe 2, a discharge port 50 is provided on the side wall of the shield 5, a motor 51 is provided below the outer side of the shield 5, a rotating blade 52 is provided inside the shield 5, and the rotating blade 52 is connected to the rotating shaft of the motor 51. When in use, the feed is transmitted from the internal channel of the feed pipe 2 to the shield 5, and the rotating shaft of the motor 51 is driven by the rotating blade 52 to rotate, and the rotating blade 52 is rotated to send the feed out of the discharge port 50, so that the feed can be sent out by the rotating blade 52, and the feed can be put farther and more evenly.

[0047] like Figure 1 , 2As shown, the outer end of the sealing plate 3 is connected to a second tension spring 6 , and in the absence of external force, the second tension spring 6 will pull the sealing plate 3 to slide in the opening direction through its own elastic force, thereby realizing the automatic opening function of the sealing plate 3 .

[0048] like Figure 7 , 8 As shown in Figures 9 and 10, the feed delivery device further includes a locking mechanism for locking the sealing plate 3 in a closed state, the locking mechanism includes a base 71 disposed on the outside of the shield 5, a rotating block 72 rotatably connected to the base, an insertion rod 721 disposed on the left side wall of the rotating block 72, a push rod 722 disposed on the right side wall of the rotating block 72, a fixed seat 73 fixedly mounted on the outside of the feeding pipe 2 at a position corresponding to the outside of the L-shaped guide block 121, a support tube 74, and a transmission rod 741 passing through the support tube 74. The push rod 722 extends out of the base 71, and pushing the push rod 722 will drive the rotating block 72 to rotate, and rotating the rotating block 72 can drive the insertion rod 721 to insert into and out of the shield 5. The lower end of the support tube 74 is fixed to the outside of the base 71, and the upper end of the support tube 74 is fixed to the fixed seat 73. The lower end of the transmission rod 741 is connected to the rotating block 72, and the upper end of the transmission rod 741 can extend out and extend into the upper end of the support tube 74.

[0049] The side wall of the sealing plate 3 is provided with a locking groove 31. Figure 2 , 8 As shown, when the sealing plate 3 slides to the closed state and the insertion rod 721 is inserted into the protective cover 5, the upper end of the transmission rod 741 extends out of the upper end of the support tube 74 and is inserted into the locking groove 31 of the sealing plate 3. At this time, the upper end of the transmission rod 741 can block the locking groove 31 of the sealing plate 3, thereby locking the sealing plate 3 in the closed state. When the sealing plate 3 needs to be opened, the motor 51 can be turned on to drive the rotating blade 52 to rotate, and the rotating blade 52 will move the insertion rod 721 out of the protective cover 5, so that the rotating block 72 rotates to the right and pulls the upper end of the transmission rod 741 out of the locking groove 31 of the sealing plate 3. Figure 6 As shown, the locking of the sealing plate 3 is released, and the second tension spring 6 will automatically pull the sealing plate 3 to slide open, which is convenient to open. When the sealing plate 3 needs to be closed, the sealing plate 3 can be pushed forward by hand to the closed state, and at the same time, the push rod 722 is pushed to drive the insertion rod 721 to insert into the shield 5, so that the upper end of the transmission rod 741 is inserted into the locking groove 31 of the sealing plate 3, and the sealing plate 3 can be locked in the closed state.

[0050] like Fig. 9When the locking cam 720 is in the state of being moved forward, the locking cam 720 will be in the state of being moved forward, and the locking cam 720 of the locking cam 720 will be in the state of being moved forward.

[0051] In addition, the motor 51 of this embodiment can also be connected to a wireless remote controller, which can control the opening and closing of the motor 51. When in use, after the feed delivery device is placed on the boat, the user can use the wireless remote controller on the shore to control the motor 51 to open, and controlling the motor 51 to open is equivalent to operating the sealing plate 3 to open, which is very convenient.
