Description

Technical Field

[0001] This invention belongs to the technical field of automatic spraying devices, specifically, it relates to an automatic spraying device for alfalfa silage additives. Background Technology

[0002] Alfalfa is an indispensable high-quality protein forage for the development of animal husbandry. Alfalfa is a type of alfalfa. In order to improve the silage effect and ensure the quality of silage, additives that are conducive to the fermentation of silage raw materials and can improve the quality of silage feed are often used when making alfalfa silage. Silage additives are added during the process of picking, chopping or wrapping and bundling the raw materials. When adding, they should be sprayed evenly on the alfalfa raw materials.

[0003] Existing automatic alfalfa silage additive spraying devices, such as the utility patent with patent application number CN202222197710.0 entitled "Automatic Spraying Device for Alfalfa Silage Additives," disclose an automatic spraying device for alfalfa silage additives, including an additive tank, a movable base, a storage tank, a lifting platform, a top plate, a fixed base, a spraying box, and a drive mechanism. The additive tank stores additives and is connected to a liquid outlet pipe. The bottom of the movable base is equipped with multiple casters with self-locking structures. The storage tank is fixedly connected to the top of the movable base and is connected to a liquid inlet pipe and a water pump. The lifting platform is connected to the top of the base via a lifting mechanism, and the top plate is fixedly connected to the top of the lifting platform. The fixed base is connected to the storage tank via a connecting pipe and to the outlet of the water pump via a liquid delivery pipe. Valves are installed on both the connecting pipe and the liquid delivery pipe. The spraying box is rotatably connected to the bottom of the fixed base via a rotating pipe, and multiple nozzles are connected to the bottom of the spraying box. The drive mechanism is connected to the top plate.

[0004] This utility model has high spraying efficiency and short spraying time, making it suitable for large-scale alfalfa silage production.

[0005] The above-mentioned device enables the spraying of additives on alfalfa silage. However, when in use, it only sprays on the surface of alfalfa, and the mixing effect between alfalfa and additives is poor. Therefore, existing spraying devices store alfalfa in a mixing tank and spray additives while mixing alfalfa.

[0006] Because alfalfa absorbs liquid additives, some alfalfa absorbs a large amount of additives and adheres to the inside of the mixing tank. At this point, the alfalfa, containing a large amount of liquid additives, is very sticky and difficult to fall off. This also reduces the amount of liquid additives absorbed by the remaining alfalfa, making it difficult to mix the alfalfa with the additives. Furthermore, when spraying the additives, some liquid additives will accumulate at the bottom of the mixing tank. If these additives are not collected, they will be discharged with the mixed alfalfa, which is not conducive to the recycling and reuse of the additives and will result in waste.

[0007] In view of this, the present invention is proposed. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic spraying device that can overcome or at least partially solve the above problems.

[0009] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: It includes a shell and a liquid storage tank, with a stirring shaft rotatably connected inside the shell and a water pump connected inside the liquid storage tank. The invention is characterized by further comprising:

[0010] Multiple sets of fixing rods are fixedly connected to the housing, and multiple sets of atomizing nozzles are fixedly connected to the fixing rods;

[0011] The liquid outlet pipe is fixedly connected to the liquid outlet end of the water pump, and the liquid outlet end of the liquid outlet pipe is fixedly connected to the atomizing nozzle.

[0012] Multiple sets of protrusions are fixedly connected inside the housing;

[0013] A sliding block is slidably connected inside the fixed rod. A return spring is connected to the sliding block, and the other end of the return spring is connected to the fixed rod. The sliding block is in contact with the protrusion.

[0014] A recycling bin is fixedly connected to the bottom of the housing. The bottom of the housing has multiple sets of holes, and the other end of each hole communicates with the recycling bin.

[0015] Multiple sets of fixing blocks are fixedly connected inside the recycling bin, and compression springs are connected to the fixing blocks;

[0016] A filter screen is installed at an angle inside the recycling bin, and the filter screen is connected to a compression spring;

[0017] An auxiliary tapping device is installed inside the recycling bin to tap the filter screen.

[0018] To facilitate tapping the filter screen and move some of the alfalfa on the screen so that it can be discharged; further, the auxiliary tapping device includes: a bushing and a tapping rod, one end of the stirring shaft penetrates the housing and the penetrating end is located inside the recycling box, the penetrating end of the stirring shaft is provided with a reciprocating thread, the bushing is threadedly connected to the reciprocating thread, the tapping rod is fixedly connected to the bushing, and one end of the tapping rod is in contact with the filter screen.

[0019] To facilitate the up-and-down reciprocating movement of the auxiliary striking device, a limiting rod is fixedly connected to the bottom of the housing, and the limiting rod passes through the striking rod.

[0020] To facilitate the rotation of the stirring shaft, a drive motor is fixedly connected to the housing, and a transmission gear one is fixedly connected to the output end of the drive motor. A transmission gear two is meshed with the transmission gear one, and the transmission gear two is fixedly connected to the stirring shaft.

[0021] To facilitate the falling and discharge of any remaining alfalfa from the pores by striking the bottom of the housing, a push rod is fitted onto the compression spring. The push rod is connected to the compression spring, and one end of the push rod passes through the filter screen, with the through end of the push rod in contact with the bottom of the housing.

[0022] In order to recover the additive liquid after recycling; furthermore, the inlet end of the water pump is fixedly connected to an inlet pipe, the inlet end of the inlet pipe is located inside the recovery tank, and a control valve is connected to the end of the inlet pipe inside the recovery tank.

[0023] To facilitate the pump extraction of additives from the storage tank, a branch inlet pipe is connected to the inlet pipe, which is located inside the storage tank.

[0024] To facilitate the feeding of alfalfa and the discharge of alfalfa after mixing with additives, the shell is further equipped with a feed inlet and a discharge outlet. The discharge end of the feed inlet is located below the fixed rod, and a rotary valve is connected inside the discharge outlet.

[0025] To facilitate the discharge of alfalfa filtered through the filter screen, the recycling bin is further provided with a discharge port located at the lower end of the filter screen.

[0026] To facilitate centralized recycling of alfalfa after mixing with additives, a collection box is further provided below the discharge port, and the collection box is located below the discharge port.

[0027] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention, through the setting of the fixing rod, facilitates the spraying of additives on alfalfa inside the shell by rotation, promoting the spraying effect. At the same time, the rotation will knock the protrusion, and the resulting vibration will cause the alfalfa adhering to the shell to fall off, which is conducive to the thorough mixing of the more moist alfalfa and the more dry alfalfa. Meanwhile, the setting of the bottom recycling box can recover the additives accumulated at the bottom of the shell, avoiding the waste of additives, saving resources, and facilitating the spraying of alfalfa additives.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] Example 1:

[0042] Reference Figure 1-7 An automatic spraying device for alfalfa silage additive includes a housing 1 and a storage tank 2. A stirring shaft 104 is rotatably connected inside the housing 1, and a water pump 201 is connected inside the storage tank 2. The device also includes: multiple sets of fixing rods 105 fixedly connected to the housing 1, with multiple sets of atomizing nozzles 106 fixedly connected to the fixing rods 105; a liquid outlet pipe 203 fixedly connected to the liquid outlet end of the water pump 201, with the liquid outlet end of the liquid outlet pipe 203 fixedly connected to the atomizing nozzles 106; multiple sets of protrusions 107, all fixedly connected inside the housing 1; and a sliding block 1. 08, a sliding block 108 is slidably connected within the fixed rod 105, and a return spring 109 is connected to the sliding block 108. The other end of the return spring 109 is connected to the fixed rod 105, and the sliding block 108 is in contact with the protrusion 107; a recycling bin 3 is fixedly connected to the bottom of the housing 1, and the bottom of the housing 1 is provided with multiple sets of holes 301, the other end of which communicates with the recycling bin 3; multiple sets of fixed blocks 302 are fixedly connected within the recycling bin 3, and compression springs 303 are connected to the fixed blocks 302; a filter screen 304 is inclinedly installed in the recycling bin 3. Inside, the filter screen 304 is connected to the compression spring 303; an auxiliary striking device is installed inside the recycling bin 3 to strike the filter screen 304; a drive motor 103 is fixedly connected to the housing 1, and a transmission gear 1031 is fixedly connected to the output end of the drive motor 103. A transmission gear 1041 is meshed on the transmission gear 1031, and the transmission gear 1041 is fixedly connected to the stirring shaft 104; an inlet pipe 202 is fixedly connected to the inlet end of the water pump 201, and the inlet end of the inlet pipe 202 is located in the recycling bin 3. Inside, the liquid inlet pipe 202 is connected to a control valve at one end inside the recovery tank 3; a liquid inlet branch pipe is connected to the liquid inlet pipe 202, which is located inside the liquid storage tank 2; a feed inlet 101 and a discharge outlet 102 are fixedly connected to the shell 1, the discharge end of the feed inlet 101 is located below the fixed rod 105, and a rotary valve is connected inside the discharge outlet 102; the recovery tank 3 is provided with a discharge outlet 305, which is located at the lower end of the filter screen 304, and a collection box 4 is provided below the discharge outlet 102, which is located below the discharge outlet 305.

[0043] In use, alfalfa to be sprayed with additives is poured into the housing 1 through the inlet 101. Then, the drive motor 103 is started, and the meshing of transmission gears 1031 and 1041 causes the stirring shaft 104 to rotate. The water pump 201 then starts, drawing liquid additives from the storage tank 2 and discharging them through the outlet pipe 203. The additives ultimately enter the atomizing nozzle 106 on the fixed rod 105 and are sprayed out through the atomizing nozzle 106. At this time, due to the fixed rod 105... When rotating, the atomized additive sprayed from the atomizing nozzle 106 will be further dispersed, promoting the mixing effect of the liquid additive and alfalfa. Simultaneously, due to the rotation of the stirring shaft 104, the alfalfa inside the housing 1 will be stirred, further promoting the mixing effect of the alfalfa and additive. As the fixing rod 105 rotates, the sliding block 108 will contact the protrusion 107. At this time, the sliding block 108 will move under the influence of the protrusion 107, squeezing the return spring 109 behind it. Subsequently, as the sliding block 108 moves away from the protrusion 107, the return spring 109 returns to its original position, thus resetting the sliding block 108. This causes the housing 1 to be struck, generating vibration that is transmitted downwards, thus vibrating any alfalfa that may be adhering to the housing 1. Since most of the alfalfa adhering to the inside has absorbed a large amount of liquid additive, the adhesion between the alfalfa and the inside of the housing 1 decreases with each strike, and some of the liquid additive inside the alfalfa will flow down and fall onto the alfalfa below. The continuous tapping of 108 and the rotation of the stirring shaft 104 cause the remaining alfalfa to pull against each other, which can pull down the alfalfa adhering to the inner wall. This allows the alfalfa adhering to the inner wall to come into contact with the still-dry or insufficiently mixed alfalfa with the additive, which facilitates the full mixing of alfalfa and additive and makes it easier to spray alfalfa. This avoids the alfalfa on the inner wall absorbing a large amount of liquid, which would result in insufficient contact between the remaining alfalfa and the additive, saving time and avoiding the waste of additives.

[0044] As the atomizing nozzle 106 continuously sprays the additive onto the alfalfa, some liquid additive accumulates at the bottom of the housing 1. At this time, the additive flows into the recycling tank 3 below through the hole 301. The liquid carries some small alfalfa fragments. Due to the filter screen 304, the liquid additive is separated from the alfalfa fragments. The alfalfa fragments remain on the filter screen 304. Due to the auxiliary tapping device, the filter screen 304 is tapped, causing the compression spring 303 to be compressed and then continuously bounced up, promoting the discharge of alfalfa fragments from the filter screen 304. This allows the alfalfa fragments to be discharged through the discharge port 305, facilitating the separation of alfalfa from the liquid additive and enabling the subsequent direct recycling and reuse of the additive.

[0045] If alfalfa has been sprayed for a certain period of time, there will be a certain amount of filtered additives in the recovery box 3. At this time, the control valve in the liquid inlet pipe 202 can be opened to allow the water pump 201 to draw the additives in the recovery box 3 and spray them out again through the atomizing nozzle 106, which facilitates the recycling and reuse of the additives.

[0046] After stirring and spraying the alfalfa with additives inside the shell 1 for a certain period of time, the water pump 201 can be turned off. Stirring can be continued for a certain period of time to promote the mixing effect of alfalfa and additives. Finally, the rotary valve on the discharge port 102 can be turned. At this time, the drive motor 103 is running, and the alfalfa inside the shell 1 will be discharged through the discharge port 102 and finally fall into the collection box 4 below for centralized collection. The alfalfa sprayed with additives can then be packaged for silage.

[0047] To facilitate automation, a PLC system can be installed. This device can control the amount of silage entering the housing 1, control the usage time and power of the water pump 201, and control the additives sprayed by the atomizing nozzle 106. This facilitates automated feeding, spraying, mixing, and discharging of alfalfa, freeing up labor.

[0048] Example 2:

[0049] Reference Figure 1-5 An automatic spraying device for alfalfa silage additive is basically the same as in Example 1, but with a further improvement: the auxiliary striking device includes: a bushing 1042 and a striking rod 1043. One end of the stirring shaft 104 passes through the housing 1 and the passing end is located inside the recycling box 3. The passing end of the stirring shaft 104 is provided with a reciprocating thread. The bushing 1042 is threadedly connected to the reciprocating thread. The striking rod 1043 is fixedly connected to the bushing 1042. One end of the striking rod 1043 is attached to the filter screen 304. A limiting rod 1044 is fixedly connected to the bottom of the housing 1 and passes through the striking rod 1043.

[0050] The rotation of the stirring shaft 104 causes the reciprocating thread to rotate, which in turn causes the bushing 1042 to move up and down under the action of the reciprocating thread. This causes the striking rod 1043 to continuously strike the filter screen 304 below as the bushing 1042 moves back and forth. This causes the filter screen 304 to move downward under force, squeezing the compression spring 303 below and generating vibration. This causes the alfalfa debris on the filter screen 304 to jump up continuously and finally be discharged through the discharge port 305.

[0051] Example 3:

[0052] Reference Figure 1-4An automatic spraying device for alfalfa silage additive is basically the same as in Example 2, but with a further improvement: a top rod 3031 is sleeved on the compression spring 303, the top rod 3031 is connected to the compression spring 303, and one end of the top rod 3031 passes through the filter screen 304. The through end of the top rod 3031 is in contact with the bottom of the housing 1. The number of top rods 3031 can be set in multiple groups, such as side by side, to improve the knocking effect.

[0053] In this device, as the stirring shaft 104 rotates, the auxiliary striking device will strike the filter screen 304, causing the alfalfa debris on the filter screen 304 to be discharged. At the same time, as the filter screen 304 is squeezed, the compression spring 303 is squeezed. As the auxiliary striking device moves away, the compression spring 303 quickly extends. At this time, the top rod 3031 will strike the bottom of the housing 1, which will generate a certain vibration, making it easier for the alfalfa adhering to the housing 1 to fall off. At the same time, since the top rod 3031 is close to the hole 301, some alfalfa debris that may be adhering in the hole 301 will fall onto the filter screen 304 below, preventing the hole 301 from being blocked.

[0054] The present invention, through the setting of the fixing rod 105, facilitates the spraying of additives on alfalfa inside the shell 1 by rotation, thereby promoting the spraying effect. At the same time, the rotation will strike the protrusion 107, and the resulting vibration will cause the alfalfa adhering to the shell 1 to fall off, which will facilitate the thorough mixing of the more moist alfalfa and the drier alfalfa. Meanwhile, the setting of the bottom recycling box 3 can recover the additives accumulated at the bottom of the shell 1, avoid the waste of additives, save resources, and facilitate the spraying of alfalfa additives.
