Description

Technical Field

[0001] The utility model relates to the technical field of silage additive spraying, in particular to a silage additive double spraying device and also to a silage machine adopting the silage additive double spraying device. Background Art

[0002] Silage has become an indispensable basic feed for ruminant feeding due to its many advantages such as high energy value, easy digestion, soft and fragrant, good palatability, long shelf life and low cost. The process of silage filling and storage involves the degradation of some nutrients in the feed, such as plant cell walls, and the fermentation of microorganisms, which will directly affect the quality of silage. Therefore, silage additives are often used in the process of silage processing to regulate the silage process. Silage additives are substances designed to inhibit the reproduction of undesirable microorganisms, reduce the loss of nutrients during storage, and ensure that silage is fermented within a predetermined range. There are many types of silage additives, which can be divided into three categories according to their effects: 1) Fermentation promoters, which mainly promote the fermentation of lactic acid bacteria to achieve the purpose of fresh-keeping storage, such as concentrated lactic acid bacteria; 2) Fermentation inhibitors, which mainly inhibit the activity of harmful microorganisms during silage fermentation, prevent the raw materials from mildewing and rotting, and reduce the loss of nutrients, such as formic acid, acetic acid, etc.; 3) Nutritional additives, which can improve the nutritional value of silage raw materials and improve the palatability of silage, such as urea diluents, minerals, etc.; and according to the use status, silage additives are basically divided into two categories: diluents and concentrates. Due to the diversity of additives, the characteristics of the feed itself vary greatly, and the required spraying dosage varies greatly, which inevitably forces users to equip spraying devices or equipment of different specifications to meet different spraying requirements according to actual conditions. For example, the spraying dosage of dilute additives is large, while the spraying dosage of concentrated lactic acid bacteria additives is small. If a single spraying system is used to spray both dilute and concentrated additives, the spraying dosage requirements cannot be met.

[0003] At present, domestic silage additives are basically still sprayed manually, that is, before the feed is placed in the pit, the additives are sprayed by manually carrying a sprayer. The spraying dosage and spraying uniformity cannot be guaranteed, and when multiple types of additives need to be sprayed, multiple people are required to work at the same time, the spraying efficiency is low and the labor intensity is high. Especially for concentrated fungus additives, they can usually only be diluted and sprayed, which is relatively unsuitable for feed with a high water content. If sprayed directly, not only can accurate dosage spraying not be achieved, but uniformity cannot be guaranteed, and the waste caused is even higher. In addition, the few silage machine products on the market that are equipped with a spraying system only use a simple device that uses a water tank and a water pump to operate the spraying. The spraying uniformity is poor and it cannot meet the diverse spraying needs of additives. Utility Model Content

[0028] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0029] It is understandable that Figure 1 and Figure 2 As shown, the preferred embodiment of the utility model provides a silage additive double spraying device, comprising:

[0030] Large flow spraying system, used for spraying diluted additives;

[0031] Small flow spraying system, used for spraying concentrated additives;

[0032] The large flow spraying system is also connected to the small flow spraying system, and a first switch valve 1 is provided on the pipeline connecting the two;

[0033] The controller 100 is electrically connected to the first switch valve 1, the large flow spraying system and the small flow spraying system, and is used to switch between the independent spraying mode and the mixed spraying mode by controlling the on and off of the first switch valve 1. When the controller 100 controls the first switch valve 1 to be closed, it switches to the independent spraying mode, and then controls the large flow spraying system and / or the small flow spraying system to work according to the actual spraying demand, so that the diluted additive and the concentrated additive can be sprayed separately; and when the controller 100 controls the first switch valve 1 to be opened, the large flow spraying system is connected to the small flow spraying system, and then controls the large flow spraying system and / or the small flow spraying system to work, so as to realize the mixed spraying of the diluted additive and the concentrated additive.

[0034] It can be understood that the silage additive double spraying device of this embodiment is provided with two spraying systems for spraying the dilute additive and the concentrated additive respectively, which can meet the large-dose spraying demand of the dilute additive and the small-dose spraying demand of the concentrated additive, and the two spraying systems are connected through the first switch valve 1. When the first switch valve 1 is controlled to be closed, the two spraying systems are separated from each other, and the separate spraying of the dilute additive and the concentrated additive can be realized. When the first switch valve 1 is controlled to be opened, the two spraying systems are connected, so that the mixed spraying of the dilute additive and the concentrated additive can be realized, which is suitable for dry feed that requires spraying concentrated liquid additives to improve fermentation and needs to increase moisture, so as to meet a variety of additive spraying needs. In addition, the entire spraying process is automated, and it can be sprayed directly during the silage harvesting process. After the silage is harvested, it can be directly put into the cellar, which greatly improves the work efficiency compared with the manual spraying method after entering the cellar.

[0035] Specifically, the high-flow spraying system includes a diluent water tank 2 and at least one high-flow nozzle 6. The liquid outlet of the diluent water tank 2 is connected to the at least one high-flow nozzle 6. The pipeline connecting the two is sequentially provided with a first stop valve 3, a flow meter 4 and a main water pump 5. The diluent water tank 2 is used to store diluent additives, the first stop valve 3 is used to control the on-off of the infusion pipeline, the flow meter 4 is used to detect the flow rate of the diluent additive transported in the pipeline, and the main water pump 5 is used to pressurize and transport the diluent additive to ensure the spraying pressure at the high-flow nozzle 6, thereby improving the spraying uniformity. The high-flow nozzle 6 is used to spray the diluent additive uniformly into the silage. Among them, the first stop valve 3, the flow meter 4 and the main water pump 5 are all electrically connected to the controller 100. When the controller 100 controls the first stop valve 3 to open and controls the main water pump 5 to work, the diluted additive stored in the diluent water tank 2 can be pressurized and transported to the large-flow nozzle 6 for uniform spraying. In addition, the controller 100 can also control the working state of the main water pump 5 according to the flow monitoring result of the flow meter 4 to realize the flow regulation of the large-flow spraying system, improve the accuracy of the spraying dosage of the diluted additive, and realize the stable output of the large-flow additive, thereby improving the spraying uniformity.

[0036] Optionally, a regulating valve 7 is also provided in front of each large flow nozzle 6, and the regulating valve 7 is electrically connected to the controller 100. The controller 100 is also used to achieve flow distribution adjustment between multiple large flow nozzles 6 by controlling the opening of each regulating valve 7, which is conducive to further improving the spraying uniformity between multiple large flow nozzles 6. In addition, the large flow spraying system also includes a first filter 8 for filtering additives, and the first filter 8 is specifically located between the first stop valve 3 and the flow meter 4. In addition, a first liquid level detection device 9 electrically connected to the controller 100 is provided in the diluent water tank 2. The controller 100 is also used to send an alarm signal when the first liquid level detection device 9 detects that the liquid level in the diluent water tank 2 is lower than a threshold value, reminding the staff to replenish the diluent additive in the diluent water tank 2 in time, thereby improving the reliability of the system. Among them, the first liquid level detection device 9 can adopt a liquid level sensor or a liquid level meter.

[0037] In addition, the small flow spraying system includes a concentrate tank 10 and at least one small flow nozzle 11, the liquid outlet of the concentrate tank 10 is connected to the at least one small flow nozzle 11, and the pipeline connecting the two is sequentially provided with a second stop valve 12, an auxiliary water pump 13, and a second switch valve 14, and the second switch valve 14 is located after the connection position between the first switch valve 1 and the small flow spraying system. The concentrate tank 10 is used to store concentrated additives, the small flow nozzle 11 is used to spray the concentrated additives uniformly into the silage, the second stop valve 12 is used to control the on-off of the delivery pipeline, the auxiliary water pump 13 is used to pressurize and deliver the concentrated additives to ensure the spraying pressure at the small flow nozzle 11, and improve the spraying uniformity, and the second switch valve 14 is used to control whether the concentrated additive is delivered to the small flow nozzle 11. The second stop valve 12, the auxiliary water pump 13 and the second switch valve 14 are electrically connected to the controller 100.

If the first switch valve 1 is controlled to be closed and the second switch valve 14 is controlled to be opened, the pressurized concentrated additive is directly transported to the small flow nozzle 11 for uniform spraying. If the first switch valve 1 is controlled to be opened and the second switch valve 14 is controlled to be closed, the pressurized concentrated additive is transported to the large flow spraying system to mix with the diluted additive. The mixed additive is then continuously pressurized and transported to the large flow nozzle 6 via the main water pump 5 to achieve uniform mixing and spraying. In addition, the controller 100 also realizes flow regulation of the small flow system by controlling the working state of the auxiliary water pump 13.

[0038] In addition, the small flow spraying system also includes a second filter 15 for filtering the additive, and the second filter 15 is specifically located between the second stop valve 12 and the auxiliary water pump 13. In addition, the concentrate tank 10 is provided with a second liquid level detection device 16 and a temperature detection device 17 electrically connected to the controller 100.
