Description

Technical Field

[0001] The utility model belongs to the technical field of fertilization, and in particular relates to a quantitative liquid fertilizer applying device. Background Art

[0002] Tobacco plants need to be top-dressed several times during their growth in the field. The corresponding fertilizers can be applied in the form of fixed fertilizers around the tobacco plants or by dissolving solid fertilizers in a certain proportion and directly watering them with liquid fertilizers. The former is easier to operate, but the wrong fertilization position can easily cause seedling burning and root rot, while the latter releases fertilizer more gently, but it is difficult to achieve quantitative application. There are also operations in the prior art that use mechanized equipment for quantitative fertilization, but the overall cost is relatively high, and some special terrains such as sloping land and semi-sloping land are difficult to apply mechanical operations. Therefore, tobacco farmers often choose to carry buckets and scoop liquid fertilizers through homemade containers for watering, and the overall operation efficiency is low. Utility Model Content

[0003] The utility model provides a quantitative liquid fertilizer application device. The utility model improves the structure of an existing backpack sprayer and realizes rapid acquisition of quantitative liquid fertilizer for irrigation through a quantitative box, thereby ensuring the application efficiency and effect of the liquid fertilizer.

[0004] To solve the above problems, the utility model adopts the following technical solutions.

[0005] A quantitative liquid fertilizer application device comprises a connecting pipe connected to a backpack liquid storage tank, the output end of the connecting pipe is connected to a fertilizer cylinder, and the input end of the connecting pipe is provided with a quantitative box;

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-4 As shown, a quantitative liquid fertilizer application device includes a connecting tube 200 connected to a backpack liquid storage tank 100 and supported by a hard material for hand-holding, the output end of the connecting tube 200 is connected to a fertilizer barrel 201, a bearing is preset on the top wall of the fertilizer barrel 201, the bearing is rotatably matched with the outer wall of the connecting tube 200, and the output end of the connecting tube 200 is connected to a telescopic hose arranged near the inner wall of the fertilizer barrel 201; a quantitative box 202 is provided at the input end of the connecting tube 200, and the quantitative box 202 is connected to the liquid storage tank 100 through a connecting hose 203, the liquid storage tank 100 is provided with a liquid filling port 102 for adding liquid fertilizer, shoulder straps 101 are provided on both sides of the liquid storage tank 100, and a control valve 204 is installed on the connecting hose 203. A mounting frame 103 is detachably connected to one side of the liquid storage box 100 . An inserting slot 104 for inserting the quantitative box 202 is provided at the upper end of the mounting frame 103 . A through slot 105 for penetrating the connecting hose 203 is provided at the bottom of the inserting slot 104 .

[0022] Openings are provided at both ends of the quantitative box 202, and the two openings are respectively blocked by a first blocking plate 206 and a second blocking plate 208. The inside of the quantitative box 202 is also rotatably connected to the first rotating rod 205 and the second rotating rod 207 at the two openings. The first blocking plate 206 and the second blocking plate 208 are respectively fixedly connected to the first rotating rod 205 and the second rotating rod 207. The same-direction ends of the first rotating rod 205 and the second rotating rod 207 pass through the quantitative box 202 and are coaxially fixed with a linkage gear 209. The two linkage gears 209 are driven by a linkage chain 210. After the end of the first rotating rod 205 or the second rotating rod 207 away from the linkage gear 209 passes through the quantitative box 202, a toggle wheel 211 is fixedly provided.

[0023] The first plugging plate 206 is in the state of opening the corresponding opening, and the second plugging plate 208 is in the state of closing the corresponding opening; the first plugging plate 206 is in the state of closing the corresponding opening, and the second plugging plate 208 is in the state of opening the corresponding opening. The shoulder strap 101 allows the liquid storage tank 100 to be carried on the back of the fertilizer applicator, and the tightness can be adjusted according to the body shape. In this embodiment, the liquid filling port 102 is opened to add liquid fertilizer to the inside of the liquid storage tank 100, and the liquid fertilizer is transported to the inside of the fertilizer barrel 201 through the connecting pipe 200 and the telescopic hose. At the same time, the rotation setting of the connecting pipe 200 and the fertilizer barrel 201 can ensure that the fertilizer barrel 201 can keep the top open at all times facing upward under the action of gravity, thereby preventing the fertilizer in the fertilizer barrel 201 from tipping over due to the wrong posture of the fertilizer applicator. The fertilizer applicator holds the connecting pipe 200 and puts the fertilizer barrel 201 against the tobacco ridge to irrigate the liquid fertilizer inside to the roots of the tobacco plants. When fertilizing, the liquid fertilizer inside the liquid storage tank 100 enters the interior of the quantitative box 202 through the connecting hose 203, and the liquid fertilizer remains in the quantitative box 202 until it is full due to the blocking of the second sealing plate 208. When fertilizing, the fertilizer applicator holds the outside of the connecting tube 200 close to the first sealing plate 206, and uses the thumb to turn the toggle wheel 211 to close the first sealing plate 206, and opens the second sealing plate 208 on the other side through the cooperation of the linkage gear 209 and the linkage chain 210. At this time, the liquid fertilizer enters the interior of the fertilizer barrel 201 through the connecting tube 200, so as to carry out fertilization, so that the tobacco seedlings can be fertilized in a quantitative manner.

[0024] The connecting hose 203 allows the connecting pipe 200 and the fertilizer barrel 201 to move freely, and the control valve 204 can be closed to prevent the liquid fertilizer inside the liquid storage tank 100 from flowing into the fertilizer barrel 201. The quantitative box 202 can control the liquid fertilizer entering the fertilizer barrel 201, thereby achieving quantitative fertilization and making fertilization more convenient.

[0025] By providing the mounting frame 103, the plug slot 104 and the through slot 105, the connecting pipe 200 and the fertilizer cylinder 201 are relatively fixed to the liquid storage tank 100 when the device is not in use, so that it can be stored and carried more conveniently.

[0026] The same principle is used for root irrigation with quantitative drugs and the like.

[0027] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
