Description

Technical Field

[0001] The utility model relates to a linear propulsion device for a floating plate used in a hydroponic bed, and belongs to the technical field of linear propulsion of a floating plate used in a hydroponic bed. Background Art

[0002] Hydroponics is an important branch of soilless cultivation. With the development of facility agriculture technology, new factory-based soilless cultivation technology represented by Deep Flow Technique (DFT) is becoming more and more widely used. Vegetables no longer grow in the soil, but in foam floating boards. The foam floating boards float in the hydroponic beds, which are filled with nutrient solution. The roots absorb nutrients from the clean nutrient solution. The clean vegetables produced by this technology are widely praised by consumers.

[0003] The hydroponic bed is generally a large rectangular pool, and the floating boards planted with crops are arranged in the hydroponic bed. A linear propulsion device is provided at the input end of the hydroponic bed, which is transported to the input end of the hydroponic bed through the floating board conveyor line, and then the floating board is pushed into the hydroponic bed by the linear propulsion device. Under the mutual pushing of the floating boards, the floating boards at the harvesting end of the hydroponic bed are squeezed out, and the floating boards are discharged. The existing linear propulsion device can only propel the floating boards by a distance of the width of a floating board (about 500mm). Only when the hydroponic bed is full of floating boards, the floating boards can be discharged from the harvesting end through the mutual squeezing of the floating boards. When the floating boards in the hydroponic bed are not full, the crops cannot be harvested. In addition, there are generally multiple rows of floating boards in a hydroponic bed, and one row of floating boards needs to be equipped with a set of linear propulsion devices, and a set of linear propulsion devices is expensive and not economical.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A floating plate linear propulsion device for a hydroponic bed comprises a hydroponic bed, wherein an input end and a harvesting end inside the hydroponic bed are respectively provided with an input end rotating shaft and a harvesting end rotating shaft, wherein transmission pulleys are respectively installed on the input end rotating shaft and the harvesting end rotating shaft, a transmission belt is wound between the transmission pulleys at both ends, a push plate mechanism is installed on the upper end of the transmission belt, and the transmission belt drives the push plate mechanism to reciprocate.

DETAILED DESCRIPTION

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0027] like Figure 1-3 As shown, the utility model provides a floating plate linear propulsion device for a hydroponic bed, comprising a hydroponic bed 1, wherein the input end and the harvesting end of the hydroponic bed 1 are respectively provided with an input end rotating shaft 4 and a harvesting end rotating shaft 5, wherein the input end rotating shaft 4 and the harvesting end rotating shaft 5 are respectively provided with a transmission pulley 6, a transmission belt 7 is wound between the transmission pulleys 6 at both ends, a push plate mechanism 9 is installed at the upper end of the transmission belt 7, and the transmission belt 7 drives the push plate mechanism 9 to reciprocate. Since the push plate mechanism 9 can move within the entire length of the hydroponic bed 1, when the floating plates in the hydroponic bed 1 are not fully covered, the push plate mechanism 9 can also push the floating plates so that the floating plates are pushed out from the harvesting end.

[0028] A mounting frame 2 is provided at the input end of the hydroponic bed 1, and a driving system 3 is provided on the top of the mounting frame 2. A driving motor and a reduction unit are installed in the driving system 3. A driving wheel 12 and a transition wheel 13 are installed on the power output shaft of the driving system 3. The driving wheel 12 and the transition wheel 13 are driven by a belt. A passive wheel 14 is also provided on the input end rotating shaft 4. The passive wheel 14 and the transition wheel 13 are driven by a belt. The driving wheel 12 drives the transition wheel 13 to rotate, thereby driving the passive wheel 14 to rotate, and the passive wheel 14 drives the input end rotating shaft 4 to rotate, so that the transmission belt 7 pulls the push plate mechanism 9 to reciprocate.

[0029] A torque sensor (not shown) is provided on the power output shaft of the drive system 3. When the push plate mechanism 9 pushes the floating plate so that the floating plate is pushed out from the harvesting end, the push plate mechanism 9 receives resistance, and the torque sensor transmits the torque to the electronic control system, which controls the drive system 3 to shut down.

[0030] There are multiple transmission pulleys 6 along the axial direction of the input end rotating shaft 4 and the harvesting end rotating shaft 5, respectively. A transmission belt 7 is wound between the transmission pulley 6 on each input end rotating shaft 4 and the corresponding transmission pulley 6 on the harvesting end rotating shaft 5, and a push plate mechanism 9 is installed on the transmission belt 7.

[0031] A plurality of partition plates 10 are provided inside the hydroponic bed 1 along its length direction. The partition plates 10 divide the hydroponic bed 1 into a plurality of cultivation areas. Each cultivation area is provided in one-to-one correspondence with each push plate mechanism 9 .

[0032] The partition plate 10 is rotatably mounted with a plurality of rollers 11, so that the floating plate can move more smoothly.

[0033] A fixing block 8 is fixed on the transmission belt 7 , and the fixing block 8 is fixedly connected to the push plate mechanism 9 .

[0034] like Figure 4 , Figure 5 The push plate mechanism includes a fixed base plate 15, on which a push plate 16 is rotatably mounted, two limiting holes 19 are arranged on each side of the push plate 16, a first limiting pin 17 is arranged on the upper side of the fixed base plate 15, and a second limiting pin 18 is arranged on the lower side of the fixed base plate 15. When the floating plate needs to be pushed by the push plate 16, the push plate 16 and the fixed base plate 15 are in a vertical state (such as Figure 4 ), insert the first limit pin 17 into the limit hole 19 at the upper end of the push plate 16; when the floating plate does not need to be pushed by the push plate 16, make the push plate 16 in a horizontal state (such as Figure 5 ), insert the second limiting pin 18 into the limiting hole 19 at the lower end of the push plate 16.

[0035] The specific working principle of the utility model:

[0036] The partition plate 10 divides the hydroponic bed 1 into multiple cultivation areas, and each cultivation area is provided with a push plate mechanism 9. The push plate mechanism 9 moves back and forth driven by the transmission belt 7 to push the floating plate to the harvesting end. Since the push plate mechanism 9 can move within the entire length of the hydroponic bed 1, when the floating plates in the hydroponic bed 1 are not fully covered, the push plate mechanism 9 can also push the floating plates to be pushed out from the harvesting end.

[0037] The push plate mechanism 9 includes a fixed base plate 15 and a push plate 16. Since the multiple push plate mechanisms 9 reciprocate simultaneously, when pushing the floating plate, generally only the floating plate in one cultivation area is pushed at a time. At this time, the push plate 16 of the push plate mechanism 9 in this cultivation area is set to a vertical state, and the push plates 16 of the push plate mechanisms 9 in other cultivation areas are set to a horizontal state. In this way, a set of driving systems 3 can be used to push the floating plates in all cultivation areas, thereby reducing investment costs.

[0038] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
