Design, construction and evaluation of semi-automatic vegetable transplanter with conical distributor cup

Abstract

In this research, in order to increase the speed and precision of cultivation, the semi-automatic tomato transplanter with conical distributor cup was designed and constructed. In this machine, transplants are transmitted by a semi-automatic distributor and through the conical bowls into the fall tube and transferred to the furrow formed by the furrower. In the field evaluation of the machine, these parameters were considered: the distance between the cultivated seedling, cultivation depth and angle, and the amount of physical damage to seedlings. The tests were carried out using a factorial experiment based on a completely randomized block design with ten replications. The treatments consisted of three levels of forward speed, including speed of 1, 2 and 3 km h −1 and two levels of cultivation depth at 5 and 10 cm. The results showed that interaction between the forward speed and the cultivation depth had no significant effect on the variables studied, the factor of forward speed had significant effects only on the variables of deployment angle and physical damage to the seedlings, and the factor of cultivation depth was only effective on the variable of the seedling deployment angle. The most appropriate forward speed and cultivation depth were 2 km h −1 and 5 cm, respectively. With a forward speed of 2 km h −1 and in one cultivation row, a theoretical capacity of 0.008 hah −1 was determined for the machine.forward speed of 2 km h −1 and the distance of 40 cm, the theoretical capacity of 0.88 hah −1 can be achieved.

Experimental Research and Analysis of Soil Disturbance Behavior during the Hole Drilling Process of a Hanging-Cup Transplanter by DEM

“…The existing research has mainly focused on the optimal design of planters and holesize parameters. For example, Seyed et al [6] designed and created a conical distribution cup to improve planting speed and precision and conducted field tests. Dihingia et al [7] developed a planting device for a vegetable transplanter driven by a walking tractor and conducted experimental research.…”

“…Mechanization of transplanting refers to the decrease in manpower requirements in cultivating operations that give the least amount of seedling damage and the highest level of cultivating efficiency [ 12 ]. Although several mechanized transplanters are available in the market, they are costly and require additional power consumption [ [13] , [17] , [18] , [19] ]. For countries like Bangladesh, mechanized planters should be affordable so local farmers can widely adopt them.…”

Development of Dibble Mechanism for Tractor Operated Two Row Semi – Automatic Vegetable Transplanter

“…While fullyautomatic transplanters offer efficiency, they are complex and require skilled labour, leading to higher initial costs. Semi-automatic transplanters, however, prove to be suitable for Indian conditions, striking a balance between time and labour efficiency and cost-effectiveness [8,9]. The current study focuses on a low-cost, tractoroperated, two-row semi-automatic vegetable transplanter with linear operating dibblers, aiming to overcome challenges associated with furrow openers on mulches during seedling transplantation.…”
